Simple Tag List View Container in Swift

TagListView

When I tried to find something on github that displays words in their own cells, I couldn't find anything. This is why I made a view container for displaying tags. It serves a simple purpose so I elected not to let users implement delegate functions, insetad they can just call the built-in functions of the view container to add tags and reset the view.

Usage:

• Initialize the container with a frame for the container. Note that this is not the frame for an individual tag.

let listView = TagListView(frame: CGRectMake(0,0,100,200))

• Apperance

listView.hashtagsOffset:UIEdgeInsets = UIEdgeInsets(top: 10, left: 10, bottom: 0, right: 0)
listView.rowHeight:CGFloat = 40 //height of rows
listView.tagHorizontalPadding:CGFloat = 5.0 // padding between tags horizontally
listView.tagVerticalPadding:CGFloat = 5.0 // padding between tags vertically
listView.tagCombinedMargin:CGFloat = 10.0 // margin of left and right combined, text in tags are by default centered.

• Add Tags and their corresponding selector

listView.addTag("YOLO", target: self, tapAction: "tap:", longPressAction: "longPress:",backgroundColor: UIColor.whiteColor(),textColor: UIColor.blackColor()) 

• Remove Tags

listView.removeTagWithIndex() //Remove tag at a given index
listView.removeTagWithName() //Remove tag with a name
listView.removeMultipleTagsWithIndices(indexSet:Set<Int>) //Bulk Remove with a set of Indices.

• Reset View

listView.reset() //Clears the screen

Customization:

To customize the appearance of the label, you can just dive into the addTag() func to change however you want your UILabel to look like.

Known Issue:

This View Container still scrolls poorly when there are large volume of labels on screen, due to the fact that I did not implement some sort of a caching mechanism for the UIScrollView.
