寫入到PhoneGap的Cordova.plist文件會導致錯誤

Question

我加入以下到我的Cordova.plist文件：

Key: EnableEverything 
Type: Boolean 
Value: YES 

然後我用下面的代碼讀取和寫入plist文件：

NSString *adKey = @"EnableEverything"; 

NSString *pathToSettingsInBundle = [[NSBundle mainBundle] pathForResource:@"Cordova" ofType:@"plist"]; 
NSMutableDictionary *plist = [NSDictionary dictionaryWithContentsOfFile: pathToSettingsInBundle]; 

NSString *enableEverything = [[plist valueForKey:adKey] stringValue]; 
NSLog(@"EnableEverything: %@", enableEverything); // this returns 1, which is correct. 

// Disable in plist. 
[plist setValue:NO forKey:adKey]; 
[plist writeToFile:pathToSettingsInBundle atomically:YES]; 

NSLog(@"EnableEverything: %@", enableEverything); // never reaches this line 

我得到以下錯誤：

2012-09-07 14:20:12.168 slq[958:707] *** WebKit discarded an uncaught exception in the webView:decidePolicyForNavigationAction:request:frame:decisionListener: delegate: <NSInternalInconsistencyException> -[__NSCFDictionary removeObjectForKey:]: mutating method sent to immutable object 

似乎有是一個問題，當它試圖寫入文件。

您正在更改應用程序包中的文件。這是蘋果禁止的。選中此項：writing NSDictionary to plist in my app bundle

您必須將plist複製到允許更改的文件夾中，例如Douments文件夾。
