Question

I have a simple question. How I indent a very long line. Let’s use the traditional 80 caracters.
This is a line in my code:

    NSString *count = [[NSString alloc] initWithString: [sTemp substringFromIndex:[sTemp rangeOfString:@"count="].location + [sTemp rangeOfString:@"count="].length]]; 

One solution was

    NSString *count = [[NSString alloc]                                 //line 1
                            initWithString: [sTemp substringFromIndex:
                                [sTemp rangeOfString:@"count="].location + 
                                [sTemp rangeOfString:@"count="].length]]; 

This is not the best sample, but the idea is:

1. Ok, the first line is the assignment and alloc thing.

2. The line 2 indent with a fell more right space. But, if the name of variable or type is very big, I will have the situation above. What I do?

   NSStringWithVeryBigType *bigNameVariable = [NSStringWithVeryBigType alloc] 
                     initWithString: [sTemp substringFromIndex:
   

3. IN second line I create a new NSString. I can be confuse if the line 3 and 4 (in a bad situation, not this) is the main function creation, or is this new one. Have a good rule about it? And if it have a big name too, what to do again…

In other words, in a big assignment line, what rule I have to fallow?

Answer 1

I’d do something like:

NSString *count = [[NSString alloc] initWithString: 
    [sTemp substringFromIndex:
         [sTemp rangeOfString:@"count="].location 
       + [sTemp rangeOfString:@"count="].length]];
