Copy UITextField string to UITextView - ios

Question

How Can I copy UITextField string to UITextView?
I want to do it when UIButton;
[myUIButton addTarget:self action:#selector(touchButton) forControlEvents:UIControlEventTouchUpInside];
UITextField* textField (initialized, omit code here)
[self.view addSubview:textField];
//save string to the property
self.textFieldString = textField.text;
//textFieldString is #property NSString* textFieldString; at the header.
UITextView* textView (initialized, omit code here)
[self.textView setEditable:false];
[self.view addSubview:self.textView];
//here i want to implement UITextField string -> UITextView display
-(void)submitButtonClicked {
//....
//Problem i am having here is that, I can not see instance variable other than #property variable. How should I pass UITextField .text to UITextView?
}

Answer 1

Prepare the identifier to each UI
[textField setTag:100];
[self.view addSubview:textField];
[textView setTag:200];
[self.view addSubview:textView];
Identify the each UI element and Manage
-(void)submitButtonClicked {
//Problem i am having here is that,
// I can not see instance variable other than #property variable.
// How should I pass UITextField .text to UITextView?
UITextField *myTextField=(UITextField*)[self.view viewWithTag:100];
UITextView *myTextView=(UITextView*)[self.view viewWithTag:200];
myTextView.text=myTextField.text;
}

If you are creating UITextView programatically then create a property variable and synthesize the same. You can access the same using the synthesized name and in UIButton action method get the text and set it to UITextView.
In .m file you can declare UITextView as
#interface classname () {
UITextView *textView
}
or in .h file
#property (nonatomic, strong) UITextView *textView;
As you have described the problem 'Problem i am having here is that, I can not see instance variable other than #property variable. How should I pass UITextField .text to UITextView?'

In your button's action use:
textView.text=textField.text;
Declare your variables between #interface and #end and initialize them in the viewDidLoad. This way you'll be able to use them in your button's action.
#interface ViewController ()
{
UITextView *textView;
UITextField *textField;
}
#implementation ViewController
-(void) viewDidLoad
{
// Do the following
// Initialize both textView and textField
// Set their frames
// Add both of them as a subview to your view
}
#end
Now you'll be able to access both of them in your button's action.
Hope this helps.
