Question

I am adding string into a pickerView like this :

NSString *string = [NSString stringWithFormat:@"%@  %@", xxx, xxx];
[pickerViewObjects addObject:string];

what i want to do is to hide the first part of the string, or of there’s something to use like charachterAtIndex it will be useful because the first part of my string has a specific number of characters.

Use this method to get “(whitespaces) John”

NSString *string = @"Hello John";

    NSUInteger spacePosition = [string rangeOfString:@" "].location;

    NSMutableString *newString = [[NSMutableString alloc]init ];

    for (int i=0; i<spacePosition; i++)
        [newString appendString:@" "];

    NSString *otherPartofString = [string substringFromIndex:(spacePosition)];
    [newString appendString:otherPartofString];

    NSLog(@"new String is '%@'",newString);
    [newString release];
