iphone - Crop UIImage to fit a frame image

Question

I need to crop a UIImage, taken with the device camera, so that it fits inside another UIImage, which represents a frame (with rounded borders and so on). Check the image below:

Using Aspect Fill

Using Aspect Fit

So, what I need is to remove the image excess that is out of the frame bounds. I tried using UIBezierPath, CGImageRef and other methods that I Googled but I'm not finding a solution for this.

Answer 1

In Interface Builder, use the following configuration:

There are two important settings, namely:

1. Mode: Aspect Fill

2. Clip Subviews

It can also be done programmatically:

[imageView setContentMode:UIViewContentModeScaleAspectFill];
[imageView setClipsToBounds:YES];

This will correctly fill the view with the image, keep its aspect ratio and hide what doesn't fit.
