Question

I have a large custom UITableView with UILabels in each row, and I’d like to display certain texts in Black or Green color.

I feed the cells with the NSString's from a NSArray. Suppose I want to display in black only the the NSString from index 30.

I’m Trying something like this, but it’s not working:

NSIndexPath *indexPathWithBlackText = [NSIndexPath indexPathForRow:30 inSection:[indexPath section]];

    if (indexPath.row == indexPathWithBlackText.row) {  
        //Label with text in black 
        topLabel.textColor = [UIColor colorWithRed:0.25 green:0.0 blue:0.0 alpha:1.0];
        topLabel.highlightedTextColor = [UIColor colorWithRed:1.0 green:1.0 blue:0.9 alpha:1.0];
    } else {
        //Label with text in green 
        topLabel.textColor = [UIColor colorWithRed:0.122 green:0.467 blue:0.255 alpha:1.00];
    }

Any hints on the right direction will be much appreciated. Thanks!

Answer 1

In this UITableViewDataSource delegate method:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

Write this:

if ([self isBlackRow:indexPath.row]) {
    // Your label reference, change color to black here.
} else {
    // Your label reference, change color to green here. 
}

Make a method to determine if the row is black or not

- (BOOL)isBlackRow:(NSInteger)row {
    NSArray* blackRows = [NSArray arrayWithObjects:[NSNumber numberWithInt:30], [NSNumber numberWithInt:11], nil];

    for (NSNumber* number in blackRows) {
        if (number.intValue == row) {
            return YES;
        }
    }

    return NO;
}
