How to change tintColor of image in UIButton with imageEdgeInsets?(如何使用 imageEdgeInsets 更改 UIButton 中图像的 tintColor?)

问题描述

我的 Objective-c 应用程序中有一个 UIButton.我的按钮已修改，添加了如下文本和图像:

I I have an UIButton in my objective-c application. My button was modified adding text and image like:

- (void)centerButtonAndImageWithSpacing:(CGFloat)spacing {
     CGFloat insetAmount = spacing / 2.0;
     self.imageEdgeInsets = UIEdgeInsetsMake(0, -insetAmount, 0, insetAmount);
     self.titleEdgeInsets = UIEdgeInsetsMake(0, insetAmount, 0, -insetAmount);
     self.contentEdgeInsets = UIEdgeInsetsMake(0, insetAmount, 0, insetAmount);
}

然后我用这段代码添加图像:

And then I add the image with this code:

[self.myButton setImage:[UIImage imageNamed:@"imageButton.png"] forState:UIControlStateNormal];

我想更改图像的 tintColor，但是当我尝试更改时，我的代码不起作用:

I want change the tintColor of the image, but when I try change this, my code isn't work:

[self.myButton setTintColor:[UIColor redColor]];

我正在尝试使用此代码，但没有成功:

I'm trying use this code, but didn't work:

UIImage* img = [UIImage imageNamed:imageName];
icon.image = [img imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
icon.tintColor = [UIColor redColor];

我有这个:
