只删除一个RightBarButtonItem

Question

在导航栏中我添加了两个正确的barButtonItems:

[self.navigationItem setRightBarButtonItems:@[firstBarButton,secondBarButton]];

现在当我点击firstBarButtonItem想要删除它.我知道当我只有一个UIBarButtonItem时:

self.navigationItem.rightBarButtonItem = nil;

当rightBarButtonItems是两个时,我该怎么办？

Answer 1

只需设置其中一个:

[self.navigationItem setRightBarButtonItem:secondBarButton];
