ios - 我的字典是空的，尽管它有值

Question

我有一个非常奇怪的问题我有这些值的字典

NSDictionary * dic = [NSDictionary dictionaryWithObjectsAndKeys:@"1",@"usr_id",areaChoosedId,@"usr_adrs", _username.text ,@"usr_psd", _name.text ,@"usr_name",_mobile.text,@"usr_tel",_email.text,@"usr_mail",_password.text,@"usr_pwd",usr_ava,@"usr_ava", nil];

但是当我打印字典时它会输出

{
    "usr_id" = 1;
}

虽然当我打印用户名或手机或电子邮件时都有值而不是 nil 那么问题是什么？

使用这个。您似乎没有获得 areaChoosedId 的值。

NSMutableDictionary * dic = [[NSMutableDictionary alloc] init];
     [dic setObject:@"1" forKey:@"usr_id"];
     [dic setObject:areaChoosedId forKey:@"usr_adrs"];
     [dic setObject:_username.text forKey:@"usr_psd"];
     [dic setObject: _name.text forKey:@"usr_name"];
     [dic setObject: _mobile.text forKey:@"usr_tel"];
     [dic setObject: _email.text forKey:@"usr_mail"];
     [dic setObject: _password.text forKey:@"usr_pwd"];
     [dic setObject: usr_ava forKey:@"usr_ava"];

希望它对你有用。
