"String" is not convertible to "String?"
I get an error in my title - "String" is not convertible to "String?" on this line:

let alertController = PCLBlurEffectAlert.Controller(title: "Uh-Oh!", message: error?.localizedDescription, effect: UIBlurEffect, style: .alert)

Would be glad to hear any of your ideas, tried to attach a screenshot here, but GitHub experiences some problems...

trouble setting buttonTextColor

My code is:

let alert = PCLBlurEffectAlertController(title: title, message: message, effect: UIBlurEffect(style: .extraLight), style: .alert)

alert.configure(buttonFont: UIFont.systemFont(ofSize: 24), buttonTextColor: Constant.SLS_SECONDARY_COLOR, buttonDisableTextColor: Constant.SLS_DISABLED_COLOR)

Getting error on the highlighted part that says, Cannot convert value of type 'UIFont' to expected argument type '[PCLBlurEffectAlert.ActionStyle : UIFont]?'

Please help, I don't understand what this error means or how to fix.

毛玻璃

你好，愿不愿意跟我一起探讨一下对话框的毛玻璃问题呢？因为我发现无论是系统，还是微信，微博等，它们的毛玻璃都很漂亮。我说的漂亮是什么意思呢，意思就是毛玻璃不会受到蒙板的影响，我看你的蒙板设置的alpha值是0.3，其实0.3过低了，系统设置的是黑色0.4透明，我看过系统的层级关系图，毛玻璃并未受到蒙板的任何影响，我自己最近也封装了一个https://github.com/SPStore/SPAlertController。但是不管我怎么设置毛玻璃，因为蒙层的影响，都会偏黑色，我看你的也同样如此。这个问题我已经想了几天几夜了，网上找资料也没人解决过，其实用第三方不是不能实现，但是我不想依赖第三方，而且系统用的也是iOS8自带的UIBlurEffect，只是我不知道系统是如何做到的，我想过用运行时去交换UIVisualEffectView的某个方法，但那么多私有方法，我也不知该重写哪一个。微信微博和系统的毛玻璃效果都是一致的，能否一起研究一下，我实在遇到困难了。
