webview load html by jspatch has issue

[bang590]

What did you mean?

[yuzhoulangzik]

loadweb : function() { var webView = UIWebView.alloc().initWithFrame(self.view().frame()) webView.setDelegate(self) var url = NSURL.URLWithString("https://www.baidu.com/") var request = NSURLRequest.alloc().initWithURL(url) self.view().addSubview(webView) webView.loadRequest(request) }

missed require()

var webView = require('UIWebView').alloc().initWithFrame(self.view().frame())

[yuzhoulangzik]

@albert438 had add require('UIWebView'),

@yuzhoulangzik Confirmed. I guess it's a conflict between JSPatch and UIWebvView, for both of them use JSCore.framework. It seems that it's unable to init UIWebView in JSPatch. I start the UIWebview in appdelegate and it worked.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    UIWebView *view = [[UIWebView alloc]init];   //Useless. Just to load the UIWebview framework.
    view.frame = CGRectZero;

    [JPEngine startEngine];
   //.......

    return YES;
}

[yuzhoulangzik]

@albert438 //defineClass('UIWebView',{

// loadRequest :function(request){ // self.valueForKeyPath("documentView.webView.mainFrame.javaScriptContext") // self.ORIGloadRequest(request) // } // })

overwrite loadRequest it work

[huohuoluo]

in our app, I write [JPEngine startEngine] in

• (BOOL)application:(UIApplication )application didFinishLaunchingWithOptions:(NSDictionary )launchOptions { }

and all the viewcontroller that contains a webview will crash.

I think [JSPatch startEngine] should be called after webview calss something init (lazy load).

Now we can use -performSelectorInOC API to avoid the conflict of JavaScriptCore and UIWebView:

loadweb : function() {
    return UIWebView.performSelectorInOC('new', [], function(ret) {
        var webview = ret;
        webView.setDelegate(self)
        var url = NSURL.URLWithString("https://www.baidu.com/")
        var request = NSURLRequest.alloc().initWithURL(url)
        self.view().addSubview(webView)
        webView.loadRequest(request)
    })
}

@albert438 this can be work for me ,but send a new version to appstore

@bang590 问下邦神，在需要覆盖的方法里没有直接调用uiwebview，但是某些代码会唤起带webview的viewcontroller，这种情况应该对需要覆盖的整个方法执行performSelectorInOC 吗？

[lynulzy]

上段代码

defineClass("AppDelegate", {
    application_openURL_sourceApplication_annotation: function(application, url, sourceApplication, annotation) {

            if (url.absoluteString().isEqualToString("***://")) {
            return 1
        }
        // self.ORIGapplication_openURL_sourceApplication_annotation(application, url, sourceApplication, annotation);
    }
})

其中注释掉的那句，能否使用PerformSelectorInOC呢？

[xmw-simon]

大神，UIWebView.performSelectorInOC这个api在初始化UIWebView之后,WebView里面的点击事件全部失效了!!
