iOS のバージョンを 8.2 に更新しましたが、UIDatePicker と UITextfield のキーボードの非表示に関するいくつかの問題に直面しています。これがdatepickerの私のコードです:
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
[textField resignFirstResponder];
UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(0, 0,self.view.bounds.size.width, self.view.bounds.size.height)];
[myView setBackgroundColor:[UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.5]];
[self.view addSubview:myView];
UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height - 244, self.view.bounds.size.width, 44)];
UIBarButtonItem *done = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(dismissActionSheet)];
toolbar.items = @[[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil], done];
toolbar.barStyle = UIBarStyleBlackOpaque;
[self.view addSubview:toolbar];
UIDatePicker *datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height - 200, 0, 0)];
datePicker.datePickerMode = UIDatePickerModeDate;
datePicker.hidden = NO;
datePicker.date = [NSDate date];
datePicker.maximumDate = [NSDate date];
[datePicker addTarget:self
action:@selector(LabelChange:)
forControlEvents:UIControlEventValueChanged];
[self.view addSubview:datePicker];
}
しかし、キーボードは隠れていません。
