本文将带你了解IOS开发入门ios 消息推送详情，希望本文对大家学IOS有所帮助。

消息推送流程

手机系统会一直保持与苹果APNs一个通信

当打开App时候，会从苹果Apns得到一个toKen

发送toKen到后台服务器

服务器发送这个toKen 和 推送数据给苹果APNs   （以为push通道是由苹果维护的一个唯一的通道）

苹果APNs得到后再根据这个toKen推送得到的消息给我们的ios设备

我们得到toKen后就知道是哪个APP的推送内容了

消息推送（以V8.0+为例子）（搭建push环境）

- (BOOL)application:(UIApplication *)application   didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

//读取系统版本，判断是否大于8.0

if([[[UIDevice currentDevice] systemVersion]   floatValue] >=8.0) {

//首先向用户询问push的权限，向用户申请权限

UIUserNotificationSettings* setting =   [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge |   UIUserNotificationTypeSound | UIUserNotificationTypeAlert   categories:nil];

[[UIApplication   sharedApplication] registerUserNotificationSettings:setting];

}else{

[[UIApplication sharedApplication]   registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |   UIRemoteNotificationTypeSound |   UIRemoteNotificationTypeAlert)];

}

}

//用户同意之后回调，去注册DeviceToken

- (void)application:(UIApplication *)application   didRegisterUserNotificationSettings:(nonnull UIUserNotificationSettings   *)notificationSettings{

[[UIApplication   sharedApplication] registerForRemoteNotifications];

}

//注册成功回调，得到DeviceToken

- (void)application:(UIApplication *)application   didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)aDeviceToken   {

DLog(@“succeed regist remote   notification");

NSString*   tokenStr = [NSString stringWithFormat:@"%@",   aDeviceToken];

tokenStr = [tokenStr   stringByReplacingOccurrencesOfString:@" "   withString:@""];

tokenStr =   [tokenStr stringByReplacingOccurrencesOfString:@"<"   withString:@""];

tokenStr =   [tokenStr stringByReplacingOccurrencesOfString:@">"   withString:@""];

//向服务器发送

}

//注册失败回调

-   (void)application:(UIApplication *)application   didFailToRegisterForRemoteNotificationsWithError:(NSError *)error   {

DLog(@"failed regist remote   notification %@ ", error);

}

//当接收到远程通知回调

-   (void)application:(UIApplication *)application   didReceiveRemoteNotification:(NSDictionary *)userInfo {

NSDictionary *apsDictionary = [userInfo   objectForKey:@"aps"];

//解析JSon

/*

具体处理。。。

if（...）{

跳转某个controller。。。

}

*/

}

消息推送（本地推送）

@property (nonatomic, retain) UILocalNotification   *localNotification;

-   (void)backGround{

_localNotification =   [UILocalNotification new];

//多久以后提示用户

_localNotification.fireDate = [NSDate   dateWithTimeIntervalSinceNow:5];

_localNotification.alertBody =   @"你都走了5秒钟了";

_localNotification.alertTitle =   @"你妹的!";

_localNotification.userInfo   = @{@"key":@"value"};

[[UIApplication sharedApplication]   scheduleLocalNotification:_localNotification];

}

-   (void)foreGround{

[[UIApplication   sharedApplication]   cancelLocalNotification:_localNotification];

}

-   (void)viewDidLoad

{

[[NSNotificationCenter defaultCenter]   addObserver:self selector:@selector(backGround)   name:UIApplicationDidEnterBackgroundNotification object:nil];

[[NSNotificationCenter defaultCenter]   addObserver:self selector:@selector(foreGround)   name:UIApplicationWillEnterForegroundNotification object:nil];

}
