iphone开发 UIDatePicker UIPickerView使用（持续更新中）

一． UIDatePicker

UIDatePicker模式：

 

1.    UIDatePickerModeTime

 

  

 

2.    UIDatePickerModeDate

 

 

 

3.    UIDatePickerModeDateAndTime

 

 

4.    UIDatePickerModeCountDownTimer

 

 

 

2. 以下是在苹果官网UICatalog例子中看到的比较好的创建UIDatePicker代码：

 

- (void)createDatePicker

{

    datePickerView =[[UIDatePicker alloc] initWithFrame:CGRectZero];

    datePickerView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin;

    datePickerView.datePickerMode = UIDatePickerModeDate;

   

    //note we are using CGRectZero for the dimensions of our picker view,

    //this is because picker views have a built in optimum size,

    //you just need to set the correct origin in your view.

    //

    //position the picker at the bottom

    CGSizepickerSize = [myPickerView sizeThatFits:CGSizeZero];

    datePickerView.frame =[self pickerFrameWithSize:pickerSize];

   

    //add this picker to our view controller, initially hidden

    datePickerView.hidden = YES;

    [self.view addSubview:datePickerView];

}
