ios - 使用 Xcode 在 iOS 应用程序中调用网页

Question

我如何在 iOS 应用程序中调用网页(访问它而不在显示器上显示)？ 我希望能够拥有一个 iOS 应用程序，当打开时，将在后台加载一个网页，这将执行一个 shell 脚本。

我认为您应该将 NSURLConnection 与您的 URL 一起使用，并忽略收到的数据。查看 Apple 文档:

// Create the request.
NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.apple.com/"]
                    cachePolicy:NSURLRequestUseProtocolCachePolicy
                timeoutInterval:60.0];

// Create the NSMutableData to hold the received data.
// receivedData is an instance variable declared elsewhere.
receivedData = [NSMutableData dataWithCapacity: 0];

// create the connection with the request
// and start loading the data
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if (!theConnection) {
    // Release the receivedData object.
    receivedData = nil;

    // Inform the user that the connection failed.
}
