尝试标记应用程序图标，但尚未获得用户的许可，以标记应用程序：iOS 8 Xcode 6
我正在检查我的应用程序与iOS 8的兼容性，我得到以下login控制台“试图徽章应用程序图标，但没有收到来自用户的权限来标记应用程序” 。 任何人都可以请帮我摆脱这个警告。 是的，我的应用程序显示应用程序图标和TabBar图标上的徽章。
这是我在AppDelegate中做的
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // registering for remote notifications [self registerForRemoteNotification]; return YES; } - (void)registerForRemoteNotification { if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) { UIUserNotificationType types = UIUserNotificationTypeSound | UIUserNotificationTypeBadge | UIUserNotificationTypeAlert; UIUserNotificationSettings *notificationSettings = [UIUserNotificationSettings settingsForTypes:types categories:nil]; [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings]; } else { [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)]; } } #ifdef __IPHONE_8_0 - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings { [application registerForRemoteNotifications]; } #endif 苹果公司为注册通知和使用徽章制作了新的API。
请参阅WWDC 2014会话video： https ： //developer.apple.com/videos/wwdc/2014/ ？ id = 713 ， http : //asciiwwdc.com/2014/sessions/713 （文本版本）和https：// developer .apple.com / library / ios / documentation / UIKit / Reference / UIApplication_Class / index.html＃// apple_ref / occ / instm / UIApplication / registerUserNotificationSettings ：
用户可以在设置中更改每个UIUserNotificationType (UIUserNotificationTypeBadge, UIUserNotificationTypeSound, UIUserNotificationTypeAlert)权限。
更换徽章之前，您必须检查权限。
我的AppDelegate中的代码示例：
- (BOOL)checkNotificationType:(UIUserNotificationType)type { UIUserNotificationSettings *currentSettings = [[UIApplication sharedApplication] currentUserNotificationSettings]; return (currentSettings.types & type); } - (void)setApplicationBadgeNumber:(NSInteger)badgeNumber { UIApplication *application = [UIApplication sharedApplication]; if(SYSTEM_VERSION_LESS_THAN(@"8.0")) { application.applicationIconBadgeNumber = badgeNumber; } else { if ([self checkNotificationType:UIUserNotificationTypeBadge]) { NSLog(@"badge number changed to %d", badgeNumber); application.applicationIconBadgeNumber = badgeNumber; } else { NSLog(@"access denied for UIUserNotificationTypeBadge"); } } } #define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
currentUserNotificationSettings方法在UI应用程序实例中可用，并将为您提供最新的用户通知首选项。
使用徽章号码：
[self setApplicationBadgeNumber:0];
代替
application.applicationIconBadgeNumber = 0;
您可以使用
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000 if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]) { [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]]; [[UIApplication sharedApplication] registerForRemoteNotifications]; } else { [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)]; } #else [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)]; #endif
我遇到了这个答案，同时在Swift中寻找解决scheme。 我做了以下（假设iOS 8）：
UIApplication.sharedApplication().registerUserNotificationSettings(UIUserNotificationSettings(forTypes: UIUserNotificationType.Sound | UIUserNotificationType.Alert | UIUserNotificationType.Badge, categories: nil)) UIApplication.sharedApplication().registerForRemoteNotifications()
而不是检查IOS版本，我会检查UIUserNotificationSettings是否存在，并注册BadgeType，就像我们用远程通知一样。
Class userNotification = NSClassFromString(@"UIUserNotificationSettings"); if (userNotification) { UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil]; [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings]; }
如果你想使用本地通知使用下面的代码：
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000 [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]]; [[UIApplication sharedApplication] registerForRemoteNotifications]; #else [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)]; #endif
iOS 8有一个名为registerUserNotificationSettings:的应用程序方法registerUserNotificationSettings: 部分文档说：“如果您的应用程序在后台显示警报，播放声音或标记其图标，则必须在启动周期中调用此方法，以便请求以这些方式提醒用户的权限。
您可以使用
if(SYSTEM_VERSION_LESS_THAN(@"8.0")) { [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)]; } else { [[UIApplication sharedApplication] registerForRemoteNotifications]; } .... #define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
对于推送通知，我认为这将解决它，在我的情况下，在模拟器我得到这个警告，因为它不支持推，我用户拒绝的权限，而不是你会有这样的警告。 谢谢。
对于“swifters”上面的代码：
final func checkNotificationType(type : UIUserNotificationType) -> Bool { let application = UIApplication.sharedApplication() if application.respondsToSelector(Selector("registerUserNotificationSettings:")) { // iOS8 and above let currentSettings : UIUserNotificationSettings = application.currentUserNotificationSettings() let types = currentSettings.types return types.rawValue & type.rawValue > 0 }else{ return true } }
+ (BOOL)canBadgeTheApp { BOOL canBadgeTheApp; if ([UIDevice currentDevice].systemVersion.doubleValue >= 8) { UIUserNotificationType types = [[[UIApplication sharedApplication] currentUserNotificationSettings] types]; canBadgeTheApp = ((types & UIRemoteNotificationTypeBadge) != 0); } else { canBadgeTheApp = YES; } return canBadgeTheApp; }
你唯一需要的是
if (floor(NSFoundationVersionNumber) >= NSFoundationVersionNumber_iOS_8_0) { // here you go with iOS 8 } else { }
