The implementation of the 2016-1-10 gesture unlock Demo

One: To implement a custom view, the code in the. h,.m file is as follows:

#import <UIKit/UIKit.h>@class  zllockview; @protocol Zllockviewdelegate <nsobject>-(void) LockView: (Zllockview *) LockView didselectedpwd: (NSString *) PWD; @end @interface  IDdelegate; @end

Second: Implement the Proxy method in the controller, the code is as follows:
