Ich habe ein Problem mit einem UIAlertView zeigt wiederholt die Quelle nicht finden

Question

Mein Problem ist dies, in der App, wenn ein Benutzer irgendwo nicht wichtig klickt ein AlertView ausgelöst wird, ist in Ordnung, ich kann den Aufruf zu dieser Ansicht finden, aber dann zeigt sich immer wieder leer und ich habe überall dort einen Haltepunkt platziert, wo ich einen Alarmruf sehe. Aber die Geisterwarnung bricht nirgendwohin. Ich habe keine Ahnung, wer sie wirft, es ist nur eine empfindsame Sichtweise.

Können Sie einige Tipps geben, wie Sie den Punkt festlegen können, an dem die Ansicht aufgerufen wird?

... kann es nicht fügen Sie alle

Answer 1

Überprüfen Sie Ihre Viewcontroller, der hat ein ualertviewdelegate.

1. Anmelden Ihre alertview.delegate

2. Ihre Superklasse eines Viewcontroller Überprüfen Sie, ob es nicht uialertviewdelegate Funktion nicht nennen.

3. Wenn es ein UIAlertController, überprüfen ViewWillAppear, ViewDidAppear, viewwilldisappear (Superklasse auch) und finden heraus, dass sie nicht nennen [Alertview show]

Answer 2

Sie den Inhalt Ihrer Alertview fangen kann, wenn es überhaupt keinen Inhalt hat, präsentiere es nicht!

Überprüfen Sie dazu die Nachricht, die Sie an die Methode übergeben, die die alertView darstellt.

Allerdings kann ich nicht finden, Ihre Methode showAreYouReadyToSubmitFormMsg.

Answer 3

Nur zu Testzwecken:

Subclass UIAlertView dh @interface MyAlertView : UIAlertView

ersetzen dann alle Instanzen UIAlertView von MyAlertView dh MyAlertView *someAlert = [[MyAlertView alloc] init.......];

außer Kraft setzen Dann

-(void)show { 

[super show]; 

//Your breakpoint here 

OR 

NSLog([NSThread callStackSymbols]); 
} 

Answer 4

Warum Sie Enum für Alertview nehmen ? machen Sie einfach Instanz von UIAlertView, wo es erforderlich ist, zu zeigen. Sie können eine Methode machen, in der Sie zwei String-Parameter Alertview Massage und Titel und Methode Alertview mit diesem Titel und Massage übergeben können.
