Copy an pasted from Apples Bubble Level source code.

This is the line you want

UIImage *newImage = [image stretchableImageWithLeftCapWidth:10 topCapHeight:10];

full code here

- (UIButton *)buttonWithTitle:(NSString *)title target:(id)target selector:(SEL)inSelector frame:(CGRect)frame image:(UIImage*)image {
    UIButton *button = [[UIButton alloc] initWithFrame:frame];
    button.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
    button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
    [button setTitle:title forState:UIControlStateNormal & UIControlStateHighlighted & UIControlStateSelected];
    [button setTitleColor:[UIColor blackColor] forState:UIControlEventTouchDown];
    UIImage *newImage = [image stretchableImageWithLeftCapWidth:10 topCapHeight:10];
    [button setBackgroundImage:newImage forState:UIControlStateNormal];
    [button addTarget:target action:inSelector forControlEvents:UIControlEventTouchUpInside];
    button.adjustsImageWhenDisabled = YES;
    button.adjustsImageWhenHighlighted = YES;
    [button setBackgroundColor:[UIColor clearColor]];   // in case the parent view draws with a custom color or gradient, use a transparent color
    [button autorelease];
    return button;
}
