objective-c - 在 UIWebView 完全加载后执行操作

Question

当 WebView 完全加载页面时，我有什么方法可以运行一些代码？如果有帮助，这是我用来在视图中打开网页的代码。

//Load URL Into WebView
NSString *urlAddress = @"http://example.com";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[[_listenupwebkit mainFrame] loadRequest:requestObj];

我的.m文件

- (IBAction)SignInButton:(id)sender {
//Load URL Into WebView

NSString *urlAddress = @"http://www.pandora.com/account/sign-in";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[_listenupwebkit setFrameLoadDelegate:delegate];
[[_listenupwebkit mainFrame] loadRequest:requestObj];


loginbutton.hidden = YES;
webkithome.enabled = YES;



}

和

- (void)webView:(WebView *)sender didFinishLoadForFrame:(WebFrame*)frame
{
    if(frame == [sender mainFrame]) {
        NSLog(@"viewDidLoad");
    }
}

我的.h文件

- (void)webView:(WebView *)sender didFinishLoadForFrame:(WebFrame*)frame;
@end

提供一个实现

- (void)webView:(WebView *)sender didFinishLoadForFrame:(WebFrame*)frame

在你的frameLoadDelegate.

[_listenupwebkit setFrameLoadDelegate:delegate];
[[_listenupwebkit mainFrame] loadRequest:requestObj];

在方法实现中，查看完成的帧是否是主帧：

 - (void)webView:(WebView *)sender didFinishLoadForFrame:(WebFrame*)frame
 {
    if(frame == [sender mainFrame]) {
