I’ve just pushed some code to GitHub to easily visualise an image upload in Objective-C. Hope it could help some of you out and save you some time! The class can be easily customised via various setters to change the radius, colors, etc.
You can find the code on GitHub. If you have any requests, put them in the issues panel. I’ve tested as many scenarios as I could, but if you find any bugs, please post them as well!
ps: don’t let the name mislead you, it isn’t really sexy. I just wanted to see the effect on clicks 😉
