即时通讯目前与“地区”的示例代码工作: https://developer.apple.com/library/ios/#samplecode/Regions/Introduction/Intro.h TML#// apple_ref/DOC/UID/DTS40010726-介绍,DontLinkElementID_2地区根据本地通知
我想采取这一步,当用户退出该区域时可以生成或触发通知(可以为两个输入&退出,我不介意,无论什么对于初始实现来说都是最简单的)。
我一直在寻找CLLocation类参考,位置感知编程指南和本地和推送通知编程指南。而且即时通讯信息过载。
非常感谢:)
编辑:我想我可能有一个想法,解决了这个问题: 在RegionsViewController实现文件中有这样的:
- (void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region {
NSString *event = [NSString stringWithFormat:@"didExitRegion %@ at %@", region.identifier, [NSDate date]];
[self updateWithEvent:event];
}
因为我想实现一个地方通知当用户退出指定区域边界,我输入此:
- (void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region {
NSString *event = [NSString stringWithFormat:@"didExitRegion %@ at %@", region.identifier, [NSDate date]];
[self updateWithEvent:event];
//implement local notification:
UIApplication *app = [UIApplication sharedApplication];
UILocalNotification *notification = [[UILocalNotification alloc] init];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
if (notification == nil)
return;
notification.alertBody = [NSString stringWithFormat:@"Did You Lock Your House?"];
notification.alertAction = @"Lock House";
notification.soundName = UILocalNotificationDefaultSoundName;
notification.applicationIconBadgeNumber = 1;
[app presentLocalNotificationNow:notification];
[notification release];
}
可能有人建议我是否该是正确的,还是有任何建议? (道歉为格式不佳)
