标题: ios - Whatsapp 共享文本和图像在 ios 中不起作用

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 打开时没有任何用于文本共享的文本，并且图像也没有被共享。请帮我。

Best Answer-推荐答案

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

1. 转到您的项目/Supporting Files/YourProjectName-Info.plist 中 XCode 项目资源管理器。
2. 添加新的键值对。 key : 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。
