Change Color of Png in Buttons - iOS

Change color of png in buttons - ios

Following code will set tint colour for normal state of button:

For Swift 4 and newer:

let origImage = UIImage(named: "imageName")
let tintedImage = origImage?.withRenderingMode(.alwaysTemplate)
btn.setImage(tintedImage, for: .normal)
btn.tintColor = .red

You can change tint colour according to your need when state changes for button.

Older versions

For Swift 3:

let origImage = UIImage(named: "imageName")
let tintedImage = origImage?.withRenderingMode(.alwaysTemplate)
btn.setImage(tintedImage, forState: .normal)
btn.tintColor = .redColor

For Swift 2:

Color Tint UIButton Image

As of iOS 7, there is a new method on UIImage to specify the rendering mode. Using the rendering mode UIImageRenderingModeAlwaysTemplate will allow the image color to be controlled by the button's tint color.

Objective-C

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *image = [[UIImage imageNamed:@"image_name"] imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
[button setImage:image forState:UIControlStateNormal]; 
button.tintColor = [UIColor redColor];

Swift

let button = UIButton(type: .custom)
let image = UIImage(named: "image_name")?.withRenderingMode(.alwaysTemplate)
button.setImage(image, for: .normal)
button.tintColor = UIColor.red

Changing color of image embedded to a button (Swift3)

Here's a simpler way to do this without any extension and without resetting the color on touch:

let stencil = myImage.withRenderingMode(.alwaysTemplate) // use your UIImage here
myButton.setImage(stencil, for: .normal) // assign it to your UIButton
myButton.tintColor = UIColor.white // set a color

SwiftUI - Unable to change color of Image icon

I'm not sure what are you trying to to achieve, but probably you just need template rendering mode, like

Image(self.icon)
    .renderingMode(.template)
    .foregroundColor(.white)

How can I change image tintColor in iOS and WatchKit

iOS
For an iOS app, in Swift 3, 4 or 5:

theImageView.image = theImageView.image?.withRenderingMode(.alwaysTemplate)
theImageView.tintColor = UIColor.red

For Swift 2:

theImageView.image = theImageView.image?.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
theImageView.tintColor = UIColor.redColor()

Meanwhile, the modern Objective-C solution is:

theImageView.image = [theImageView.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
[theImageView setTintColor:[UIColor redColor]];

Watchkit
In WatchKit for Apple Watch apps, you can set the tint color for a template image.

1. You must add your image to an Asset Catalog in your WatchKit App, and set the image set to be rendered as a Template Image in the Attributes Inspector. Unlike for an iPhone app, you cannot set the template rendering in code in the WatchKit Extension at present.
2. Set that image to be used in your WKInterfaceImage in interface builder for your app
3. Create an IBOutlet in your WKInterfaceController for the WKInterfaceImage called 'theImage'...

To then set the tint color in Swift 3 or 4:

theImage.setTintColor(UIColor.red)

Swift 2:

theImage.setTintColor(UIColor.redColor())

To then set the tint color in Objective-C:

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

If you use a template image and do not apply a tint colour, the Global Tint for your WatchKit app will be applied. If you have not set a Global Tint, theImage will be tinted light blue by default when used as a template image.

Change image color when click on button

You have a lot of different possibilities here:

1) Indeed make a new image with another color. Fast to start with, but not very flexible.

2) It looks a lot like a vector graphics icon. You could draw the whole icon with Bezier curves, then you can color it any color you want. There are also tools that will generate the code for you (eg PaintCode).

3) There probably is some filter for it you can use (see here: https://developer.apple.com/library/prerelease/mac/documentation/GraphicsImaging/Reference/CoreImageFilterReference/index.html)
