DWTagList

Create a list of tags from an NSArray to be show in a view with customisable fonts, colors etc.

Installation

Simple copy over DWTagList.h and DWTagList.m into your project and make sure you have linked the framework QuartzCore.framework.

You may then add tags to your view by the following lines of code:

// Initalise and set the frame of the tag list
tagList = [[DWTagList alloc] initWithFrame:CGRectMake(20.0f, 70.0f, 280.0f, 300.0f)];

// Add the items to the array
NSArray *array = [[NSArray alloc] initWithObjects:@"Foo", @"Tag Label 1", @"Tag Label 2", @"Tag Label 3", @"Tag Label 4", @"Tag Label 5", nil];
[tagList setTags:array];

// Add the taglist to your UIView
[self.view addSubview:tagList];

Customisation

In DWTagList.m there are a number of customisable options to change the layout and the aesthetics of the tags:

#define CORNER_RADIUS 10.0f
#define LABEL_MARGIN 5.0f
#define BOTTOM_MARGIN 5.0f
#define FONT_SIZE 13.0f
#define HORIZONTAL_PADDING 7.0f
#define VERTICAL_PADDING 3.0f
#define BACKGROUND_COLOR [UIColor colorWithRed:0.93 green:0.93 blue:0.93 alpha:1.00]
#define TEXT_COLOR [UIColor blackColor]
#define TEXT_SHADOW_COLOR [UIColor whiteColor]
#define TEXT_SHADOW_OFFSET CGSizeMake(0.0f, 1.0f)
#define BORDER_COLOR [UIColor lightGrayColor].CGColor
#define BORDER_WIDTH 1.0f

NOTE: In the future, these will be added as methods that can be used to customise the tags after initialisation.
