Adding delay between execution of two following lines

Question

I need to add delay between the execution of two lines in a(same) function. Is there is any favorable options to do this?

Note: I don\'t need two di

Answer 1

You can use the NSThread method:

[NSThread sleepForTimeInterval: delay];

However, if you do this on the main thread you'll block the app, so only do this on a background thread.

or in Swift

NSThread.sleepForTimeInterval(delay)

in Swift 3

Thread.sleep(forTimeInterval: delay)
