获取推送通知的设备令牌
获取推送通知的设备令牌
提问于 2012-01-10 12:54:33
我正在处理推送通知。我编写了以下代码来获取设备令牌。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
// Add the view controller's view to the window and display.
[self.window addSubview:viewController.view];
[self.window makeKeyAndVisible];
NSLog(@"Registering for push notifications...");
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
return YES;
}
- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
NSString *str = [NSString stringWithFormat:@"Device Token=%@",deviceToken];
NSLog(@"This is device token%@", deviceToken);
}
- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err {
NSString *str = [NSString stringWithFormat: @"Error: %@", err];
NSLog(@"Error %@",err);
}我可以在设备上成功运行应用程序，但无法在控制台上获取设备id。
我对认证和配置配置文件没有任何问题。

下面的代码用于检索设备令牌。
// Prepare the Device Token for Registration (remove spaces and < >)
NSString *devToken = [[[[deviceToken description]
stringByReplacingOccurrencesOfString:@"<"withString:@""]
stringByReplacingOccurrencesOfString:@">" withString:@""]
stringByReplacingOccurrencesOfString: @" " withString: @""];
NSString *str = [NSString
stringWithFormat:@"Device Token=%@",devToken];
UIAlertView *alertCtr = [[[UIAlertView alloc] initWithTitle:@"Token is " message:devToken delegate:self cancelButtonTitle:nil otherButtonTitles: nil] autorelease];
[alertCtr show];
NSLog(@"device token - %@",str);Stack Overflow用户

从iOS 13开始，苹果改变了[deviceToken description]的输出。现在它就像这样的{length=32,bytes=0x0b8823aec3460e1724e795cba45d22e8...af8c09f971d0dabc}，这对于设备令牌是不正确的。
我建议使用以下代码片段来解决一个问题：
+ (NSString *)stringFromDeviceToken:(NSData *)deviceToken {
NSUInteger length = deviceToken.length;
if (length == 0) {
return nil;
}
const unsigned char *buffer = deviceToken.bytes;
NSMutableString *hexString = [NSMutableString stringWithCapacity:(length * 2)];
for (int i = 0; i < length; ++i) {
[hexString appendFormat:@"%02x", buffer[i]];
}
return [hexString copy];
}它将适用于iOS13及更低版本。

如果您仍然无法获得设备令牌，请尝试输入以下代码以注册您的设备以接收推送通知。
它也可以在ios8或更多平台上运行。
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000
if ([UIApplication respondsToSelector:@selector(registerUserNotificationSettings:)]) {
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeAlert|UIUserNotificationTypeSound
categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
[[UIApplication sharedApplication] registerForRemoteNotifications];
} else {
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
UIRemoteNotificationTypeBadge |
UIRemoteNotificationTypeAlert |
UIRemoteNotificationTypeSound];
}
#else
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
UIRemoteNotificationTypeBadge |
UIRemoteNotificationTypeAlert |
UIRemoteNotificationTypeSound];
