如何查看 NSUserDefaults 的完整内容 [重复]

Question

我有一个应用程序，我将所有用户首选项存储在 NSUserDefaults 中。我希望能够（出于调试目的）查看 NSUserDefaults 文件的完整内容。

可以不提供每个密钥就完成吗？

Answer 1

Can it be done without providing each of the keys?

您可以使用NSUserDefaults 中的dictionaryRepresentation，如下例所示：-

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

编辑：-

当使用dictionaryRepresentation时，它会打印出用户默认的完整信息，包括在默认中添加的额外值。

以下是上述代码的输出。您还可以看到最后一个值，该值额外包含在用户默认值中：-
