fetching textfield.text values from dynamically generated textfields

Question

I am new to world of Objective C I am generating dynamic textfields and trying to fetch .text value from each textfield on button press but the problem i am facing is only value in last textfield is fetched eg- if 3 dynamic textfeilds are generated and i enter values 1,2,3 in textfeilds respectively i want all these values but currently i am getting value from only last textfeild

the code i am trying is as below //this function generates dynamic textfeilds

      - (void)dynamicTextboxes {
            NSString *string = txt1.text;
           int Pointsvalue = [string intValue];
           int x;     
          for (x=0; x < Pointsvalue ; x++)
            {     
               txtFldFrame1 = [[UITextField alloc] initWithFrame:CGRectMake(100,60*x,120,45)];
               txtFldFrame1.borderStyle=UITextBorderStyleRoundedRect;
               txtFldFrame1.keyboardType=UIKeyboardTypeNumberPad;    

                [self.view addSubview:txtFldFrame1];
               ArrPut=[[NSMutableArray alloc]initWithObjects:txtFldFrame1, nil];      
       }

         }


       // function to Acess the values
           NSString *string = txt1.text;
          int Pointsvalue = [string intValue];
          int x;
          for (x=0; x < Pointsvalue ; x++)
          {
              NSString * values=txtFldFrame1.text;
              [ArrPut addObject:values];
                if(txtFldFrame1.text.length>0)
                {

                 ArrClick=[NSMutableArray array];
               [ArrClick addObjectsFromArray:ArrPut];
             }
            }
               NSLog(@"%@",ArrClick);

This line: ArrPut=[[NSMutableArray alloc]initWithObjects:txtFldFrame1, nil]; is the cause of your problem. Should be using addObjectAtIndex method of a mutable array. And make sure ArrPut was allocated elsewhere outside the loop. — user523234

NSString *string = txt1.text;
int Pointsvalue = [string intValue];
int x;
  ArrClick=[NSMutableArray array];
for (x=0; x < Pointsvalue ; x++)
{
    NSString * values=txtFldFrame1.text;
    [ArrPut addObject:values];
    UITextField *txtField = (UITextField *)[self.view viewWithTag:x];
    if(txtField.text.length>0)
    {


        [ArrClick addObjectsFromArray:ArrPut];
    }
}
NSLog(@"%@",ArrClick);

// function to Acess the values

NSString *string = txtField.text;

}
NSLog(@"%@",ArrClick);

Hey, UIView itself has the tagValue 0... So, loop it from 1... Just check now
