Multiline UILabel?

Question

Necesito insertar a UILabel texto de varias líneas. Hago lo siguiente:

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 se compone de dos elementos, por lo que debería haber dos cadenas. Pero el UITableViewCell contiene solo la primera cadena. En IB, configuré el recuento de líneas en 0 para UILabel cell.exsInfoLabel.

Answer 1

probar esto:

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]; 

Answer 2

probar antes setText:

cell.exsInfoLabel.numberOfLines = 2; 

O:

cell.exsInfoLabel.numberOfLines = arrEx.count;
