W iOS 8 mam problem z przechwytywaniem zdjęć z aparatu, do tej pory używam tego kodu
UIImagePickerController *controller=[[UIImagePickerController alloc] init];
controller.videoQuality=UIImagePickerControllerQualityTypeMedium;
controller.delegate=(id)self;
controller.sourceType=UIImagePickerControllerSourceTypeCamera;
[self presentViewController:controller animated:YES completion:nil];
Ale w iOS 8 otrzymuję to:
Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates.
Próbowałem z rozwiązaniem dostarczonym przez ten post z
@property (strong,nonatomic)UIImagePickerController *controller;
_controller=[[UIImagePickerController alloc] init];
_controller.videoQuality=UIImagePickerControllerQualityTypeMedium;
_controller.delegate=(id)self;
_controller.sourceType=UIImagePickerControllerSourceTypeCamera;
_[self presentViewController:controller animated:YES completion:nil];
i to
...
controller.modalPresentationStyle=UIModalPresentationFullScreen;
or
controller.modalPresentationStyle=UIModalPresentationCurrentContext;
...
i to
double delayInSeconds = 0.1;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
[self presentViewController:controller animated:YES completion:nil];
});
i to
[self presentViewController:controller animated:YES completion:NULL];
i to
[self presentViewController:controller animated:YES completion:^{
}];
dowolny pomysł?
dispatch_async(dispatch_get_main_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
zmieniłem nadispatch_async(dispatch_get_main_queue(), ^{
