Question

我正在尝试拨打网络服务，但不幸的是我的电话没有录制，我不确定为什么会这样做......

这是我正在使用的代码，也许我错过了一些东西：

NSURL *URL = [NSURL URLWithString:@"http://www.google.com"];
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:URL];

NSURLResponse *response = nil;
NSError *error = nil;
NSData *data = [NSURLConnection sendSynchronousRequest:req returningResponse:&response error:&error];

我需要做的就是能够加载网页，而不必在safari或web视图中加载它

谢谢！

NSURL *url = [NSURL URLWithString:webService];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:60.0];
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];    
    if(theConnection) {
        //webData = [[NSMutableData data] retain];      
    }else {
        NSLog(@"The Connection is NULL");
    }
}

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
    webData = [[NSMutableData data] retain];
}

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

-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
}
