Make rounded image with storyboards - objective-c

Question

I want to make rounded photo from Facebook, but image always scales.
So i have Storyboard with next parameters:
http://prntscr.com/5bpuqy
align center X, align center Y, width equals 72, height equals 72.
I understand, that problem may be in 72/72, but image mode in storyboard is "Aspect Fit"
I call my methods for downloading image by URL and then make it cornered with radius.
// call
[UIImage setRoundImageView:self.p_photo WithURL:[p_user fullURL] withCornerSize:37];
+ (void)setRoundImageView:(UIImageView *)imageView WithURL:(NSURL *)url withCornerSize:(CGFloat)corner
{
dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){
[[SDWebImageManager sharedManager] downloadImageWithURL:url
options:0
progress:^(NSInteger receivedSize, NSInteger expectedSize) {
} completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, BOOL finished, NSURL *imageURL) {
if (image && finished)
{
[self setRoundImage:image forImageView:imageView withCornerSize:corner];
}
}];
});
}
+ (void)setRoundImage:(UIImage *)image forImageView:(UIImageView *)imageView withCornerSize:(CGFloat)corner
{
dispatch_async(dispatch_get_main_queue(), ^{
UIGraphicsBeginImageContextWithOptions(imageView.bounds.size, NO, [UIScreen mainScreen].scale);
[[UIBezierPath bezierPathWithRoundedRect:imageView.bounds
cornerRadius:corner] addClip];
[image drawInRect:imageView.bounds];
imageView.image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
});
}

Your code is way more complex than it needs to be. You are manually drawing the image into the image view and that is causing the problem. Try this instead:
+ (void)setRoundImageView:(UIImageView *)imageView WithURL:(NSURL *)url
{
// you don't need to wrap this in a dispatch queue, SDWebImageManager takes care of that for you.
[[SDWebImageManager sharedManager] downloadImageWithURL:url options:0 progress:^(NSInteger receivedSize, NSInteger expectedSize) {
} completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, BOOL finished, NSURL *imageURL) {
if (image && finished) {
[self setRoundImage:image forImageView:imageView];
}
}];
}
+ (void)setRoundImage:(UIImage *)image forImageView:(UIImageView *)imageView
{
// you don't need to wrap this in a dispatch queue, it will be called on the main thread.
// you don't need to manually draw the image into the image view. Just add the image to the image view and let it do its thing.
imageView.layer.cornerRadius = CGRectGetHeight(imageView.bounds) / 2;
imageView.layer.masksToBounds = YES;
[imageView setImage:image];
}
And make sure the image view is set to "Aspect Fill" mode in the storyboard.
