默认情况下，不设置的效果，都使居中现实，button为150＊150
使用以下设置后：
[self setTitleEdgeInsets:UIEdgeInsetsMake( 0.0,-backGroundImag.size.width, 0.0,0.0)];
[self setImageEdgeInsets:UIEdgeInsetsMake(0.0, 0.0,0.0, -self.titleLabel.bounds.size.width)];
若要title在图片的上方，则位置相对于图片来说，向上移动－80
[self setTitleEdgeInsets:UIEdgeInsetsMake( -80.0,-backGroundImag.size.width, 0.0,0.0)];
[self setImageEdgeInsets:UIEdgeInsetsMake(0.0, 0.0,0.0, -self.titleLabel.bounds.size.width)];
效果如下：
综上所述，若单独设置一个title或者image在button中的位置，UIEdgeInsets是相对于button的frame来计算的（上，左，下，右，），如果是刚才所描述的情况，则title是相对于image的frame设置的，而image的位置是相对于titel的位置设置的
over！

实例源码：
UIImage * image = [[UIImage imageNamed:@"telIcon"] retain];
NSLog(@"%@>>",NSStringFromCGSize(image.size));
UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setBackgroundColor:[UIColor yellowColor]];
[button setFrame:CGRectMake(80, 80, 150, 150)];
[button setTitle:@"测试位置" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button.titleLabel setFont:[UIFont boldSystemFontOfSize:10.0]];
[button setTitleEdgeInsets:UIEdgeInsetsMake(0.0, -image.size.width, 0.0, 0.0)];
[button setImageEdgeInsets:UIEdgeInsetsMake(15.0, 0.0, 0.0, -button.titleLabel.bounds.size.width)];
NSLog(@"%@",NSStringFromUIEdgeInsets(button.titleEdgeInsets));
[button setImage:image forState:UIControlStateNormal];
[self.view addSubview:button];
UIButton上使用UIEdgeInsetsMake让title跟图片对齐
