Removing object from NSMutableArray

Question

I stumbled across the following shortcut in setting up a for loop (shortcut compared to the textbook examples I have been using):

for (Item *i in items){ ...         


        

Answer 1

The former loop is a "for-each" loop in Objective C.

*i is a pointer to the direct item in the items-Array (most of the time this will be NSMutableArray).

This way you can operate directly on the item:

[items removeObject: i];

This (should) work - I am currently not working on my Mac and can't check it. However it might be that Objective-C Prevents removing objects while iterating over the collection (that is quite common in most languages).
