How to check if NSString begins with a certain character

How do you check if an NSString begins with a certain character (the character *).

The * is an indicator for the type of the cell, so I need the contents of this NSString without the *, but need to know if the * exists.

You can use the -hasPrefix: method of NSString:

NSString* output = nil;
if([string hasPrefix:@"*"])
    output = [string substringFromIndex:1];
