If you need to split on a set of several different delimiters, use -[NSString componentsSeparatedByCharactersInSet:] . If you need to break a string into its individual characters, loop over the length of the string and convert each character into a new string.
Creating NSArray Objects Using Array Literals In addition to the provided initializers, such as initWithObjects: , you can create an NSArray object using an array literal. In Objective-C, the compiler generates code that makes an underlying call to the init(objects:count:) method.
A static, plain-text Unicode string object that bridges to String ; use NSString when you need reference semantics or other Foundation-specific behavior.
NSArray *arrayOfComponents = [yourString componentsSeparatedByString:@":"];
where yourString contains @"one:two:three"
and arrayOfComponents will contain @[@"one", @"two", @"three"]
and you can access each with NSString *comp1 = arrayOfComponents[0];
(https://developer.apple.com/documentation/foundation/nsstring/1413214-componentsseparatedbystring)
Try this:
NSString *testString= @"It's a rainy day";
NSArray *array = [testString componentsSeparatedByString:@" "];
Try componentsSeparatedByString:
Use this: [[string componentsSeparatedByString:@","][0];
