UIButton ImageView showing only a color fill - ios

Question

I am setting a UIButton's ImageView.Image property to an image that was captured from an ImagePickerController. In my app, the image is captured and rounded with a border. The image is saved and I am loading the image into the button. Problem is, the button is showing only a blue circle and not the image inside... This only seems to happen on buttons.
Here is my code to round the image and set the border:
-(UIImage *)makeRoundedImage:(UIImage *) image
radius: (float) radius;
{
CALayer *imageLayer = [CALayer layer];
imageLayer.frame = CGRectMake(0, 0, image.size.width, image.size.height);
imageLayer.contents = (id) image.CGImage;
imageLayer.backgroundColor = [[UIColor clearColor] CGColor];
imageLayer.masksToBounds = YES;
imageLayer.cornerRadius = radius;
imageLayer.borderWidth = 40;
UIColor *ios7BlueColor = [UIColor colorWithRed:0.0 green:122.0/255.0 blue:1.0 alpha:1.0];
imageLayer.borderColor = ios7BlueColor.CGColor;
UIGraphicsBeginImageContext(image.size);
[imageLayer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *roundedImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return roundedImage;
}
And here is how I am setting the button image:(player.playerImage is a cordite string with the path to the saved image)
-(void)ViewController:(UIViewController *)sender didUpdatePlayerImage:(NSString *)playerImagePath
{
player.playerImage = playerImagePath;
[_editImageButton setImage:[UIImage imageWithContentsOfFile:player.playerImage] forState:UIControlStateNormal];
}
Is this a limitation to the UIButton's ImageView implementation or am I missing something?

Answer 1

You are not actually writing the original image into the context.
Try the following:
UIGraphicsBeginImageContext(image.size);
[image drawInRect:CGRectMake(0, 0, image.size.width, image.size.height)];
[imageLayer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *roundedImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
That should render the image into the context, followed by your layer.
