Question

I have to send parameters between two UIView. This is how I’m loading the second UIView from the first:

SingleViewController *single = [[SingleViewController alloc] initWithNibName:@"SingleViewController" bundle:nil];
[self.view addSubview:single.view];

How can i send some NSString to the other view?

Answer 1

If I understand you correctly, then I think you would send the NSString to the view controller (single) and not the view (single.view).
Two common ways to do this come to mind. Set up a property for SingleViewController class in it’s .h file using @property, and then either:
1. set the property like

single.somestring = @"this is a string";

or 2. Create a new init method for SingleViewController and pass it in that way.

   SingleViewController *single = [[SingleViewController alloc] initWithMyString:@"this is a string" withNibName:@"SingleViewController" bundle:nil];

where you have declared initWithMyString:withNibName:bundle: in your SingleViewController.h file and in it you call initWithNibName:bundle: for the parent class.
