写这篇文章的主要目的是做一个学习的备忘，避免同样的坑再爬一遍😄，下面开始正文。
文章的顺序，就是开发的流程
1、将Alipay SDK包，添加到项目中
Alipay SDK
2、编译项目，会出现以下问题：
1）"Unknown type name ‘NSString‘ "或"Unknown type name ‘NSData‘ "
，但是本人并没有遇到，参考网友的时候有这样的问题，一并附上，主要看解释原因
报错信息
这是因为缺少Foundation类库和UIKit类库，支付宝Demo中之所以没有出现此错误，是因为在.pch文件中导入过这些类库
解决办法：只需要在出现错误的文件中导入这些类库即可
需要导入的库
2）‘openssl/asn1.h‘ file not found，这个坑填了几个小时😄
报错信息
这是openssl文件夹头文件链接问题，如果openssl文件夹随意拉进项目中，即使添加头文件链接，也可能解决不了此问题，这也是一开始就将所需要的文件放到一个新建文件夹中再添加到项目中的原因。（试了各种方法添加，最终是先将Alipay拖放到文件中，再将Alipay拖到项目工程中，这样添加的）
解决办法：
Targets->Build Settings->Header Search Path中添加AliPaySDK文件夹的路径

截图
具体怎么写（一个参数设置的时候）
多个参数设置的时候
这个参数需要设置多个值的时候，通过双引号括起来
3）linker command failed with exit code 1 (use -v to see invocation)
这边的解决办法：”Build Settings”->”Enable Bitcode”设置为NO
（附带的将Other Linker Flags下的属性全删除了，可能不删除也是可以跑的，没有试）
4.编译项目，会出现以下问题：
报错信息
解决方法:在xcode中，点击项目名，选择"target"->"Link Binary With Libraries"添加依赖库。
需要添加的库
编辑程序，已经可以成功编译了，接下来就是集成代码了，这边主要做的是直接在前端集成代码
5、添加非https请求

(App Transport Security Settings 和Allow Arbitrary Loads)

PrefixHeader.pch-配置一下pch文件
#ifndef PrefixHeader_pch
#define PrefixHeader_pch
#define ALIPAY_SUCCEEDED @"alipaySucceeded"
#endif /* PrefixHeader_pch */
7、配置LSApplicationQueriesSchemes
LSApplicationQueriesSchemes配置
LSApplicationQueriesSchemes不配置的话，是在项目内调用支付宝进行支付；
配置了LSApplicationQueriesSchemes参数，它会自动判断当前手机有没有安装支付宝，安装了就跳支付宝应用，没有安装直接应用内跳支付宝支付
（只要设置alipay这一个参数就可以了）
8、配置URL Schemes
URL Schemes plist中配置
这边涂鸦掉的是代码中 [[AlipaySDK defaultService] payOrder:orderString fromScheme:appScheme callback:^(NSDictionary *resultDic) {
里面的appScheme参数设置成一样的，这样支付宝回调的时候就知道调用手机中那个标识的应用
一般不在plist文件中设置这个参数，而是在图形界面中，这样比较的方便
URL Schemes图形配置
URL Schemes配置，主要可以让支付宝可以正确的回调当前应用，并传人相关的支付信息（成功、失败、取消）
9、遇到的问题-备注一下，便于理解
1）、在AppDelegate.m中加入这两个方法（对旧版本的支持）：
//重要更新，一下两个方法IOS9.0以后被废弃了，所以如果你是Xcode7.2的话，可能会出现不能进入微信的onResp回调方法，原因是下边两个方法没有被调用，所以这里更新一下，改用另外一个方法（并不建议删除这两个方法，新方法是9.0以后的方法，可能系统低版本的用户不支持。所以我三种方法都留下了，如果有人发现不能都留下的话，请简信告诉我一下，再次谢过了）
-(BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url；
-(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation；
//改用方法为
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary*)options；
2）、支付宝回调的时候分两种情况，客户端装了支付宝和没有装支付宝两种情况
情况一：客户端装了支付宝
通过在delegate中handleOpenURL或者openURL接受支付回调，支付成功时通过通知去支付界面进行销单处理
情况二、客户端没有安装支付宝
会在支付宝调用界面，执行block，方法如下图
