获取推送通知的DeviceToken

在appDelegate实现文件里面。复写此方法：

保存到本地路径：#define DEST_PATH_DeviceToken [NSHomeDirectory() stringByAppendingString:@"/Library/Preferences/deviceToken.plist"]

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken

{

    //NSLog(@"My Token is %@",deviceToken);

  //转换成string

    NSString* dvsToken =[[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSetcharacterSetWithCharactersInString:@"<>"]];

    NSLog(@"My dvsToken is %@",dvsToken);

    //============保存dvsToken===========================

        NSMutableDictionary* dvsTokenDictionary = [NSMutableDictionary dictionary];

    [dvsTokenDictionary setObject:dvsToken forKey:@"dvsToken"]; //将dvsToken存入本地

    [dvsTokenDictionary writeToFile: DEST_PATH_DeviceToken atomically:YES];

}
