#pragmamark返回当前UIView的UIController-(UIViewController*)funResponderVC{UIView*net=[supersuperview];//返回上一级的视图。直到找到UIViewController视图为止UIResponder*nextResponder=[nextnextResponder];if([nextResponderisKindOfClass:[UIViewControllerclass]]){return(UIViewController*)nextResponder;}else{returnnil;}}

UIViewController *vc = [[UIViewController alloc] init];

[[self funResponderVC] presentViewController:vc animated:YES completion:nil];

这样就实现了UIVIew的跳转，其实可以写在UIViewController，不必这么麻烦，可是考虑到代码的封装性以及代码后期的修改，所以遇到在UIVIew的跳转是必不可少的。
