FBSDKProfile category frequently fails - ios

Question

I wrote a category for FBSDKProfile provided by the Facebook SDK V4 for iOS. This category enables me to fetch the user profile image and access it using the [FBSDKProfile currentProfile] singleton instance.
This is my category header file:
#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <objc/runtime.h>
static char const * const kProfileImageKey = "profile_image";
#interface FBSDKProfile (ProfileImage)
+(void)fetchProfileImageWithBlock:(void (^)(BOOL succeeded))handler;
#property (nonatomic, strong) UIImage *profileImage;
#end
And here's the implementation file:
#import "FBSDKProfile+ProfileImage.h"
#implementation FBSDKProfile (ProfileImage)
+(void)fetchProfileImageWithBlock:(void (^)(BOOL succeeded))handler {
FBSDKProfile *currentProfile = [FBSDKProfile currentProfile];
NSString *userId = currentProfile.userID;
if (![userId isEqualToString:#""] && userId != Nil)
{
[self downloadFacebookProfileImageWithId:userId completionBlock:^(BOOL succeeded, UIImage *profileImage) {
currentProfile.profileImage = profileImage;
[[NSNotificationCenter defaultCenter] postNotificationName:FBSDKProfileDidFetchProfileImageNotification object:nil];
if (handler) { handler(succeeded); }
}];
} else
{
/* no user id */
if (handler) { handler(NO); }
}
}
+(void)downloadFacebookProfileImageWithId:(NSString *)profileId completionBlock:(void (^)(BOOL succeeded, UIImage *profileImage))completionBlock
{
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"https://graph.facebook.com/%#/picture?type=large", profileId]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[NSURLConnection sendAsynchronousRequest:request
queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
if (!error)
{
UIImage *image = [[UIImage alloc] initWithData:data];
completionBlock(YES, image);
} else{
completionBlock(NO, nil);
}
}];
}
#pragma mark - custom getter/setter methods
-(void)setProfileImage:(UIImage *)profileImage {
objc_setAssociatedObject(self, kProfileImageKey, profileImage, OBJC_ASSOCIATION_ASSIGN);
}
-(UIImage *)profileImage {
return objc_getAssociatedObject(self, kProfileImageKey);
}
#end
The problem
This solution works just the way it should most of the time, but it does, however, frequently fail. From what I can tell, I think it has to do with the storage of the image.
Upon the exception, if I do po [FBSDKProfile currentProfile].profileImage, it returns:
error: property 'profileImage' not found on object of type 'FBSDKProfile *'
error: 1 errors parsing expression
If I hover the pointer over a [FBSDKProfile currentProfile] instance, it doesn't display the profileImage property in the list of properties.
This is where it failed:

May be this could help you.
-(void)getFacebookProfileInfos:(NSString*)token{
FBSDKGraphRequest *requestMe = [[FBSDKGraphRequest alloc]initWithGraphPath:#"me" parameters:#{#"fields":#"id, name, picture.type(large),email"}];
FBSDKGraphRequestConnection *connection = [[FBSDKGraphRequestConnection alloc] init];
[connection addRequest:requestMe completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error)
{
if(result)
{
APP_DELEGATE.socialEmail=result[#"email"];
APP_DELEGATE.socialName= result[#"name"];
APP_DELEGATE.socialImage= result[#"picture"][#"data"][#"url"];
APP_DELEGATE.socialAcessToken=token;
HomeVC *obj = SB_IDENTIFIER(#"home");
SB_PUSH(obj);
}
else
{
NSLog(#"%#", [error localizedDescription]);
}
}];
[connection start];
}
