[ios仿系列]仿支付宝手势解码

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

。

本次因为开发公司产品的android版，继而ios版也负责一部分。当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client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，临时还来不及研究，仅仅能以后有机会再说了。。

。

当然，支付宝android眼下还是手势解锁，所以也是为了与之相应（ios版如今仅仅能借鉴其android版了）

不多说了。

。。

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，本来也能够说全然不用看我这篇文章就直接拿去用了，然而有些地方还是要修改一下的。毕竟是高仿嘛

此次详细的目的，假设你有android版支付宝client，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（因为线条消失的比較快。并没有截到）：



4.两次绘制完毕之后的界面：



看到这里假设你发现跟你的应用场景并不同样。以下的能够不用看了。

另，本文也不会提供代码下载。由于仅仅是在这位大神的代码基础上做了自己的修改而已。

关于手势password这一界面的设计，这里也不做提供，提供思路：

1.推断本地手势password是否开启，依据开启标志。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password的滑块和改动手势password的点击。能够设置不同的标志，在跳转后的界面中进行推断来显示不同的东西。

顺序：

手势password界面->点击滑块或改动手势password（没有设置情况下是隐藏）->设置手势password界面

设置手势password这一个界面，我是在storyboard中拉了一个viewcontroller来搞的。假设你有其它方法都行。以下是这个界面的主要代码：

首先看到这段代码后，先别急，把上面连接中下载下来的代码导入到你的项目中。主要这些：

回到，上面的代码中，能够看到，头部引入了非常多东西，因为是完整的内容，这里对于我来说都是必须的，这里解说一下

"CommonData.h" 这个类（不可少，以下的其它类临时都能够不要）主要做数据共享，主要是推断setFlag的标志显示不同的界面内容的。能够看到主要有，0，1，2三个标志，0代表未设置手势password。这样的情况下要绘制2次，1，代表的时设置过手势password，可是要关闭这个手势，这是就要验证手势，见下图：



2代表的是，点击改动的标志，这个逻辑是先验证，然后在又一次绘制新的手势，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password设置未设置的标志，这里不做具体说明，假设你不保存能够不须要

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

"TextDialog.h"是点击验证登录password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password的类

"RetCodeMessageBean.h"验证登录返回后的对象

刚開始的时候不可能一下把全部功能都做出来。那些临时用不到的先凝视掉，然后慢慢加入。所以，假设你遇到各种编译只是，各种红叉请不要心急，一步一步来，把最基本的东西做了即可了。

因为我没有把demo中的 CLLockVC相关类copy过来，所以有些修改，首先把：

typedef enum{

//设置password
CoreLockTypeSetPwd=0,

//输入并验证password
CoreLockTypeVeryfiPwd,

//改动password
CoreLockTypeModifyPwd,

}CoreLockType;

定义的这些东西放到CLLockView.h类中，并在这个类中加入属性：

@property (nonatomic,assign) BOOL needLine;

这个主要相应显示手势轨迹的功能，当然。这个主要用在手势锁屏后才干看到，假设你不须要也能够去掉。

再把这个类中的方法加入一个參数

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

在把相应的CLLockView.m文件里找到以下这一句。并改动：

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

并改动当中的方法：

-(void)itemHandel:(CLLockItemView *)itemView{

//选中
if(self.needLine){
itemView.selected = YES;
}else{
itemView.selected = NO;
}
itemView.need = self.needLine;
//绘制
[self setNeedsDisplay];
}

主要是加了是否须要轨迹的推断

改动 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相应改变而已。

CGFloat marginV = 3.f;
CGFloat padding = 1.0f;
CGFloat rectWH = (rect.size.width - marginV * 2 - padding*2) / 3;

//加入圆形路径
for (NSUInteger i=0; i<9; i++) {

NSUInteger row = i % 3;
NSUInteger col = i / 3;

CGFloat rectX = (rectWH + marginV) * row + padding;

CGFloat rectY = (rectWH + marginV) * col + padding;

CGRect rect = CGRectMake(rectX, rectY, rectWH, rectWH);
if(success&&pwd){
if ([pwd rangeOfString:[NSString stringWithFormat:@"%ld",i]].location != NSNotFound) {
CGContextSetRGBFillColor(ctx,34/255.f, 178/255.f, 246/255.f,1);
CGContextAddEllipseInRect(ctx,rect);
//CGPathAddEllipseInRect(pathM, NULL, rect);
CGContextFillPath(ctx);
}else{
CGPathAddEllipseInRect(pathM, NULL, rect);
}

}else{
CGPathAddEllipseInRect(pathM, NULL, rect);
}
}

//加入路径
CGContextAddPath(ctx, pathM);

//绘制路径
CGContextStrokePath(ctx);

//释放路径
CGPathRelease(pathM);
}

@end

到此，对于demo的改动已基本结束。不得不说，这位大神的demo很强大

以下是关于怎样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。并没实用系统提供的launchScreen

所以，登录跳转还是比較方便，在启动画面的controller里面推断假设设置了手势。就跳转到手势登录界面。手势登录效果图：



代码也非常easy，在storyboard中拉一个viewcontroller。选择好我们的手势登录类即可了：

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。

最后是其它跳转了，

如今的主要逻辑是。app缓存到后台之后5分钟，我就会跳转到手势锁屏，其它情况，临时没考虑。

所以我在AppDelegate.m中的applicationDidEnterBackground和applicationWillEnterForeground中做了简单的事情。代码例如以下：

- (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;

applicationDidEnterBackground中记录时间，applicationWillEnterForeground依据时间显示手势界面。当然。这里面也有推断是否设置手势。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。两个点之间我略微的从外面绕一下，就导致中间的点没连上，真是郁闷啊，因为时间比較冲忙，后面我肯定也要解决问题的，只是。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，推断这个坐标里面是否有button。有的情况，推断是否已经加入，没有就加进去。

因为是第一次做ios。并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个月的时间完毕公司的产品，前面也说过。我是做的android版。然后相应的ios版，也是我来做，时间非常的仓促。非常多的地方也有不懂之处，代码写的也比較乱，希望大家不要歧视。

。。。

嘛，就这样愉快的做ios吧。啦啦啦~~~~~~
