多個UITextfields返回Null IOS

Question

我有一個表單視圖上的多個文本框。我想在用戶點擊一個按鈕時追加它們。但是隻有其中一個返回textfield中的值，其餘的返回null。

.H

@property (nonatomic, strong) IBOutlet UITextField *textMonth; 
@property (nonatomic, strong) IBOutlet UITextField *textDay; 
@property (nonatomic, strong) IBOutlet UITextField *textYear; 
@property (nonatomic, strong) IBOutlet UITextField *textMeetingName; 

.M

@synthesize textDay=_textDay; 
@synthesize textMonth=_textMonth; 
@synthesize textYear=_textYear; 
@synthesize textMeetingName=_textMeetingName; 


- (BOOL)disablesAutomaticKeyboardDismissal { 
    return NO; 
} 
//this dismiss keyboard on ios 
- (BOOL)textFieldShouldReturn:(UITextField *)textField { 

     [_textMonth resignFirstResponder]; 
     [_textDay resignFirstResponder]; 
     [_textYear resignFirstResponder]; 
     [_textMeetingName resignFirstResponder]; 


    return YES; 
} 
//submit create folder request to dropbox 
- (IBAction)sendCreateFolderRequest:(id)sender{ 

    if ([_textMonth.text intValue]>12 ||[_textMonth.text intValue]<1) { 
     //alertview choose a number between 1 and 12 
     [self popUpAlertview:@"Please choose a month between 1 and 12"]; 
    } 
    else if ([_textDay.text intValue]>31 || [_textDay.text intValue]<1){ 
     //alert view choose a number between 1 and 31 
     [self popUpAlertview:@"Please choose a day between 1 and 31"]; 
    } 
    else if ([_textYear.text intValue]<0){ 
     //alert view please enter a correct year 
     [self popUpAlertview:@"Please enter a correct year"]; 
    } 
    else if ([_textMeetingName.text length]<=1){ 
     //alert view meeting name is too short please enter a longer name 
     [self popUpAlertview:@"Name is too short. Please enter a longer name"]; 
    } 
    else{ 

     NSString *sendFolderName=[NSString stringWithFormat:@"/Up2Date/%@.%@.%@.%@",_textMonth.text,textDay.text,textYear.text,textMeetingName.text]; 

     NSLog(@"Send folder name %@",sendFolderName); 

    } 

} 

輸入是11,12,13,asdaad 輸出爲Send folder name /Up2Date/11.(null).(null).(null)

奇怪的是我，如果其他方法捕獲，如果字段值是錯誤的，如11， 45,20它彈出警報視圖，如我所料。

那麼，似乎是什麼問題？也許我不應該立即辭去他們的第一反應者？

變化

NSString *sendFolderName=[NSString stringWithFormat:@"/Up2Date/%@.%@.%@.%@",_textMonth.text,textDay.text,textYear.text,textMeetingName.text]; 

到

NSString *sendFolderName=[NSString stringWithFormat:@"/Up2Date/%@.%@.%@.%@",_textMonth.text,_textDay.text,_textYear.text,_textMeetingName.text]; 

你忘了添加下劃線。
