[ios仿系列]仿支付宝手势解码

标签：ios   ios开发   ios仿支付宝手势   ios仿支付宝手势解锁   ios手势解锁   

呀~，这么快就转到ios阵营了？？？，android还有那么多坑呢？？？为此我也只能啃着馒头留下屈辱的眼泪了。。

本次由于开发公司产品的android版，继而ios版也负责一部分，其中一部分就是手势解锁的问题（为了要与android版一致，也算是非了一部分心血）

然而，但我打开iPhone，发现支付宝客户端已经没有手势解锁了，取而代之的时指纹解锁，关于指纹解锁，暂时还来不及研究，只能以后有机会再说了。。。

当然，支付宝android目前还是手势解锁，所以也是为了与之对应（ios版现在只能借鉴其android版了）

不多说了。。。。

1.资源

https://github.com/nsdictionary/CoreLock

上面的连接是一位大神已经写好的一个高仿支付宝手势解锁的项目，本来也可以说完全不用看我这篇文章就直接拿去用了，然而有些地方还是要改动一下的，毕竟是高仿嘛

此次具体的目的，如果你有android版支付宝客户端，请到‘手势’这一功能看一看效果。

效果：

1.手势未开启时的界面：

2.点击滑块后的跳转界面：

3.第一次绘制结束后的界面（由于线条消失的比较快，并没有截到）：

4.两次绘制完成之后的界面：

看到这里如果你发现跟你的应用场景并不相同，下面的可以不用看了。

另，本文也不会提供代码下载，因为只是在这位大神的代码基础上做了自己的改动而已。

关于手势密码这一界面的设计，这里也不做提供，提供思路：

1.判断本地手势密码是否开启，根据开启标志，返回tableview的不同section和row，用以隐藏和显示界面中的各元素

2.手势密码的滑块和修改手势密码的点击，可以设置不同的标志，在跳转后的界面中进行判断来显示不同的东西。

顺序：

手势密码界面->点击滑块或修改手势密码（没有设置情况下是隐藏）->设置手势密码界面

设置手势密码这一个界面，我是在storyboard中拉了一个viewcontroller来搞的，如果你有其他方法都行，下面是这个界面的主要代码：

回到，上面的代码中，可以看到，头部引入了很多东西，由于是完整的内容，这里对于我来说都是必须的，这里讲解一下

"CommonData.h"  这个类（不可少，下面的其他类暂时都可以不要）主要做数据共享，主要是判断setFlag的标志显示不同的界面内容的，可以看到主要有，0，1，2三个标志，0代表未设置手势密码，这种情况下要绘制2次，1，代表的时设置过手势密码，但是要关闭这个手势，这是就要验证手势，见下图：

2代表的是，点击修改的标志，这个逻辑是先验证，然后在重新绘制新的手势，这个过程有3步，主要验证->绘制第一次->绘制第二次。

"SWProperties.h" 主要是我的本地sqlitedb的操作，用于保存手势密码设置未设置的标志，这里不做详细说明，如果你不保存可以不需要

"SWTool.h" 主要是一些工具类，这里主要用到 空字符串的判断，请自己查找

"TextDialog.h"是点击验证登录密码时的弹出框，请自己找，效果：

"MBProgressHUD.h"这个不用说了吧，验证的时候肯定要花费时间的，一个等待的提示，不可少

"SWCallWebservice.h"封装的验证登录密码的类

"RetCodeMessageBean.h"验证登录返回后的对象

由于我没有把demo中的 CLLockVC相关类copy过来，所以有些改动，首先把：

typedef enum{
    
    //设置密码
    CoreLockTypeSetPwd=0,
    
    //输入并验证密码
    CoreLockTypeVeryfiPwd,
    
    //修改密码
    CoreLockTypeModifyPwd,
    
}CoreLockType;

@property (nonatomic,assign) BOOL needLine;

再把这个类中的方法添加一个参数

@property (nonatomic,copy) void (^setPWFirstRightBlock)(NSString *pwd);

if(_setPWFirstRightBlock != nil) _setPWFirstRightBlock(self.pwdM);

-(void)itemHandel:(CLLockItemView *)itemView{
    
    //选中
    if(self.needLine){
        itemView.selected = YES;
    }else{
        itemView.selected = NO;
    }
    itemView.need = self.needLine;
    //绘制
    [self setNeedsDisplay];
}

