UIButton Padding

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.

Well actually, there is one stupidly simplistic way to expand the width of UIButtons if you don't want to mess with subclassing.... try this:

[b setTitle:[NSString stringWithFormat:@"  %@  ", @"Title"] forState:UIControlStateNormal];

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

No, there's nothing like CSS or style sheets for iOS, if you want to resize a button you'll have to do it manually setting the frame.

In order to automatize this task, you can create a button and subclass it, or use categories.
