How can I word wrap with NSMutableAttributedString?

Question

NSArray *myArray = @[@"1st:array1", 
                     @"2nd:array2", 
                     @"3rd:array3"
                    ];
NSString *labelString = [myArray componentsJoinedByString:@"\n"];

In this codelabelStringcan be word wrapped.
But if use NSMutableAttributedString like this

NSAttributedString *resultString = [resultArray componentsJoinedByString:@"\n"];

it can't be joined by @"\n". Any other method is existed? Thanks.

It's not difficult. You just know one thing.
AttributedString can't have \n maybe. So you just put \n in NSString.
And just make NSAttributedString from this NSString.
Here this code. I hope this code help your work.

NSString *commentString;    
NSMutableArray *resultArray = [[NSMutableArray alloc]initWithCapacity:50];    

for (InstagramComment *comment in comments) {
    commentString = [NSString stringWithFormat:@"%@:%@\n", comment.user.username, comment.text];

    NSMutableAttributedString *styledCommentString = [[NSMutableAttributedString alloc]initWithString:commentString];
    [resultArray addObject:styledCommentString];
}

NSMutableAttributedString *resultString = [[NSMutableAttributedString alloc]init];

for (int i = 0; i < resultArray.count; ++i) {
    [resultString appendAttributedString:[resultArray objectAtIndex:i]];
} [cell.comment setAttributedText:resultString];
