我需要share image和text直接WhatsApp。我尝试使用actionsheet和UIDocumentIntractionController。
我尝试使用此代码：
if ([[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:@"whatsapp://app"]]){
[AdDetailsViewController processImageDataWithURLString:self.strThumbImage andBlock:^(NSData *imageData) {
self.watsappShareimg = [[UIImage alloc]initWithData:imageData];
}];
UIImage * iconImage = self.watsappShareimg; //[UIImage imageNamed:@"flag.png"];
NSString * savePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/whatsAppTmp.wai"];
[UIImageJPEGRepresentation(iconImage, 1.0) writeToFile:savePath atomically:YES];
self.documentationInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
self.documentationInteractionController.UTI = @"net.whatsapp.image";
self.documentationInteractionController.delegate = self;
[self.documentationInteractionController presentOpenInMenuFromRect:CGRectMake(0, 0, 0, 0) inView:self.view animated: YES];
} else {
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"WhatsApp not installed." message:@"Your device has no WhatsApp installed." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
}
提前感谢你

分享UIActivityViewController，image或text。这是Apple默认分享方法
URL您可以尝试上面的代码https://www.whatsapp.com/faq/en/iphone/23559013
在此NSString *shareText = @"This is Sharable text";
UIImage * image = [UIImage imageNamed:@"Test.png"];
NSArray *array_Object = @[shareText, image];
UIActivityViewController *obj_activity = [[UIActivityViewController alloc] initWithActivityItems:array_Object applicationActivities:nil];
[self presentViewController:controller animated:YES completion:nil]
他们Link只共享独立文字。对于Mentioned，Image，audio使用Video。
