iOSでカスタムUIActivityを作成するにはどうすればよいですか？

IOSでカスタムUIActivityを作成するにはどうすればよいですか？

これが欲しいのは、アプリの1つに[アプリのレビュー]ボタンを追加して、ユーザーをApp Storeのレビューセクションに移動させるためです。このようなカスタムUIActivityを作成するにはどうすればよいですか？

まず、ファイルを作成します。私の名前をActivityViewCustomActivityとすることにしました

ActivityViewCustomActivity.hを次のようにします。

#import <UIKit/UIKit.h>

@interface ActivityViewCustomActivity : UIActivity

@end

ActivityViewCustomActivity.mを次のようにします。

#import "ActivityViewCustomActivity.h"

@implementation ActivityViewCustomActivity

- (NSString *)activityType
{
    return @"yourappname.Review.App";
}

- (NSString *)activityTitle
{
    return @"Review App";
}

- (UIImage *)activityImage
{  
    // Note: These images need to have a transparent background and I recommend these sizes:
    // iPadShare@2x should be 126 px, iPadShare should be 53 px, iPhoneShare@2x should be 100 
    // px, and iPhoneShare should be 50 px. I found these sizes to work for what I was making.

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    {
        return [UIImage imageNamed:@"iPadShare.png"];
    }
    else
    {
        return [UIImage imageNamed:@"iPhoneShare.png"];
    }
}

- (BOOL)canPerformWithActivityItems:(NSArray *)activityItems
{
    NSLog(@"%s", __FUNCTION__);
    return YES;
}

- (void)prepareWithActivityItems:(NSArray *)activityItems
{
    NSLog(@"%s",__FUNCTION__);
}

- (UIViewController *)activityViewController
{
    NSLog(@"%s",__FUNCTION__);
    return nil;
}

- (void)performActivity
{   
    // This is where you can do anything you want, and is the whole reason for creating a custom 
    // UIActivity

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms-apps://ax.iTunes.Apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?type=Purple+Software&id=yourappid"]];
    [self activityDidFinish:YES];
}

@end

これが私の画像の外観です：ここに私が作成した.PSDがあります--悪意のあるリンクが削除されました-そして、ここに元の250ピクセルの.png http://i.imgur.com/pGWVj.png

View Controllerでこれを行います：

#import "ActivityViewCustomActivity.h"

そして今、あなたのUIActivityViewControllerを表示したい場所：

   NSString *textItem = @"Check out the yourAppNameHere app: iTunes http link to your app here";
   UIImage *imageToShare = [UIImage imageNamed:@"anyImage.png"];

   NSArray *items = [NSArray arrayWithObjects:textItem,imageToShare,nil];

   ActivityViewCustomActivity *aVCA = [[ActivityViewCustomActivity alloc]init];

   UIActivityViewController *activityVC =
   [[UIActivityViewController alloc] initWithActivityItems:items
                                                  applicationActivities:[NSArray arrayWithObject:aVCA]];

   activityVC.excludedActivityTypes = @[UIActivityTypePostToWeibo, UIActivityTypeAssignToContact, UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeSaveToCameraRoll];

   activityVC.completionHandler = ^(NSString *activityType, BOOL completed)
   {
        NSLog(@"ActivityType: %@", activityType);
        NSLog(@"Completed: %i", completed);
   };

   if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
   {
      self.popoverController = [[UIPopoverController alloc] initWithContentViewController:activityVC];

      CGRect rect = [[UIScreen mainScreen] bounds];

      [self.popoverController
                     presentPopoverFromRect:rect inView:self.view
                     permittedArrowDirections:0
                     animated:YES];
   }
   else
   {
       [self presentViewController:activityVC animated:YES completion:nil];
   }

Swiftバージョン-複数のカスタムアクションが必要なため、このクラスを作成しました。デリゲートやプロトコルは不要です。

1。カスタムクラスを追加

class ActivityViewCustomActivity: UIActivity {

    var customActivityType = ""
    var activityName = ""
    var activityImageName = ""
    var customActionWhenTapped:( (Void)-> Void)!

