尝试像从普通iPhone上一样从模拟器中删除它，然后从XCode运行.如果这不起作用，请退出模拟器，然后转到$ {HOME}/Library/Application Support/iPhone Simulator/$ {OS_VERSION}/Applications.每个应用程序都有一个以应用程序ID命名的文件夹.查找适合您的应用程序的文件夹并将其删除.然后从XCode重新运行.

Try just deleting it from the simulator as you would on a normal iPhone, then running from XCode. If that doesn't work, quit the simluator and go to ${HOME}/Library/Application Support/iPhone Simulator/${OS_VERSION}/Applications. There will be folders for each application named after the application's id. Find the folder for your application and delete it. Then run again from XCode.
