iPhone Development - Using Data from another view

First view: consists of a textview(user input) & button(pressing on this button takes u to the second view)

Second View: consists of a label

i want the label t开发者_运维百科o display what the user wrote in the first view.

I think you are creating second view when buttonClick. Just pass the data of textView (textView.text) to constructor of second view. Then you can set data to the label in viewDidLoad() method.

Take this in .h file in SecondViewController

NSString *strUserInput;

Make below function in seconviewcontroller

-(void)setUserInput:(NSString *)strEntered{
    strUserInput=strEntered;
}

Now In first view controller do like this:

SecondViewControler *objSecond = [[SecondViewController] initwithNibName:@"secondview.xib" bundle:nil];

[objSecond setUserInput:txtUserInput.text];
[self.navigationController pushViewController:objSecond animated:YES];
[objSecond release];

Now, In secondViewController viewWillAppear Method write this.

-(void)viewWillAppear:(BOOL)animated{
      lblUserInput.text = strUserInput;
}

Please check spelling mistakes as I hand written this. Hope this help.

If you are not using navigationContoller then you can do something like this.

SecondViewControler *objSecond = [[SecondViewController] initwithNibName:@"secondview.xib" bundle:nil];
[objSecond setUserInput:txtUserInput.text];
[objSecond viewWillAppear:YES];
[self.view addSubview:objSecond];
[objSecond release];
