Невозможно получить два сборщика Просмотр, чтобы показать в одной раскадровке

Question

Кажется, я не могу получить 2 Picker Views, чтобы показать их в одной раскадровке. Я могу получить каждый из них индивидуально, но не два. Я получаю непризнанную причину выбора селектора [JobLocation salesman]. Это должно быть [SalesLocation salesman]. Я просто не могу понять. Часть с self.jobNo.inputView = [self jobPicker] работает , но не self.saleNo.inputView = [self salesPicker], см. Код ниже, где я получаю перерыв.

- (NSString*)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component 
{ 
     NSString *result = nil; 

    if (pickerView.tag == 1) { 
     itemS = _feedItemsS[row]; 
     return itemS.salesman; 
    } 
    else if(pickerView.tag == 2) { 
     itemJ = _feedItemsJ[row]; 
     return itemJ.jobdescription; //I GET BREAK ON THIS LINE 
    } 
     return result; 
}

Answer 1

В itemsDownloaded вы назначая те же вещи как _feedItemsS и _feedItemsJ. Либо они оба будут JobLocation объектов, либо оба будут SalesLocation объектов в зависимости от того, что скачано.

Попробуйте NSLog(@"Incoming array: %@", items); внутри itemsDownloaded, чтобы увидеть, что назначается.
