问题


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);
}

And then I add the image with this code:

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

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

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

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

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

I have this:

I want get it:

How could I change the color of the imageButton?


回答1:


We can apply the desired color for the transparent icons with the following way.

1.Drag the image on Assets.xcassets and In asset attribute inspector change the Render as attribute to Template Image.

2.And set the required tint color like below way.

icon.tintColor = [UIColor redColor];

Hope it will help you.

The solution to change tintColor property was setImage with renderingMode:

 imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate

With this code:

[self.myButton setImage:[[UIImage imageNamed:@"myImageButton.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate] forState:UIControlStateNormal];

Then set image to button with this code we can set the tintColor property correctly:

 self.myButton.tintColor = [UIColor redColor];

Change the UIButtonType to UIButtonTypeCustom in Interface Builder or programmatically with

 UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom]; 

Change the attributes on your own and recreate the rounded corners

myButton.backgroundColor = [UIColor redColor];
myButton.layer.borderColor = [UIColor blackColor].CGColor;
myButton.layer.borderWidth = 0.5f;
myButton.layer.cornerRadius = 10.0f;

let me know the status ..

Create a layer and set your desired coloured and mask in on your ImageView in your button like this.

for (UIView *view in myButton.subviews) {
        if ([view isKindOfClass:[UIImageView class]]) {
            CALayer *mask = [CALayer layer];
            mask.backgroundColor = [UIColor redColor].CGColor;
            view.layer.mask = mask;
        }
    }

Swift 4 and 4.2

let img = UIImage.init(named: "buttonName")?.withRenderingMode(UIImageRenderingMode.alwaysTemplate)
            btn.setImage(img, for: .normal)
            btn.tintColor = .gray

}
