Gluon Mobile Share按钮实现-Java 学习之路

Gluon Mobile是否有实施分享按钮的指导？我的目标是能够共享包含手机上不同应用程序链接的字符串 . At the moment, I need this only for the iOS implementation. 我能够找到这个link，它提供了一种在Objective-C中执行此操作的简单方法：

- (IBAction)shareButton:(UIBarButtonItem *)sender
{
    NSString *textToShare = @"Look at this awesome website for aspiring iOS Developers!";
    NSURL *myWebsite = [NSURL URLWithString:@"http://www.codingexplorer.com/"];

    NSArray *objectsToShare = @[textToShare, myWebsite];

    UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];

    NSArray *excludeActivities = @[UIActivityTypeAirDrop,
                                   UIActivityTypePrint,
                                   UIActivityTypeAssignToContact,
                                   UIActivityTypeSaveToCameraRoll,
                                   UIActivityTypeAddToReadingList,
                                   UIActivityTypePostToFlickr,
                                   UIActivityTypePostToVimeo];

    activityVC.excludedActivityTypes = excludeActivities;

    [self presentViewController:activityVC animated:YES completion:nil];
}

看看Gluon网站上的GoNative应用程序示例，似乎我可以使用上面的代码片段作为本机iOS代码 . 我是否必须更新ios build gradle以考虑上面第一个链接中提到的UIActivity类？

Update*

我已经能够根据这个问题的帮助here让这个工作 .

但是，在尝试安装本机库时，我收到此错误，这是可以理解的，因为 self 在代码范围内是未知的 . 我怎么能这样做？实例化一个弹出窗口或对话框并将 activityVC 传递给它？

所以我能够使用互联网上的示例（如上所示）解决这个问题，同时浏览条形码扫描服务的现有代码 . 我遇到上述代码时遇到的问题是无法找到当前的视图控制器 . 但是，查看Barcode Scan的位桶源，我能够使用以下代码获取根视图：

if(![[UIApplication sharedApplication] keyWindow])
{
    NSLog(@"key window was nil");
    return;
}

// get the root view controller
UIViewController *rootViewController = [[[UIApplication sharedApplication] keyWindow] rootViewController];
if(!rootViewController)
{
    NSLog(@"rootViewController was nil");
    return;
}

然后在我放入问题的代码段中，将 self 替换为 rootViewController ：

[rootViewController presentViewController:activityVC animated:YES completion:nil];

这会导致修改后的代码段：

#import <UIKit/UIKit.h>

#include "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/JavaVM.framework/Versions/A/Headers/jni.h"

JNIEXPORT void JNICALL     Java_com_gluonhq_charm_down_plugins_ios_IOSShareService_shareMessage
(JNIEnv *env, jclass jClass, jstring jMessage) {

    if(![[UIApplication sharedApplication] keyWindow])
    {
        NSLog(@"key window was nil");
        return;
    }

    // get the root view controller
    UIViewController *rootViewController = [[[UIApplication sharedApplication] keyWindow] rootViewController];
    if(!rootViewController)
    {
        NSLog(@"rootViewController was nil");
        return;
    }

    NSString *textToShare = @"Check out this site!";
    NSURL *myWebsite = [NSURL URLWithString:@"http://www.google.com/"];

    NSArray *objectsToShare = @[textToShare, myWebsite];

    UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];

    NSArray *excludeActivities = @[UIActivityTypeAirDrop,
                                   UIActivityTypePrint,
                                   UIActivityTypeAssignToContact,
                                   UIActivityTypeSaveToCameraRoll,
                                   UIActivityTypeAddToReadingList,
                                   UIActivityTypePostToFlickr,
                                   UIActivityTypePostToVimeo];

    activityVC.excludedActivityTypes = excludeActivities;

   [rootViewController presentViewController:activityVC animated:YES completion:nil];

}

Note I followed the GoNative application to generate my objective-c/ios files correctly.

这导致最小的功能共享实现 only because I don't have Facebook installed on the IPhone simulator.
