我有一个应用程序，我将所有用户首选项存储在NSUserDefaults中。我希望能够看到（出于调试目的）NSUserDefaults文件的完整内容。
可以在不提供每个密钥的情况下完成吗？
答案 0 :(得分：2)
Can it be done without providing each of the keys?
您可以使用NSUserDefaults的{{3}}，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： -
使用dictionaryRepresentation时，它会打印用户默认的完整信息，包括默认值中添加的额外值。
以下是上述代码的输出。您还可以在最后一个中看到用户默认值中额外包含的值： -