修改 CLLockInfoView.h

@property (nonatomic,assign) BOOL success;
@property (nonatomic,copy) NSString  *pwd;

这个主要是用于绘制的时候，头部的小图标里面的小圆圈也对应改变而已。

    //绘制路径
    CGContextStrokePath(ctx);
    
    //释放路径
    CGPathRelease(pathM);
}

到此，对于demo的修改已基本结束，不得不说，这位大神的demo非常强大

下面是关于如何启动或跳转到手势解锁界面的

说明一下，我的启动画面是自己做的，并没有用系统提供的launchScreen

所以，登录跳转还是比较方便，在启动画面的controller里面判断如果设置了手势，就跳转到手势登录界面，手势登录效果图：

代码也很简单，在storyboard中拉一个viewcontroller，选择好我们的手势登录类就行了：

代码相对较少，相信大家经过设置手势功能后，这里也肯定没问题。

最后是其他跳转了，

现在的主要逻辑是，app缓存到后台之后5分钟，我就会跳转到手势锁屏，其他情况，暂时没考虑。

所以我在AppDelegate.m中的applicationDidEnterBackground和applicationWillEnterForeground中做了简单的事情，代码如下：

- (void)applicationDidEnterBackground:(UIApplication *)application {
    NSLog(@"mark3");
    NSDate* date = [NSDate dateWithTimeIntervalSinceNow:0];
    NSString *isShowed = [prop getValuebyFieldName:@"pub.gestureShowed"];
    if([SWTool isEmptyString:isShowed]||[isShowed isEqualToString:@"0"]){
        timer=[date timeIntervalSince1970];
    }
}

- (void)applicationWillEnterForeground:(UIApplication *)application {
    NSString *gesturePwd = [prop getValuebyFieldName:@"gesturePwd"];
    NSString *gestureFlag = [prop getValuebyFieldName:@"gestureFlag"];
    NSString *token = [prop getValuebyFieldName:@"devicetoken"];
    
    if(![SWTool isEmptyString:token]&&![SWTool isEmptyString:gesturePwd]&&![SWTool isEmptyString:gestureFlag]&&[gestureFlag isEqualToString:@"1"]){
        NSString *isShowed = [prop getValuebyFieldName:@"pub.gestureShowed"];
        if([SWTool isEmptyString:isShowed]||[isShowed isEqualToString:@"0"]){
            NSDate* dat = [NSDate dateWithTimeIntervalSinceNow:0];
            if(!timer){
                timer=[dat timeIntervalSince1970];
            }
            NSTimeInterval temp = [dat timeIntervalSince1970];
            if((temp-timer)>300){
                UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
                GestureLoginViewController *gestureLoginViewController = (GestureLoginViewController*)[storyboard instantiateViewControllerWithIdentifier:@"gestureLogin"];
                [CommonData shareInstance].needFinish = YES;
                [prop writeValueByFieldName:@"pub.gestureShowed" withValue:@"1"];
               
                UIViewController *topRootViewController = [UIApplication sharedApplication].keyWindow.rootViewController;
                while (topRootViewController.presentedViewController)
                {
                    topRootViewController = topRootViewController.presentedViewController;
                }
                [topRootViewController presentViewController:gestureLoginViewController animated:YES completion:nil];
            }
        }
        
    }
}

applicationDidEnterBackground中记录时间，applicationWillEnterForeground根据时间显示手势界面，当然，这里面也有判断是否设置手势，是否已经跳转到手势了等等。

至此，已经完结了，哦对了，手势还有点bug，我发现滑动的适合，两个点之间我稍微的从外面绕一下，就导致中间的点没连上，真是郁闷啊，由于时间比较冲忙，后面我肯定也要解决这个问题的，不过，会不会写下来，就不知道了，提供一下思路，上一个点与下一个点取中间的坐标，判断这个坐标里面是否有按钮，有的情况，判断是否已经添加，没有就加进去。

由于是第一次做ios，而且还是在地铁上花了一个星期不到的时间看着电子书学习ios，然后用1个月的时间完成公司的产品，前面也说过，我是做的android版，然后对应的ios版，也是我来做，时间非常的仓促，很多的地方也有不懂之处，代码写的也比较乱，希望大家不要鄙视。。。。

嘛，就这样愉快的做ios吧，啦啦啦~~~~~~
