我测试过无数次，用用JSPatch 实现Objective-C原生的JSContext无效！

并且，WebView已经正常初始化了，不存在任何问题。self.context()也能console.log()出内存地址！

我写的代码如下：

defineClass('ActionViewController', {
    webViewDidFinishLoad: function(webView) {

        self.ORIGwebViewDidFinishLoad(webView);

        var weakSelf = __weak(self);

        self.context().setObject_forKeyedSubscript(block(function() {
            dispatch_async_main(function(){
                var vc = SPOfferHomeViewController.viewController();
                weakSelf.navigationController().pushViewController_animated(vc, 1);
            });
        }), "openCustomOffer");

        self.context().setObject_forKeyedSubscript(block(function() {
            dispatch_async_main(function(){
                var vc = SPMarketCenterViewController.viewController();
                weakSelf.navigationController().pushViewController_animated(vc, 1);
            });
        }), "openMarketCenter");

    }
});

试试用这个 https://github.com/bang590/JSPatch/wiki/performSelectorInOC-%E4%BD%BF%E7%94%A8%E6%96%87%E6%A1%A3

听了您的意见，我改成了这样：

defineClass('ActionViewController', {
    webViewDidFinishLoad: function(webView) {

        self.ORIGwebViewDidFinishLoad(webView);

        var weakSelf = __weak(self);

        var b1 = block(function() {
            dispatch_async_main(function(){
                var vc = SPOfferHomeViewController.viewController();
                weakSelf.navigationController().pushViewController_animated(vc, 1);
            });
        });

        return self.context().performSelectorInOC('setObject:forKeyedSubscript:', [b1, "openCustomOffer"], function() {

            var b2 = block(function() {
                dispatch_async_main(function(){
                    var vc = SPMarketCenterViewController.viewController();
                    weakSelf.navigationController().pushViewController_animated(vc, 1);
                });
            });

            return weakSelf.context().performSelectorInOC('setObject:forKeyedSubscript:', [b2, "openMarketCenter"], function() {});

        });
    }
});

但是非常遗憾的是，还是不行？请指教

bang590 commented 8 years ago

试试self.context()也改成用performSelectorInOC，里面那个也是

Nihility-Ming commented 8 years ago

defineClass('ActionViewController', {
    webViewDidFinishLoad: function(webView) {

        self.ORIGwebViewDidFinishLoad(webView);

        var weakSelf = __weak(self);

        return self.performSelectorInOC('context', [], function(con) {
            var b1 = block(function() {
                dispatch_async_main(function(){
                    var vc = SPOfferHomeViewController.viewController();
                    weakSelf.navigationController().pushViewController_animated(vc, 1);
                });
            });

            return con.performSelectorInOC('setObject:forKeyedSubscript:', [b1, "openCustomOffer"], function() {

                var b2 = block(function() {
                    dispatch_async_main(function(){
                        var vc = SPMarketCenterViewController.viewController();
                        weakSelf.navigationController().pushViewController_animated(vc, 1);
                    });
                });

                return con.performSelectorInOC('setObject:forKeyedSubscript:', [b2, "openMarketCenter"], function() {});

            });

        });

    }
});

也是不行噢...😢

bang590 commented 8 years ago

哪一步开始不行呢？调试下

Nihility-Ming commented 8 years ago

用WEB检查器调试过，没有任何语法异常，主要就是不走Block里面的内容，也就是设置JSContext （setObject:forKeyedSubscript:）无效...

bang590 commented 8 years ago

setObject:forKeyedSubscript:传非block有效吗

Nihility-Ming commented 8 years ago

传非Block？总之就是无法响应那个Object了，我试着传递一个字符串对象，还是没有根据Key来响应Object。

以下的代码OC正常，我翻译成JSPatch语法则不行...

    __weak __typeof(self) weakSelf = self;
    [self.context setObject:^{
        dispatch_async(dispatch_get_main_queue(), ^{
            SPOfferHomeViewController *vc = [SPOfferHomeViewController viewController];
            [weakSelf.navigationController pushViewController:vc animated:YES];
        });
    } forKeyedSubscript:@"openCustomOffer"];

    [self.context setObject:^{
        dispatch_async(dispatch_get_main_queue(), ^{
            SPMarketCenterViewController *vc = [SPMarketCenterViewController viewController];
            [weakSelf.navigationController pushViewController:vc animated:YES];
        });
    } forKeyedSubscript:@"openMarketCenter"];

Nihility-Ming commented 8 years ago

大神可以试着写一个简单的Demo噢，可能这个问题还能写入WIKI呢...

action121 commented 8 years ago

@Nihility-Ming @bang590 看了你们的讨论，我试着做了一下，发现这样可以实现。

===oc代码====

import <JSPatch/JPEngine.h>

typedef void(^JSBridgeBlock)(id p0,id p1,id p2,id p3,id p4,id p5,id p6,id p7,id p8,id p9);

@interface MYJSContext :JSContext

@end @implementation MYJSContext

-(void)setObject:(id)object forKeyedSubscript:(NSObject *)key{

JSBridgeBlock evalFunc = object;

JSBridgeBlock callBack = ^(id p0,id p1,id p2,id p3,id p4,id p5,id p6,id p7,id p8,id p9){

    evalFunc(p0,p1,p2,p3,p4,p5,p6,p7,p8,p9);

};
[super setObject:callBack forKeyedSubscript:key];

}

@end

@interface ViewController () @property (strong, nonatomic) UIWebView webview; @property (strong, nonatomic) MYJSContext context; @end

@implementation ViewController

(void)viewDidLoad { [super viewDidLoad];

self.context = [[MYJSContext alloc] init]; self.context.exceptionHandler = ^(JSContext con, JSValue exception) { NSLog(@"%@", exception);

}; } -(UIWebView*)webview{ if (!_webview) { _webview = [[UIWebView alloc] initWithFrame:self.view.bounds]; _webview.delegate = self; [self.view addSubview:_webview];

} return _webview; } -(void)viewDidAppear:(BOOL)animated{ [super viewDidAppear:animated];

NSURL* url = [NSURL URLWithString:@"http://www.baidu.com"]; [self.webview loadRequest:[NSURLRequest requestWithURL:url]]; }

-(void)webViewDidFinishLoad:(UIWebView )webView{ JSValue value = [self.context objectForKeyedSubscript:@"fromjspatch"]; if (value) { [value callWithArguments:@[@[@1,@2,@3],@"3",@"2"]]; } }

@end

====js代码==

defineClass('ViewController', {

        viewDidLoad:function(){

            self.ORIGviewDidLoad();

            var b1 = block("NSArray*,NSString*,NSString*",function(a,b,c) {
                                console.log("from jspatch count:    " + a.count() + "   b: "  + b.toJS() + "    c: " + c.toJS());

                           });

            return self.performSelectorInOC('context', [], function(context) {

                        return context.performSelectorInOC('setObject:forKeyedSubscript:', [b1, "fromjspatch"], function() {});

            });

        }

})

但我不清楚为什么在-(void)setObject:(id)object forKeyedSubscript:(NSObject *)key这个方法里用block重新包一下就正常了，你们如果知道还请解释一下。

billxie1988 commented 8 years ago

我也遇到了类似的问题在JSContext 里面设置的block 没有回调.不过我发现是这个 [context setObject:@"" forKeyedSubscript:^() {}];没有起到效果

hellovoidworld commented 7 years ago

这个问题解决了吗？我也遇到了这个问题，除了@action121 要增加一个包装类的方法
