Add rounded corners to all UIImageViews
code-reuse, ios, objective-c-category, subclass
Solution
You could use a category for UIImage which is an alternate way to subclass a Class and sometimes easier for just small changes.
e.g add a method that returns a UIImage with the rounded corner attributes set.
+(UIImage *)imageWithContentsOfFile:(NSString *)file cornerRadius:(NSInteger)...

Problem
I would like to add some rounded corners to all of the UIImageViews in my project. I have already got the code working, but am having to apply it to every image; should I subclass UIImageView to add this? If so, can someone give me some pointers as to how to do this? Here is the code ``` - (void)viewDidLoad { [super viewDidLoad]; NSString *mainpath = [[NSBundle mainBundle] bundlePath]; welcomeImageView.image = [UIImage imageWithContentsOfFile:[mainpath stringByAppendingString:@"/test.png"]]; welcomeImageView.layer.cornerRadius = 9.0; welcomeImageView.layer.masksToBounds = YES; welcomeImageView.layer.borderColor = [UIColor blackColor].CGColor; welcomeImageView.layer.borderWidth = 3.0; CGRect frame = welcomeImageView.frame; frame.size.width = 100; frame.size.height = 100; welcomeImageView.frame = frame; } ```
