IQLabelView

IQLabelView is used to add text overlay and resize and rotate it with single finger.

How to install it?

CocoaPods is the easiest way to install IQLabelView. Run pod search IQLabelView to search for the latest version. Then, copy and paste the pod line to your Podfile. Your podfile should look like:

platform :ios, '7.0'
pod 'IQLabelView', '~> X.Y.Z'

Finally, install it by running pod install.

If you don't use CocoaPods, just import IQLabelView/ folder with all the .m, .h, and .bundle files to your project.
