还是在swift入门，最近找了一个类似android Toast的控件UIView+Toast

然后我用Object-c里面可以使用

－ (void@H_301_22@)makeText:(UIView@H_301_22@ *) view Msg :(NSString@H_301_22@ *)toast{
    [view makeToast:toast];
}

但是在swift中，却找不到makeText的方法，然后我把OC的方法设置为静态方法，在Swift中再加一次extension

extension UIView@H_301_22@{
    //@H_301_22@在OC@H_301_22@中定义的扩展在swifty中找不到？
    func showToast(Msg@H_301_22@ :String@H_301_22@){
        OCconnector@H_301_22@.makeText(self@H_301_22@,msg:@H_301_22@ Msg@H_301_22@)
    }
}

然后swift中就找到这个方法了，可能这样做有问题，迟点再研究一下
