我想UIPopover
在 iPad 上创建一个UIDatePicker
里面,点击UITextField
.
我使用下面的代码来执行此操作,但我不知道tempButton.frame
代表什么或是什么tempButton
。
是否可以使用故事板做同样的事情?提前致谢。
UIViewController* popoverContent = [[UIViewController alloc] init]; //ViewController
UIView *popoverView = [[UIView alloc] init]; //view
popoverView.backgroundColor = [UIColor blackColor];
UIDatePicker *datePicker=[[UIDatePicker alloc]init];//Date picker
datePicker.frame=CGRectMake(0,44,320, 216);
datePicker.datePickerMode = UIDatePickerModeDateAndTime;
[datePicker setMinuteInterval:5];
[datePicker setTag:10];
[datePicker addTarget:self action:@selector(Result) forControlEvents:UIControlEventValueChanged];
[popoverView addSubview:datePicker];
popoverContent.view = popoverView;
popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
popoverController.delegate=self;
[popoverContent release];
[popoverController setPopoverContentSize:CGSizeMake(320, 264) animated:NO];
[popoverController presentPopoverFromRect:tempButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];//tempButton.frame where you need you can put that frame
