ios8下LocationManager及Nsnotification使用

location service使用

ios8之前locationservice在应用开启
self.locationManager = [[CLLocatonManager alloc] init]
[self.locationManager startUpdatingLocation];
在iOS8上需要加上kCLAuthorizationStatusAuthorizedAlways，在app中的info.plist中添加NSLocationAlwaysUsageDescription 或者 NSLocationWhenInUseUsageDescription其中一个key，value的值可以任意填写，会在请求获取位置的对话框中显示
请求获取位置权限

// iOS 8 - request location services via requestWhenInUseAuthorization.

if ([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
[self.locationManager requestWhenInUseAuthorization];
} else {
// iOS 7 - We can't use requestWhenInUseAuthorization -- we'll get an unknown selector crash!
// Instead, you just start updating location, and the OS will take care of prompting the user
// for permissions.
[self.locationManager startUpdatingLocation];
}

实现代理方法，当获取到这个权限时
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
{
// We only need to start updating location for iOS 8 -- iOS 7 users should have already
// started getting location updates
if (status == kCLAuthorizationStatusAuthorizedAlways ||
status == kCLAuthorizationStatusAuthorizedWhenInUse) {
[manager startUpdatingLocation];
}
}
2.ios8设置获取通知的权限和之前有所不同

#ifdef __IPHONE_8_0 if(SYSTEM_VERSION_LESS_THAN(@"8.0")){ UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound; [[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes]; } else{ UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil]; [application registerUserNotificationSettings:notificationSettings]; [application registerForRemoteNotifications]; } #else UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound; [[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes];#endif获取remotenotification
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler{ completionHandler(UIBackgroundFetchResultNewData); NSLog(@"remote notifation %@",userInfo);
}

//获取到推送的通知- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{ }

设置setbadgeNumber
- (void)setApplicationBadgeNumber:(NSInteger)badgeNumber{ UIApplication *application = [UIApplication sharedApplication]; #ifdef __IPHONE_8_0 // compile with Xcode 6 or higher (iOS SDK >= 8.0) 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"); } #else // compile with Xcode 5 (iOS SDK < 8.0) application.applicationIconBadgeNumber = badgeNumber; #endif}
