ADBImageView

ADBImageView inherits from UIImageView and allow asynchronous image loading from the cloud using NSURLConnectionDelegate protocol built-in Cocoa. It shows up a placeholder image and an activity indicator during the loading. It provides gesture for single tap and long press. It also provides caching functionalities taken from Toto Tvalavadze's TCImageView.

Try out the included demo project.

Simple usage:

• copy ADBImageView class into your project
• import ADBImageView.h in your class
• use as follow

ADBImageView *imageView = [[ADBImageView alloc] initWithFrame:CGRectMake(0.0, 0.0, 128.0, 128.0)];
imageView.delegate = self;
    
[imageView setImageWithURL:[NSURL URLWithString:@"http://www.albertodebortoli.it/GitHub/ADBImageView/H-Farm.jpg"]
          placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

• to load another image on the same object use

[imageView reloadWithUrl:[NSURL URLWithString:@"http://www.albertodebortoli.it/GitHub/ADBImageView/H-umus.jpg"]];

• use delegation pattern implementing ADBImageViewDelegate protocol and related optional delegate methods

#pragma mark - ADBImageViewDelegate
- (void)ADBImageView:(ADBImageView *)view willUpdateImage:(UIImage *)image { ... }
- (void)ADBImageView:(ADBImageView *)view didLoadImage:(UIImage *)image { ... }
- (void)ADBImageView:(ADBImageView *)view failedLoadingWithError:(NSError *)error { ... }
- (void)ADBImageViewDidSingleTap:(ADBImageView *)view { ... }
- (void)ADBImageViewDidLongPress:(ADBImageView *)view { ... }
