DBImageView 是非常简单的异步加载图片的对象。
Installation
The recommended approach for installating DBImageView is via the CocoaPods package manager, as it provides flexible dependency management and dead simple installation.
Podfile
platform :ios, '6.0' pod 'DBImageView', '~> 1.0' Integration
DBImageView has a simple integration:
#import "DBImageView.h" Add DBImageView:
DBImageView *imageView = [[DBImageView alloc] initWithFrame:(CGRect){ 10, 10, 60, 60 }]; Set the remote image path:
[imageView setImageWithPath:@"remote_image_URL"]; Options
You can set a placeholder:
[imageView setPlaceHolder:[UIImage imageNamed:@"Placeholder"]]; If you use a collection or a table, trigger the load action when you want
- (void) scrollViewWillBeginDragging:(UIScrollView *)scrollView { [DBImageView triggerImageRequests:NO]; } - (void) scrollViewDidEndDecelerating:(UIScrollView *)scrollView { [DBImageView triggerImageRequests:YES]; }
