I am making an IOS app where i am calling an API in viewDidLoad method of view controller. Now i want to reload the same view controller with the data that comes from server. How many ways are there to do this task and what would be the best way?? Please help me.
viewDidLoad method is called first time when
UIViewController is first loaded and when it pop and then you reenter in it at that time
viewDidLoad is called. So if you want to load the API only once then
viewDidLoad is the best place to call an API.
viewWillAppear called every time when you enter in that
UIViewController and it is the place load the API when you want to get refreshed data (updated data).
viewDidAppear also called like
viewWillAppear but bit late called than
viewWillAppear so if you want to call the API every time than the best place is
viewDidAppear method called late from
viewWillAppear method and you are just requesting the API so the response of API may be late and If your UI change based on API response then it will stuck the application UI so there is a best place to call API either
