LCWebImage is an asynchronous image loading framework based on AFNetworking, which supports memory and disk caching, and provides functions such as custom caching, custom image decoding, and custom network configuration.
Animation playback is not supported by default. If you need to support animation, you can implement custom decoding (such as YYImage).
- iOS 9.0+
- Xcode 11.0+
- AFNetworking 4.0+
// UIImageView
[imageView lc_setImageWithURL:[NSURL URLWithString:@"https://xxx"]];
// UIButton
[button lc_setImageWithURL:[NSURL URLWithString:@"https://xxx"] forState:(UIControlStateNormal)];Use YYImage to implement custom decoding
// custom
[(LCAutoPurgingImageCache *)[LCImageDownloader defaultInstance].imageCache setCustomDecodedImage:^UIImage * _Nonnull(NSData * _Nonnull data, NSString * _Nonnull identifier) {
return [[YYImage alloc] initWithData:data scale:UIScreen.mainScreen.scale];
}];Load image
YYAnimatedImageView *imageView = [[YYAnimatedImageView alloc] init];
[imageView lc_setImageWithURL:[NSURL URLWithString:@"https://xxx"]];Note: There is a display problem with YYImage above iOS 14. The source code of
YYAnimatedImageViewneeds to be modified as follows:
- (void)displayLayer:(CALayer *)layer {
// modified code
UIImage *currentFrame = _curFrame;
if (currentFrame) {
layer.contentsScale = currentFrame.scale;
layer.contents = (__bridge id)currentFrame.CGImage;
} else {
// If we have no animation frames, call super implementation. iOS 14+ UIImageView use this delegate method for rendering.
if ([UIImageView instancesRespondToSelector:@selector(displayLayer:)]) {
[super displayLayer:layer];
}
}
// source code
// if (_curFrame) {
// layer.contents = (__bridge id)_curFrame.CGImage;
// }
}
To integrate LCWebImage into your Xcode project using CocoaPods, specify it in your Podfile:
pod 'LCWebImage'- Download everything inside the LCWebImage folder;
- Add (drag and drop) the source files in LCWebImage to your project;
- Add
AFNetworking/NSURLSessioncode.
