如何查看NSUserDefaults的完整內容

Question

我有一個應用程序，我將所有用戶首選項存儲在NSUserDefaults中。我希望能夠看到（出於調試目的）NSUserDefaults文件的完整內容。

可以在不提供每個密鑰的情況下完成嗎？

Answer 1

Can it be done without providing each of the keys? 

您可以使用NSUserDefaultsdictionaryRepresentation像下面的例子： -

NSUserDefaults *def=[NSUserDefaults standardUserDefaults]; 
[def setObject:@"test1" forKey:@"test1"]; 
[def setObject:@"test2" forKey:@"test2"]; 
NSLog(@"%@",[[NSUserDefaults standardUserDefaults]dictionaryRepresentation]); 

編輯： -

使用時dictionaryRepresentation將打印用戶默認設置的完整信息，包括加在默認值中添加的值。

以下是上述代碼的輸出。你也可以看到最後的值是多餘的包含在用戶的默認值中： -
