How to show UIView only when i received all data from server

问题

I am getting data from server in my application. Currently I making this using NSUrlConnection and getting data in connectionDidFinishLoading. Mean while i am showing an alertView to user. but that time my view is not updated with data.

I can only show while whole response is came form server and refreshing the view later.

Can i restrict view to shown up only when whole response is acquired or can i make the that dark effect of uialertview more dark which make containing view disable???

EDIT:

From all answers i would like to know that can i make gray effect of UIAlertView more dark or may i change it with other color ? or can someone explain me how its shown up ??

回答1:

1)In viewDidLoad method you can add another temporary view with dark gray background color.

2)Add activity indicator in this temporary view & start that indicator and set user interaction disable for self view.

3)In connectionDidFinishLoading stop the indicator & remove temporary view and enable user interaction of self view.

回答2:

You can add a overlay of darker color and an UIActivityIndicator, make the userInteraction disabled for that period for time
