ios - UIImagePickerController crashes when using PhotoLibrary as source -

-

i'm using xcode 5.1 , tested code both on ios7.1 , 7.0.2. app crashes uiimagepickercontroller in 2 scenarios on device:

1) when allowsediting set yes, after crop picture , press "choose", goes own view, app crashes

2) inside uiimagepickercontroller, when go photo list album list , @ bottom of photo list, crashes (no matter allowsediting yes or not). note not crash if scrolled photo list up.

here code:

- (ibaction)photopickpressed:(id)sender {      if ([self isphotolibraryavailable]) {          self.imagepicker = [[uiimagepickercontroller alloc] init];         self.imagepicker.delegate = self;         self.imagepicker.sourcetype = uiimagepickercontrollersourcetypephotolibrary;         self.imagepicker.allowsediting = yes;         nsstring *requiredmediatype = (__bridge nsstring*)kuttypeimage;         self.imagepicker.mediatypes = [[nsarray alloc] initwithobjects:requiredmediatype, nil];         [self presentviewcontroller:self.imagepicker animated:yes completion:nil];     } }  #pragma mark - image picker delegates - (void)imagepickercontroller:(uiimagepickercontroller *)picker didfinishpickingmediawithinfo:(nsdictionary *)info{     [picker dismissviewcontrolleranimated:yes completion:^(){         nslog(@"finished image picking");     }); }  - (void)imagepickercontrollerdidcancel:(uiimagepickercontroller *)picker{     [picker dismissviewcontrolleranimated:yes completion:nil]; }

the crash message is

* terminating app due uncaught exception 'nsinvalidargumentexception', reason: '* -[nsproxy doesnotrecognizeselector:scrollviewdidscroll:] called!'

note: not crash if use camera if set allowsediting yes. only crashes on real devices, not on simulator.

just clarify (maybe unrelated), declared imagepicker as

uiimagepickercontroller *imagepicker = [[uiimagepickercontroller alloc] init];

, , crashed. googled lot, , post says controller might recycled, , suggested declare in class definition. declared in class declartion:

@property (strong, nonatomic) uiimagepickercontroller *imagepicker;

thanks in advance.

update: tried put invoke of imagepickercontroller root view of app, , still crashes same message. shouldn't have scrollable view loaded yet.

after hours of investigation , tryout, confirmed caused third-party framework integrated app: empty app crashes uiimagepickercontroller if link framework there.

thank help!
