ios - 关闭模态视图 Controller 后如何正确对齐 rightBarButtonItem？

Question

从 iOS 7 开始，UINavigationBar 中的 rightBarButtonItem 在关闭模态视图 Controller 后会向下移动。顶部屏幕截图显示了正确的对齐方式。底部屏幕截图显示关闭模态视图 Controller 后的错误对齐。

- (void) viewDidLoad
{
    [super viewDidLoad];

    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] 
        initWithTitle:@"" 
        style:UIBarButtonItemStyleDone 
        target:self
        action:@selector(didPressRightBarButtonItem)
    ];
    [self.navigationItem.rightBarButtonItem 
        setImage:[UIImage imageNamed:@"shareLightFlat"]
    ];
}

- (void) didPressRightBarButtonItem
{
    [self.navigationController 
        presentViewController:[[SomePage alloc] init] 
        animated:YES 
        completion:nil];
}

在 SomePage 中，我用它来解雇自己:

[self dismissViewControllerAnimated:YES completion:nil];

你不需要使用initWithTitle: @ ""

试试这个:

UIBarButtonItem *editBarButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"myImage"] style:UIBarButtonItemStyleDone target:self action:@selector(myAction:)];

self.navigationItem.rightBarButtonItems = @[editBarButton];
