UITextField in ScrollView doesnt display keyboard in iOS

Question

I have 10 textfield in a UIView, and I have added the view to a scrollView. In that 5 textFields will be displayed, and other will be scrolled.

In my textFieldDidBeginEditing

-(void)textFieldDidBeginEditing:(UITextField *)textField
{
    if (textField.tag>=4)
    {
        CGRect viewframe=contentsOfView.frame;
        viewframe.origin.y=viewframe.origin.y-100;
        contentsOfView.frame=viewframe;

    }
}

And in my textFieldDidEndEditing

-(void)textFieldDidEndEditing:(UITextField *)textField
{

    if(textField.tag>=4)
    {
        CGRect viewframe=contentsOfView.frame;
        viewframe.origin.y=viewframe.origin.y+100;
        contentsOfView.frame=viewframe;
    }

}

The first 5 fields which are getting displayed in the screen works perfectly, if I scroll the screen for the next text field. If I tap in it, the keyboard doesnt appears.

[contentsOfView addSubview:nameField];
[contentsOfView addSubview:mobileNumberField];
[contentsOfView addSubview:passwordField];
[contentsOfView addSubview:taxiNumberfield];
[contentsOfView addSubview:emailIdField];
[contentsOfView addSubview:taxiTypeField];
[contentsOfView addSubview:licenseNumber];
[contentsOfView addSubview:nricNumber];
[contentsOfView addSubview:noOfPassengerField];
[contentsOfScrollView addSubview:contentsOfView];
 [self.view addSubView:contentScrollView ];

TextField

 nameField.borderStyle=UITextBorderStyleLine;
nameField.layer.borderWidth=1.0;
nameField.layer.borderColor=[[HexColorCode colorWithHexastring:@"c88202" ] CGColor];
nameField.keyboardType=UIKeyboardTypeNamePhonePad;
nameField.placeholder=@"NAME";
nameField.backgroundColor=[UIColor whiteColor];
 UIView *  paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 15, 20)];
nameField.leftView = paddingView;
nameField.leftViewMode = UITextFieldViewModeAlways;
nameField.contentVerticalAlignment=UIControlContentVerticalAlignmentCenter;
nameField.delegate=self;
nameField.tag=1;
