Ipad Can a'；UIButton'；在'中打开网页；UIWebView'；在同一个'；UIView'；？

我一直在为iPhone/iPad设备做这个项目，在完成项目的iPhone部分后，我突然想到改变iPad项目的风格

我的设想：

我有一个视图，其中包含链接到网站的UIButtons。最初我计划这些按钮使用一个按钮序列来打开单独的视图，其中已经有一个UIWebView来打开网页。但后来我想也许我可以使用UIButtons在父视图中打开所需的网页

我的问题:

是否可以使用UIButton加载网页，但在与用于加载网页的UIButton位于同一视图中的UIWebView中

提前感谢大家，我认为这应该是可能的，但目前还没有想到任何事情。

当然是可能的（真的……为什么不呢？）。您只有一个

UIView

，它有一个

UIWebView

和几个

UIButton

子视图。然后你可以这样做：

// Suppose that self.mainView is the main container (and an IBOutlet)
// and self.webView is the UIWebView (also an IBOutlet)
// and of course your UIButtons (connected to IBActions)

-(IBAction)visitSiteA:(id)sender
{
    NSString *urlAddress = @”http://www.siteA.com”;

    //Create a URL object.
    NSURL *url = [NSURL URLWithString:urlAddress];

    //URL Request Object
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

    //Load the request in the UIWebView.
    [self.webView loadRequest:requestObj];
}

-(IBAction)visitSiteB:(id)sender
{
    NSString *urlAddress = @”http://www.siteB.com”;

    //Create a URL object.
    NSURL *url = [NSURL URLWithString:urlAddress];

    //URL Request Object
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

    //Load the request in the UIWebView.
    [self.webView loadRequest:requestObj];
}

-(void)loadUrlAddress:(NSString *)urlAddress
{
    //Create a URL object.
    NSURL *url = [NSURL URLWithString:urlAddress]; 

    //URL Request Object
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

    //Load the request in the UIWebView.
    [self.webView loadRequest:requestObj];
}

-(IBAction)visitSiteA:(id)sender
{
    [self loadUrlAddress:@"http://www.siteA.com"];
}

现在，如果您不使用InterfaceBuilder，您可以在代码中构造webView和按钮，然后将它们添加到mainView中

最后，如果您计划有很多按钮，您可以通过将加载部分分解为一个单独的方法来优化代码，只需从IBActions传递url即可。大概是这样的：

// Suppose that self.mainView is the main container (and an IBOutlet)
// and self.webView is the UIWebView (also an IBOutlet)
// and of course your UIButtons (connected to IBActions)

-(IBAction)visitSiteA:(id)sender
{
    NSString *urlAddress = @”http://www.siteA.com”;

    //Create a URL object.
    NSURL *url = [NSURL URLWithString:urlAddress];

    //URL Request Object
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

    //Load the request in the UIWebView.
    [self.webView loadRequest:requestObj];
}

-(IBAction)visitSiteB:(id)sender
{
    NSString *urlAddress = @”http://www.siteB.com”;

    //Create a URL object.
    NSURL *url = [NSURL URLWithString:urlAddress];

    //URL Request Object
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

    //Load the request in the UIWebView.
    [self.webView loadRequest:requestObj];
}

-(void)loadUrlAddress:(NSString *)urlAddress
{
    //Create a URL object.
    NSURL *url = [NSURL URLWithString:urlAddress]; 

    //URL Request Object
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

    //Load the request in the UIWebView.
    [self.webView loadRequest:requestObj];
}

-(IBAction)visitSiteA:(id)sender
{
    [self loadUrlAddress:@"http://www.siteA.com"];
}

谢谢你，伙计，我知道我忽略了一些简单的事情
