使用说明: main.m文件最顶部参数设定，修改输出路径

//引入的头文件 NSString *PublicHeader = @"APublicHeader.h"; //外部(delegate)调用的类 NSString *publicCallClassName = @"ASpamCode_Public"; //垃圾代码输出路径 NSString *outDirectory = @"/Users/zengchunjun/workspace/SDK_Tools/SpamCode2";

在Xcode工程 delegate中添加如下方法

• (void)addSpamCodeMethod { CFAbsoluteTime startTime =CFAbsoluteTimeGetCurrent();

  int random = 1234567; if (random % 2 == 0) { //没有必要调用 [ASpamCode_Public main_X10_Call:@"ios" bmg_X12_:@"android"]; }

  CFAbsoluteTime linkTime = (CFAbsoluteTimeGetCurrent() - startTime);

  NSLog(@"Linked in %f ms", linkTime *1000.0); }

并在didFinishLaunchingWithOptions方法中调用

• (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

  [self addSpamCodeMethod];//添加额外的code

  return YES; }
