填坑
支付宝填坑是每个接入支付宝必经之路，下面是我接入支付宝遇到的问题汇总，希望大家在接入的路上少一点弯路
问题1. Util/base64.h:63:21: Cannot find interface declaration for ‘NSObject’, superclass of ‘Base64’
解决办法：这是base64.h中没有加入#import 系统库文件导致，这个错误报错方法直接想喷它一脸。报错方式太恶心。
问题2.截图告知你什么问题
解决办法：这个问题可以同上的，心情好，截图再次说明下，在 openssl_wrapper.h中#import 库即可
问题3.Util/openssl_wrapper.m:11:9: ‘rsa.h’ file not found
解决办法：（1），万年老坑，只要你接入支付宝百分百要遇到的问题，所以习以为常吧（2），在Build setting中搜索search，找到Header Search Paths，添加$(PROJECT_DIR)/openssl和$(PROJECT_DIR) 如下图：（3），重要 问题说三遍，这是网络找到的到答案后继续有同样的坑，自己的解决方案,Header Search Paths $(PROJECT_DIR)/ali中输入这个Framework Search Paths 和 Library Search Paths 继续是$(inherited) 和 $(PROJECT_DIR)/ali‘rsa.h’ file not found 的解决方案（4），由于后期多项目的接入，让我知道一个算是万能方法吧，就是始终保持Header Search Paths 和 Library Search Paths 都能找到你导入的openssl的正确路径即可，已尝试多遍，是能解决以上问题（求黑）
问题4.这类错很多，大概有这些：这些可能是库文件没有导入，导致的

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
解决办法：这种问题通过在General->Link Framework and Libraiies中添加以下framework解决：- libz.tbd- libc++.tbd- Security.framework- CoreMotion.Framework- CFNetwork.framework- CoreTelephony.framework- SystemConfiguration.framework
截图如下，由于公司同时接入支付宝和微信支付，所以导入的库就多了点咯：
问题5.Redefinition of 'RSA' as different kind of symbol 多为sdk集成时产生的坑，因为我们公司在集成支付宝之前，有用过RSA加密，导致重名问题
解决办法：
（1），这个问题不是每个公司都可能遇到的，但遇到也心烦
（2），由于支付宝中的openssl中的rsa.h文件与RSA加密有重名冲突。改掉公司自己之前导入RSA的命名，如果你牛逼也可以去改rsa.h中的
问题6；系统库导入问题
+++++++++++++
symbol(s) not found for architecture arm64
解决办法
就是导入系统库了
问题7：
拉起支付宝报错：
交易订单处理失败,请稍后再试(ALI64)
解决办法：
重新生成私钥和公钥，执行步骤如下个问题
问题8：
支付宝要重新生成私钥和公钥，并上传修改公钥 -- 为你补充
解决办法：
RSA密钥生成命令步骤如下：
(1)先在终端键入 openssl
生成RSA私钥
(2)openssl>genrsa -out rsa_private_key.pem 1024
生成RSA公钥
(3)openssl>rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem
将RSA私钥转换成PKCS8格式
(4)openssl>pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt
注意：“>”符号后面的才是需要输入的命令。

这里写图片描述
把公钥上传到支付宝，然后把pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt 这条命令产生的私钥用在下面设置中就好
然后设置
/* *商户的唯一的parnter和seller。 *签约后，支付宝会为每个商户分配一个唯一的 parnter 和 seller。 */ /*============================================================================*/ /*=======================需要填写商户app申请的===================================*/ /*============================================================================*/
NSString *partner = PartnerID;//合作伙伴身份（PID）:
NSString *seller = SellerID;//商户支付宝账户
//获取私钥并将商户信息签名,外部商户可以根据情况存放私钥和签名,只需要遵循RSA签名规范,并将签名字符串base64编码和UrlEncode
NSString *privateKey = PartnerPrivKey;// 刚第三端命令生成的去头去尾
