ios 消息推送详情

消息推送流程

手机会一直保持与苹果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];
