conditional nsarray count
cocoa-touch, nsarray, nsmutablearray, objective-c, xcode
Solution
`enumerateObjectsUsingBlock:` doesn't return anything. I'd bet that code won't even compile (and, as your comment states, auto-completion doesn't work -- and it shouldn't).
Use NSArray's `indexesOfObjectsPassingTest: ` and take the `count` of the resulting `NSIndexSet`.

Problem
I want a count on an array where a sub array meets a condition. I thought I could do this, but I can't. ``` NSLog(@"%d",[[_sections enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) { [[obj objectAtIndex:4] isEqualToString:@"1"]; }] count]); ```
