iphone - 将 NSString 传递给 Webview

Question

我有一个NSString被调用的状态，我正在尝试将该变量传递给加载一个webView. 该应用程序在这里崩溃，但我不知道我做错了什么？有人看到请求有什么问题吗？

[webView loadRequest:[NSURLRequest requestWithURL:[NSString 
stringWithFormat:@"http://www.website.com/page.php?status=%@", status]]];

Answer 1

requestWithURL接受NSURL，所以你需要将字符串转换成NSURL

试试这个，

[webview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://www.website.com/page.php?status=%@", status]]]];

Answer 2

NSString *urlAddress = [NSString stringWithFormat:@"http://www.website.com/page.php?status=%@", status];
//Create a URL object.
NSURL *url = [NSURL URLWithString:urlAddress];
//URL Requst Object
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
//Load the request in the UIWebView.
[webView loadRequest:requestObj];

Answer 3

+[NSURLRequest requestWithURL:]期待你给它一个NSURL对象。你给它一个NSString. 不要那样做。:)

Answer 4

用这个：

[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString  stringWithFormat:@"http://www.website.com/page.php?status=%@", status]]]];
