+## Swift4用
+
+```swift:UIImageExtension.swift
+extension UIImage {
+ func tint(color: UIColor) -> UIImage {
+ UIGraphicsBeginImageContextWithOptions(size, false, 0)
+ color.setFill()
+ let drawRect = CGRect(x: 0, y: 0, width: size.width, height: size.height)
+ UIRectFill(drawRect)
+ draw(in: drawRect, blendMode: .destinationIn, alpha: 1)
+ let tintedImage = UIGraphicsGetImageFromCurrentImageContext()
+ UIGraphicsEndImageContext()
+ return tintedImage
+ }
+}
+```

```swift:UIImageExtension.swift
extension UIImage {
func tint(color: UIColor) -> UIImage {
UIGraphicsBeginImageContextWithOptions(size, false, 0)
color.setFill()
let drawRect = CGRectMake(0, 0, size.width, size.height)
UIRectFill(drawRect)
drawInRect(drawRect, blendMode: kCGBlendModeDestinationIn, alpha: 1)
let tintedImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return tintedImage
}
}
```
