我正在我的 View Controller 类中创建自定义日期选择器。然后我需要另一个 View Controller 类中的日期选择器。所以我想创建任何 View Controller 类都可以使用并显示日期的通用日期选择器。那么我该如何使用它。请分享代码。
我使用这个代码:
actionSheet = [[UIActionSheet alloc] initWithTitle"Date" delegate:self
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
[actionSheet setBackgroundColor:[UIColor grayColor ]];
[actionSheet setFrame:CGRectMake(0, 470, 375, 200)];
datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake ( 0, 10, 300, 100)];
dateFormatter = [[NSDateFormatter alloc] init];
datePicker.datePickerMode = UIDatePickerModeDate;
[dateFormatter setDateFormat"MM/dd/yyyy"];
[datePicker addTarget:self actionselector(dateChanged) forControlEvents:UIControlEventValueChanged];
[actionSheet addSubview:datePicker];
UIToolbar *toolbarPicker = [[UIToolbar alloc] init];
toolbarPicker.backgroundColor=[UIColor grayColor];
// toolbarPicker.barStyle=UIBarStyleBlackOpaque;
[toolbarPicker sizeToFit];
NSMutableArray *itemsBar = [[NSMutableArray alloc] init];
//calls DoneClicked
UIBarButtonItem *btnDone = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self actionselector(doneClicked)];
[itemsBar addObject:btnDone];
[toolbarPicker setItems:itemsBar animated:YES];
[actionSheet addSubview:toolbarPicker];
[self.view addSubview:actionSheet];
}
-(IBAction)dateChanged{
self.dateEntry.text = [dateFormatter stringFromDate:[datePicker date]];
}
-(IBAction)doneClicked{
[actionSheet removeFromSuperview];
self.dateEntry.userInteractionEnabled = YES;
}
创建 UIView/NSObject
的自定义类,在那里添加您的逻辑,然后实现委托(delegate)设计模式来管理它。
如果您需要对此进行进一步说明,请告诉我。
