如何在两个uiview之间传递参数

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.
