问如何将UIImage从iPhone应用程序传递给Apple应用程序

EN

var dict:[NSString : UIImage] = ["image" : yourImage]

- (void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo
              reply:(void (^)(NSDictionary *))reply
{
  reply(@{@"image" : UIImagePNGRepresentation(yourUIImage)});
  // JPEG Representation would of course also work
}

- (IBAction)passUserInfo:(id)sender
{
    NSDictionary *userInfo = @{@"image":[UIImage imageNamed:@"test"]};

    [WKInterfaceController openParentApplication:userInfo reply:^(NSDictionary *replyInfo, NSError *error){
        if ([replyInfo objectForKey:@"success"]) {
            NSLog(@"Sent your data");
        }
    }];// userinfo must be non-nil
}

    - (void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void(^)(NSDictionary *replyInfo))reply
{
    UIImage *image = [userInfo objectForKey:@"image"];

    NSDictionary *replyInfo = @{@"success":@"success",@"error":@""};

    reply(replyInfo);
}
