前言
之前调通了支付宝demo，开始往自己工程拖东西吧，我为什么觉得我可能把所以的问题都遇到了呢+_+，赶紧把问题记录下来 不然下次弄还费劲，加一句，要不真的用ping++吧 ?
正文：
1.先把demo中的工程直接拷过来
2.添加相应的依赖库.选择"target"->"Link Binary With Libraries"
3.编译 开始报错了吧 哇咔咔
unknown type name 'NSString'
解决:在相应文件中,导入
#import
#import
4."openssl/asn1.h"file not fount
还有这个
这个找不到
解决:出现类似找不到文件的情况,Targets->Build Settings->Header Search Path添加路径.
直接将项目中的相应文件拖入即可.也可以$(SRCROOT)/文件路径.
至此,基本的工作完成.下面开始集成代码
$(PROJECT_DIR)/文件夹名 （这里说一下，直接点击openssl，然后showinfinder，然后command + i 查看路径,把得到路径的工程名字以后的部分加在文件夹名这OK了）

Re:no matching function for call to 'PEM_read_bio_RSAPrivateKey'
改为
rsa_private = PEM_read_bio_RSAPrivateKey(bio_private, NULL, NULL, NULL);
6.
No matching function for call to"EVP_EncodeBlock"
把
int outputLength = EVP_EncodeBlock(outputBuffer, [signature bytes], signatureLength);
改为
int outputLength = EVP_EncodeBlock(outputBuffer, (unsigned char *)[signature bytes], signatureLeng
7.
这种问题 就把demo里的这两个工程

这种错误 就是没有添加Security.framework的报错
好累有木有，希望对大家有帮助 ?
