项目中使用的是WKWebView,以下是从项目中抽取出来的，供想使用WKWebView的朋友们了解。

　　可以直接修改代码中的的控制器类名和类中的方法名，可更快速的拿到项目中使用。

(a) .h定义文件

　　

#import 
     
      @interface HZWebViewController : UIViewController@end
     

　

(b) .m实现文件

 

#import "HZWebViewController.h"#import 
     
      @interface HZWebViewController ()
      
       @property (nonatomic,strong) WKWebView *webView;@end@implementation HZWebViewController- (void)viewDidLoad {    [super viewDidLoad];    // Do any additional setup after loading the view.        // 基本配置    [self commonInit];

         // 字典数组->Json,与H5之间是通过Json数据格式进行交互     NSString *str = [dictArray toJSONString];          // backOrderWeb 是H5定义好的方法     NSString *js = [NSString stringWithFormat:@"backOrderWeb(%@)",str];     */        // js代码中可以传包含多个模型的数组等等    NSString *js = @"";
