Ios simulator app closes immediately. After you kill apps this way it takes slightly longer to open them than it does when they re suspended in the background. Been studying beginning iphone 3 development exploring the iphone sdk by dave mark and jeff lamarche. Hello everyone my idevice is.
All i see is a black background for few seconds. Iphone 5s ios version. I m up to chapter 4 and stuck now.
Can someone please tell me why. Now try to restart the app. Now long hold mouse over app and the close button will appear.
