ios - APP放置3天到一周，再次启动会很慢。

Question

APP放置3天到一周，再次启动会很慢。点击APP图标，大概会需要5秒以上才会进入启动页面。再次运行则秒进。请问这可能是什么方面的问题呢？ 程序中有引入百度地图。

Answer 1

It is recommended to check the following methods to see if there is any code that occupies the main thread for a long time

- (void)applicationDidFinishLaunching:(UIApplication *)application;
- (BOOL)application:(UIApplication *)application willFinishLaunchingWithOptions:(nullable NSDictionary *)launchOptions NS_AVAILABLE_IOS(6_0);
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(nullable NSDictionary *)launchOptions NS_AVAILABLE_IOS(3_0);

- (void)applicationDidBecomeActive:(UIApplication *)application;
- (void)applicationWillResignActive:(UIApplication *)application;
