UIImage downloader spec using proxy placeholder. Anyone in favor of this idea?
@class JTImageProxy;
@interface UIImage (JTImageProxy)
+ (UIImage <JTImageProxy> *)imageWithURL:(NSURL *)URL;
@end
@class JTImageProxy;
@interface UIImage (JTImageProxy)
+ (UIImage <JTImageProxy> *)imageWithURL:(NSURL *)URL;
@end
#import <UIKit/UIKit.h>
@protocol JTImageProxy <NSObject>
- (NSURL *)URL;
- (CGFloat)expectedSize;
- (CGFloat)totalDownloadedSize;
- (CGFloat)progress;
- (NSError *)error;
- (void)cancelDownload;
- (void)restartDownload;
@end
@interface JTImageProxy : NSProxy <JTImageProxy>
@property (nonatomic, strong) NSURL *URL;
@property (nonatomic, strong) UIImage *image;
+ (JTImageProxy *)proxyWithURL:(NSURL *)URL;
@end
