我使用 Yelp 搜索 API 基本上只是获取用于搜索查询的企业列表。

NSURLConnection 几乎就是 OAuth，但这里是初始化请求的代码：

 NSURL *URL = [NSURL URLWithString:appDelegate.yelpAdvancedURLString];


OAConsumer *consumer = [[OAConsumer alloc] initWithKey:@"this-is-my-key" secret:@"this-is-my-secret"];
OAToken *token = [[OAToken alloc] initWithKey:@"this-is-my-key" secret:@"this-is-my-secret"];

id<OASignatureProviding, NSObject> provider = [[OAHMAC_SHA1SignatureProvider alloc] init];
NSString *realm = nil;

OAMutableURLRequest *request = [[OAMutableURLRequest alloc] initWithURL:URL

                                                               consumer:consumer
                                                                  token:token
                                                                  realm:realm
                                                      signatureProvider:provider];

[request prepare];

responseData = [[NSMutableData alloc] init];


yelpConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

那么这里：

  - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {

    [responseData setLength:0];
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
    [responseData appendData:data];

}

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
    NSLog(@"Error: %@, %@", [error localizedDescription], [error localizedFailureReason]);

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle: @"Oops." message: @"Something screwed up. Please search again." delegate: nil cancelButtonTitle:@"OK" otherButtonTitles:nil];

                [alert show];

     [MBProgressHUD hideHUDForView:self.view animated:YES];
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{       
    if (connection == self.yelpConnection) {
        [self setYelpString];

    }
}

当我在 iPhone 上运行它时，一切正常。但是，当我在 iPad 上运行时，连接会超时。以下来自这一行

 NSLog(@"Error: %@, %@", [error localizedDescription], [error localizedFailureReason]);

 Error: The request timed out., (null)

另外，如果我使用同步请求，它似乎可以使用：

 NSData* result = [NSURLConnection sendSynchronousRequest:request  returningResponse:&response error:&error];

NSDictionary* JSON = [NSJSONSerialization
                      JSONObjectWithData:result
                      options:kNilOptions
                      error:&error];

但是，我想避免使用同步，因为它会冻结应用程序。

这个 Yelp API 是特定的吗？还是我只是做错了什么？在此先感谢，我将不胜感激。

如果有帮助，它会在发送请求后大约 10 秒超时。

创建这种类型的 NSMutableURLRequest ：

NSMutableURLRequest* request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:url] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:240.0];

我认为最好的方法是将http://oauth.googlecode.com中的 init 方法从

- (id)initWithURL:(NSURL *)aUrl
         consumer:(OAConsumer *)aConsumer
            token:(OAToken *)aToken
            realm:(NSString *)aRealm
signatureProvider:(id<OASignatureProviding, NSObject>)aProvider
{
     if (self = [super initWithURL:aUrl
                       cachePolicy:NSURLRequestReloadIgnoringCacheData
               timeoutInterval:10.0])
{    
       ...
    }

}

至

- (id)initWithURL:(NSURL *)aUrl 
      cachePolicy:(NSURLRequestCachePolicy)cachePolicy 
  timeoutInterval:(NSTimeInterval)timeoutInterval
         consumer:(OAConsumer *)aConsumer
            token:(OAToken *)aToken
            realm:(NSString *)aRealm
 signatureProvider:(id<OASignatureProviding, NSObject>)aProvider
 {
     if (self = [super initWithURL:aUrl
                       cachePolicy:cachePolicy
               timeoutInterval:timeoutInterval])
{    
       ...
    }

然后再次检查您指定的超时值是否会被连接接受。
