iOS微信支付SDK开发经验

首先遇到的问题就是微信SDK版本，

在微信开放平台下了官方SDK，在编译的时候各种报错，

"_OBJC_CLASS_$_WXApi", referenced from:​

symbol(s) not found for architecture x86_64​

在Google上找了一下午，真是浪费时间。后来发现下载的官方SDK解压后有两个文件夹：​WeChatSDK_1.5 和 WeChatSDK_1.5_OnlyIphone。

我开发的是iphone版，所以想都没想就直接用了WeChatSDK_1.5_OnlyIphone​，结果就是一直报错。

折腾了半天，改用WeChatSDK_1.5，不报上面的错误了，改成以下错误了

Undefined symbols for architecture x86_64: "operator delete[](void*)", referenced from: +[WeChatApiUtil EncodeBase64:] in libWeChatSDK.a(WeChatApiUtil.o) +[WeChatApiUtil NsDataEncodeBase64:] in libWeChatSDK.a(WeChatApiUtil.o) +[WeChatApiUtil DecodeWithBase64:]

在网上查了半天，Linked Frameworks and Libraries里除了导入微信官方要求的东西外，还要添加​libc++.dylib。

于是，编译通过了......​
