TIToken's now support a 'flat design' that does not add a gradient to the main body of the token. To use implement: - (BOOL)tokenField: willAddToken: And set your token's tint color and set flat design to YES.
When a flat design token is selected / highlighted the color of the selected state is made either slightly darker or slightly brighter. This is determined based of whether or not the color is a 'dark' color or if it is a 'light' color. A weighted distance of the RGB color space is computed and if the color is greater than 127.5 it is darker. Weighted RGB Brightness formula: brightness=sqrt( .241*R^2 + .691*G^2 + .068*B^2) Added TIToken private methods: - (UIColor *)lighterColorForColor:(UIColor *)c; - (UIColor *)darkerColorForColor:(UIColor *)c; - (BOOL)isColorDarker:(UIColor *)color;

In TIToken's drawRect: method I'm pretty sure I segregated all the gradient color setting correctly. Well, The results sure look right. But let me know if I may have messed that up and I can fix it. |
Useful if you need to know when a token is being highlighted. For my use case this was useful because of a 'tap to dismiss' checks to see if a token is being highlighted and if it is then it won't dismiss the tokenfield from being the first responder.

In this PR I've added support for flat color tokens (i.e no gradients). When the token is selected/highlighted the color is adjusted to be either slightly lighter or darker dependent on a weighted brightness of the token's tintcolor. See the image below for an example.
For those who don't know, you can adjust your token's tintColor in the following delegate:
I also added the podspec file as this is fairly standard across pods to have it in the repo. (I would say at least 90% of the pods I've used / looked at have it this way)
