objective C for-loop break and continue

Question

How can i use a 'break' statement within a for-loop which continues form a specified label?

ex;

outer: for(int i = 0;i<[arABFBmatches count];i++){     for(int i = 0;i<[arABFBmatches count];i++){         //         break _____;     } } 

How to break to outer?

Answer 1

Hard to say from your question. I'd interpret it that you want to skip the rest of the iterations of the inner loop and continue the outer loop?

for (int i = 0; i < [arABFBmatches count]; i++) {     for (int j = 0; j < [arABFBmatches count]; j++) {         if (should_skip_rest)             break; // let outer loop continue iterating     } } 

Note that I changed the name of your inner loop invariant; using i in both is inviting insanity.

If you want to break from both loops, I wouldn't use a goto. I'd do:

BOOL allDoneNow = NO; for (int i = 0; i < [arABFBmatches count]; i++) {     for (int j = 0; j < [arABFBmatches count]; j++) {         if (should_skip_rest) {             allDoneNow = YES;             break;         }     }     if (allDoneNow) break; } 

Answer 2

Roughly:

for(int i = 0;i<[arABFBmatches count];i++){     for(int j = 0;j<[arABFBmatches count];j++){         //         goto outer_done;     } } outer_done: 

Objective-C does not have labelled break.
