Question

Today when testing app on iOS 5, I've found a problem, it crashes on starting.

dyld: Symbol not found: _OBJC_CLASS_$_UIActivityViewController
  Referenced from: /var/mobile/Applications/6F884421-A676-434B-89E0-598F4F8F277F/HGroupware.app/HGroupware
  Expected in: /System/Library/Frameworks/UIKit.framework/UIKit
 in /var/mobile/Applications/6F884421-A676-434B-89E0-598F4F8F277F/HGroupware.app/HGroupware

So what should I do? Change deployment target to iOS >= 6.0 or any solution? Please help me.

Was it helpful?

Solution

Yes only solution is IOS >=6. Because UIActivityViewController is only available from IOS6. See this apple's doc

OTHER TIPS

UIActivityViewController is "Available in iOS 6.0 and later.", so ideally, yes, change deployment target. Or change it on something else in code if [UIActivityViewController class] returns nil.
