Delegates are a real pain in the ars. Objective-C blocks rule! This are some category classes of my own to allow easy implementation of the basic iOS frameworks & APIs without the need of using delegation.
Available in Cocoa Pods
pod 'iOSBlocks/Cocoa'
You can also install only the subspecs you're interesting in. For example, install only UIKit block APIs:
pod 'iOSBlocks/UIKit'
- (void)pushViewController:(UIViewController *)viewController
animated:(BOOL)animated
onCompletion:(VoidBlock)completion;
&
- (void)popViewControllerAnimated:(BOOL)animated
onCompletion:(VoidBlock)completion;
+ (UIPopoverController *)popOverWithContentViewController:(UIViewController *)controller
showInView:(UIView *)view
onShouldDismiss:(VoidBlock)shouldDismiss
onCancel:(CancelBlock)cancelled;
+ (UIAlertView *)alertViewWithTitle:(NSString *)title
message:(NSString *)message
cancelButtonTitle:(NSString *)cancelButtonTitle
otherButtonTitles:(NSArray *)otherButtons
onDismiss:(DismissBlock)dismissed
onCancel:(CancelBlock)cancelled;
+ (UIActionSheet *)actionSheetWithTitle:(NSString *)title
style:(UIActionSheetStyle)sheetStyle
cancelButtonTitle:(NSString *)cancelButtonTitle
buttonTitles:(NSArray *)buttonTitles
disabledTitles:(NSArray *)disabledTitles
showInView:(UIView *)view
onDismiss:(DismissBlock)dismissed
onCancel:(CancelBlock)cancelled;
+ (void)mailWithSubject:(NSString *)subject
message:(NSString *)message
recipients:(NSArray *)recipients
andAttachments:(NSArray *)attachments
onCreation:(ComposeCreatedBlock)creation
onFinish:(ComposeFinishedBlock)finished;
+ (void)messageWithBody:(NSString *)body
recipients:(NSArray *)recipients
onCreation:(ComposeCreatedBlock)creation
onFinish:(ComposeFinishedBlock)finished;
+ (NSURLConnection *)sendAsynchronousRequest:(NSURLRequest *)request
didUpdateProgress:(ProgressBlock)progress
didReceiveData:(DataBlock)data
didReceiveResponse:(SuccessBlock)success
didFailWithError:(FailureBlock)fail;
+ (void)updateLocationWithDistanceFilter:(CLLocationDistance)filter
andDesiredAccuracy:(CLLocationAccuracy)accuracy
didChangeAuthorizationStatus:(StatusBlock)status
didUpdateLocations:(LocationBlock)located
didFailWithError:(FailureBlock)failed;
And more to come. Enjoy!
Take a look into the sample project. Everything is there.
Enjoy and collaborate if you feel this library could be improved.
