iOS通过Runtime实现友盟统计的实例代码
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:
