how to convert lower case character to upper case?

Question

unichar c;

c = [myString characterAtIndex:0];

unichar catchcar = [c lowercaseString];

error : invalid reciever type unicar.

I know lowercaseString is used to covert String not character. Is there any solution?

Answer 1

you could do the following:

unichar catchcar = [[myString lowercaseString] characterAtIndex: 0];

If you have a a character only, do the following:

// given unichar c

unichar catchcar = [[[NSString stringWithCharacters:&c length:1] lowercaseString] characterAtIndex: 0];

Answer 2

Did that really hard?

unichar c = [[myString lowercaseString] characterAtIndex:0];

Try this.
