因此,這裏是我的問題:NSURL連接會/不會加載數據
我跟着iPhone開發者文檔幾乎到T的NSURLConnection tutorial,它只是有點工作。
這裏就是這一切都錯了:
對象似乎是正確的,並委託給connectionDidFinishLoading創建的,但任何URL我嘗試加載的響應數據最終總是隻爲0字節。如果這有什麼不同,我正在模擬器中運行。
這裏是我的相關代碼:
- (void)viewDidLoad {
[super viewDidLoad];
self.title = @"WVFS Player";
//create a request
NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://wvfs.josh-kaplan.com/nowPlaying.php"]
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
// create a connection
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if(theConnection) {
// create the datum
responseData=[[NSMutableData data] retain];
} else {
// code this later
}
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[responseData setLength:0];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
// make it work
NSLog(@"Succeeded! Received %d bytes of data:",[responseData length]);
// release it
[connection release];
[responseData release];
}
這是我的日誌輸出:

任何想法?
