Objective-C Language Fast Enumeration Fast enumeration of an NSArray
Example
This example shows how to use fast enumeration in order to traverse through an NSArray.
When you have an array, such as
NSArray *collection = @[@"fast", @"enumeration", @"in objc"];
You can use the for ... in syntax to go through each item of the array, automatically starting with the first at index 0 and stopping with the last item:
for (NSString *item in collection) {
NSLog(@"item: %@", item);
}
In this example, the output generated would look like
// item: fast
// item: enumeration
// item: in objc
