Question

I am using the below statement to define the transitionstyle

_viewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; 

in the below code but the above statement is not flipping horizontally while presenting it modally

@property (nonatomic, assign) UIModalTransitionStyle *modalTransitionStyle;
@synthesize modalTransitionStyle; 


self.view = [[[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]]autorelease];

[self.view setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];

_viewController = [[ModalViewController alloc] init];

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:_viewController];

UIBarButtonItem * button = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:    UIBarButtonSystemItemDone target:self action:@selector(dismissView:)] autorelease];

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:_viewController];

UIBarButtonItem * button = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:    UIBarButtonSystemItemDone target:self action:@selector(dismissView:)] autorelease];

[_viewController.navigationItem setLeftBarButtonItem:button animated:YES];

navigationController.navigationBar.tintColor = [UIColor brownColor];

_viewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;

[self.navigationController presentModalViewController:_viewController animated:YES];

Anyone knows that why it is so. When everthing is coded programmtically.

Thanks for help though.

Wrong way to approach the problem. I suggest you to review your code in order to improve readability and maintainability.

Supposing that you’ve a viewcontroller with a target action associated with a button, something like this:

...
[aButton addTarget:self 
            action:@selector(dismissView:) 
  forControlEvents:UIControlEventTouchUpInside];
...

You can write a selector method, in order to display your new viewcontroller as follow:

- (void)dismissView:(id)sender {
    SecondViewController *secondVC = [[SecondViewController alloc] init];
    secondVC.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; 
    [self presentModalViewController:secondVC animated:YES];
    [secondVC release];
}
