【问题描述】：

如果向 WhatsApp 发送文本：

NSString *msg = @"Some Text";
NSString *urlWhats = [NSString stringWithFormat:@"whatsapp://send?text=%@",msg];
NSURL *whatsappURL = [NSURL URLWithString:[urlWhats stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {
  [[UIApplication sharedApplication] openURL: whatsappURL];
} else {
  UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"WhatsApp not installed." message:@"Your device has no WhatsApp installed." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
  [alert show];
}

如果将图像发送到 WhatsApp：

if ([[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:@"whatsapp://app"]]){

   UIImage* iconImage = [self captureScreen];// this will return a image
   NSString* savePath  = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/whatsAppTmp.wai"];

   [UIImageJPEGRepresentation(iconImage, 1.0) writeToFile:savePath atomically:YES];

   _documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
   _documentInteractionController.UTI = @"net.whatsapp.image";
   _documentInteractionController.delegate = self;

   [_documentInteractionController 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];
}

Whatsapp 打开时没有任何文本用于文本共享，并且图像也没有被共享。请帮我。

【解决方案1】：

您是否将“LSApplicationQueriesSchemes”添加到您的 plist 中？

转到您的项目/Supporting Files/YourProjectName-Info.plist in XCode 项目资源管理器。
添加新的键值对。钥匙： LSApplicationQueriesSchemes 类型：数组添加一个新的字符串项 “whatsapp”

请试试这个，如果它仍然不起作用，请告诉我。

【解决方案2】：

注意：- 您只能共享文本或图像，两者在 WhatsApp 中一起共享在 WhatsApp 端不起作用

 /*
    //Share text
    NSString *textToShare = @"Enter your text to be shared";
    NSArray *objectsToShare = @[textToShare];
    
    UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
    [self presentViewController:activityVC animated:YES completion:nil];
     */
    
    //Share Image
    UIImage * image = [UIImage imageNamed:@"images"];
    NSArray *objectsToShare = @[image];
    
    UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
    [self presentViewController:activityVC animated:YES completion:nil];
