NSCharacterSet *uppercaseSet = [NSCharacterSet uppercaseLetterCharacterSet];
NSString *str = @"test String";
NSRange range = [str rangeOfCharacterFromSet:uppercaseSet];

Now, if range.location != NSNotFound, your string has at least one uppercase character.

BOOL isUppercase = [[NSCharacterSet uppercaseLetterCharacterSet] characterIsMember:[s characterAtIndex:0]];

it will check the first char of your NSString if you want to check every char of your NSString run it in loop.

use this

NSString *myStr = @"YouR sTring";  
int count=0;  
for (i = 0; i < [myStr length]; i++) {
    BOOL uppercaseFlag = [[NSCharacterSet uppercaseLetterCharacterSet] characterIsMember:[myStr characterAtIndex:i]];
    if (uppercaseFlag == YES)
       count++;
}

if count is greater than 1, means it contains an Uppercase letter
