按照食谱配方,我使用以下方法添加了一个UIDatePicker:

    self.myDatePicker = [[UIDatePicker alloc] init];
    self.myDatePicker.center = self.view.center;
    [self.view addSubview:self.myDatePicker];

    [self.myDatePicker addTarget:self
        action:@selector(datePickerDateChanged:)
        forControlEvents:UIControlEventValueChanged];

    self.myDatePicker.datePickerMode = UIDatePickerModeTime;

所以它集中在一起,但我需要做些什么来移动它?我只想在界面中将其移动。

编辑:谢谢,Saturisk!通过使用frame:

进行初始化来解决此问题
- (void)viewDidLoad
{
  [super viewDidLoad];


  CGRect pickerFrame = CGRectMake(0, 70, 0, 0);

  self.myDatePicker = [[UIDatePicker alloc] initWithFrame:pickerFrame];
  [self.view addSubview:self.myDatePicker];

  [self.myDatePicker addTarget:self
  action:@selector(datePickerDateChanged:)
  forControlEvents:UIControlEventValueChanged];

  self.myDatePicker.datePickerMode = UIDatePickerModeTime;

}

更改其框架或initWithFrame。

self.myDatePicker.frame = CGRectMake(xPosition, yPosition, width, height);

self.myDatePicker = [[UIDatePicker alloc] initWithFrame: CGRectMake(xPosition, yPosition, width, height);
