¿Cómo puedo crear una UIActivity
personalizada en iOS?
El motivo por el que deseo esto es agregar un botón Revisar aplicación en una de mis aplicaciones que lleva al usuario a la sección de revisión en la tienda de aplicaciones. ¿Cómo puedo crear una UIActivity
personalizada?
Aquí está mi versión de Swift: necesitaba varias acciones personalizadas, así que creé esta clase. No es necesario para delegados o protocolos.
1. Agregue la clase personalizada
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 Uso en su Controlador de Vista
Lo he adjuntado a un UIBarButtonItem, que llama a la siguiente
@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)
}
Aquí hay un ejemplo de cómo configurar una interfaz de compositor de correo electrónico utilizando el método -activityViewController de UIActivity. Esto muestra cómo colocar un UIKit viewController o su propio viewController personalizado para el propósito que elija. Suplanta el método -performActivity.
#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
Tenga en cuenta que se llama -activityDidFinish desde el delegado del compositor de correo después de que el usuario haya descartado la interfaz de correo electrónico. Esto es necesario para que desaparezca la interfaz UIActivityViewController. Si escribe su propio viewController, necesitará un método delegado al que llame cuando haya terminado y tendrá que hacer que su subclase de UIActivity sea el delegado.
Implementación de Mi Swift 3 basada en DogCoffee:
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()
}
}
Primero, crea los archivos. Elegí mi nombre ActivityViewCustomActivity
Haga que ActivityViewCustomActivity.h se vea así:
#import <UIKit/UIKit.h>
@interface ActivityViewCustomActivity : UIActivity
@end
Haga que ActivityViewCustomActivity.m se vea así:
#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
Así es como se veía mi imagen: Aquí está el .PSD que hice: - Se eliminó el enlace malicioso - Y aquí está el original de 250 px .png http://i.imgur.com/pGWVj.png
Ahora en tu controlador de vista haz esto:
#import "ActivityViewCustomActivity.h"
Y ahora, donde quiera que quiera mostrar su UIActivityViewController
:
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];
}
