标题[问题] 关於UIBarButtonItem的问题
时间Fri Apr 13 17:02:33 2012
大家好
小弟我在viewDidLoad写了
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的里面点下按钮之後让按钮disable
我写在我的
- (IBAction) saveToOP:(id) sender{
self.navigationItem.rightBarButtonItem.enabled = NO;
可是却没有任何反应
请问是哪里的问题呢？
