如何用imageEdgeInsets更改UIButton中图像的tintColor？ [英] How to change tintColor of image in UIButton with imageEdgeInsets?

问题描述

我在Objective-c应用程序中有一个UIButton。我的按钮被修改为添加文本和图像，如：

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片：

And then I add the image with this code:

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

我想更改图片的tintColor，但是当我尝试更改它时，我的代码不是work：
