Remove UITabBarItem

How can I remove a UITabBarItem from a UITabBar?

I haven't tried anything, because I haven't found anything from Google searches or the documentation for UITabBar, UITabBarController, or UITabBarItem.

Thanks in advance! :)

Solution

  • UITabBar has an NSArray collection of items. Since the items property is an NSArray and not an NSMutableArray, you'd have to construct a new NSArray from the existing one devoid of the object you want to remove, then set the items property to the new array.

    /* suppose we have a UITabBar *myBar, and an int index idx */
NSMutableArray *modifyMe = [[myBar items] mutableCopy];
[modifyMe removeObjectAtIndex:idx];
NSArray *newItems = [[NSArray alloc] initWithArray:modifyMe];
[myBar setItems:newItems animated:true];
