@QuocNguyen I am not sharing only in email but share also in another app. — Chirag Kothiya, Jun 06 '18 at 06:01
You are sending nil data here, means image not getting from self.imageView.image. You check this if(self.imageView.image == nil) { } else { UIImage *image = self.imageView.image; //and write remaking code here } — iOS, Jun 06 '18 at 06:07
@ChiragKothiya you can check when `activityType` is Mail for avoid the crash — Quoc Nguyen, Jun 06 '18 at 06:08

Your attach that you are sharing is nil, is the reason you are getting a crash at run time.

before attaching an attachment you need to check wether attachment file is available or not.

for eg.

if (self.imageView.image == nil) {
    NSLog("image not available.")
    return
}
