If I have a instance method and within this method I do something like this:
NSString *peopleString = [peopleList componentsJoinedByString: @", "];
...
UILabel *likeLabel = [[UILabel alloc] initWithFrame:CGRectMake(16.0+6.0f, 4.0f, 252.0f, 12.0f)];
[likeLabel setText:peopleString];
[likeLabel setFont:[UIFont fontWithName:@"Arial" size:12]];
[likeRow addSubview:likeLabel];
[likeLabel release];
The componentsJoinedByString doesn't contain a new, copy or alloc, thus I don't have to release it. What I'm wondering though is, when my peopleString gets deallocated. Might it happen to early? Meaning, before I can set the text in my label. Should I better use a [[NSString alloc] initWithString:[peopleList componentsJoinedByString: @", "]]; and release it at the end of this method?
