I have used Autolayout in storyboard and it was working fine in ios7 before a week. but I have altered some constraints before 2 days after that app is not running in iOS7. I am getting following warning in storyboard.

"Automatic preferred max layout width is not available on ios versions prior to 8.0"

in xcode console window I am getting following error,

"Terminating app due to uncaught exception 'NSInvalidArgumentException',
 reason: 'Unable to create description in descriptionForLayoutAttribute_layoutItem_coefficient. 
Something is nil'"

Could anyone please help me to find the solution.

Thanks in Advance

  • @Sakthi are you setting constraints with "constraint with margin" as tick you cannot run in ios7 – TamilKing Jun 01 '15 at 06:54
