未定義的方法`initWithNibName'

Question

我剛剛開始使用RubyMotion學習iOS開發，我正在做這個tutorial。這似乎很容易理解，但現在我堅持了這個錯誤，我得到當我運行rake命令：

ColorController.rb:7:in `initWithColor:': undefined method `initWithNibName' for #<ColorController:0x9b4f470> (NoMethodError) 
    from SearchController.rb:46:in `open_color:' 
    from Color.rb:35:in `block in find:' 
    from query.rb:358:in `call_delegator_with_response' 
    from query.rb:128:in `connectionDidFinishLoading:' 

我到哪裏WHEW WELL THAT IS A TON OF CODE NOW ISN'T IT.是教程頁面上找到的部分和我卡在那裏。目前我的代碼看起來像：

# app_delegate.rb 
class AppDelegate 
    def application(application, didFinishLaunchingWithOptions:launchOptions) 
    @window = UIWindow.alloc.initWithFrame(UIScreen.mainScreen.bounds) 

    @search_controller = SearchController.alloc.initWithNibName(nil, bundle: nil) 
    @navigation_controller = UINavigationController.alloc.initWithRootViewController(@search_controller) 

    @window.rootViewController = @navigation_controller 
    @window.makeKeyAndVisible 
    true 
    end 
end 

# ColorController.rb 
class ColorController < UIViewController 
    attr_accessor :color 
    def initWithColor(color) 
    initWithNibName(nil, bunlde: nil) 
    self.color = color 
    self 
    end 
    def viewDidLoad 
    super 
    self.title = self.color.hex 

    @info_container = UIView.alloc.initWithFrame [[0, 0], [self.view.frame.size.width, 110]] 
    @info_container.backgroundColor = UIColor.lightGrayColor 

    self.view.addSubview @info_container 

    @color_view = UIView.alloc.initWithFrame [[10, 10], [90, 90]] 
    @color_view.backgroundColor = String.new(self.color.hex).to_color 

    self.view.addSubview @color_view 

    @color_label = UILabel.alloc.initWithFrame [[110, 30], [0, 0]] 
    @color_label.text = self.color.hex 
    @color_label.sizeToFit 

    self.view.addSubview @color_label 

    @text_field = UITextField.alloc.initWithFrame [[110, 60], [100, 26]] 
    @text_field.placeholder = "tag" 
    @text_field.textAlignment = UITextAlignmentLeft 
    @text_field.autocapitalizationType = UITextAutocapitalizationTypeNone 
    @text_field.borderStyle = UITextBorderStyleRoundedRect 

    self.view.addSubview @text_field 

    @add_button = UIButton.buttonWithType(UIButtonTypeRoundedRect) 
    @add_button.setTitle("Add", forState: UIControlStateNormal) 
    @add_button.setTitle("Adding", forState: UIControlStateDisabled) 
    @add_button.setTitleColor(UIColor.lightGrayColor, forState: UIControlStateDisabled) 
    @add_button.sizeToFit 
    @add_button.frame = [[@text_field.frame.origin.x + @text_field.frame.size.width + 10, @text_field.frame.origin.y], @add_button.frame.size] 

    self.view.addSubview(@add_button) 

    table_frame = [[0, @info_container.frame.size.height], [self.view.bounds.size.width, self.view.bounds.size.height - @info_container.frame.size.height - self.navigationController.navigationBar.frame.size.height]] 
    @table_view = UITableView.alloc.initWithFrame(table_frame, style: UITableViewStylePlain) 

    self.view.addSubview(@table_view) 

    end 
end 

# SearchController.rb 
class SearchController < UIViewController 
def viewDidLoad 
    super 
    self.title = "Search" 
    self.view.backgroundColor = UIColor.whiteColor 

    @text_field = UITextField.alloc.initWithFrame [[10, 10], [self.view.frame.size.width - 20, 30]] 
    @text_field.placeholder = "#abcabc" 
    @text_field.textAlignment = UITextAlignmentLeft 
    @text_field.autocapitalizationType = UITextAutocapitalizationTypeNone 
    @text_field.borderStyle = UITextBorderStyleRoundedRect 
    @text_field.center = CGPointMake(self.view.frame.size.width/2, self.view.frame.size.height/2 - 100) 

    self.view.addSubview @text_field 

    @search_button = UIButton.buttonWithType(UIButtonTypeRoundedRect) 
    @search_button.setTitle("Search", forState: UIControlStateNormal) 
    @search_button.setTitle("Loading", forState: UIControlStateDisabled) 
    @search_button.sizeToFit 
    @search_button.center = CGPointMake(self.view.frame.size.width/2, @text_field.center.y + 40) 

    self.view.addSubview @search_button 

    @search_button.when(UIControlEventTouchUpInside) do 
    @search_button.enabled = false 
    @text_field.enabled = false 

    hex = @text_field.text 
    hex = hex[1..-1] if hex[0] == "#" 

    Color.find(hex) do |color| 
     if color.nil? 
     @search_button.setTitle("None :(", forState: UIControlStateNormal) 
     else 
     @search_button.setTitle("Search", forState: UIControlStateNormal) 
     self.open_color(color) 
     end 
     @search_button.enabled = true 
     @text_field.enabled = true 
    end 

    end 

end 
def open_color(color) 
    self.navigationController.pushViewController(ColorController.alloc.initWithColor(color), animated: true) 
end 
end 

我也有另外兩個車型，我相信他們是不相關的，除非你要運行的代碼。

有誰能告訴我該怎麼辦？我意識到我正試圖調用initWithNibName方法，該方法在我的課程中沒有定義，但這是本教程的用法，因此我認爲它是正確的。我需要在ColorController課上定義它嗎？或者我可以用其他方式調用它？

Answer 1

你剛纔拼寫錯誤。

變化：

initWithNibName(nil, bunlde: nil) 

到：

initWithNibName(nil, bundle: nil)
