數據庫從選擇器視圖和日期視圖中接收NULL

Question

在我的應用程序我添加文本委託和setBirthDate方法採取日期 和setGender設置性別從選擇器視圖 後用戶選擇出生日期和性別，我試圖將它們發送到數據庫。 當我用NSLog打印值時，它顯示了他選擇的值，但是當我將它發送到數據庫時，它顯示NULL！

這是我的代碼

-(void)setBirthDate{ 
    actionsheet = [[UIActionSheet alloc] initWithTitle:nil delegate:nil cancelButtonTitle:nil  destructiveButtonTitle:nil otherButtonTitles:nil]; 
    [actionsheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent]; 

    CGRect pickframe= CGRectMake(0, 44, 0, 0); 
    UIDatePicker *picker = [[UIDatePicker alloc] initWithFrame:pickframe]; 
    [picker setDatePickerMode:UIDatePickerModeDate]; 

    [actionsheet addSubview:picker]; 

    UIToolbar *controlToolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, actionsheet.bounds.size.width, 44)]; 
    [controlToolBar setBarStyle:UIBarStyleBlack]; 
    [controlToolBar sizeToFit]; 

    UIBarButtonItem *space = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil]; 
    UIBarButtonItem *setButton = [[UIBarButtonItem alloc] initWithTitle:@"Set" style:UIBarButtonItemStyleDone target:self action:@selector(dissmisBirthDate)]; 
    UIBarButtonItem *cancel = [[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(cancelDateSet)]; 

    [controlToolBar setItems:[NSArray arrayWithObjects:space,setButton,cancel, nil] animated:NO]; 

    [actionsheet addSubview:controlToolBar]; 
    [actionsheet showInView:self.view]; 
    [actionsheet setBounds:CGRectMake(0, 0, 320, 485)]; 
    check5=TRUE; 
    [self ShowGeneral]; 
} 

-(void)dissmisBirthDate 
{ 
    NSArray *listView = [actionsheet subviews]; 

    for (UIView *subView in listView) { 
     if ([subView isKindOfClass:[UIDatePicker class]]) { 
      BirthDate = [(UIDatePicker *)subView date]; 
     } 
    } 
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
    [dateFormatter setDateFormat:@"yyyy-MM-dd"]; 
    [BirthDateTimeText setText:[dateFormatter stringFromDate:BirthDate]]; 
    [actionsheet dismissWithClickedButtonIndex:1 animated:YES]; 
} 

-(void)cancelDateSet 
{ 
    [actionsheet dismissWithClickedButtonIndex:1 animated:YES]; 
} 

-(void)GenderPickerView 
{ 
    genderArrayTime =[[NSMutableArray alloc]initWithObjects:@"ذكر",@"انثى",nil]; 
    actionsheet = [[UIActionSheet alloc] initWithTitle:nil delegate:nil cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; 
    [actionsheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent]; 
    GenderPickerTime = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 44, 320, 485)]; 
    [actionsheet addSubview:GenderPickerTime]; 
    GenderPickerTime.delegate = self; 
    GenderPickerTime.showsSelectionIndicator = YES; 

    UIToolbar *controlToolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, actionsheet.bounds.size.width, 44)]; 
    [controlToolBar setBarStyle:UIBarStyleBlack]; 
    [controlToolBar sizeToFit]; 

    UIBarButtonItem *space = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil]; 

    UIBarButtonItem *cancel = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(cancelPickerSet)]; 

    [controlToolBar setItems:[NSArray arrayWithObjects:space,cancel, nil] animated:NO]; 
    [actionsheet addSubview:controlToolBar]; 
    [actionsheet showInView:self.view]; 
    [actionsheet setBounds:CGRectMake(0, 0, 320, 485)]; 
    [GenderPickerTime selectRow:0 inComponent:0 animated:YES]; 
    genderTextTime.text = [NSString stringWithFormat:@"%@",[genderArrayTime objectAtIndex:0]]; 
    gender = [NSString stringWithFormat:@"%@",genderTextTime.text]; 
    NSLog(@"%@",gender); 
    check4=TRUE; 
    [self ShowPersonal]; 
} 

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component 
{ 
    if (pickerView == GenderPickerTime) { 
     return 2; 
    } 
} 

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView { 
    return 1; 
} 

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component 
{ 
    if (pickerView == GenderPickerTime) { 
     genderTextTime.text = [NSString stringWithFormat:@"%@",[genderArrayTime objectAtIndex:row]]; 
    } 
} 

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component 
{ 
    if (pickerView == GenderPickerTime) { 
     return [genderArrayTime objectAtIndex:row]; 
    } 
} 

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField 
{ 
    if ([textField isEqual:genderTextTime]) { 
    [self GenderPickerView]; 
    } 
} 

這裏的數據庫代碼：

NSString *post =[[NSString alloc] initWithFormat:@"fname=%@&sname=%@&gender=%@&email=%@&mobile_number=%@&nID=%@&birth=%s&place=%@&schoole_stage=%s&interest=%s&message=%s",FirstNameTextTime.text, LastNameTextTime.text , gender , EmailTextTime.text , PhoneTextTime.text , IdentityNumberTextTime.text, BirthDateTimeText.text , LivingPlaceTextTime.text , "gr","exh","gsddgf"]; 
NSData *dataURL = [post dataUsingEncoding:NSUTF8StringEncoding]; 
NSURL *url = [NSURL URLWithString:@"http://....?"]; 
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; 

[request setHTTPMethod:@"POST"]; 
[request setHTTPBody:dataURL]; 

NSURLResponse *response; 
NSError *err; 
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err]; 
NSLog(@"responseData: %@", responseData); 
NSString *strResult = [[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding]; 
NSLog(@"%@",strResult); 

這是我得到

FNAME =（空）&的sname =（空）&性別=（ null）& email=ali@h.com & mobile_number = 0569327234 & nID =（null）&出生= 2013年10月14日&地點=（空）& schoole_stage = GR &興趣= EXH &消息= gsddgf

另外我使用故事板和i。從3視圖控制器收集的信息我試圖通過數據之間的視圖，但它再次通過（NULL）... ahhhh

我解決了它不是從選擇器的問題，這是因爲當我從視圖移動到另一個我需要傳遞數據。
