iPhone UIButton - image position

Set the imageEdgeInset and titleEdgeInset to move the components around within your image. You could also create a button using those graphics that is full size, and use that as the background image for the button (then use titleEdgeInsets to move the title around).

My solution to this is quite simple

[button sizeToFit];
button.titleEdgeInsets = UIEdgeInsetsMake(0, -button.imageView.frame.size.width, 0, button.imageView.frame.size.width);
button.imageEdgeInsets = UIEdgeInsetsMake(0, button.titleLabel.frame.size.width, 0, -button.titleLabel.frame.size.width);

Raymond W's answer is best here. Subclass UIButton with custom layoutSubviews. Extremely simple to do, here's a layoutSubviews implementation that worked for me:

- (void)layoutSubviews
{
    // Allow default layout, then adjust image and label positions
    [super layoutSubviews];

    UIImageView *imageView = [self imageView];
    UILabel *label = [self titleLabel];

    CGRect imageFrame = imageView.frame;
    CGRect labelFrame = label.frame;

    labelFrame.origin.x = imageFrame.origin.x;
    imageFrame.origin.x = labelFrame.origin.x + CGRectGetWidth(labelFrame);

    imageView.frame = imageFrame;
    label.frame = labelFrame;
}

On iOS 9 onwards, seems that a simple way to achieve this is to force the semantic of the view.

Or programmatically, using:

button.semanticContentAttribute = .ForceRightToLeft
