除非我有缝.,否则我会遇到一个没有上载的客观上载荷舱的问题(没有上报/成功代表,服务器没有接到任何要求)。 它完美地运作。

I m new to objective-C, The setup is as follows: Main app instantiates a C++ class (cppClass) that runs a static function (cppFuncA) in a separate pThread.

法定职能(PppFuncA)即为客观的C类/目标(上载Func)提供一些数据并上载。

CppClass {
    static void cppFuncA (...);
} 

cppFuncA(...) {
    UploadFunc* uploader = [[[UploadFunc alloc] retain] init];
    while (condition) {
        ...
        [uploader uploadData:(NSData*)data];
    }
    [uploader release]
}

Uploader.h

@interface UploadFunc : NSObject
{
    bool conditional;
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error;
- (void)connectionDidFinishLoading:(NSURLConnection *)connection;
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response;
- (void) uploadData:(NSData*)data;
@end

Uploader.mm

@implementation UploadFeedback
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
    conditional = false;
    [connection release];
    NSLog(@"Connection failed! Error - %@ %@",
          [error localizedDescription],
          [[error userInfo] objectForKey:NSURLErrorFailingURLStringErrorKey]);
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    conditional = false;
    NSLog(@"Succeeded! Received %d bytes of data",0);
    [connection release];
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
    NSLog(@"Response=%@", response);
}

-(void) uploadData:(NSData*)data
{
    …
    NSMutableURLRequest *theRequest=[NSMutableURLRequest requestWithURL:theURL];
    … construct request …

    NSURLConnection* theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

    // Only works if I have this following spin loop
    conditional = true;
    while(conditional) {     
        [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]];
    }
    if (!theConnection) std::cerr << "Connection to feedback failed
";
}

最后一项职能“-(避免)上载数据:NSData*”是我提出问题的。 它不会在没有缝.的情况下工作。 有什么想法?

我补充说,保留了《民族权利倡议》和《民族权利倡议》,因此我认为,在请求没有被复制的情况下,它不是一个种族条件。

EDIT: I feel like these might be a similar issues: NSURLConnection - how to wait for completion and Asynchronous request to the server from background thread however my object (UploadFunc) still exists even after the function finishes and goes out of scope...
