初始图片尺寸大小为 25 * 28 pixels
现在我们在根试图上创建两个button
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(50, 100, 25, 28);
[button setBackgroundImage:[UIImage imageNamed:@"btn.png"] forState:UIControlStateNormal];
[self.view addSubview:button];
UIButton *button1 = [UIButton buttonWithType:UIButtonTypeCustom];
button1.frame = CGRectMake(50, 200, 200, 28);
UIImage *image = [UIImage imageNamed:@"btn.png"];
[button1 setBackgroundImage:image forState:UIControlStateNormal];
[self.view addSubview:button1];
