View contents of UITableViewCell - adding UILabels

Question

Currently, I have the following code for my cellForRowAtIndexPath on my UITableView:

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

    static NSString* CellIdentifier = @"Cell";
    UILabel* nameLabel = nil;
    UILabel* valueLabel = nil;
    UILabel *percentLabel = nil;

    UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier: CellIdentifier];
    if ( cell == nil ) 
    {
        inthere = YES;
        cell = [[[UITableViewCell alloc] initWithStyle: UITableViewCellStyleDefault 
                                       reuseIdentifier: CellIdentifier] autorelease];
        cell.selectionStyle = UITableViewCellSelectionStyleNone;

        nameLabel = [[[UILabel alloc] initWithFrame:CGRectMake( 7.0, 0.0, 140.0, 44.0 )] autorelease];
        nameLabel.tag = 21;
        nameLabel.font = [UIFont systemFontOfSize: 12.0];
        nameLabel.textAlignment = UITextAlignmentLeft;
        nameLabel.textColor = [UIColor darkGrayColor];
        nameLabel.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleHeight;
        nameLabel.backgroundColor = [UIColor clearColor];
        [cell.contentView addSubview: nameLabel];

        valueLabel = [[[UILabel alloc] initWithFrame: CGRectMake( 165.0, 0.0, 80, 44.0 )] autorelease];
        valueLabel.tag = 22;
        valueLabel.font = [UIFont systemFontOfSize: 11];
        valueLabel.textAlignment = UITextAlignmentRight;
        valueLabel.textColor = [UIColor blueColor];
        valueLabel.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight;
        valueLabel.backgroundColor = [UIColor clearColor];
        [cell.contentView addSubview: valueLabel];

        percentLabel = [[[UILabel alloc] initWithFrame: CGRectMake(245, 0.0, 65, 44.0 )] autorelease];
        percentLabel.tag = 24;
        percentLabel.font = [UIFont systemFontOfSize: 12];
        percentLabel.textAlignment = UITextAlignmentRight;
        percentLabel.textColor = [UIColor blueColor];
        percentLabel.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight;
        percentLabel.backgroundColor = [UIColor clearColor];
        [cell.contentView addSubview: percentLabel];
    }
    else
    {
        nameLabel = (UILabel*)[cell.contentView viewWithTag:21];
        valueLabel = (UILabel*)[cell.contentView viewWithTag:22];
        percentLabel = (UILabel *)[cell.contentView viewWithTag:24];
    }

   ...and then I initialize the text of each of these three labels...

}

But I would like these three labels to be different colors depending on the cell. For example, all cells in section 3 must have red Labels, and all cells in section 5 must have green Labels. But if I insert this into the code after initializing the text of all the shortcuts:

if(indexPath.section==3) {
    nameLabel.textColor = [UIColor redColor];
}
if(indexPath.section==5) {
    valueLabel.textColor = [UIColor greenColor];
}

then everything becomes spoiled, and the table is all buggy, the text is in odd places, and the labels are the wrong colors and a somewhat random look.

How can I specify the colors of these three labels for each individual cell in my table?

Answer 1

reset textColor ,

,

if (indexPath.section == 3) {

    nameLabel.textColor = [UIColor redColor];
    nameLabel.frame = CGRectMake(someX, someY, someWidth, someHeight);
    valueLabel.textColor = [UIColor blackColor];
    valueLabel.frame = CGRectMake(someX, someY, someWidth, someHeight);
}

if (indexPath.section == 5) {

    nameLabel.textColor = [UIColor blackColor];
    nameLabel.frame = CGRectMake(someX, someY, someWidth, someHeight);
    valueLabel.textColor = [UIColor greenColor];
    valueLabel.frame = CGRectMake(someX, someY, someWidth, someHeight);
}

. , , autorelease , release contentView.

Answer 3

The problem arises because UITableViewCells are randomly processed by the system . To do this, you must also set the default values ​​of the cell:

if(indexPath.section==3)
    nameLabel.textColor = [UIColor redColor];
else
    nameLabel.textColor = [UIColor blackColor];

By the way, your camera looks so complicated, I would recommend creating it using Interface Builder.
