发送设备令牌服务器

Question

我读了很多的教程，这和我只是想TI知道这是做这个

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken 
{ 
    NSLog(@"My token is: %@", deviceToken); 

    NSString* newToken = [deviceToken description]; 

    newToken = [newToken stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]]; 
    newToken = [newToken stringByReplacingOccurrencesOfString:@" " withString:@""]; 


    NSString *urlString = [NSString stringWithFormat:@"http://myhost.com./filecreate.php?token=%@",newToken]; 

    NSURL *url = [[NSURL alloc] initWithString:urlString]; 

    NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url]; 

    NSData *urlData; 
    NSURLResponse *response; 
    urlData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:nil]; 

} 

任何建议更然后欢迎正道。

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

    const char* data = [deviceToken bytes]; 
    NSMutableString* token = [NSMutableString string]; 

    for (int i = 0; i < [deviceToken length]; i++) { 
     [token appendFormat:@"%02.2hhX", data[i]]; 
    } 


    NSString *urlString = [NSString stringWithFormat:@"http://myhost.com/filecreate.php?token=%@",token]; 

    NSURL *url = [[NSURL alloc] initWithString:urlString]; 

    NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url]; 
    NSData *urlData; 
    NSURLResponse *response; 
    urlData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:nil]; 

} 

我的应用程序适用于两种代码，但什么是正确的方法？

由于MJA在评论中说，这是更好地添加错误恢复机制（如果请求失败，你会失去你的令牌），并使用异步请求（在后台发送令牌）

在你AppDelegate.m：

​​

要发送的令牌创建新类（或者利用现有的一个）：
DataUpdater.h

#import <Foundation/Foundation.h> 

@interface DataUpdater : NSObject  
+ (void)sendUserToken; 
@end 

DataUpdater.m

#import "DataUpdater.h" 

@implementation DataUpdater 

+ (void)sendUserToken { 
    if ([[NSUserDefaults standardUserDefaults] boolForKey:@"apnsTokenSentSuccessfully"]) { 
     NSLog(@"apnsTokenSentSuccessfully already"); 
     return; 
    } 

    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://myhost.com/filecreate.php?token=%@",[[NSUserDefaults standardUserDefaults] objectForKey:@"apnsToken"]]]; //set here your URL 

    NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url]; 
    NSOperationQueue *queue = [[NSOperationQueue alloc] init]; 

    [NSURLConnection sendAsynchronousRequest:urlRequest queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) 
    { 
     if (error == nil) { 
      [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"apnsTokenSentSuccessfully"]; 
      NSLog(@"Token is being sent successfully"); 
      //you can check server response here if you need 
     } 
    }]; 
} 

@end 

然后就可以调用[DataUpdater sendUserToken]当Internet连接出现在控制器，或定期或在- （无效）viewDidLoad中或- （无效）viewWillAppear中方法

我的建议：
1）我用AFNetworking发送异步请求，并检查服务器JSON响应
2）有些时候，它更好地使用服务，如Parse与推送通知工作

在didFinishLaunchingWithOptions方法

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

上面的代码行后做，下面添加

#pragma mark - 
#pragma mark Push Notifications 
- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken 
{ 
NSString *token_string = [[[[deviceToken description] stringByReplacingOccurrencesOfString:@"<"withString:@""] 
          stringByReplacingOccurrencesOfString:@">" withString:@""] 
          stringByReplacingOccurrencesOfString: @" " withString: @""]; 
NSString* strURL = [NSString stringWithFormat:@"http://www.sample.com?device_token=%@&type=IOS",token_string]; 
strURL=[strURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 
NSLog(@"%@",strURL); 
NSData *fileData = [NSData dataWithContentsOfURL:[NSURL URLWithString:strURL]]; 
NSLog(@"content---%@", fileData); 
}
