我已成功將我的plist保存到文檔目錄！現在，我無法加載回

Question

此代碼精美的作品對我的plist保存到文檔目錄。

- (void)viewDidLoad { 
[super viewDidLoad]; 
self.navigationItem.rightBarButtonItem = self.addButtonItem; 
NSString *path = [[NSBundle mainBundle] pathForResource:@"TitleArray" ofType:@"plist"]; 
NSMutableArray *tmpArray = [[NSMutableArray alloc]initWithContentsOfFile:path]; 
self.titles = tmpArray; 
[tmpArray release]; 

//TESTING NEW CODE FOR SAVING TO DOC DIR 
NSError *error; 
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *docDirPath = [documentsDirectory stringByAppendingPathComponent:@"TitleArray.plist"]; 

NSFileManager *fileManager = [NSFileManager defaultManager]; 

if(![fileManager fileExistsAtPath: docDirPath]) 
{ 
    NSString *bundle = [[NSBundle mainBundle] pathForResource:@"TitleArray" ofType:@"plist"]; 

    [fileManager copyItemAtPath:bundle toPath:docDirPath error:&error]; 

         NSLog(@"plist is copied to Directory"); 
         } 

我一直無法弄清楚如何將plist加載迴應用程序！

任何人都可以幫忙嗎？謝謝。

Answer 1

NSString *path = [documentsDirectory stringByAppendingPathComponent:@"TitleArray.plist"]; 
NSArray * myList = [NSArray arrayWithContentsOfFile:path]; 
NSMutableArray *tmpArray = [myList mutableCopy]; 
self.titles = tmpArray; 
[tmpArray release]; 

沒有工作？

如果您問如何覆蓋您的應用程序主包中包含的plist，那麼您應該知道它無法完成。看看這個問題的更多細節：Can you update a file in the application bundle?

NSError *error; NSArray *paths =  
NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *docDirPath = [documentsDirectory stringByAppendingPathComponent:@"TitleArray.plist"]; 
NSFileManager *fileManager = [NSFileManager defaultManager]; 
if(![fileManager fileExistsAtPath: docDirPath]) 
{  
    docDirPath = [[NSBundle mainBundle] pathForResource:@"TitleArray" ofType:@"plist"]; 
} 
NSMutableArray *tmpArray = [[[NSMutableArray alloc] initWithContentsOfFile: docDirPath] mutableCopy];
