ios - 无需菜单 ios 即可自动分享到 whatsapp

Question

我有一个声音想在 Whatsapp 上分享，使用 UIDocumentInteractionController 它工作得很好，但我不想促使用户选择 Whatsapp，我希望它被立即选中。这可能吗？

对于我想要的文本共享，它会立即使用深层链接打开 Whatsapp

whatsapp://send?text=test

我不希望在共享声音时显示此菜单:

Answer 1

对于文本:

NSString * msg = @"Your 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];

}

对于图像:

.h 文件:

<UIDocumentInteractionControllerDelegate>

@property (retain) UIDocumentInteractionController * documentInteractionController;

.m 文件:

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

        UIImage     * iconImage = [UIImage imageNamed:@"YOUR 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];
 }
