How to share image via LINE

shareImageViaLine

- (void)shareImageViaLine:(UIImage *)image
{
    UIPasteboard *pasteboard =  [UIPasteboard generalPasteboard];
    //[pasteboard setData:UIImageJPEGRepresentation(image, 1.0) forPasteboardType:@"public.jpeg"];
    //→JPEGではできない模様　PNGならOK。
    [pasteboard setData:UIImagePNGRepresentation(image) forPasteboardType:@"public.png"];
    //PNGで！！！
    
    NSString *urlString = [NSString stringWithFormat:@"line://msg/image/%@",pasteboard.name];
    NSURL *url = [NSURL URLWithString:urlString];    
    [[UIApplication sharedApplication] openURL:url];
}

//LINEがインスコされてないとき用に、こうするとよさそう。(@t_okada さんより)
NSURL *url = [NSURL URLWithString:@"line://msg/image/"];
if (![[UIApplication sharedApplication] canOpenURL:url]){
lineButton.hidden = YES;
}
