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。

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:

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
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;
@property (nonatomic,assign) BOOL needLine;
再把这个类中的方法加入一个參数
@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]; }
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。

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:

}; } -(void)toLogin{ [self performSegueWithIdentifier:@"toLogin" sender:self]; } -(void)clearDB{ [prop writeValueByFieldName:@"gestureFlag" withValue:@"0"]; [prop writeValueByFieldName:@"gesturePwd" withValue:nil]; [prop writeValueByFieldName:@"gestureTryCnt" withValue:@"5"]; [prop writeValueByFieldName:@"devicetoken" withValue:nil]; [prop writeValueByFieldName:@"pub.gestureShowed" withValue:@"0"]; } -(IBAction)otherLogin:(id)sender{ [prop writeValueByFieldName:@"devicetoken" withValue:nil]; [prop writeValueByFieldName:@"pub.gestureShowed" withValue:@"0"]; [CommonData shareInstance].needBack = NO; [self performSegueWithIdentifier:@"toLogin" sender:self]; } @end
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~~~~~~
