iOS8 UILocalNotification 增加啟動授權

iOS8 UILocalNotification 增加啟動授權

 

好久沒接入UILocalNotification了，今天接入時發現沒有許可權啟動通知。
錯誤如下：

Attempting to schedule a local notification {fire date = (null), time zone = (null), repeat interval =0, repeat count = UILocalNotificationInfiniteRepeatCount, next firea badge number but haven't received permission from the user to badgethe application

看了下API，原來iOS8增加了啟動授權，需要使用者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啟動時候調用

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions{    // todo ...    [self RegistNotificationSettings];    return YES;}

注意：只要使用者對app授權過了，以後即使刪除再次安裝，也預設為授權了。
