UIButton的ImageView的tintColor没有改变

Question

如何改变tintColor的button.imageView.如果我使用UIImageView与下面相同的渲染模式使用相同的图像,tintColor则会改变,但按钮的图像视图不会发生相同的情况.是因为buttonType吗？

    UIButton *frontButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [frontButton setImage:[[UIImage imageNamed:FRONT_IMAGE] imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate] forState:UIControlStateNormal];
    [frontButton.imageView setTintColor:[UIColor redColor]];
    [self addSubview:frontButton];

Answer 1

设置按钮类型"系统",然后设置色调颜色.这个解决方案一定会奏效.请试试这个

UIButton *btn = [UIButton buttonWithType:UIButtonTypeSystem];
 [btn setTintColor:YOUR_COLOR];
 [btn setImage:YOUR_Image];
