SMoking VFL

You know that scene from lord of the rings where bilbo is chillin with Gandalf ,blowing smoke rings. All of a sudden this guy just blows a friggin ship from out of nowhere, bilbo just hangs and stares. 

Thats the exact same feeling when looking at a friggin VFL sample from ANywhere. So battling with this for a while I decided to write a SUPER high level dummy guide to constraints.

So first things first, why is your app crashing when you adding crap loads of constraints to your view

The view your setting constraints to ain't got no parent.

Your naming convention or dictionary is wrong. VFL is a idiot so if you do know specify the dictionary well it crashes. we will get to this

Your constraints are soooo in conflict that you just killed xcode. 

Remember  So-cratz - "The only true wisdom consists in knowing that you know nothing".

... thats US!!!!

Point 1

So point one, if you set constraints to something that has no superview it ain't going to work. When you think about it, it kind of makes sense. Xcode doesn't magically know what this UIlabel is going to be a child of a view. 

Also whenever you are even thinking about using a VFL for views. You have to implement this guy

setTranslatesAutoresizingMaskIntoConstraints

By defualt autoresizing masks on a view uses constraints to determine view's position. So if you are setting constraints on a view manually you have to set that to NO. Then you will have no conflicts with default constraints. 

Try not to use initWithFrame at all, replace that guy with new.

// no no no no UIView * newView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; // yeah yeah yeah UIView * newViewAuto = [UIView new]; [newViewAuto setTranslatesAutoresizingMaskIntoConstraints:NO];

Warning bells might be ringing right now due to no frames being set. Remember that your view will autoresize according to intrinsic content size. Basically it will be as big as whatever you shove in it. Also you are going to set constraints to that view anyways when you add it to its superview. This in turn will set the size of the view.

So if your view had no set widths or heights, but your constraints set its edges to that of the superview. This will stretch the view to fullscreen. 

Point 2

Ok one of the stupidly annoying things about VFL is that its kinda dumb. You are essentially passing it a string with the names of your UIElements. In this string you are telling it padding values, width and height values and whether its aligned vertical or horizontal. THATS IT

So if you see

V|[backgroundBox]|

V is for vertical

If you want to align things up and Down Use a V 

| This means superview

[outletname] You declare references to outlets by shoving them in brackets

So 

V|[backgroundBox]|

Means that a background box is going to be set to edges of superview VERTICALLY, not horizontally. 

OK so you got vertical down, now you want to mess with widths. To do that Use H

H|[backgroundBox]|

So this guy is basically setting the backgroundBox to the edges of the superview's horizontal components

So if you combined the two

H|[backgroundBox]|

V|[backgroundBox]|

That will stretch the background box to the edges of the view, so full screen. Notice here that we did not set the frame values EVER.

Point 3

Ok so point 2 was the basics but pretty useless in real life development. Lets try to use a nicer example, one that you will actually benefit from.

We are doing to make a traffic light

In autolayout it looks like this

UIView * newViewAuto1 = [UIView new]; [newViewAuto1 setBackgroundColor:[UIColor redColor]]; [newViewAuto1 setTranslatesAutoresizingMaskIntoConstraints:NO]; UIView * newViewAuto2 = [UIView new]; [newViewAuto2 setBackgroundColor:[UIColor yellowColor]]; [newViewAuto2 setTranslatesAutoresizingMaskIntoConstraints:NO]; UIView * newViewAuto3 = [UIView new]; [newViewAuto3 setBackgroundColor:[UIColor greenColor]]; [newViewAuto3 setTranslatesAutoresizingMaskIntoConstraints:NO]; [self.view addSubview:newViewAuto1]; [self.view addSubview:newViewAuto2]; [self.view addSubview:newViewAuto3]; NSDictionary * bindings = NSDictionaryOfVariableBindings(newViewAuto1, newViewAuto2,newViewAuto3); [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[newViewAuto1]|" options:0 metrics:nil views:bindings]]; [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[newViewAuto2]|" options:0 metrics:nil views:bindings]]; [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[newViewAuto3]|" options:0 metrics:nil views:bindings]]; [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|[newViewAuto1][newViewAuto2(==newViewAuto1)][newViewAuto3(==newViewAuto1)]|" options:0 metrics:nil views:bindings]];

So what are we doing, well first off we create the three views and set the colours. 

