多個UITextfields返回Null IOS

Question

我在表單視圖上有多個文本字段。 我想在用戶單擊按鈕時附加它們。 但是只有其中一個返回文本字段中的值，其余的返回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);

    }

}

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

奇怪的是，如果字段值錯誤（例如11,45,20），if else方法將捕獲，它會按我的預期彈出警報視圖。

那么，似乎是什么問題呢？ 也許我不應該一次辭職嗎？

更改

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

至

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

您忘記添加下划線。
