用JSPatch 实现添加JSContext无效！
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
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...😢
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...
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 @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<NSCopying> *)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 ()<UIWebViewDelegate> @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<NSCopying> *)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。
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
