Question

使用 NSConnonction 连接到 www.google.com 时出错。

我找不到原因任何帮助都会感激不尽

NSString *urkString = @"www.google.com";
NSURL *url = [NSURL URLWithString:urkString];

NSURLRequest *request = [NSURLRequest requestWithURL:url
                                          cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval:60];

_connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];  
if(_connection)
{
    _receivedData = [[NSMutableData alloc] init];
}
else
{
    UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"Error" message:@"Cannot connect to the Web site." delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil];

    [alertView show];
    [alertView release];
}

但它称为这个方法。错误是:

Error Domain=NSURLErrorDomain 代码=-1002 “不支持的 URL” UseInfo= 0x4c9feb0 {NSError FailingURLStringKey=www.google.com, NSerror FailingURLKey=www.google.com, NNS 本地化Description=不支持的 URL, NS suidelineError= 0x4c9ff0 “不支持的 URLStringKey”\/code



- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
    _endSystemDate = [self getSystemDate];
    _receivedData = nil;
    _connection = nil;
    _status = @"Completed";
}

Answer 1

尝试 NSString *urkString = @ "http://www.google.com" ; 您需要在每个 URL 方案中设置 URL 方案。即 http:// /code > 或 https://
