在UIImageView上使用Tint颜色 [英] Using Tint color on UIImageView

问题描述
我有自己的 UIButton
的子类。我在其上添加 UIImageView
并添加图片。我想用色调在图像上画它但不起作用。
I have my own subclass of UIButton
. I add UIImageView
on it and add image. I would like to paint it over the image with tint color but it doesn't work.
到目前为止我有:
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
self.backgroundColor = [UIColor clearColor];
self.clipsToBounds = YES;
self.circleView = [[UIView alloc]init];
self.circleView.backgroundColor = [UIColor whiteColor];
self.circleView.layer.borderColor = [[Color getGraySeparatorColor]CGColor];
self.circleView.layer.borderWidth = 1;
self.circleView.userInteractionEnabled = NO;
self.circleView.translatesAutoresizingMaskIntoConstraints = NO;
[self addSubview:self.circleView];
self.iconView = [[UIImageView alloc]init];
[self.iconView setContentMode:UIViewContentModeScaleAspectFit];
UIImage * image = [UIImage imageNamed:@"more"];
[image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
self.iconView.image = image;
self.iconView.translatesAutoresizingMaskIntoConstraints = NO;
[self.circleView addSubview:self.iconView];
...
和选择:
- (void) setSelected:(BOOL)selected
{
if (selected) {
[self.iconView setTintColor:[UIColor redColor]];
[self.circleView setTintColor:[UIColor redColor]];
}
else{
[self.iconView setTintColor:[UIColor blueColor]];
[self.circleView setTintColor:[UIColor blueColor]];
}
}
我做错了什么? (图像的颜色始终保持原样相同)
What I did wrong? (color of image stays always the same-as it was original)
推荐答案
而不是此代码:
[image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
你应该:
image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
在 Swift 4.1
image = UIImage(named: "name")!.withRenderingMode(.alwaysTemplate)
