CXAAutoRemovalNotification

Notice: observers of NSNotificationCenter are not required to un-register in their deallocation since iOS 9 / OS X 10.11: (https://developer.apple.com/library/prerelease/mac/releasenotes/Foundation/RN-Foundation/index.html#10_11NotificationCenter)

Less boilerplate code for NSNotificationCenter.

Usage

Simply add NSObject+CXAAutoRemovalNotification.{h|m} to your project.

Whereever you need NSNotificationCenter to observe using block by - addObserverForName:object:queue:usingBlock:, just replace it with -cxa_addObserverForName:object:queue:usingBlock:, or if don't care object and queue, use the shorter - cxa_addObserverForName:usingBlock: for your notification observer. CXAAutoRemovalNotification will take care of the observer removal in deallocation.

Example

__weak typeof(self) weakSelf = self;
[self cxa_addObserverForName:UIContentSizeCategoryDidChangeNotification usingBlock:^(NSNotification *note) {
   [weakSelf.tableView reloadData];
}];
