The scaleAspectFit and scaleAspectFill modes scale the image to fit or fill the space while maintaining the image's original aspect ratio. Similarly, any further transparency in the background of the image is dependent on the transparency of the image view and the transparency of the UIImage object it displays. When the

27 Oct 2016 We mostly use three types of Content Mode property. These are: Scale To Fill; Aspect Fit; Aspect Fill. While using UIImageView in iOS we should use appropriate content mode to show the image. How these Content Mode render the image we can see by following examples. UIImage of size (100?150)
19 Mar 2013 (UIImage*)setProfileImage:(UIImage *)imageToResize onImageView:(UIImageView *)imageView { CGFloat width = imageToResize.size.width; CGFloat height = imageToResize.size.height; float scaleFactor; if(width > height) { scaleFactor = imageView.frame.size.height / height; } else { scaleFactor
13 Jan 2012 The math for that is a little bit hairy, but fortunately, here's a solution I prepared earlier: - (UIImage *)imageScaledToSize:(CGSize)size { //create drawing context UIGraphicsBeginImageContextWithOptions(size, NO, 0.0f); //draw [self drawInRect:CGRectMake(0.0f, 0.0f, size.width, size.height)]; //capture
23 Sep 2015 contentMode = UIViewContentModeScaleAspectFill //width < height we fill it until width is taken up and clipped on top/bottom }. UIViewContentModeScaleAspectFit. Scales the content to fit the size of the view by maintaining the aspect ratio. Any remaining area of the view's bounds is transparent.

12 Oct 2009 Another contributing factor is that the iPhone API is still relatively immature, and developers too often require custom code to fill in its gaps. platforms, but on the iPhone, it's only a matter of instantiating a UIImage , passing it to a UIImageView of the appropriate size, and setting the cornerRadius property.
