I am new to iOS development and also to GitHub so apologies if I am doing all this wrong.
Thank you. I found this project very helpful.

iOS6 / Depreciation Warnings
Just wanted to point out a couple of minor changes that I needed for iOS 6 because of depreciation warnings:

Inside method __createWithText in file WToast.m

// UITextAlignmentCenter depreciated
textLabel.textAlignment = NSTextAlignmentCenter;                   

// UILineBreakModeWordWrap depreciated
textLabel.lineBreakMode = NSLineBreakByWordWrapping;    

Tapping a toast performing an action
I also wanted to share a useful addition: performing an action when a toast is tapped

In file WToast.h I declared in the interface block:

     +(void)tappedToast:(UIGestureRecognizer*)recognizer;

And in file WToast.m I implemented:

     +(void)tappedToast:(UIGestureRecognizer*)recognizer
     {
         // Only respond if we're in the ended state (similar to touchupinside)
         if( [recognizer state] == UIGestureRecognizerStateEnded )
         {
             // the label that was tapped
             //UILabel* label = (UILabel*)[recognizer view];

             // DO SOMETHING HERE
         }
     }

Finally I added the following code to your methods __createWithText and __createWithImage to link the tappedToast method to the tap gesture.

     UITapGestureRecognizer* tap = 
              [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(**tappedToast**:)];

     [toast setUserInteractionEnabled:YES];
     [toast addGestureRecognizer:tap];

Hope this is helpful to someone.
