Question

我的数组有以下数据。我想搜索电子邮件ID和密码文本字段是否与数组值匹配。如果它们匹配，则用户可以登录其他无效凭证消息被警告。请帮帮我。

    {
        EmailId="sarika@gmail.com";password=sarika;
    },
    {
        EmailId="kalyan@gmail.com";password=kalyan;
    },
    {
        EmailId="kalyan@gmail.com";password=kalyan;
    }
    )

Answer 1

try iterating through your array and find if username and password matches with the textfield data

For( NSDictionary *data in myArray)
{

    if([emailtextField.text isEqualtoString:[data objectForKey:@"EmailId"]] &&  [passwordtextField.text isEqualtoString:[data objectForKey:@"password"]]){

       //Login
      break;

   }
   else{
       // Not Logged in
   }

}

Answer 2

试试这个：

NSMutableDictionary *dict=[[NSMutableDictionary alloc]init];
[dict setValue:emailTextField.text forKey:@"email"];
[dict setValue:passwordTextField.text forKey:@"password"];
if([myarray containsObject:dict]){
        //login
 }else{
        //dont login
    }

Appify[542:11303] (
{
    EmailId="sarika@gmail.com";password=sarika;
},

{
    EmailId="kalyan@gmail.com";password=kalyan;
},

{
    EmailId="kalyan@gmail.com";password=kalyan;
}

)

密码不是nsstring类型，实际上是您的数据：

Appify[542:11303] (

{
    EmailId="sarika@gmail.com";password="sarika";
},

{
    EmailId="kalyan@gmail.com";password="kalyan";
},

{
    EmailId="kalyan@gmail.com";password="kalyan";
}

)
