ios 6 presentViewController

Question

在presentViewController中，定位不起作用。甚至我也在为UINavigationController使用分类。调用supportedInterfaceOrientations方法，但不进行任何更改。在Base中，shouldAutorotate方法返回YES。有以下代码的地方。

我正在使用这段代码.

ViewControllerOne *viewOne = [[ViewControllerOne alloc]init];

UINavigationController *navCtrl = [[UINavigationController alloc] initWithRootViewController:viewOne];
navCtrl.modalPresentationStyle = UIModalPresentationFormSheet;

[self presentViewController:navCtrl animated:YES completion:nil];

请帮帮我。提前谢谢..。

Answer 1

您使用的是哪个模拟器ios 5或ios 6？再发些代码。还可以看到这个link.

替换了appDelegate中的一行代码：

[window addSubview:viewController.view];

按照这一行：

[window setRootViewController:viewController];

检查iOS 5和6

if ([self respondsToSelector:@selector(presentViewController:animated:completion:)])
        {
            [self presentViewController:navigationControllerCustom animated:YES completion:nil];
        }
        else
        {
            [self presentModalViewController:navigationControllerCustom animated:YES];
        }

试着使用旋转

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
    return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}
