在同一視圖控制器中的兩個UI採集器目標C？

所以我得到了我的用戶界面選擇器，但它顯示的是每個用戶界面選擇器的相同數據，但我希望它能在一個用戶界面中顯示鬍子陣列和另一個顏色。目前在映像中顯示的是將相同的數據分配給每個陣列。在同一視圖控制器中的兩個UI採集器目標C？

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 

    _colourSourceArray = [[NSArray alloc] initWithObjects:@"No Frame",@"Red", @"Green", @"Blue", @"Black",@"Yellow", nil ]; 
    _MustacheArray = [[NSArray alloc]initWithObjects:@"None",@"Pencil",@"The Professor",@"The Regent",@"Hipster",@"Super Mario", nil]; 

    [_picker selectRow:0 inComponent:0 animated:YES]; 
    [_notcolourpicker selectRow:1 inComponent:0 animated:YES]; 

    _picker.tag=0; 
    _notcolourpicker.tag=1; 
} 

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

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component 
{ 
    switch (component) { 
     case 0: 
      return _colourSourceArray.count; 
      break; 
     case 1: 
      return _MustacheArray.count; 
     default: 
      break; 
    } 

    return 0; 
} 

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component 
{ 
    switch (component) { 
     case 0: 
      return [_colourSourceArray objectAtIndex:row]; 
      break; 
     case 1: 
      return [_MustacheArray objectAtIndex:row]; 
     default: 
      break; 
    } 

    return 0; 
} 

-(IBAction)returnToExportSettingsVC:(UIStoryboardSegue *)segue 
{ 
    // Nothing needed here. 
} 

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component 
{ 
    if (component == 0) { 
     NSLog(@"First"); 

     NSString *s = _colourSourceArray[row]; 

     _selectedcolour = s; 
     NSLog(_selectedcolour); 
    } 
    else 
     if(component == 1){ 
      NSLog(@"Second"); 
      NSString *d = _MustacheArray[row]; 

      _selectedmustache=d; 

      NSLog(_selectedmustache); 
     } 

    /// Used if you wist to assign the selected row to a label to show a users selection. 
    //_label.text= [_MustacheArray objectAtIndex:[mostachepicker selectedRowInComponent:1]]; 
}

只需在故事板中的選取器視圖中添加一個'tag'，然後從數據源返回數據時，通過執行'if picker.tag == 1 {...} else檢查哪個選擇器正在請求數據if picker.tag == 2 {...}' – sbarow

的問題是，既選擇器視圖調用到相同的數據源/委託方法。如果您正在按照這種方式構建代碼，則需要檢查pickerView參數以查看哪些選擇器查看它，然後開啓該功能。
