代码:

BOOL displayedNativeDialog = [FBNativeDialogs presentShareDialogModallyFrom:self initialText:@"NeeemuG - Veja meu look." image:nil url:[NSURL URLWithString:@"https://www.neemu.com"] handler:^(FBNativeDialogResult result, NSError *error) {

        // Only show the error if it is not due to the dialog
        // not being supporte, i.e. code = 7, otherwise ignore
        // because our fallback will show the share view controller.
        if (error && [error code] == 7) {
            return;
        }

        NSString *alertText = @"";
        if (error) {
            alertText = [NSString stringWithFormat:
                         @"error: domain = %@, code = %d",
                         error.domain, error.code];
        } else if (result == FBNativeDialogResultSucceeded) {
            alertText = @"Posted successfully.";
        }
        if (![alertText isEqualToString:@""]) {
            // Show the result in an alert
            [[[UIAlertView alloc] initWithTitle:@"Result"
                                        message:alertText
                                       delegate:self
                              cancelButtonTitle:@"OK!"
                              otherButtonTitles:nil]
             show];
        }
    }];

    // Fallback, show the view controller that will post using me/feed
    if (!displayedNativeDialog) {
        NSLog(@"No IOS6.");
    }

在我的委托(delegate)中，我将 [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"background"]] 放入背景导航栏，我不知道为什么会崩溃，但是当我删除解析时 问题所在。
