iphone - 使用按钮停止 UiWebView

Question

现在我的项目自动重新加载（在此站点上的某人的帮助下：D）我怎么能得到另一个但停止重新加载？这就是我所拥有的：

-(IBAction)SendGPSData:(id)sender {
    NSURL *myURL =[NSURL URLWithString:@"http://www.google.co.uk"];//<<change this!!!
    NSURLRequest *myRequest = [NSURLRequest requestWithURL:myURL];
    [myWebView2 loadRequest:myRequest];
        [myWebView2 reload];
    [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(WebViewLoad:) userInfo:nil repeats:YES];

}

-(IBAction)stop:(id)sender {

//what do i put here to stop it reloading?

}

-(void)WebViewLoad:(NSTimer *)theTimer
{
    [myWebView2 reload];

} 

不喜欢这么快问另一个问题，但我是 Xcode 的初学者，所以任何帮助都会很棒:)

Iv 尝试了 myWebView 停止加载；但原来的似乎覆盖了这个:(

Answer 1

你可以这样停止：

-(IBAction)stop:(id)sender {

[webView stopLoading];

}

Answer 2

您还需要停止计时器。所以你也是：

NSTimer* reloadTimer;  // Put this in your class.

reloadTimer = [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(WebViewLoad:) userInfo:nil repeats:YES];


-(IBAction)stop:(id)sender
{
    [reloadTimer invalidate];
    reloadTimer = nil;   // Prevents crash, when this method is called twice:
                         // reloadTimer is released when you call invalidate,
                         // so next time invalidate would be called on non-existing
                         // object -> crash.

    [myWebView2 stopLoading];
}

将启动/创建计时器的代码放在单独的方法中可能是有意义的，这样您就可以使用它重新启动重新加载。
