怎样判断iOS App是通过哪种途径启动的?
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 说明:当应用程序启动时执行,应用程序启动入口。只在应用程序启动时执行一次。application参数用来获取应用程序的状态、变量等,值得注意的是字典参数:(NSDictionary *)launchOptions,该参数存储程序启动的原因。 1.若用户直接启动,lauchOptions内无数据;2.若由其他应用程序通过openURL:启动,则UIApplicationLaunchOptionsURLKey对应的对象为启动URL(NSURL),UIApplicationLaunchOptionsSourceApplicationKey对应启动的源应用程序的bundle ID (NSString); 3.若由本地通知启动,则UIApplicationLaunchOptionsLocalNotificationKey对应的是为启动应用程序的的本地通知对象(UILocalNotification); 4.若由远程通知启动,则UIApplicationLaunchOptionsRemoteNotificationKey对应的是启动应用程序的的远程通知信息userInfo(NSDictionary); 其他key还有UIApplicationLaunchOptionsAnnotationKey,UIApplicationLaunchOptionsLocationKey,UIApplicationLaunchOptionsNewsstandDownloadsKey。 如果要在启动时,做出一些区分,那就需要在下面的代码做处理。 比如:应用可以被某个其它应用调起(作为该应用的子应用),要实现单点登录,那就需要在启动代码的地方做出合理的验证,并跳过登录。 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{ NSURL *url = [options objectForKey:UIApplicationLaunchOptionsURLKey]; if(url) { } NSString *bundleId = [options objectForKey:UIApplicationLaunchOptionsSourceApplicationKey];if(bundleId) { } UILocalNotification * localNotify = [options objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];if(localNotify) { } NSDictionary * userInfo = [options objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];if(userInfo) { } }
根据当前程序的状态,判断当前程序是否进行推送(前台不推送,后台推送)
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
[UMessage didReceiveRemoteNotification:userInfo];
//定制自定的的弹出框
if([UIApplication sharedApplication].applicationState == UIApplicationStateActive) {//程序处于激活状态,不允许推送
[UMessage setAutoAlert:NO];//关闭提示框
}else{ //允许推送
[UMessage didReceiveRemoteNotification:userInfo];
//发送通知
NSNotificationCenter *center = [NSNotificationCenter defaultCenter];
//发送远程通知
[center postNotificationName:@"CYREMOTENOTICATION" object:nil userInfo:userInfo];
}
}
