從plist中加載detailviewcontroller中的數據？

Question

我試圖從一個plist中是字典的陣列顯示數據：

<array> 
    <dict> 
     <key>title</key> 
     <string>RATATOUILLE</string> 
     <key>coverImage</key> 
     <string>rat.png</string> 
     <key>smallImage</key> 
     <string>rat-small.png</string> 
     <key>description</key> 
     <string>Spray a pan with cooking spray. Brown the onion and the garlic (do not let garlic burn!). Add all the veggies and the bay leaf and simmer covered for 2 hours. Sprinkle on the breadcrumbs and cook another 5 minutes. Remove the bay leaf and serve. 
5 servings, 0 POINTS each (if you eat the whole thing, count points for the bread crumbs)</string> 
    </dict> 

在RootViewController的數據顯示剛在細胞中細

。在detailviewcontroller我已經嘗試了相同的方法，它不顯示任何東西。我究竟做錯了什麼？ 下面的代碼：

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    NSDictionary *details = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Testdata" ofType:@"plist"]]; 

    coverImageView.image = [UIImage imageNamed:[details objectForKey:@"coverImage"]]; 
    titleLabel.text = [details objectForKey:@"title"]; 
} 

什麼，我不明白的是，它實際上是如何工作的。在RootViewController的我有這樣的方法：

-(id)initWithCoder:(NSCoder *)aDecoder { 

    if (self = [super initWithCoder:aDecoder]) { 
     NSString *path = [[NSBundle mainBundle] pathForResource:@"TestData" ofType:@"plist"]; 
     arrayIndex = [[NSArray alloc] initWithContentsOfFile:path]; 

    } 
    return self; 
} 

和數據從「arrayIndex」拉。 detailviewcontroller不一樣嗎？ ................... 編輯： 我想通了，做在tableviewcontroller的字符串：

NSString *selectedItem = [arrayIndex objectAtIndex:indexPath.row]; 
detailViewController.selectedItem = selectedItem; 

並加載數據的detailviewcontroller像這個：

coverImageView.image = [UIImage imageNamed:[selectedItem valueForKey:@"coverImage"]]; 
    titleLabel.text = [selectedItem valueForKey:@"title"];

我想你想念數組部分，你應該加載一個數組形式的plist，然後得到字典在適當的索引。順便說一下，你顯然已經在rootviewcontroller中加載了內存中的數據，所以你可以將它作爲屬性傳遞給詳細視圖以及要讀取的索引。
