IOS6.0 控制器展现方式总结

1. modal a controller

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];

ControllerA *ca = [storyboard instantiateViewControllerWithIdentifier:@"ControllerA"];

UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:ca];

ca.modalPresentationStyle = UIModalPresentationFullScreen; // 全屏视图显示

ca.modalTransitionStyle = UIModalTransitionStyleCoverVertical; // 从下向上滑出

// modal

[self presentViewController:nav animated:YES completion:NULL];

2. dismiss a modal controller

[self dismissViewControllerAnimated:YES completion:NULL];

3. push a controller

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];

ControllerA *ca = [storyboard instantiateViewControllerWithIdentifier:@"ControllerA"];

// push

[self.parentViewController.navigationController pushViewController:ca animated:YES];

4. pop a controller

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];

ControllerA *ca = [storyboard instantiateViewControllerWithIdentifier:@"ControllerA"];

UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:ca];

popover.popoverContentSize = CGSizeMake(320, 480);

// pop

[popover presentPopoverFromBarButtonItem:item

permittedArrowDirections:UIPopoverArrowDirectionAny

animated:YES];

5. dismiss a pop controller

[self.popover dismissPopoverAnimated:YES];
