UIDatePicker錯誤時間

Question

我有一個UIDatePicker。我選擇上午2點30分，它將時間上午6點30分送給我。我究竟做錯了什麼？ 感謝

下面的代碼：

_datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, toolBar.frame.size.height, vcSize.width, 0)]; 
_datePicker.minimumDate = [NSDate date]; 
[_datePicker addTarget:self action:@selector(valueChanged:) forControlEvents:UIControlEventValueChanged]; 
_datePicker.minuteInterval = 15; 
_datePicker.timeZone = [NSTimeZone localTimeZone]; 
_datePicker.calendar = [[NSLocale currentLocale] objectForKey:NSLocaleCalendar];

Answer 2

you can select the date in to datePicker: 

NSDate *date = self.datePicker.date; 

一個問題，您選擇到日期選擇器將顯示標籤的任何日期：

datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(500, 160, 340, 300)]; 
    datePicker.datePickerMode = UIDatePickerModeDate; 
    datePicker.hidden = NO; 
    datePicker.date = [NSDate date]; 
    [datePicker addTarget:self 
        action:@selector(LabelChange:) 
     forControlEvents:UIControlEventValueChanged]; 
    [self.view addSubview:datePicker]; 

-(void)LabelChange:(id)sender 
{ 

NSDateFormatter *df = [[NSDateFormatter alloc] init]; 
    df.dateStyle = NSDateFormatterMediumStyle; 

    datelabel.text = [NSString stringWithFormat:@"%@", 
        [df stringFromDate:datePicker.date]]; 


if ([datePicker.date isEqualToDate:datePicker.date]) 
{ 
    NSLog(@"datePicker......"); 
} 

[df release]; 

}
