Resizing UIImageView inside UITableViewCell
in my application, the size UITableViewCell
is dynamic, which means each has its own height. inside each cell there is a background image in UIImageView
. Through the storyboard, I used autolayouts
to adjust UIImageView
to automatically stretch as the cell stretches. The problem is that when they stretch the whole image, it gets stretched at the corners. So I looked online and I came up with resizableImageWithCapInsets: to stretch the stretchable sides and exclude unwanted ones. So I tried the following code in tableView: cellForRowAtIndexPath: as I only need the image to stretch vertically (height):
[cell.backgroundImage.image resizableImageWithCapInsets:UIEdgeInsetsMake(16, 0, 16, 0)];
however the problem continued like below picture
As you can see, the corners of the image are still stretched. What am I doing wrong? incorrect edgeInset values? or should I put the code somewhere else?

You create UIEdgeInsets values using the UIEdgeInsetsMake () function. UIEdgeInsets encapsulates four different CGFloat values for nested values top, bottom, left, and right
individually. Positive insertion values shrink the content area, while negative insertion values will effectively enlarge it. Make sure you create the image first and apply the insets there, and then once that's done, apply the image to the backgroundView instead of trying to edit the edge inserts from the backgroundView.image property.
UIImageView *cellBGIV =
[[UIImageView alloc] initWithImage:[[UIImage imageNamed:@"imageName"]
resizableImageWithCapInsets:UIEdgeInsetsMake(5.0, 5.0, 5.0, 5.0)]];
cell.backgroundView = cellBGIV;
