Converting 'Bearded' for iOS 7?

Hi Guys,

Trying to get 'Bearded' to work on iOS 7, it doesn't work badly on a 3.5", but on a 4" display its all stretched and distorted. I don't suppose anyone has any ideas?

Bearded is the tutorial here: http://blog.teamtreehouse.com/creating-a-iphone-app-bearded-part2

Hm, I haven't mucked around with this app yet, but the obvious question is--did you add the code at the bottom for handling the iPhone 5 screen? I'm not sure exactly how iOS 7 would change things (well, I might have some idea), but even if so, I'm not sure if we can talk about it here yet. Has the iOS 7 NDA been lifted?

Hi Nathan, thanks for replying! Sure have, and it loads the 568@2x wallpaper fine - and it can even output an undistorted image, however the image that you import needs to be the exact 1136x640 resolution, anything over or under and the beard warps. I believe the code that needs tweaking is this:

- (UIImage *) blendImages {
UIImage *photoImage = self.photoView.image ;
UIImage *beardImage = self.beardView.image;

// Get the size of the photo
CGSize photoSize = CGSizeMake(photoImage.size.width, photoImage.size.height);

// Create a bitmap graphics context of the photoSize
UIGraphicsBeginImageContext( photoSize );

// Draw the photo in the specified rectangle area
[photoImage drawInRect:CGRectMake(0,0,photoSize.width,photoSize.height)];

CGPoint origin = self.beardView.frame.origin;
CGSize size = self.beardView.frame.size;

CGFloat xScale = photoImage.size.width / self.view.bounds.size.width;
CGFloat yScale = photoImage.size.height / (self.view.bounds.size.height-44);

// Draw the beard in the specified rectangle area
[beardImage drawInRect:CGRectMake((origin.x * xScale), (origin.y * yScale),
                                   size.width * xScale, size.height * yScale)
              blendMode:kCGBlendModeNormal alpha:1.0];


// Save the generated image to an image object
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

return newImage;

}

I'm just going to try adding a crop method in...that might solve it?

I'm playing with it now as well. I'll let everyone know if I figure something out. Go ahead and report back when you can, Thomas!

No luck here unfortunately, I was able to implement a custom Crop method but it was causing far too much user input for something that worked fine in iOS6...

Getting some slightly better results now I'm playing around with different scales - if anyone has any input that would be awesome :) 

- (UIImage *) blendImages {
UIImage *photoImage = self.photoView.image ;
UIImage *beardImage = self.beardView.image;
UIImage *hairImage = self.hairView.image;

CGSize photoSize = CGSizeMake(photoImage.size.width, photoImage.size.height);

CGRect screenBounds = [[UIScreen mainScreen] bounds];
CGFloat screenScale = [[UIScreen mainScreen] scale];

CGSize screenSize = CGSizeMake(screenBounds.size.width * screenScale, screenBounds.size.height * screenScale);

UIGraphicsBeginImageContext( photoSize );

[photoImage drawInRect:CGRectMake(0,0,photoSize.width,photoSize.height)];



CGPoint origin = self.beardView.frame.origin;
CGSize size = self.beardView.frame.size;

CGPoint originHair = self.hairView.frame.origin;
CGSize sizeHair = self.hairView.frame.size;

CGFloat xScale = screenSize.width / self.view.bounds.size.width;
CGFloat yScale = screenSize.height / (self.view.bounds.size.height);

CGFloat x1Scale = photoSize.width / self.view.bounds.size.width;
CGFloat y1Scale = photoSize.height / (self.view.bounds.size.height);

[beardImage drawInRect:CGRectMake((origin.x * x1Scale), (origin.y * y1Scale),
                                  size.width * xScale, size.height * yScale)
             blendMode:kCGBlendModeNormal alpha:1.0];

[hairImage drawInRect:CGRectMake((originHair.x * x1Scale), (originHair.y * y1Scale),
                                 sizeHair.width * xScale, sizeHair.height * yScale)
            blendMode:kCGBlendModeNormal alpha:1.0];


UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

return newImage;

}
