【Objective-C】Unity调用iOS分享界面

相关代码如下

+(void)shareMsg:(NSString *)message addUrl:(NSString *)url imgPath:(NSString *)filePath
{
    NSMutableArray *items = [NSMutableArray new];//创建分享内容List
    [items addObject:message];//添加message到List
    [items addObject:[NSURL URLWithString:url]];//添加URL到List

    UIImage *image = [UIImage imageWithContentsOfFile:filePath];//从filePath获取Image
    if(image != nil)//判断是否存在image
        [items addObject:image];//添加image到list
    
    
    //初始化UI控制器
    UIActivityViewController *activity = [[UIActivityViewController alloc] initWithActivityItems:items applicationActivities:nil];
 
    //为iPad初始化分享界面
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
        activity.popoverPresentationController.sourceView = activity.view;//设置目标弹窗
        //设置弹窗位置以及大小
        activity.popoverPresentationController.sourceRect = CGRectMake( UnityGetGLViewController().view.frame.size.width / 2, UnityGetGLViewController().view.frame.size.height / 2, 1, 1 );
    }
    //显示分享界面
    [UnityGetGLViewController() presentViewController:activity animated:YES completion:nil];
}

注释： 

• filePath：分享图片的本地路径 
• URL：用户点击分享内容时跳转的页面
• 需要为iPad单独设置分享界面的弹窗位置以及大小，否则出错
