iOS通过Runtime实现友盟统计的实例代码

编辑: admin 分类: 苹果教程 发布时间: 2022-03-30 来源:互联网

在友盟官网可以看到相应的步骤,申请appkey,导入SDK,然后在AppDelegate里面写入相应的代码,下面就是关键的代码:

实现页面的统计需要在每个UIViewController中配对调用如下方法:

  - (void)viewWillAppear:(BOOL)animated
  {
    [super viewWillAppear:animated];
    [MobClick beginLogPageView:@"PageOne"];//("PageOne"为页面名称,可自定义)
  }
- (void)viewWillDisappear:(BOOL)animated 
  {
    [super viewWillDisappear:animated];
    [MobClick endLogPageView:@"PageOne"];
  }

几年之前做过这个,那时候才刚开始做iOS,就按照这个文档在每一个UIViewController里面写了这个方法,现在看来真是太low了。

这次又做这个友盟统计,就想起来用runtime解决这个问题。

在工程中创建一个UIViewController的Category,然后通过Runtime动态添加两个方法,分别替代viewWillAppear和viewWillDisappear方法。这样就不需要在每一个 UIViewController写这段代码了。

新建一个分类:

@implementation UIViewController (Statistics)


+ (void)load {

  //原本的viewWillApper方法
  Method viewWillAppear = class_getInstanceMethod(self, @selector(viewWillAppear:));

  //需要替换成能够输入日志的viewWillAppear
  Method logViewWillAppear = class_getInstanceMethod(self, @selector(logViewWillAppear:));


  //原本的viewWillDisappear方法
  Method viewWillDisappear = class_getInstanceMethod(self, @selector(viewWillDisappear:));
  //需要替换成能够输入日志的viewWillDisappear
  Method logviewWillDisappear = class_getInstanceMethod(self, @selector(logviewWillDisappear:));

  //两方法进行交换
  method_exchangeImplementations(viewWillAppear, logViewWillAppear);
  method_exchangeImplementations(viewWillDisappear, logviewWillDisappear);

}
-(void)logViewWillAppear:(BOOL)animated
{
  [self logViewWillAppear:animated];  
  NSString *selfClass = NSStringFromClass([self class]);
  [MobClick beginLogPageView:selfClass];
  //当然这里也可以使用self.title作为页面的名称,这样在友盟后台查看的时候更加方便些
  //[MobClick endLogPageView:self.title];  
}

-(void)logviewWillDisappear:(BOOL)animated
{
  [self logviewWillDisappear:animated];
  NSString *selfClass = NSStringFromClass([self class]);
  [MobClick endLogPageView:selfClass];
}


@end
