I've a very strange problem with my app. It runs perfectly on all Devices (even on iPad) running iOS 6.0. And with iOS 6.0.1 it runs also as expected on iPhone and iPod. But on iPad with 6.0.1 it crashes.

It's a very simple Single-View Application with a webView. This is my ViewControler.m:

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController


- (void)viewDidLoad
{
    NSURL *url = [NSURL URLWithString:@"http://telefonecke.tumblr.com"];
    NSURLRequest *req = [NSURLRequest requestWithURL:url];
    [_webView loadRequest:req];

    [super viewDidLoad];

}

-(BOOL) webView:(UIWebView *)inWeb shouldStartLoadWithRequest:(NSURLRequest *)inRequest             navigationType:(UIWebViewNavigationType)inType {
if ( inType == UIWebViewNavigationTypeLinkClicked ) {
    [[UIApplication sharedApplication] openURL:[inRequest URL]];
    return NO;
}

return YES;
}

- (void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];

[_webView reload];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willEnterForeground) name:UIApplicationWillEnterForegroundNotification object:nil];
}

- (void)viewDidDisappear:(BOOL)animated{
[super viewDidDisappear:animated];

[[NSNotificationCenter defaultCenter] removeObserver:self         name:UIApplicationWillEnterForegroundNotification object:nil];
}

- (void)willEnterForeground {
    [_webView reload];
}

- (void)didReceiveMemoryWarning
{

    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

I actually don't know why it's not working, especially because it runs perfectly on iOS 6.0 and all other devices.

I'm thankful for every suggestion. Thanks in advance!

Edit: I also have a crash report, if it's helpful: click here for the crash report

您的应用程序调用0x84f4e是主要功能，因此无需担心。

所以加载主故事板时会发生异常。这就是您应该开始关注的地方，例如故事板是否是应用程序包的一部分等。
