JavaScriptTalkNativeEasy 是一个iOS平台用于Obj-C和JavaScript交互的库,此库是基于 Apple 的JavaScriptCore 、 WebKit 、 runtime进行封装的。


通过pod进行安装
pod 'JavaScriptTalkNativeEasy'
在UIWebView中使用

JavaScript 中对应相关的代码。


<script>
function test() {
var userInfo = getUserInfo('Hello Native!!!');
document.write('Name:'+userInfo.name);
document.write('<br>');
document.write('Age:'+userInfo.age);
}
</script>
#import <UIKit/UIKit.h>
#import "JavaScriptTalkNativeEasyProtocol.h"
@protocol WebJSEasyProtocol<JavaScriptTalkNativeEasyProtocol>
-(NSDictionary *)getUserInfo:(NSString *)string;//和javaScript中对应的函数名一致。
@end
@interface JSTNEUIWebViewController : UIViewController
@end
// WebJSEasyProtocol 协议必须继承JavaScriptTalkNativeEasyProtocol,此协议名称可以替换成您自己想要的,协议中的方法名必须和JavaScript端对应的�要掉的函数名称一致。
@interface JSTNEUIWebViewController ()<UIWebViewDelegate,WebJSEasyProtocol>
{
UIWebView *webView;
}
@property(nonatomic, strong)JavaScriptTalkNativeEasy *jsTNEasy;
@end
@implementation JSTNEUIWebViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.title = @"UIWebView";
webView = [[UIWebView alloc] initWithFrame:[UIScreen mainScreen].bounds];
[self.view addSubview:webView];
_jsTNEasy = [JavaScriptTalkNativeEasy jsTNEasy:webView];
_jsTNEasy.delegate = self;
NSString* htmlPath = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"];
NSString* exampleHtml = [NSString stringWithContentsOfFile:htmlPath encoding:NSUTF8StringEncoding error:nil];
NSURL *baseURL = [NSURL fileURLWithPath:htmlPath];
[webView loadHTMLString:exampleHtml baseURL:baseURL];
webView.delegate = self;
}
-(NSDictionary *)getUserInfo:(NSString *)string{
NSLog(@"%@",string);
return @{@"name":@"Univex",@"age":@27};
}
@end
在WKWebView中使用

JavaScript 中对应相关的代码。


<script>
function test() {
window.webkit.messageHandlers.getUserInfo.postMessage({'message':'Hello Native!!!','callBackFromNative':'userInfo'});
}
function userInfo(user){
document.write(user.name)
document.write('<br>')
document.write(user.age)}
</script>
@protocol WKWebJSEasyProtocol<JavaScriptTalkNativeEasyProtocol>
-(NSDictionary *)getUserInfo:(NSDictionary *)dic; //和javaScript中对应的函数名一致。
@end
@interface JSTNEWKWebViewController : UIViewController
@end
// WKWebJSEasyProtocol 协议必须继承JavaScriptTalkNativeEasyProtocol,此协议名称可以替换成您自己想要的,协议中的方法名必须和JavaScript端对应的�要掉的函数名称一致。
@interface JSTNEWKWebViewController ()<WKScriptMessageHandler,WKNavigationDelegate,WKUIDelegate,WKWebJSEasyProtocol>
@property(nonatomic, strong)WKWebView *webView;
@property(nonatomic, strong)JavaScriptTalkWKNativeEasy *jsTNEasy;
@end
@implementation JSTNEWKWebViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.title = @"WKWebView";
WKWebViewConfiguration *configuration = [[WKWebViewConfiguration alloc] init];
_webView = [[WKWebView alloc] initWithFrame:self.view.bounds configuration:configuration];
[self.view addSubview:_webView];
configuration.preferences.javaScriptEnabled = YES;
configuration.preferences.javaScriptCanOpenWindowsAutomatically = NO;
NSString* htmlPath = [[NSBundle mainBundle] pathForResource:@"index_wk" ofType:@"html"];
NSString* exampleHtml = [NSString stringWithContentsOfFile:htmlPath encoding:NSUTF8StringEncoding error:nil];
NSURL *baseURL = [NSURL fileURLWithPath:htmlPath];
[_webView loadHTMLString:exampleHtml baseURL:baseURL];
_webView.navigationDelegate = self;
_webView.UIDelegate = self;
_jsTNEasy = [JavaScriptTalkWKNativeEasy jsTNEasy:_webView];
_jsTNEasy.delegate = self;
}
-(NSDictionary *)getUserInfo:(NSDictionary *)dic{
NSLog(@"%@",dic);
return @{@"name":@"Univex",@"age":@27};
}
@end
