Zeigen Sie den Code an, den Sie versucht haben. Sie können Schaltflächen verwenden, die zwei Bilder für den ausgewählten und den Standardstatus festgelegt haben, und dann das Bild entsprechend verwalten. –

möchten Sie Benutzern erlauben, Rate zu geben oder wollen nur Bewertung zeigen? – ivarun

Hi ivarun, Ja. Ich möchte Benutzern erlauben, eine Bewertung abzugeben. –

Ich würde Ihnen empfehlen, diese selbst nur zu tun, wenn Sie in der Entwicklung neu sind und Sie möchten Ihre Logik bauen, so stattdessen jede vorgefertigte Bibliothek verwenden, können Sie unter Schritte folgen.

Erste hinzufügen 5 Tasten auf der Zelle und Set grenzte Stern für jeden Zustand Standardtasten und dann Tasten Zustand zu ausgewähltem ändern und Set Sternbild gefüllt. (Tun Sie dasselbe für 5 Tasten). Nachdem Sie dies getan haben, stellen Sie sicher, dass Sie den Status aller Schaltflächen auf Standard setzen.
Aktion hinzufügen buttonStarRatingsClicked für alle 5 Tasten.
Erstellen Sie Outlet-Sammlung buttonCollectionStarRatings für jede Schaltfläche in starsInCell-Klasse.

Fügen Sie die untenstehende Methode in Ihrem ViewController hinzu, der tableView mit Sternen in jeder Zelle anzeigt.

- (IBAction)buttonStarRatingsClicked:(id)sender { 

UIButton *buttonStarRatings = (UIButton*) sender; 

//Here you will need to get cell to access buttonCollectionStarRatings 
UITableViewCell *cell = (UITableViewCell*) [[buttonStarRatings superView] superView]; 
//Check is clicked button is selected 
if ([buttonStarRatings isSelected]) { 


if (buttonStarRatings.tag == 0) { //Check is clicked button is first button 

    //Check if Next button of selected button is selected 
    if ([cell.buttonCollectionStarRatings[buttonStarRatings.tag+1] isSelected]) { 

     @autoreleasepool { 

      for (int i = (int)buttonStarRatings.tag+1; i < [cell.buttonCollectionStarRatings count]; i++) { 
       UIButton *buttonStarRating = cell.buttonCollectionStarRatings[i]; 
       [buttonStarRating setSelected:NO]; 
      } 
     } 

    } else { 
     //If selected button is first button and is selected then do not take any action as atlease one star should be selected. 
    } 

} else if (buttonStarRatings.tag == 4) { //Check is clicked button is last button 

    [buttonStarRatings setSelected:NO]; 

} else { //Selected button is one of the button between first and last 

    //Check if Next button of selected button is selected 
    if ([cell.buttonCollectionStarRatings[buttonStarRatings.tag+1] isSelected]) { 

     @autoreleasepool { 

      for (int i = (int)buttonStarRatings.tag; i < [cell.buttonCollectionStarRatings count]; i++) { 
       UIButton *buttonStarRating = cell.buttonCollectionStarRatings[i]; 
       [buttonStarRating setSelected:NO]; 
      } 
     } 
    } else { 
     [buttonStarRatings setSelected:NO]; 
    } 
} 
} else { 

if (buttonStarRatings.tag == 0) { //Check is clicked button is first button 

    [buttonStarRatings setSelected:YES]; 
} else if (buttonStarRatings.tag == 4) { //Check is clicked button is last button 

    @autoreleasepool { 

     for (UIButton *buttonStarRating in cell.buttonCollectionStarRatings) { 
      [buttonStarRating setSelected:YES]; 
     } 
    } 
} else { //Selected button is one of the button between first and last 

    @autoreleasepool { 

     for (int i = 0; i <= (int)buttonStarRatings.tag; i++) { 
      UIButton *buttonStarRating = cell.buttonCollectionStarRatings[i]; 
      [buttonStarRating setSelected:YES]; 
     } 
    } 
} 
} 
}

Der obige Teil Sie Sterne-Bewertungen auf jeder Zelle nächster Schritt wird die Verwaltung der ausgewählten Sterne in jeder Zelle auswählen kann, während die Tabelle zu scrollen.

So wenden Sie Bewertungssterne in UITableViewCells an
