JS与OC交互--简单使用（打电话）

.m文件

#import "ViewController.h"

@interface ViewController ()<UIWebViewDelegate>
@property (weak, nonatomic) IBOutlet UIWebView *webView;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

- (void)call{
    
    
    //拨打电话
    [[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"tel://10086"]];
}

//是否允许加载从webview获得的请求
/*
 *该方法可以实现js调用OC
 *js和OC交互的第三框架可以使用：WebViewJavaScriptBridge
 */

    //获得html点击的链接
    NSString *url = request.URL.absoluteString;
    //设置协议头
    NSString *scheme = @"zc://";
    //判断获得的链接前面是否包含设置头
