一、微信支付，首先利用CocoaPods,导入微信支付SDK
pod 'WechatOpenSDK'
注意：导入重新运行项目会报错：ld: in /Users/renhuaqian/Documents/mutableTarges/mb-ios/MosoBooksPhone/ClassLibrary/UMShareSDK/WeChat/libWeChatSDK.a(WechatAuthSDK.o), building for iOS Simulator, but linking in object file built for iOS, file '/Users/renhuaqian/Documents/mutableTarges/mb-ios/MosoBooksPhone/ClassLibrary/UMShareSDK/WeChat/libWeChatSDK.a' for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
解决：
1.podFile加下面代码
post_install do |installer| installer.pods_project.build_configurations.each do |config| config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64" endend
2.buildSetting中,加如下信息,然后clean项目, 再pod install下; 重新运行项目就能在模拟器运行了
二、在你需要使 用微信终端 API 的文件中 import WXApi.h 头文件，并增加 WXApiDelegate 协议。
#import
#import "WXApi.h"//导入微信API
@interface AppDelegate : UIResponder <UIApplicationDelegate,WXApiDelegate>
@property (strong, nonatomic) UIWindow * window;
@end
