iOS本地通知（iOS8改变）

dispatch_async(dispatch_get_main_queue(), ^{

UILocalNotification * localNotification = [[UILocalNotification
alloc] init];

if (localNotification)
{
localNotification.fireDate= [[[NSDate
alloc] init]
dateByAddingTimeInterval:3];
localNotification.timeZone=[NSTimeZone
defaultTimeZone];
localNotification.alertBody =
@"客户端有新的版本,点击到App
Store升级。";
localNotification.alertAction =
@"升级";
localNotification.soundName =
@"";
[application
scheduleLocalNotification:localNotification];
}
});

iOS8中需要在 - (BOOL)application:(UIApplication
*)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 方法下添加如下代码：

if ([UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)]){
UIUserNotificationType type = UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound;
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:type categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
}
