Objective-C Language NSString Searching for a Substring
Example
To search if a String contains a substring, do the following:
NSString *myString = @"This is for checking substrings";
NSString *subString = @"checking";
BOOL doesContainSubstring = [myString containsString:subString]; // YES
If targeting iOS 7 or OS X 10.9 (or earlier):
BOOL doesContainSubstring = ([myString rangeOfString:subString].location != NSNotFound); // YES
