NSString

How to check if NSString begins with a certain character

You can use the -hasPrefix: method of NSString:

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

IOS: string split

 
NSArray* foo = [@"10/04/2011" componentsSeparatedByString: @"/"];
NSString* day = [foo objectAtIndex: 0];
