Ios 自定义UIActivityViewController

我要创建自定义UIActivityViewController。我创造了它，效果很好。我有一些元素在里面，没问题。现在我把它们放在一行。如何使用两行元素创建UIActivityViewController

现在我的代码是：

 - (id)init

 if (self = [super init])
 {
    FacebookActivity *facebookActivity = [[FacebookActivity alloc]init];
    TwitterActivity *twitterActivity = [[TwitterActivity alloc]init];
    EmailActivity *emailActivity = [[EmailActivity alloc]init];
    OpenInSafariActivity *openInSafari = [[OpenInSafariActivity alloc]init];
    OpenInWebActivity *openInWeb = [[OpenInWebActivity alloc]init];
    CopyLink *copyLink = [[CopyLink alloc]init];

    copyLink.delegate = self;
    facebookActivity.delegate = self;
    twitterActivity.delegate = self;
    emailActivity.delegate = self;
    openInWeb.delegate = self;
    openInSafari.delegate = self;

    self = [self initWithActivityItems:@[emailActivity] applicationActivities:@[openInWeb, openInSafari, facebookActivity, twitterActivity, emailActivity, copyLink]];
    self.view.backgroundColor = [UIColor redColor];

    self.completionHandler = ^(NSString *activityType, BOOL completed)
    {
    };
 }
 return self;

第二个问题是如何设置所有UIActivityViewController元素的底部视图颜色。

在自定义

UIActivity

类的实现中，您需要实现以下类方法：

+ (UIActivityCategory)activityCategory {
    return UIActivityCategoryAction; // or return UIActivityCategoryShare
}

---

返回值定义活动将出现在“活动”视图中的行

UIActivityCategoryShare

将活动放在第一行，

UIActivityCategoryAction

将其放在第二行。
