WhatsApp图像共享iOS [关闭]

Question

我正在开发一个 iOS 应用程序，我必须从我的应用程序在 WhatsApp 上共享图像。我找到了这段代码，但它只处理文本共享https://github.com/jberlana/JBWhatsAppActivity

Answer 1

使用documentationInteractionController 可以做到这一点。 最近我使用下面的代码将图像从我们的应用程序共享到whatsApp、Line、WeChat，但是当你点击WhatsApp图标时，你会从你的应用程序导航WhatsApp应用程序，你必须手动返回你的应用程序。这不会在 ImageSharing 之后再次重定向。

在 .h 文件中：-

@interface ViewController : UIViewController<UIDocumentInteractionControllerDelegate>
{
}

@property(nonatomic,retain) UIDocumentInteractionController *documentationInteractionController;

在 .m 文件中

- (IBAction)bocClick:(UIButton *)sender {


    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,     NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];

    NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:@"savedImage.png"]; //here i am fetched image path from document directory and convert it in to URL and use bellow


    NSURL *imageFileURL =[NSURL fileURLWithPath:getImagePath];
    NSLog(@"imag %@",imageFileURL);

    self.documentationInteractionController.delegate = self;
    self.documentationInteractionController.UTI = @"net.whatsapp.image";
    self.documentationInteractionController = [self setupControllerWithURL:imageFileURL usingDelegate:self];
    [self.documentationInteractionController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];


}

- (UIDocumentInteractionController *) setupControllerWithURL: (NSURL*) fileURL

                                               usingDelegate: (id <UIDocumentInteractionControllerDelegate>) interactionDelegate {



    self.documentationInteractionController =

    [UIDocumentInteractionController interactionControllerWithURL: fileURL];

    self.documentationInteractionController.delegate = interactionDelegate;



    return self.documentationInteractionController;

}
