##How to use implementation the GCTagListDataSource and call the public method reloadData

-(void)viewDidLoad {
	[super viewDidLoad];
	GCTagList* taglist = [[GCTagList alloc] initWithFrame:CGRectMake(0, 180, 320, 200)];
    taglist.firstRowLeftMargin = 80.f;
    taglist.dataSource = self;
    [self.view addSubview:taglist];
    [taglist reloadData];
}

- (NSInteger)numberOfTagLabelInTagList:(GCTagList *)tagList {
    return self.tagNames.count;
}

- (GCTagLabel*)tagList:(GCTagList *)tagList tagLabelAtIndex:(NSInteger)index {
    
    static NSString* identifier = @"TagLabelIdentifier";
    
    GCTagLabel* tag = [tagList dequeueReusableTagLabelWithIdentifier:identifier];
    if(!tag) {
        tag = [GCTagLabel tagLabelWithReuseIdentifier:identifier];
        tag.labelBackgroundColor = [UIColor colorWithRed:84/255.f green:164/255.f blue:222/255.f alpha:1.f];
    }
    
    [tag setLabelText:self.tagNames[index]
        accessoryType:GCTagLabelAccessoryCrossFont];
    
    return tag;
}

##GCTagListDelegate Protocol

/**
 * 在reloadData, 如果TagList的高度有改變, 這個Mehtod會被觸發.
 * after reloadData, if the height of TagList has changed, will call this method.
 */
- (void)tagList:(GCTagList *)taglist didChangedHeight:(CGFloat)newHeight;

/**
 * 當點選TagLabel, 這個Method會被觸發.
 * Tapped the TagLabel, will call this mehtod.
 */
- (void)tagList:(GCTagList *)taglist didSelectedLabelAtIndex:(NSInteger)index;

/**
 * 點擊TagLabel's accessoryButton, 這個Method會被觸發.
 * Tapped the TagLabel's accessoryButton, will call this mehtod.
 */
- (void)tagList:(GCTagList *)tagList accessoryButtonTappedAtIndex:(NSInteger)index;

/**
 * 如果有實作<GCTagLabelListDataSource>的maxNumberOfRowAtTagList, 且發生需省略後續的TagLabel時會被觸發.
 * if implement protocol <GCTagLabelListDataSource> method 'maxNumberOfRowAtTagList' 
 * and the taglist's rows is more than the maxRow, this method will be call.
 * 
 * @retVal NSString the text for the TagLabel of theMaxRow's last one.
 */
- (NSString*)tagList:(GCTagList *)tagList labelTextForGroupTagLabel:(NSInteger)interruptIndex;

##GCTagListDataSource Protocol

/**
 * 在TagList中有多少個TagLabel.
 * how many count for taglist to display.
 */
- (NSInteger)numberOfTagLabelInTagList:(GCTagList*)tagList;

/**
 * 在TagList中的TagLabel.
 * the taglabel At index in the taglist.
 */
- (GCTagLabel*)tagList:(GCTagList*)tagList tagLabelAtIndex:(NSInteger)index;

@optional
/**
 * TagList最多幾行.
 * the max row at taglist.
 */
- (NSInteger)maxNumberOfRowAtTagList:(GCTagList*)tagList;

/**
 * TagList最後一行的最後一個TagLabel(Group TagLabel)的AccessoryType.
 * accessory type of the group taglabel.
 */
- (GCTagLabelAccessoryType)accessoryTypeForGroupTagLabel;
