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？
