人们都在询问如何在Uitableview中添加图像.好吧,我想要相反,我怎样才能缩短细胞并在它前面添加图像？就像whatsapp-group-info-screen一样.(见图)

我正在使用此代码在我的tableview中搜索:

for (Actor *actorz in arr)
{     
     NSComparisonResult result = [actorz.actorNaam compare:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:[actorz.actorNaam rangeOfString:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch)]];
     if (result == NSOrderedSame)
     {
          [self.filteredListContent addObject:actorz];
     }   
}

现在我想知道如何不仅可以将searchText与actorz.actorNaam进行比较,还可以将其与actorz.actorBeschrijving进行比较？所以我想将searchText与两个字符串进行比较..

我想保存目标和演员.这两个实体与责任关系相关:

Goal *addgoal = (Goal*)[NSEntityDescription insertNewObjectForEntityForName:@"Goal" inManagedObjectContext:context];

    addgoal.goalNaam = nameTextField.text;
    addgoal.goalId = idField.text;
    addgoal.goalBeschrijving = beschrijvingField.text;

    Actor *addactor = (Actor*)[NSEntityDescription insertNewObjectForEntityForName:@"Actor" inManagedObjectContext:context];

    addactor.actorNaam = responsibleField.text;

    [addgoal addResponsibilityObject:addactor];

上面的行([addgoal addResponsibility:addactor])导致错误,有什么问题？

在Goal.h中:

@interface Goal (CoreDataGeneratedAccessors)
- (void)addResponsibilityObject:(Actor *)value;
@end

错误:
