アプリに問題があります。
マルチタスク用のホーム ボタンを使用して別のアプリに移動するとクラッシュし、もう一度アプリに戻りたいときにクラッシュし、次のメッセージが表示されます。 

*** -[UIView convertRect:toView:]: message sent to deallocated instance 0x81e4020

「インナービュー」広告を実装してから始まりました。
コードを消すためにコードで何かをする必要がありますか?
私はそれを解決しようとしましたが、成功しませんでした。
これは私の広告のコードです: 

    CGRect frame = CGRectMake(0, 480, 320, 50);
    self.adBanner = [[UIView alloc] initWithFrame:frame];
    [self.view convertRect:adBanner.frame toView:nil];   --->This is a line i tried to put...
    [self.view addSubview:self.adBanner];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(iaAdReceived:) name:@"iaAdReceived" object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(iaDefaultAdReceived:) name:@"iaDefaultAdReceived" object:nil];

    - (IBAction)iaAppShouldSuspend:(id)sender
    {
        // The app should suspend (for example, when the ad expands)
    }

    - (IBAction)iaAppShouldResume:(id)sender
    {
        // The app should resume (for example, when the ad collapses)
    }

何が原因でしょうか?

あなたの問題は、実行時：

[self.view convertRect:adBanner.frame toView:nil];

あなたのビューはもう存在しません。

appDelegate では、このメソッドに取り組む必要があります:

- (void)applicationDidBecomeActive:(UIApplication *)application
{
/*
 Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
 */
}

とにかく、この行で何を達成しようとしましたか? 使用していない CGRect を返しているためです。
