How to capitalized first letter of Label - iphone

Question

Here's my code :-
I need to Change only the first letter of the Word to capitalized.
UILabel *lbl4=[[UILabel alloc]initWithFrame:CGRectMake(10, 90, 200, 30)];
lbl4.text= [NSString stringWithFormat:#"(%#)", [arrtype objectAtIndex:0]];
lbl4.font = [UIFont fontWithName:#"Helvetica" size:18];
lbl4.textColor=[UIColor blackColor];
lbl4.backgroundColor=[UIColor clearColor];

Answer 1

Capitalization is for string not label
use
[NSString capitalizedString]
to capitalise a string and set it as text to the label
lbl4.text= [[NSString stringWithFormat:#"(%#)", [arrtype objectAtIndex:0]]capitalizedString];

Answer 2

NSString *abc = #"demo";
abc = [NSString stringWithFormat:#"%#%#",[[abc substringToIndex:1] uppercaseString],[abc substringFromIndex:1] ];
NSLog(#"abc = %#",abc);

Answer 3

Use this
UILabel *lbl4=[[UILabel alloc]initWithFrame:CGRectMake(10, 90, 200, 30)];
NSString *abc = [NSString stringWithFormat:#"(%#)", [arrtype objectAtIndex:0]];
abc = [NSString stringWithFormat:#"%#%#",[[abc substringToIndex:1] uppercaseString],[abc substringFromIndex:1]];
lbl4.text = abc;
lbl4.font = [UIFont fontWithName:#"Helvetica" size:18];
lbl4.textColor=[UIColor blackColor];
lbl4.backgroundColor=[UIColor clearColor];

Answer 4

- (NSString *) capitalizedFirstLetter:(NSString *)stringToConvert
{
NSString *retVal = stringToConvert;
if (stringToConvert.length <= 1)
{
retVal = stringToConvert.capitalizedString;
}else
{
retVal= [NSString stringWithFormat:#"%#%#",[[retVal substringToIndex:1] uppercaseString],[retVal substringFromIndex:1] ];
}
return retVal;
}
call this method:
[self capitalizedFirstLetter:labelName or textFieldName];
