推荐答案

包括这一行,

[self.allBookMarks removeObjectAtIndex:indexPath.row];

编辑:

问题不在于reloadData,问题在于您没有更新数据源(self.allBookMarks)。将值更新为self.allBookMarks然后重新加载表格。

The problem is not with reloadData, the problem is that you are not updating your datasource (self.allBookMarks). Update the values into self.allBookMarks then reload the table.

编辑代码

-(void) tableView:(UITableView *)tableView
commitEditingStyle:(UITableViewCellEditingStyle)editingStyle 
forRowAtIndexPath:(NSIndexPath *)indexPath 
{
    [self.table beginUpdates];

  if (editingStyle == UITableViewCellEditingStyleDelete) 
  { 
    Hadits *delHadit = [self.allBookMarks objectAtIndex:indexPath.row];
    dbAccess *dbmethods = [[dbAccess alloc] init]; 
    NSInteger delHaditid = delHadit.haditid;
    [dbmethods deleteBookMark:delHaditid];
    self.allBookMarks = [dbMethods getAllBookMarks]; 
    [dbmethods release];    
  }
  [self.table reloadData];//its not working reload data...
  [table endUpdates];
}
