Question

I have a UINavigationBar which title I would like to capitalize all letters so ‘word’ becomes ‘WORD’.

I would like to do the same for buttons within this nav bar.

I was wondering if is there anything like CSS text-transform:uppercase; attribute where it is possible to change the visual appearance of the word but once retrieving its value it stills returning its raw value.

Thank you in advance

As using [myString uppercaseString] has the downside of returning an uppercase string (well, it is not actually a downside ..) and not the original string, one option would be to set a UILabel with an all-caps font (Copperplate is just an example of an all-caps font, you will likely find a better one):

int height = navigationController.navigationBar.frame.size.height;
int width = navigationController.navigationBar.frame.size.width;

UILabel *navLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, width, height)];
navLabel.backgroundColor = [UIColor clearColor];
navLabel.textColor = [UIColor whiteColor];
navLabel.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
navLabel.font = [UIFont fontWithName:@"Copperplate" size:18];
navLabel.textAlignment = UITextAlignmentCenter;

self.navigationItem.titleView = navLabel;
