button的属性Image占用 用往button上添加了一个, 移除时候tag值找还蛮方便

-(void)removeImage:(UIButton *)view{

    for (UIImageView *imagein view.subviews) {

        if (image.tag ==77777) {

            [image removeFromSuperview];

        }

    }

}

-(void)addImage:(UIButton *)view

{    CGFloat width = view.frame.size.width;

    self.imageV = [[UIImageViewalloc] initWithFrame:CGRectMake(width -25, 10, 15, 15)];

    self.imageV.tag =77777;

    self.imageV.image = [UIImageimageNamed:@"icon_ok15x15.5"];

    [view addSubview:self.imageV];

}
