Xcode / iOS5：按下UITextField时显示UIDatePicker（+隐藏默认键盘）(Xcode/iOS5: Show UIDatePicker when UITextField is pressed (+ hide default keyboard))

我只想在UITextField处于活动状态时调用UIDatePicker。 当选择日期时，它应显示在相同的UITextField中。

我甚至不知道如何打电话给Picker。

谁能帮我？

I'd like to call UIDatePicker only when UITextField is active. When the date is picked, it should be shown in the same UITextField.

I even don't know how to call the Picker.

Can anyone help me?

最满意答案

有一个叫做委托方法

-(void)textFieldDidBeginEditing:(UITextField*)textField { [textField resignFirstResponder]; in this you have to do this pick = [[UIDatePicker alloc] init]; [pick setFrame:CGRectMake(0,200,320,120)]; [pick addTarget:self action:@selector(done) forControlEvents:UIControlEventValueChanged] [self.view addSubview:pick]; }

在

-(void)done { [textfield setText:pick.date]; }

在dealloc中释放选择

there is a delegate method called

-(void)textFieldDidBeginEditing:(UITextField*)textField { [textField resignFirstResponder]; in this you have to do this pick = [[UIDatePicker alloc] init]; [pick setFrame:CGRectMake(0,200,320,120)]; [pick addTarget:self action:@selector(done) forControlEvents:UIControlEventValueChanged] [self.view addSubview:pick]; }

in

-(void)done { [textfield setText:pick.date]; }

release the pick in dealloc