    init(title: String, imageName:String, performAction: (() -> ()) ) {
        self.activityName = title
        self.activityImageName = imageName
        self.customActivityType = "Action \(title)"
        self.customActionWhenTapped = performAction
        super.init()
    }

    override func activityType() -> String? {
        return customActivityType
    }

    override func activityTitle() -> String? {
        return activityName
    }

    override func activityImage() -> UIImage? {
        return UIImage(named: activityImageName)
    }

    override func canPerformWithActivityItems(activityItems: [AnyObject]) -> Bool {
        return true
    }

    override func prepareWithActivityItems(activityItems: [AnyObject]) {
        // nothing to prepare
    }

    override func activityViewController() -> UIViewController? {
        return nil
    }

    override func performActivity() {
        customActionWhenTapped()
    }
}

2 View Controllerで使用

次を呼び出すUIBarButtonItemに添付しました

@IBAction func actionButtonPressed(sender: UIBarButtonItem) {

    var sharingItems = [AnyObject]() // nothing to share...

    let myCustomActivity = ActivityViewCustomActivity(title: "Mark Selected", imageName: "removePin") {
        println("Do something")
    }

    let anotherCustomActivity = ActivityViewCustomActivity(title: "Reset All", imageName: "reload") {
        println("Do something else")
    }

    let activityViewController = UIActivityViewController(activityItems:sharingItems, applicationActivities:[myCustomActivity, anotherCustomActivity])

    activityViewController.excludedActivityTypes = [UIActivityTypeMail, UIActivityTypeAirDrop, UIActivityTypeMessage, UIActivityTypeAssignToContact, UIActivityTypePostToFacebook, UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeSaveToCameraRoll]

    activityViewController.popoverPresentationController?.barButtonItem = sender

    self.presentViewController(activityViewController, animated: true, completion: nil)
}

私のSwift DogCoffeeに基づいた実装：

class ActivityViewCustomActivity: UIActivity {

    // MARK: Properties

    var customActivityType: UIActivityType
    var activityName: String
    var activityImageName: String
    var customActionWhenTapped: () -> Void


    // MARK: Initializer

    init(title: String, imageName: String, performAction: @escaping () -> Void) {
        self.activityName = title
        self.activityImageName = imageName
        self.customActivityType = UIActivityType(rawValue: "Action \(title)")
        self.customActionWhenTapped = performAction
        super.init()
    }



    // MARK: Overrides

    override var activityType: UIActivityType? {
        return customActivityType
    }



    override var activityTitle: String? {
        return activityName
    }



    override class var activityCategory: UIActivityCategory {
        return .share
    }



    override var activityImage: UIImage? {
        return UIImage(named: activityImageName)
    }



    override func canPerform(withActivityItems activityItems: [Any]) -> Bool {
        return true
    }



    override func prepare(withActivityItems activityItems: [Any]) {
        // Nothing to prepare
    }



    override func perform() {
        customActionWhenTapped()
    }
}

以下に、UIActivityの-activityViewControllerメソッドを使用して、メールcomposerインターフェースを配置する例を示します。これは、UIKit viewControllerまたは独自のカスタムviewControllerを選択した目的に合わせて配置する方法を示します。 -performActivityメソッド。

#import <MessageUI/MessageUI.h>
#import <UIKit/UIKit.h>

@interface EPSuggestionsActivity : UIActivity <MFMailComposeViewControllerDelegate>

@end

@implementation EPSuggestionsActivity

....

- (UIViewController *)activityViewController{

    MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    picker.mailComposeDelegate = self;

    NSString *emailAddress = @"[email protected]";
    NSArray *toRecipients = @[emailAddress];
    [picker setToRecipients:toRecipients];
    [picker setSubject:@"Suggestions"];

    return picker;
}

#pragma mark - MFMailComposeViewControllerDelegate Method

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error  {

    [self activityDidFinish:YES];   //  Forces the activityViewController to be dismissed
}

@end

-activityDidFinishは、ユーザーが電子メールインターフェイスを閉じた後、メールcomposerデリゲートから呼び出されます。UIActivityViewControllerインターフェイスを非表示にするには、これが必要です。独自のviewControllerを作成する場合は、終了時に呼び出すデリゲートメソッド。UIActivityのサブクラスをデリゲートにする必要があります。
