[問題] 關於UIBarButtonItem的問題

[lazyasa (asa)]

大家好
小弟我在viewDidLoad寫了
UIBarButtonItem *cancelToOp = [[UIBarButtonItem alloc]initWithTitle:@"取消"
                                           style:UIBarButtonItemStylePlain
                                          target:self
                                          action:@selector(back:)];
    UIBarButtonItem *sendToOp = [[UIBarButtonItem alloc]initWithTitle:@"送出"
                                            style:UIBarButtonItemStylePlain
                                           target:self
                                           action:@selector(saveToOP:)];
    UINavigationItem *navItem = [[UINavigationItem alloc]initWithTitle:@"碎碎念"];
    navItem.leftBarButtonItem = cancelToOp;
    navItem.rightBarButtonItem = sendToOp;

    [composeBar pushNavigationItem:navItem animated:NO];

然後希望在saveToOP的裡面點下按鈕之後讓按鈕disable
我寫在我的
- (IBAction) saveToOP:(id) sender{
self.navigationItem.rightBarButtonItem.enabled = NO;

可是卻沒有任何反應
請問是哪裡的問題呢？

→ SunnyHomeBoy:navItem.rightBarButtonItem = nil;
→ lazyasa:謝謝S大，後來不用程式刻button，用xib拉ui就可以了
