How can I capitalize all letters in an NSString? [duplicate]

Question

I'm trying to capitalize all letters in a NSString for a table cell label.

Here's my code:

  // cell title and subtitle
cell.nameLabel.text = listingNode.title;
[cell.nameLabel.text uppercaseString];

It doesn't seem to have any effect at all.

Answer 1

The method uppercaseString returns an uppercased representation of the receiver. Which means you need to collect the returned string and apply that to the label as text.

Try this,

NSString *uppercase = [cell.nameLabel.text uppercaseString]; cell.nameLabel.text =  uppercase; 

Answer 2

NSString * str=@"jit";

NSLog(@"%@",[str uppercaseString]);


cell.nameLabel.text=[str uppercaseString];

Answer 3

You need to just convert your string to uppercase

cell.nameLabel.text=[String_name uppercaseString];
