iphone - 如何让 UIBarButtonItem 向 UIWebView 发送新地址

Question

我在导航控制器中嵌入了一个 uiwebview。我希望能够通过简单地单击 uibarbuttonitem 来更改 uiwebview。有人知道该怎么做吗？

这是我现在的方法。

-(void)action {

    if (item.link) {
        self.linkString = item.link;
    }
    NSString *urlAddress = @"%@/#comments", linkString;

    NSURL *address = [NSURL URLWithString:urlAddress];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:address];
    [contentLabel loadRequest:requestObj];
}

Answer 1

您可以设置目标选择器或 IBAction 来更改请求对象：

  -(IBAction) action {
         NSString *urlAddress = @"http://google.com";

         NSURL *address = [NSURL URLWithString:urlAddress];
         NSURLRequest *requestObj = [NSURLRequest requestWithURL:address];
         [theWebView loadRequest:requestObj];
    }

或者

  -(void) action {
         NSString *urlAddress = @"http://google.com";

         NSURL *address = [NSURL URLWithString:urlAddress];
         NSURLRequest *requestObj = [NSURLRequest requestWithURL:address];
         [theWebView loadRequest:requestObj];
    }
