ios – 调试输出提示我应该申请应用程序徽章权限
我做了一个非常简单的应用程序,可以在后台运行一个计时器运行。如果应用程序仍在后台并且计时器结束,它将发送本地通知并将应用程序徽章设置为1.当我启动应用程序时,我总是清除它。我注意到安装Xcode 6后,每次启动该应用程序时都会收到此消息:
“尝试标记应用程序图标但尚未获得用户对应用程序的许可” 很明显,文字是由我的应用程式产生,将徽章设为0,以将其清除。我在哪里设置这些权限或要求他们?现在被认为是推送通知吗? 问题已经解决,答案在下面发布。最重要的是,您需要从用户那里获得任何通知的确认,而以前只有推送通知才是真实的。 解决方法
我最终没有使用应用程序徽章,我放弃了我在这里平均发布的初始代码段。由于仍然有人阅读和评论这个问题,我将在这里添加我的工作当前解决方案。它包含对iOS7的检查,但我不使用回调方法。此外,此版本不仅要求应用程序徽章权限。
解 UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge categories:nil]; [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings]; 这是我现在用的 .h文件 #import <Foundation/Foundation.h> @interface NotificationPermissionHandler : NSObject + (void)checkPermissions; + (bool)canSendNotifications; @end .m文件: #import "NotificationPermissionHandler.h" @implementation NotificationPermissionHandler static const UIUserNotificationType USER_NOTIFICATION_TYPES_REQUIRED = UIUserNotificationTypeAlert | UIUserNotificationTypeSound; static const UIRemoteNotificationType REMOTE_NOTIFICATION_TYPES_REQUIRED = UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound; + (void)checkPermissions; { bool isIOS8OrGreater = [[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]; if (!isIOS8OrGreater) { [NotificationPermissionHandler iOS7AndBelowPermissions]; return; } [NotificationPermissionHandler iOS8AndAbovePermissions]; } + (void)iOS7AndBelowPermissions { [[UIApplication sharedApplication] registerForRemoteNotificationTypes:REMOTE_NOTIFICATION_TYPES_REQUIRED]; } + (void)iOS8AndAbovePermissions; { if ([NotificationPermissionHandler canSendNotifications]) { return; } UIUserNotificationSettings* requestedSettings = [UIUserNotificationSettings settingsForTypes:USER_NOTIFICATION_TYPES_REQUIRED categories:nil]; [[UIApplication sharedApplication] registerUserNotificationSettings:requestedSettings]; } + (bool)canSendNotifications; { UIApplication *application = [UIApplication sharedApplication]; bool isIOS8OrGreater = [application respondsToSelector:@selector(currentUserNotificationSettings)]; if (!isIOS8OrGreater) { // We actually just don't know if we can,no way to tell programmatically before iOS8 return true; } UIUserNotificationSettings* notificationSettings = [application currentUserNotificationSettings]; bool canSendNotifications = notificationSettings.types == USER_NOTIFICATION_TYPES_REQUIRED; return canSendNotifications; } @end 这是我的第一个解决方案 我把它作为初步讨论的参考。此代码未被维护。 UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge]; [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings]; 您也可以通过以下方式将权限叠加到一个请求中: UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil]; [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings]; 此外,从iOS 8起,可以确定用户允许哪种警报: UIUserNotificationSettings* notificationSettings = [[UIApplication sharedApplication] currentUserNotificationSettings]; if (notificationSettings.types == UIUserNotificationTypeBadge) { // change the badge } 我最终使用这个代码: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; if (![defaults objectForKey:@"first_run"]) { [self setDefaults]; } [self askAlertPermissions]; if ([self canChangeBadge]) { [self setBadge:0]; } return YES; } - (void)setDefaults; { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [defaults setObject:[NSNumber numberWithBool:NO] forKey:@"alerts_allowed"]; [defaults setObject:[NSDate date] forKey:@"first_run"]; // More defaults if needed [defaults synchronize]; } - (void)askAlertPermissions; { UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil]; [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings]; } // This will be called only after confirming your settings - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings; { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; // There is also a built in method to find out if the user has appropriate settings,you might want to use that instead if you just want to know what the setting is [defaults setObject:[NSNumber numberWithBool:YES] forKey:@"alerts_allowed"]; } - (bool)canChangeBadge; { UIUserNotificationSettings* notificationSettings = [[UIApplication sharedApplication] currentUserNotificationSettings]; return notificationSettings.types == UIUserNotificationTypeBadge; } 更多阅读: https://developer.apple.com/library/prerelease/ios/releasenotes/General/WhatsNewIniOS/Articles/iOS8.html https://developer.apple.com/library/prerelease/ios/documentation/UIKit/Reference/UIApplication_Class/index.html#//apple_ref (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
