我有UIActivityViewController3 种不同类型的活动项目。
NSString,UISimpleTextPrintFormatter和UIImage.
当我在推特、脸书或作为邮件发送时，系统总是添加字符串和图像，但是当我打印系统时，UISimpleTextPrintFormatter除非我从NSArray. 我怎样才能告诉UIActivityViewController使用UIImage打印代替？
NSString *textToShare
= [NSString stringWithFormat:@"%@ %@ %i",
_car.make,_car.model, _car.constructionYear];
UISimpleTextPrintFormatter *textDataToShare
= [[UISimpleTextPrintFormatter alloc] initWithText:textToShare];
UIImage* imageToShare = [UIImage imageNamed:_car.picture];
NSArray* items = @[textToShare,imageToShare,textDataToShare];
UIActivityViewController *activityViewController
= [[UIActivityViewController alloc]
initWithActivityItems:items applicationActivities:nil];
