Objective-C Split a String into an Array

Objective-C

Jun 262011

Split a string into an array of strings by using NSString's componentsSeparatedByString:


NSString *myString = @"This is a test";

NSArray *myWords = [myString componentsSeparatedByString:@" "];
// myWords is now: [@"This", @"is", @"a", @"test"]

If you need to split on a set of several different characters, use NSString's componentsSeparatedByCharactersInSet:
NSString *myString = @"Foo-bar/blee";

NSArray *myWords = [myString componentsSeparatedByCharactersInSet:

                      [NSCharacterSet characterSetWithCharactersInString:@"-/"]

                    ];

// myWords is now: [@"Foo", @"bar", @"blee"]
