Blocks example in ios5 [closed]

Question

I am a bit familier with the concepts of Blocks but I don't know how to create them in iOS5. Can anyone provide me with a simple example ? Much appreciated :)

Answer 1

Use this simple example in Blocks..

int multiplier = 7;
int (^myBlock)(int) = ^(int num) {
return num * multiplier;
};



NSLog(@"Sum = %d",myBlock(20));
Then you will get as 140
