iOS推送

很早在自己的一款项目也做过推送，并且是由自己生成证书等流程。这部分内容网上大都有，这里不多做细说。

自己目前的项目这次也需要做一个推送，点击推送后到达一个目标界面。

当然，推送使用的是第三方的sdk，网上的第三方sdk一大堆，随便摘几个来用就好，这里就不帮他们做广告了。

略过一大堆，直接开始说配置完成的操作。

创建推送管理类，负责推送的初始化、注册、开始、停止、上传到服务器，保存内容等操作。

<span style="color:#999999;">#import <Foundation/Foundation.h>@interface PushHelper : NSObject#pragma mark -#pragma mark 单例/*! *  创建推送管理类 * *  @return 推送管理类 */+ (instancetype)sharedPushHelper;#pragma mark -#pragma mark 注册/*! *  推送注册 */- (void)registerRemoteNotification;/*! *  开始个推 */- (void)beginGexinSdk;/*! *  结束个推 */- (void)endGexinSdk;/*! *  注册设备号 * *  @param deviceToken 设备号 */- (void)registerDeviceToken:(NSString *)deviceToken;#pragma mark -#pragma mark 界面/*! *  存储推送过来的内容 */@property (nonatomic, strong) NSString *bodyContent;@end</span>

具体实现不详细写，列出几个重点。

<span style="color:#999999;">#pragma mark -#pragma mark 单例/*! *  获取推送管理类单例 * *  @return 推送管理类 */+ (instancetype)sharedPushHelper {    static PushHelper* sharedInstance = nil;    static dispatch_once_t onceToken;    dispatch_once(&onceToken, ^{        sharedInstance = [[super allocWithZone:NULL] init];    });    return sharedInstance;}#pragma mark -#pragma mark 推送注册/*! *  注册apns */- (void)registerRemoteNotification {#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_8_0    if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_7_1) {        UIUserNotificationSettings *uns = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound) categories:nil];        [[UIApplication sharedApplication] registerUserNotificationSettings:uns];    } else {#endif        UIRemoteNotificationType apn_type = (UIRemoteNotificationType)(UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeSound|UIRemoteNotificationTypeBadge);        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:apn_type];#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_8_0    }#endif}</span>

<span style="color:#999999;">#pragma mark -#pragma mark GexinSdkDelegate/*! *  个推注册返回 * *  @param clientId 客户端id */- (void)GexinSdkDidRegisterClient:(NSString *)clientId {    NSLog(@"clientId %@", clientId);    _sdkStatus = SdkStatusStarted;    self.clientId = clientId;    [self uploadClientId];}/*! *  收到个推消息 * *  @param payloadId 推送消息id *  @param appId     应用id */- (void)GexinSdkDidReceivePayload:(NSString *)payloadId fromApplication:(NSString *)appId {    NSLog(@"payloadId %@ appId %@", payloadId, appId);    NSData *payload = [_gexinPusher retrivePayloadById:payloadId];    NSString *payloadMsg = nil;    if (payload) {        payloadMsg = [[NSString alloc] initWithBytes:payload.bytes                                              length:payload.length                                            encoding:NSUTF8StringEncoding];        NSLog(@"payloadMsg %@", payloadMsg);        id obj = [NSJSONSerialization JSONObject:payloadMsg];        if ([obj isKindOfClass:[NSDictionary class]]) {            [[NSNotificationCenter defaultCenter] postNotificationName:@"InfoRemoteNotification" object:nil userInfo:obj];        }    }}/*! *  发送上行消息结果反馈 * *  @param messageId 消息id *  @param result    上传结果 */- (void)GexinSdkDidSendMessage:(NSString *)messageId result:(int)result {    NSLog(@"Received sendmessage:%@ result:%d", messageId, result);}/*! *  个推错误报告，集成步骤发生的任何错误都在这里通知，如果集成后，无法正常收到消息，查看这里的通知。 * *  @param error 错误详情 */- (void)GexinSdkDidOccurError:(NSError *)error {    NSLog(@">>>[GexinSdk error]:%@", [error localizedDescription]);}</span>

为使用做准备，之后操作基本都是在AppDelegate

说明：当一个应用程序成功的注册一个推送服务（APS）发送到委托去...

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {    NSString *token = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];    token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];    NSLog(@"deviceToken:%@", token);        [[PushHelper sharedPushHelper] registerDeviceToken:token];//注册token}

说明：当 APS无法成功的完成向程序进程推送时发送到委托去...

- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {    NSLog(@"Failed to get token, error:%@", error);        [[PushHelper sharedPushHelper] registerDeviceToken:@""];}

说明：当一个运行着的应用程序收到一个远程的通知发送到委托去...

<span style="color:#c0c0c0;">- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {    NSLog(@"userInfo %@", userInfo);    [[PushHelper sharedPushHelper] setBodyContent:userInfo]; //设置内容到自身，看你们怎么设置了}</span>

//成功注册registerUserNotificationSettings:后，回调的方法

//该方法为iOS8之后的方法可以command+点击该方法进入。

<span style="color:#c0c0c0;">#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_8_0- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {    [application registerForRemoteNotifications];}#endif</span>

程序在启动时候会调用该方法，一般情况下，launchOptions为nil。

假如我们程序没有加载，这时候我们突然接收到一条消息，点击推送这时候并不会进入

<span style="color:#c0c0c0;">- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo</span>

该方法，而是进入didFinishLaunchingWithOptions这个方法，而这时候，launchOptions并不会为空，并且有launchOptions字典中存储者userInfo的资料，我们只需要将其取出。

NSDictionary* dictionary = [launchOptionsobjectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];

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

下面这些方法，也是很有作用的一些方法，可以作为参考，如果App有其他特殊的需要。

-(void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void (^)())completionHandler
{
//在没有启动本App时，收到服务器推送消息，下拉消息会有快捷回复的按钮，点击按钮后调用的方法，根据identifier来判断点击的哪个按钮
}

-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
//收到本地推送消息后调用的方法
NSLog(@"%@",notification);
}
-(void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void (^)())completionHandler
{
//在非本App界面时收到本地消息，下拉消息会有快捷回复的按钮，点击按钮后调用的方法，根据identifier来判断点击的哪个按钮，notification为消息内容
NSLog(@"%@----%@",identifier,notification);
completionHandler();//处理完消息，最后一定要调用这个代码块
}
