Meine benutzerdefinierten Zellendaten verschwinden, wenn ich es wählen und blättern Sie es aus dem Bildschirm

Question

Wie der Titel schon sagt: Meine benutzerdefinierten Zellendaten verschwinden, wenn ich es wählen und blättern Sie es auf dem Bildschirm aus

Meine Liste gut bestückt ist aber Nach dem didSelectRowAtIndexPath und Scrollen aus dem Bildschirm werden keine Daten mehr angezeigt.

Sah verschiedene Beiträge im Internet, aber keine kamen zu meiner Situation, so hoffe ich, jemand kann eine Antwort finden.

Unten ist der Code für den cellForRowAtIndexPath und didSelectRowAtIndexPath.

Wenn mehr Code benötigt wird, bin ich glücklich zu teilen.

Vielen Dank im Voraus, D

Zusatzinfo OKI'll hier die configurecell Methode zeigen. Vielleicht sieht jemand, was ich

-(void)configureCell{ 

//appDelegate 
ironmaiden_appDelegate *appDelegate = (ironmaiden_appDelegate *)[[UIApplication sharedApplication] delegate]; 

/* 
    cell design comes from rootApp.rootTheme OR from parentScreen's JSON data if over-ridden 
    Scenarios: 
     a) Title NO Description. 
      In this case, the row-height is used for the label the text is centered. 
     b) Title + Description. 
      In this case, the "listTitleHeight" is used and the the difference between this and 
      the row-height becomes the height of the description label 

    IMPORTANT: The image with be center in the image box. This means if the image is larger than 
    the row height it will not look right. Scaling images in lists is memory intensive so we do 
    not do it. This means you should only use icons/images that are "smaller than the row height"

Entfernen Sie den Zustand bin fehlt: - if (Zelle == null) {

von cellForRowAtIndexPath Methode.

und legte auch eine Bedingung in derselben Methode cellForRowAtIndexPath

, dass, wenn (indexpath.row < [self.menuItems count]) {

// alle Fälle setzen hier

}