Next we need to create a dictionary which VFL can reference the views. The guys at apple make a nice helper method that does this for us.(although you can also just create a nsdictionary manually and set the key/values yourself)

NSDictionary * bindings = NSDictionaryOfVariableBindings(newViewAuto1, newViewAuto2,newViewAuto3);

This method will make a dictionary with the value name and key set to the name of the outlet. 

So "newViewAuto1"= <newViewAuto1 obj>

This is how VFL references the outlet, So in this line

[self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[newViewAuto1]|"

We are setting the horizontal leading and trailing of newViewAuto to be pinned to the same of the superview. Not that the string references "newViewAuto1", which obviously will be referred in the dictionary. If you get the naming wrong in VFL it will crash so make sure you get the names you reference correct. 

Now lets do the vertical alignment to get them all in a nice row format.

[self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|[newViewAuto1][newViewAuto2(==newViewAuto1)][newViewAuto3(==newViewAuto1)]|" options:0 metrics:nil views:bindings]];

So this is what is going on

Using V so we are aligning everything vertically

We are putting the views next to each other with no padding values. So they will naturally be positioned right next to each other. 

Finally inside the [] brackets we setting a equals constraint. By setting (==newViewAuto1) because its in a vertical constraint, this will basically set the height of the view to be equal the other view. So [newViewAuto2(==newViewAuto1)]. Means newViewAuto2's height will be the same as newViewAuto1's. This is set to newViewAuto3 aswell. This is how we have equal height distribution. 

You can also use other relations such as == ,<= ,>=.

Point 3

Set up constraints slowly and one at a time, try not setting constraints everywhere at once cause it will be a pain to debug. 

Also because you do not have to specify view sizes now because of intrinsic content size. It is good practice to added and set constraints into containers. Then position the container in relation to the whole superview. So in 1 case say you have 4 labels with padding aligned. You can just added them to a container view then position that view central to the super. This will in turn position all the views. 

Hope this helps

Posting video to youtube

So by now you should have integrated the GTL.xcodeproject correctly into your workspace/project. You have also integrated all the youtube header files and GLObject header files. 

In the next section i will try to cover how to actually post to youtube, using google's oauth services. 

So first things first you need to include the CLIENT_ID, CLIENT_SECRET, API_KEY from your google app dashboard. Once you have those import in your header file the following

#import "GTLYouTube.h" #import "GTMOAuth2ViewControllerTouch.h" #import "GTMOAuth2Authentication.h" #import "GTLServiceYouTube.h" #import "GTMHTTPUploadFetcher.h" #import "GTMHTTPFetcherLogging.h" #import "GTLYouTubeConstants.h"

Next up is to create a GRLServiceYoutube object, i would declare it as a property. 

-(GTLServiceYouTube *)youTubeService{ if (!_youTubeService) { _youTubeService = [[GTLServiceYouTube alloc] init]; _youTubeService.shouldFetchNextPages = YES; _youTubeService.retryEnabled = YES; GTMOAuth2Authentication *auth = [GTMOAuth2ViewControllerTouch authForGoogleFromKeychainForName:KEYCHAIN_ITEMNAME clientID:CLIENT_ID clientSecret:CLIENT_SECRET]; [_youTubeService setAuthorizer:auth]; } return _youTubeService; }

Lazy instantiate the object, the youtubeService object uses a GTMOAuth2ViewControllerTouch authorisation object. Once you have authenticated, the authentication client will store a copy of the token in the keychain. It would be a good idea to define a KEYCHAIN string for easier reference.

So next stage is to retrieve a GTMOAuth2ViewControllerTouch, note DO NOT use the GTMOAUTH2Window as the google example shows. The google client ios sample runs for MaxOSX. Fortunetly they have also written a ios Version. Declare one like you would any view controller.

  -(void)presentGoogleAuthenticationControllerForSender:(id)sender { GTMOAuth2ViewControllerTouch *viewController = [[GTMOAuth2ViewControllerTouch alloc] initWithScope:kGTLAuthScopeYouTube clientID:CLIENT_ID clientSecret:CLIENT_SECRET keychainItemName:KEYCHAIN_ITEMNAME delegate:self finishedSelector:@selector(viewController:finishedWithAuth:error:)]; [sender pushViewController:viewController animated:YES]; } - (void)viewController:(GTMOAuth2ViewControllerTouch *)viewController finishedWithAuth:(GTMOAuth2Authentication *)auth error:(NSError *)error { if (self.sender) { [self.sender popToRootViewControllerAnimated:YES]; self.sender = nil; } NSLog(@"%@ auth ", auth.description); NSLog(@"%@ auth Service ", auth.serviceProvider); NSLog(@"%@ authtoken URL ", auth.tokenURL); NSLog(@"%@ auth redirectURI", auth.redirectURI); if (error != nil) { NSLog(@"authoFailed"); } else { NSLog(@"passed"); [self.youTubeService setAuthorizer:auth]; NSLog(@"%@",[self.youTubeService.authorizer description]); } }

