Xcode/iOS5:按下UITextField时显示UIDatePicker(+隐藏默认键盘)

Question

我只想在UITextField处于活动状态时调用UIDatePicker.选择日期时,它应显示在同一个UITextField中.

我甚至不知道如何打电话给Picker.

谁能帮我？

Answer 1

有一个名为的委托方法

-(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];
}

释放dealloc的选秀权
