Я пытаюсь понять UiActionSheet с помощью выбора даты.
Получение 2 предупреждений, которые я не могу очистить, см. В коде в конце раздела кода.
предупреждение: семантическая проблема: отправка 'DeveloperTL *' параметру несовместимоговведите 'id'
и
предупреждение: семантическая проблема: отправка 'DeveloperTL *' параметру несовместимого типа 'id'
Есть идеи, как исправить эти предупреждения?
Код, который я скопировал из нескольких других примеров:
define kPickerTag 200
define SelectButtonIndex 1
define CancelButtonIndex 2
NSString *strPrintDate;
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex != [actionSheet cancelButtonIndex]) {
//set Date formatter
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"MM/dd/YYYY h:mm a"];
//Gets our picker
UIDatePicker *ourDatePicker = (UIDatePicker *) [actionSheet viewWithTag:kPickerTag];
NSDate *selectedDate = [ourDatePicker date];
NSString *msg = [[NSString alloc] initWithFormat:@"The date that you had selected was, %@", [formatter stringFromDate:selectedDate]];
[formatter release];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Date" message:msg delegate:nil cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
[alert show];
[alert release];
[msg release];
}
}

UIDatePicker *pickerView = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 50, 100, 116)];
[pickerView setTag:kPickerTag];

if( strPrintDate != @"" && strPrintDate != nil )
