iOS如何重新加载tableview重新加载解析数组的数据？

Question

我是iOS中的新手，我有一个问题我解析了一个数组，并在表格中显示有三个部分，每个部分我添加了新行，将其所有子级别添加到层次结构中但由于表重新加载问题，其索引更改并显示错误的结果。这是我的代码

+ (void)getTypesWith:(void (^)(NSArray *, NSError *))completionHandler
{
    [ZNetworkManager postDataForBackGround:nil atURL:[ZMappingManager getRequestURLToGetPropertiesTypes] completionHandler:^(NSArray *array, NSError *error)
     {
         NSMutableArray *typesDictionariesArray =[NSMutableArray array];
         NSMutableDictionary* details = [NSMutableDictionary dictionary];
         if (!error)
         {
             NSDictionary *fetchedDictionary = (NSDictionary *) array;
             if([fetchedDictionary isKindOfClass:[NSDictionary class]] == NO)
             {
                 [details setValue:@"Fetched dictionary is null" forKey:@"desription"];
                 completionHandler(nil ,[NSError errorWithDomain:@"MyDomain" code:1 userInfo:details]);
             }
             else
             {
                 if([[[fetchedDictionary objectForKey:@"meta"] objectForKey:@"status"] isEqualToString:@"200"]){
                     NSDictionary *data = [fetchedDictionary objectForKey:@"response"];
                     if([data isKindOfClass:[NSDictionary class]] == NO)

}

的cellForRowAtIndexPath

if(selectionC == nil) { 
    selectionC=[[[NSBundle mainBundle] loadNibNamed:@"SelectionCell" owner:self options:nil] objectAtIndex:0]; 
} 
KLog(@"view frame is %@",NSStringFromCGRect(self.frame)); 
KLog(@"table frame is %@",NSStringFromCGRect(tableView.frame)); 
NSArray *values =[[ZGlobals getPropertTypeSectionsValues] objectAtIndex:indexPath.section]; 
ZZameenType *type =[values objectAtIndex:indexPath.row];
selectionC.selectionTitle.text = type.title;
selectionC.selectionTitle.textColor = [ZTheme cellValuesColorIPAD];
