Answer 3

从iOS 5开始，有4种方法可用

- (void)setLeftBarButtonItems:(NSArray *)items animated:(BOOL)animated;
- (void)setRightBarButtonItems:(NSArray *)items animated:(BOOL)animated;
- (void)setLeftBarButtonItems:(NSArray *)items;
- (void)setRightBarButtonItems:(NSArray *)items;

您可以在其中设置UIBarButtonItem

数组

示例：

NSArray * buttons = @[button1,button2];
[self.navigationItem setRightBarButtonItems:buttons];
