如何在iphone中傳遞'Accept-Language'標頭？

Question

如何在iphone中的http請求中傳遞'Accept-Language'標頭？ 在我的http請求中，標題爲空。這是附加在框架級別嗎？ 如果是這樣，有沒有辦法攔截它並進行修改？

+(NSMutableURLRequest*)assembleHTTPRequestHead:(NSMutableURLRequest *) requester 
{ 
    // These are the headers we need, we get ride of everything else 
    NSArray *headers = [NSArray arrayWithObjects:@"User-Agent", nil]; 
    NSString* appName = [self getAppName]; 
    NSArray *values = [NSArray arrayWithObjects: appName, nil]; 

    // Add our headers 
    for (NSString *header in headers) { 
     // We use setValue to overwrite any value in an existing 
     // header, addValue appends to the values. 
     id theValue =[values objectAtIndex:[headers indexOfObject:header]]; 
     [requester setValue:theValue forHTTPHeaderField:header ]; 

     AppTrace3(self, @"Added Header", header, theValue); 
    } 
    AppTrace2(self, @"assembleHTTPRequestHead done", requester); 

    return requester; 
}
