UIButton Padding

ios, objective-c, uibutton

Solution

I don't think there's an easier way than what you did. But we can make your code better by moving the method to a UIButton category.

UIButton+Resize.h

@interface UIButton (Resize)

- (void)adjustToSize:(CGSize)size;

@end

UIButton+Resize.m

@implementation UIButton (Resize)

- (void)adjustToSize:(CGSize)size
{
    CGRect previousFrame = self.frame;
    CGRect newFrame = self.frame;
    newFrame.size = size;
    CGFloat adjustX = (size.width - previousFrame.size.width)/2;
    CGFloat adjustY = (size.height - previousFrame.size.height)/2;
    newFrame.origin.x = previousFrame.origin.x - adjustX;
    newFrame.origin.y = previousFrame.origin.y - adjustY;
    self.frame = newFrame;

    UIEdgeInsets edgeInsets = UIEdgeInsetsMake(adjustY, adjustX, adjustY, adjustX);
    self.contentEdgeInsets = edgeInsets;
}

@end

Problem

Is there an equivalent padding for UIButton, just like in CSS?. I seem to have a problem with small buttons so I want to expand the button size for it to be easily clickable. I made a work around code to resize a UIButton and have the contents remain as they are supposed to be: ``` - (void)adjustButtonView:(UIButton *)button toSize:(CGSize)size { CGRect previousFrame = button.frame; CGRect newFrame = button.frame; newFrame.size = size; CGFloat adjustX = (size.width - previousFrame.size.width)/2; CGFloat adjustY = (size.height - previousFrame.size.height)/2; newFrame.origin.x = previousFrame.origin.x - adjustX; newFrame.origin.y = previousFrame.origin.y - adjustY; button.frame = newFrame; UIEdgeInsets edgeInsets = UIEdgeInsetsMake(adjustY, adjustX, adjustY, adjustX); button.contentEdgeInsets = edgeInsets; } ``` I'm just wondering if there is an easier way to expand the UIButtons.
