Question

I was wondering how to capitalize a string found in an object in an NSMutableArray   An NSArray contains the string  April  at index 2  I want this to be changed to  APRIL    Is there something simple like this   viewNoteDateMonth text      displayDate objectAtIndex 2  capitalized

In case anyone needed the above in swift :

SWIFT 3.0 and above :

this will capitalize your string, make the first letter capital :

viewNoteDateMonth.text  = yourString.capitalized

this will uppercase your string, make all the string upper case :

viewNoteDateMonth.text  = yourString.uppercased()
