尋找關於將Pre-Storyboard代碼（XCode4）移動到Storyboard代碼（XCode5）的教程

Question

我試圖去掌握XCode5，但大多數代碼示例都是XCode5之前版本。當然還有iOS7之前。主要問題是故事板。許多人希望知道如何在沒有Storyboard的情況下在SCode5中構建 - 但我不知道如何將預故事板代碼移動到故事板代碼。

例如。最出色的書「iOS中的地理位置」，Alasdair Allan，O'Reilly，2012年，充滿了幾個版本之前編寫的代碼。當然，當我在XCode5/iOS7級別進入XCode時，我不知道他們在各個部分討論了什麼。 我有種示例代碼工作的開始，但現在拋出一個錯誤，我無法弄清楚。我懷疑是因爲它試圖做到Code4的方式，而我在XCode5中。

無論如何 - 最好的教程是指出一個變化。 讓我舉個例子： 本書第一個例子的代碼是這樣的。

在書中的項目瀏覽圖片，它顯示

LocationAppDelegate.h 
LocationAppDelegate.m 
LocationViewController.h 
LocationViewController. 
LocationViewController.xib 

在我的顯示器，我都相同的文件除外。而不是「.xib」文件我有「Main.storyboard」

到目前爲止確定 - 我相信從我所讀到的，Main.storyboard是xib文件的新equivelant。 但是.h和.m文件中自動生成的代碼有很多不同之處。所以盡我所能，我至少讓位置服務在調試窗口中顯示一個虛擬位置。

但是 - 現在我有這個錯誤。那麼其實兩個錯誤。

第一，語義警告

LocationViewController.m:15:17: Method 'tableView:cellForRowAtIndexPath:' in protocol not implemented 

第二，與紅色的錯誤！馬克

LocationViewController.m:60:9: No visible @interface for 'UITableView' declares the selector 'dequeueReusableCellWithIndentifier:' 

，因爲它出現在書中的代碼是相當簡單的，但這個錯誤已經失去了我。

的代碼LocationViewController.m

    [super viewDidLoad]; 
    // Do any additional setup after loading the view, typically from a nib. 
}

    // Dispose of any resources that can be recreated. 
} 

#pragma mark - View lifecycle 






#pragma mark UITableViewDelegate Methods

     didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 
    //add code here 
} 

#pragma mark UITableViewDataSource Methods 

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tv { 
    return 1; 
} 

- (NSInteger) tableView:(UITableView *)tv numberOfRowsInSection:(NSInteger)section { 
    return 5; 
} 

- (UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath { 

    static NSString *identifier = @"cell"; 
    UITableViewCell *cell = 
    //[tv dequeueReusableCellWithIndentifier:@"cell"]; 
    [tv dequeueReusableCellWithIndentifier:@"cell"]; 
    if (cell == nil) { 
     cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault 
             reuseIdentifier:identifier]; 
     cell.accessoryType = UITableViewCellAccessoryNone; 

    return cell; 
    } 

}

和它的價值，從LocationAppDelegate.h代碼，其次是。 m

當然，大多數情況下，我想知道那個錯誤是什麼，但是如果有什麼指導原則可以指出什麼文件在進行什麼操作？

謝謝。

Answer 1

在這裏你可以找到答案 iOS7 storyboard in Xcode 5 keep growing vertically

• 提交一個版本的代碼的Xcode改變其情節串連圖板

  • 單擊情節串連圖板前。 Xcode會問你是否要升級。

  • 選擇隨時升級

  • 在這種狀態下，故事板是由Xcode中已經搞砸了。不要 擔心。只需關閉該項目。

  • 做一個「混帳藏匿」，並回到版本致力於在步驟0 上述

  • 再次打開項目。

Answer 2

我想你應該看看到this修復的Xcode 5分鏡腳本錯誤。

至於錯誤，你應該嘗試：

[tv dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath]; 

相反的：

[tv dequeueReusableCellWithIndentifier:@"cell"];
