Dynamiclly creating View in iOS - iphone

Question

I have a project with one View. I'm drawing everything on it programically. So when i want to add another View (screen) to my project i create a class inherits from the UIViewController class and implements method
- (void)viewDidLoad
And then i want to load this View from my original View, and i do this:
In ViewController.h
#import <UIKit/UIKit.h>
#import "TestViewControllerClass.h"
#interface ViewController : UIViewController <UITableViewDataSource> {
}
#property (strong,nonatomic) TestViewControllerClass *testView;
#end
In ViewController.m
#implementation ViewController
#synthesize testView;
- (void)viewDidLoad
{
[super viewDidLoad];
testView = [[TestViewControllerClass alloc] init];
[self.view addSubview:testView]; //crash here
}
And then in my TestViewControllerClass.h
#import <UIKit/UIKit.h>
#interface TestViewControllerClass : UIViewController
#end
And TestViewControllerClass.m
- (void)viewDidLoad
{
[super viewDidLoad];
}
To check if method wiewDidLoad will be executed i put there a breakpoint, but nothing happend. In fact, my app crash (I put comment at code where).
When crashes i receive: -[TestViewControllerClass superview]: unrecognized selector sent to instance 0x683aca0

Answer 1

Replace
[self.view addSubview:testView]; //crash here
with
[self.view addSubview:testView.view];

Answer 2

Use this code...
[self.view addSubview:testView.view];
Hope,this will help you...

Answer 3

What you're doing is settings your ViewController as the view, not the real view
testView = [[TestViewControllerClass alloc] init];
[self.view addSubview:testView]; //crash here
this will obviously crash. Assuming you have a view variable declared in your header file called view, use
testView = [[TestViewControllerClass alloc] init];
[self.view addSubview:testView.view];

You can load two types for uiviewcontroller loading below:
[self.view addSubview:testView.view];
(or)
use presentmodalviewcontroller below code:
testView *popupView = [[testView alloc] initWithNibName:#"testView" bundle:nil];
popupView.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentModalViewController:popupView animated:YES];
dimiss modal view cntroller below code:
[self dismissModalViewControllerAnimated:YES];
