| | | | | Blocks in Objective-C In Objective-C we are using the blocks(completion handlers) with functions as follows : [code language="obj-c"] - (void)yourFunctionName:(NSString *)yourString withCompletionHandler:(void (^)(NSString *yourResult))block; [/code] Closures in Swift Closures are self-contained blocks of functionality that can be passed around and used in your code. Closures in Swift are similar to blocks in C and Objective-C ... Read more | |
