Multiline UILabel?

Question

I need insert to UILabel multiline text. I do the following:

NSMutableString * spName = [[NSMutableString alloc ]initWithString:@""];

for (NSUInteger i=0; i<arrEx.count; ++i)
{
    ExInfo * exInf = [arrEx objectAtIndex:i];
    [spName appendString:[MyObject getName:exInf.spNum]];
    [spName appendString:@" "];
    [spName appendString:exInf.totalTime];
    [spName appendString:@"\n"];        
}

CGSize size = [spName sizeWithFont:[UIFont systemFontOfSize:14] 
                 constrainedToSize:constraint
                     lineBreakMode:UILineBreakModeWordWrap];

[cell.exsInfoLabel setFrame:CGRectMake(CELL_CONTENT_MARGIN, top, CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), size.height)];
[cell.exsInfoLabel setText:spName];
[spName release];

arrEx consists of two items, so it should be two strings. But the UITableViewCell contains only the first string. In IB I set count of lines to 0 for the UILabel cell.exsInfoLabel.

Answer 1

Try before setText:

cell.exsInfoLabel.numberOfLines = 2;

Or:

cell.exsInfoLabel.numberOfLines = arrEx.count;

Answer 2

try this:

CGSize labelsize;
UILabel *commentsTextLabel = [[UILabel alloc] init];
[commentsTextLabel setNumberOfLines:0];
[commentsTextLabel setBackgroundColor:[UIColor clearColor]];
NSString *text = @"yourtextString";
[commentsTextLabel setFont:[UIFont fontWithName:@"Helvetica"size:14]];
labelsize = [text sizeWithFont:commentsTextLabel.font 
             constrainedToSize:CGSizeMake(268, 2000.0) 
                 lineBreakMode:UILineBreakModeWordWrap];
commentsTextLabel.frame = CGRectMake(10, 24, 268, labelsize.height);
[cell.contentView addSubview:commentsTextLabel];
[commentsTextLabel release];
