如何在iPhone应用程序中拥有2个leftBarButtonItems，并且1是默认的后退按钮？

Question

I would like 2 leftBarButtonItems, but leave one of the items as the default back button for Navigation Controllers. I have set up:

self.navigationItem.leftBarButtonItems = [NSArray arrayWithObjects:archives, ???, nil];

where archives is a UIBarButtonItem I created, but do not know what the default back button is to include in the array. Any suggestions?

Answer 1

Make sure you set leftItemsSupplementBackButton to YES.

self.navigationItem.leftItemsSupplementBackButton = YES;
self.navigationItem.leftBarButtonItems = [NSArray arrayWithObjects:archives, nil];
