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):

技术分享


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:


技术分享


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:


技术分享

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:


技术分享


"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。

            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;
                [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~~~~~~
