icon grey custom UIActivityViewController - ios

Question

I create a custom UIActivityViewController but when I load the icons that I do makes me see gray and you are pretty much loaded correctly, someone did it happen? how you have remedied?
ActivityViewCustomActivity *ca = [[ActivityViewCustomActivity alloc]init];
ca.service = #"avanti";
ca.image = image;
ca.act = #"com.avanti.app";
ActivityViewCustomActivity *fa = [[ActivityViewCustomActivity alloc]init];
fa.service = #"facebook";
fa.image = image;//[UIImage imageNamed:#"icon-facebook.jpg"];
fa.act = #"com.facebook.app";
ActivityViewCustomActivity *tw = [[ActivityViewCustomActivity alloc]init];
tw.service = #"twitter";
tw.image = image;
tw.act = #"com.twitter.app";
UIActivityViewController *activityVC =
[[UIActivityViewController alloc] initWithActivityItems:items
applicationActivities:#[ca,fa,tw]];
activityVC.excludedActivityTypes = #[UIActivityTypePostToTwitter,UIActivityTypePostToFacebook,UIActivityTypeMail,UIActivityTypePostToWeibo, UIActivityTypeAssignToContact, UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeSaveToCameraRoll];
activityVC.completionHandler = ^(NSString *activityType, BOOL completed)
{
if ([activityType isEqualToString:#"com.avanti.app"]) {
NSLog(#" activityType: %#", activityType);
NSLog(#" completed: %i", completed);
NSString *name = [q objectAtIndex:indexPath.row];
UIStoryboard *storyboar = [UIStoryboard storyboardWithName:#"Main_iPhone" bundle:nil];
ListViewController *list = [storyboar instantiateViewControllerWithIdentifier:#"ListViewController"];
list.ide = ide;
list.canale = name;
[self.navigationController pushViewController:list animated:YES];
}
else if ([activityType isEqualToString:#"com.facebook.app"]){
NSLog(#" activityType: %#", activityType);
NSLog(#" completed: %i", completed);
UIActionSheet *action = [[UIActionSheet alloc]initWithTitle:#"Facebook" delegate:self cancelButtonTitle:#"Annulla" destructiveButtonTitle:#"Vuoi pubblicarlo ?" otherButtonTitles:#"ok", nil];
action.actionSheetStyle = UIActionSheetStyleDefault;
[self actionSheet:action clickedButtonAtIndex:2];
[action showInView:[self.view window]];
}
else if ([activityType isEqualToString:#"com.twitter.app"]){
NSLog(#" activityType: %#", activityType);
NSLog(#" completed: %i", completed);
[self shareTwitter];
}
};
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
NSLog(#"ipad");
}
else
{
[self presentViewController:activityVC animated:YES completion:nil];
}
}
e l'activity è così
- (NSString *)activityType
{
return act;
}
- (NSString *)activityTitle
{
return service;
}
- (UIImage *)activityImage
{
// CGRect rect = CGRectMake(0.0f, 0.0f, 85.0f, 85.0f);
// UIGraphicsBeginImageContext(rect.size);
//
// rect = CGRectInset(rect, 15.0f, 15.0f);
// UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:rect cornerRadius:10.0f];
// [path stroke];
//
// rect = CGRectInset(rect, 0.0f, 10.0f);
// [service drawInRect:rect withFont:[UIFont fontWithName:#"Futura" size:15.0f] lineBreakMode:NSLineBreakByWordWrapping alignment:NSTextAlignmentCenter];
//
// UIImage *imag = UIGraphicsGetImageFromCurrentImageContext();
//
// UIGraphicsEndImageContext();
// //UIImage *ima = [UIImage imageNamed:#"facebook.jpg"];
// return imag;
UIImage *ima = [UIImage imageNamed:#"Icon_Facebook.png"];
return ima;
// if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
// {
// return [UIImage imageNamed:#"Facebook_43x43"];
// }
// else
// {
// return image;
// }
}
- (BOOL)canPerformWithActivityItems:(NSArray *)activityItems
{
NSLog(#"%s", __FUNCTION__);
for (id obj in activityItems) {
if ([obj isKindOfClass:[NSString class]]) {
return YES;
}
}
return NO;
}
- (void)prepareWithActivityItems:(NSArray *)activityItems
{
NSLog(#"%s",__FUNCTION__);
}
- (UIViewController *)activityViewController
{
NSLog(#"%s",__FUNCTION__);
return nil;
}
- (void)performActivity
{
// This is where you can do anything you want, and is the whole reason for creating a custom
// UIActivity
[self activityDidFinish:YES];
}
+ (UIActivityCategory)activityCategory
{
return UIActivityCategoryShare;
}
and the screenshot is here http://i57.tinypic.com/332vtjo.png
and .h is
#import <UIKit/UIKit.h>
#interface ActivityViewCustomActivity : UIActivity
#property (nonatomic, strong) NSString *service;
#property (nonatomic, strong) UIImage *image;
#property (nonatomic, strong) NSString *act;
- (NSString *)activityType;
- (NSString *)activityTitle;
- (UIImage *)activityImage;
- (BOOL)canPerformWithActivityItems:(NSArray *)activityItems;
- (void)prepareWithActivityItems:(NSArray *)activityItems;
- (UIViewController *)activityViewController;
- (void)performActivity;
+ (UIActivityCategory)activityCategory;
#end

Try to add _ to your activityImage function
Something like
- (UIImage *)_activityImage
{
return [UIImage imageNamed:#"Icon_Facebook.png"];
}
