这种方法创建的简单明了对位置的改动容易，点击后的高亮状态可以参考，获取uiimage纯色图片，然后调用- (void)setImage:(UIImage *)image forState:(UIControlState)state;就可以改动点击后颜色（背景颜色），效果还是不错的

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();    CGColorRef colorref = CGColorCreate(colorSpace,(CGFloat[]){ 1, 0, 0, 1 });    [self.layer setMasksToBounds:YES];    [self.layer setCornerRadius:10.0]; //设置矩形四个圆角半径    [self.layer setBorderWidth:1]; //边框宽度    [self.layer setBorderColor:colorref];//边框颜色    UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, (self.frame.size.height/2-image.size.height/6), image.size.width/3, image.size.height/3)];    imageView.image = image;    imageView.userInteractionEnabled = YES;    UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(image.size.width/3+20, self.frame.size.height/2-20, self.frame.size.width-image.size.width/3-20, 40)];    titleLabel.textColor = [UIColor whiteColor];    titleLabel.font = [UIFont fontWithName: @"Helvetica-Bold" size : 17.0 ];    titleLabel.text = title;        [self addSubview:titleLabel];        [self addSubview:imageView];}

　　属性：　imageEdgeInsets
　　　　　　contentEdgeInsets

UIEdgeInsetsMake
Creates an edge inset for a button or view.

UIEdgeInsets UIEdgeInsetsMake (
CGFloat top, //距离上方
CGFloat left, //距离左边
CGFloat bottom, 、//距离下方
CGFloat right //距离右方
);

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];//button的类型      button.frame = CGRectMake(100, 100,90, 90);//button的frame     button.backgroundColor = [UIColor cyanColor];//button的背景颜色    //    在UIButton中有三个对EdgeInsets的设置：ContentEdgeInsets、titleEdgeInsets、imageEdgeInsets      [button setImage:[UIImage imageNamed:@"IconHome@2x.png"] forState:UIControlStateNormal];//给button添加image      button.imageEdgeInsets = UIEdgeInsetsMake(5,13,21,button.titleLabel.bounds.size.width);//设置image在button上的位置（上top，左left，下bottom，右right）这里可以写负值，对上写－5，那么image就象上移动5个像素      [button setTitle:@"首页" forState:UIControlStateNormal];//设置button的title      button.titleEdgeInsets = UIEdgeInsetsMake(71, -button.titleLabel.bounds.size.width-50, 0, 0);//设置title在button上的位置（上top，左left，下bottom，右right）   //   button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