When you run the code, xcode will complain that the xib file for GTMOAuth2Autnetication cannot be found. The xib file you need is called GTMOAuth2ViewTouch.xib. Look for it on spotlight and copy and reference it to your project. Now when you call the method about you should be taken to the correct authentication page. Once the user authenticates the completion handler will set the authentication to your youtube service.

To check if your GTMOAuth2Authentication token is still valid you can call canAuthorize. Call this check whenever you wish to perform a upload request. If it returns No, re-authenticate the the user. 

-(GTLYouTubeVideoStatus *)statusForPrivary:(NSString *)privacySetting{ GTLYouTubeVideoStatus *status = [GTLYouTubeVideoStatus object]; status.privacyStatus = privacySetting; return status; } -(GTLYouTubeVideoSnippet *)videoSnippetforTitle:(NSString *)title withDescription:(NSString*)description{ GTLYouTubeVideoSnippet *snippet = [GTLYouTubeVideoSnippet object]; [snippet setTitle:title]; [snippet setDescriptionProperty:description]; return snippet; } -(void)UploadVideo:(NSData *)videoData WithTitle:(NSString *)title withDescription:(NSString *)desc{ [GTMHTTPFetcher setLoggingEnabled:YES]; GTLYouTubeVideo *video = [GTLYouTubeVideo object]; video.status = [self statusForPrivary:@"unlisted"]; video.snippet = [self videoSnippetforTitle:title withDescription:desc]; if (videoData) { GTLUploadParameters *uploadParameters = [GTLUploadParameters uploadParametersWithData:videoData MIMEType:@"video/quicktime"]; GTLQueryYouTube *query = [GTLQueryYouTube queryForVideosInsertWithObject:video part:@"snippet,status" uploadParameters:uploadParameters]; [self.youTubeService executeQuery:query completionHandler:^(GTLServiceTicket *ticket, id object, NSError *error) { if (!error) { NSDictionary * returnedJSON = ticket.fetchedObject.JSON; NSLog(@"%@", [returnedJSON description]); } else{ NSLog(@"%@ fail", [error localizedDescription]); } }]; } }

To upload your video you need to create a GTLYoutubeVideoStatus Object which determines the privacy settings for your video. You can set your video to be public, private or unlisted. Unlisted makes your video unvisibile on normal youtube feeds but public users can watch the video if they have the direct URL. You also need to create a GTLYoutubeVideo Snippet which contains meta data for the video. i.e title and description. 

-(void)UploadVideo:(NSData *)videoData WithTitle:(NSString *)title withDescription:(NSString *)desc

creates these objects for you but if you want to change anything feel free. You need to pass in the video itself in the form of nsdata. My application was referencing the photogallery so the mimeType for my video uploads would be quicktime. Feel free to change these too.  You can set the mimetype in GTLUploadParamaters. After that we create a Query object and set the part to be snippet,status. We are uploading a video to youtube therefore we are using the queryVideosInsertWithObject method.

Once the query has been created we execute it using the execute method from out youtubeService property. Using the completion handler you can perform your own success or failure logic. 

If the request is a success you should be returned a ticket JSON object. Inside the json will contain various metadata about your video. Including the unique Youtube ID. If you append this id to the following url www.youtube.com/watch?v=

You will be redirect to your video. 

Anyway i hope that was helpful. 

ERRORS

Anyone using the client code and having access errors, make sure you are setting your service on the correct scope. When you define a GTMOAuth2ViewControllerTouch object it asks for a scope. If you look at 

GTLYouTubeConstants.h

You can see various base urls pre defined for you. MAKE SURE it is set to kGTLAUTHSCOPEYOUTUBLE

If you are still experiencing these errors you should check your google console and make sure the youtube apis are set to on. Also in my experience it takes around 30 minutes for it to become activated. So if your request is going through but you are getting errors. Walk away for 30 minutes. Go grab a coffee, pastry, reflect on your life, hassle a work mate. When you come back you never know it might work.

I hope this has been helpful to you. Next time i will be posting a tutorial about yammer integration
