使用Plist字典进行应用程序设置

Question

我希望能够在我的应用中使用plist进行设置。我想要一本字典“设置”保持我的数组，例如“调试”，“选项1”，选项2“等。我将如何访问”设置“下的”调试“数组。字典？

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *myPlistPath = [documentsDirectory stringByAppendingPathComponent:@"ProfileManager.plist"]; 
NSDictionary *plistDict = [[NSDictionary alloc] initWithContentsOfFile:myPlistPath]; 

swDebug.on = [plistDict objectForKey:@"Debug"];

的.plist

Answer 1

在您的示例中，Debug是一个字符串，而不是一个数组（这就是您在问题中所说的内容）。在任何一种情况下，问题是您正在访问错误的字典中的密钥。你有：

swDebug.on = [plistDict objectForKey:@"Debug"];

你需要：

swDebug.on = [[plistDict objectForKey:@"Settings"] objectForKey:@"Debug"];

由于设置是字典plist中的字典。
