sharedApplication takes long to display - ios

Question

So I added some code to this to work on both ios 8 and 9(5s and ipad). Before the change the 5s would load the share dialog fairly quick while the ipad would crash the device. After adding the fix they both don't crash, but now the ipad displays the share dialog fairly quick while the 5s takes roughly ~1-2 mins to display it. Not sure why that might be, maybe I did something wrong with my change?
#import <Foundation/Foundation.h>
extern "C" {
void _shareText(const char *text, const char *imgUrl)
{
NSString * message = [NSString stringWithUTF8String:text];
NSString * urlAddress = [NSString stringWithUTF8String:imgUrl];
NSURL *url = [NSURL URLWithString:urlAddress];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *img = [[UIImage alloc] initWithData:data];
NSMutableArray *sharingItems = [NSMutableArray new];
if (text) {
[sharingItems addObject:message];
}
if (img) {
[sharingItems addObject:img];
}
UIViewController *qtController = [[UIApplication sharedApplication].keyWindow rootViewController];
UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:sharingItems applicationActivities:nil];
if ([activityController respondsToSelector:#selector(popoverPresentationController)] ){
[qtController presentViewController:activityController animated:YES completion:nil];
activityController.popoverPresentationController.sourceView = qtController.view;
}else{
[qtController presentViewController:activityController animated:YES completion:nil];
}
}
}
Update:
Unity Called function:
[DllImport("__Internal")]
private static extern void _shareText(string message, string imgUrl);
public static void InviteRequest(string message, string imgUrl)
{
#if UNITY_IOS
if (Application.platform != RuntimePlatform.OSXEditor)
{
_shareText(message, imgUrl);
}
#endif
}
