如何从我的应用程序发送文本到特定的WhatsApp用户？-Java 学习之路

我想从我的应用程序向特定的WhatsApp用户发送短信（“例如Hello World”） .

基于此whatsapp FAQ link，我可以使用自定义URL方案使用预定义文本向特定联系人号码启动whatsapp：

Question:

1) But where to get the contact ID, abid?:

2) How do I know if the contact number has whatsapp in the first place [for iOS we can't access it because of sandbox limitation right?] ?

3) How to insert the contact ID into the URL:

NSURL *whatsappURL = [NSURL URLWithString:@"whatsapp://send?text=Hello%2C%20World!"];

if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {
    [[UIApplication sharedApplication] openURL: whatsappURL];
}

您可以改为 UIactivityViewController ，以便显示支持您文字的应用：

NSString * text = @"Hello World!!";
NSArray * itemsArray = @[text];
NSArray * applicationActivities = nil;

UIActivityViewController * activityViewController = [[UIActivityViewController alloc] initWithActivityItems:itemsArray applicationActivities:applicationActivities];

activityViewController.excludedActivityTypes = @[
                                                 UIActivityTypePostToWeibo,
                                                 UIActivityTypeAssignToContact,
                                                 UIActivityTypeAirDrop,
                                                 UIActivityTypeAddToReadingList,
                                                 // Whatever you want prevent to appear...
                                                 ];

activityViewController.popoverPresentationController.sourceView = self.view;

[self presentViewController:activityViewController animated:YES completion:nil];

您还可以添加图像等 .
