There are plenty of threads about aligning a button image according to the title text, but I can\'t find anything about just aligning the image to the right side of the butt
This worked for me by setting:
button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentRight;
Then for the inner image I set the right inset to 0.
button.imageEdgeInsets = UIEdgeInsetsMake(10.0, 10.0, 10.0, 0);
