前面几篇文章说了本地推送的相关内容，下面是关于远程推送的。由于推送要服务端进行推，客户端接收，但是有时候不好协调，希望自己本地可以推，方便我们客户端测试。现在推荐一个好用的工具Knuff和NWPusher，本篇文章是用Knuff为例，更多关于Knuff的简介看这篇文章

1、在mac上下载一个Knuff，界面很简单如下这里写图片描述

2、注意设备的token在开发环境下是会变的哦，在删除app之后，会不一样，所以需要注意下，否则收不到推送哦！

点击push之后，该设备就可以收到推送啦，如图

下面看下远程带图片的推送

这里写图片描述

远程带附件的推送需要用到Notification Service Extension 新建一个target，选择Notification Service Extension 这里写图片描述

看到项目中会多出如下文件

这里写图片描述

我们先配制推送的格式，在knuff中

{ "aps":{ "alert":{ "title":"hello",//标题 "body":"this is body",//内容 "type":".jpg"//多媒体的类型，方便后面存储 }, "sound":"default",//推送声音 "badge":1,//app显示的数字 "mutable-content": "1",//附件推送要有这个关键字，否则不行 "my-attachment": "http://upload.univs.cn/2012/0104/1325645511371.jpg",//附件的链接 "userInfo":{ "locatin":"地址：上海浦东", "user":"yuna", }//额外信息 }}

这里写图片描述

在NotificationService.m项目中加上如下代码

#import "NotificationService.h"@interface NotificationService ()@PRoperty (nonatomic, strong) void (^contentHandler)(UNNotificationContent *contentToDeliver);@property (nonatomic, strong) UNMutableNotificationContent *bestAttemptContent;@end@implementation NotificationService- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler { self.contentHandler = contentHandler; self.bestAttemptContent = [request.content mutableCopy]; // Modify the notification content here... NSLog(@"request.content--->%@",request.content); NSDictionary *dict = self.bestAttemptContent.userInfo; NSDictionary *notiDict = dict[@"aps"][@"alert"]; // 可重新修改显示的内容，不重新赋值的话，会显示alert内设置的信息// self.bestAttemptContent.title = [notiDict objectForKey:@"title"];// self.bestAttemptContent.body =[notiDict objectForKey:@"body"]; NSString *mediaUrl = [NSString stringWithFormat:@"%@",dict[@"aps"][@"my-attachment"]]; NSString *mediaType = [NSString stringWithFormat:@"%@",notiDict[@"type"]]; if (!mediaUrl.length) { self.contentHandler(self.bestAttemptContent); } [self loadAttachmentForUrlString:mediaUrl withType:mediaType completionHandle:^(UNNotificationAttachment *attach) { if (attach) { self.bestAttemptContent.attachments = [NSArray arrayWithObject:attach]; } self.contentHandler(self.bestAttemptContent); }];}//下载多媒体附件- (void)loadAttachmentForUrlString:(NSString *)urlStr withType:(NSString *)type completionHandle:(void(^)(UNNotificationAttachment *attach))completionHandler{ __block UNNotificationAttachment *attachment = nil; NSURL *attachmentURL = [NSURL URLWithString:urlStr]; NSURLsession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; [[session downloadTaskWithURL:attachmentURL completionHandler:^(NSURL *temporaryFileLocation, NSURLResponse *response, NSError *error) { if (error != nil) { NSLog(@"%@", error.localizedDescription); } else { NSFileManager *fileManager = [NSFileManager defaultManager]; NSURL *localURL = [NSURL fileURLWithPath:[temporaryFileLocation.path stringByAppendingString:type]]; [fileManager moveItemAtURL:temporaryFileLocation toURL:localURL error:&error]; NSError *attachmentError = nil; attachment = [UNNotificationAttachment attachmentWithIdentifier:type URL:localURL options:nil error:&attachmentError]; if (attachmentError) { NSLog(@"%@", attachmentError.localizedDescription); } } completionHandler(attachment); }] resume];}- (void)serviceExtensionTimeWillExpire { // Called just before the extension will be terminated by the system. // Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used. self.contentHandler(self.bestAttemptContent);}@end

多媒体附件下载参考这篇文章

这里注意一下哈，前面在模拟器上下拉可以看到推送自定义的UI，我在iPhone5上怎么拉都不管用，后来才知道那是3D Touch，iPhone5还木有，所以一直看不到。
