好久沒接入UILocalNotification了,今天接入時發現沒有權限啓動通知。
錯誤如下:
Attempting to schedule a local notification <UIConcreteLocalNotification:
0x174178540>{fire date = (null), time zone = (null), repeat interval =
0, repeat count = UILocalNotificationInfiniteRepeatCount, next fire
a badge number but haven't received permission from the user to badge
the application
看了下API,原來iOS8增加了啓動授權,需要用戶同意下才能註冊通知。
添加如下代碼:
- (void)RegistNotificationSettings
{
float sysVersion=[[UIDevice currentDevice]systemVersion].floatValue;
if (sysVersion>=8.0) {
UIUserNotificationType type = UIUserNotificationTypeBadge | UIUserNotificationTypeAlert | UIUserNotificationTypeSound;
UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:type categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:setting];
}
}
你可以在註冊通知之前調用,也可以在app啓動時候調用
- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
// todo ...
[self RegistNotificationSettings];
return YES;
}
注意:只要用戶對app授權過了,以後即使刪除再次安裝,也默認爲授權了。
