title: How to enable AQGridView edit mode?
body: <p>I am using AQGridView for my project. The problem I'm facing is that I'm not able to enable my gridView's edit mode. What I want is that whenever the edit button gets clicked, the delete icon should be shown on each cell, click the edit again button will make that edit mode disable.</p>
  
  <p>here are my codes which don't work except the first function:</p>
  
  <pre><code>- (void) handleEditModeChange:(NSNotification * ) note  
  {   
      if(self.gridView.isEditing)
      {
          [self.gridView setEditing:NO animated:YES];
                  NSLog(@"gridView edit mode");
      }
      else 
      {
  
          [self.gridView  setEditing:YES animated:YES];
          NSLog(@"gridView NOT edit mode");
      }
  
  }
  
  
  - (UITableViewCellEditingStyle)gridView:(AQGridView *) aGridView  editingStyleForRowAtIndex:(NSUInteger) index {
      NSLog(@"editing style");
  
      // Detemine if it's in editing mode
      if(self.gridView.isEditing) {
          return UITableViewCellEditingStyleDelete;
      }
      return UITableViewCellEditingStyleNone;
  }
  
  
  - (void) gridView:(AQGridView *) aGridView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle  
      forRowAtIndex:(NSUInteger) index {
  
      NSLog(@"editing");
  }
  
  - (BOOL)gridView:(AQGridView *) aGridView canEditRowAtIndex:(NSUInteger) index {
      NSLog(@"canEditRowAtIndex");
      return YES;
  }
  </code></pre>
  
  <p>These codes are in a view controller which comforms with AQGridViewDelegate, AQGridViewDataSource already.</p>
  
  <p>The first function above works fine but the second function does not get called for some reason.</p>
  
  <p>The datasource function like the one below works fine.</p>
  
  <pre><code>- (AQGridViewCell *) gridView: (AQGridView *) aGridView cellForItemAtIndex: (NSUInteger) index;
  </code></pre>
  
  <p>I am new beginner for this. Could some people please tell me if this is possiable or if I am doing something wrong?</p>
  
  <p>Any suggestion I appreciate.</p>
