iOS objective-c如何在UIWebView中捕获window.open事件

@interface YourViewController : UIViewController <UIWebViewDelegate>
@property (nonatomic, strong) UIWebView *webView;
@end

@implementation YourViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    self.webView = [[UIWebView alloc] initWithFrame:self.view.bounds];
    self.webView.delegate = self;
    [self.view addSubview:self.webView];
    
    // 加载网页
    NSURL *url = [NSURL URLWithString:@"https://example.com"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [self.webView loadRequest:request];
}

// ...

@end

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
    NSString *urlString = request.URL.absoluteString;
    
    // 判断是否为window.open事件
    if ([urlString hasPrefix:@"window.open"]) {
        // 处理window.open事件
        // ...
        
        // 返回NO，阻止UIWebView加载该请求
        return NO;
    }
    
    // 其他情况正常加载请求
    return YES;
}
