oc 与 JavaScript 交互存在内存泄漏问题

[雾里寻梦]

@property (nonatomic,weak) JSContext *jsContext;


-(void)webViewDidFinishLoad:(UIWebView *)webView{
    __weak typeof(self) weakSelf = self;
    self.jsContext[@"DsJsBridge"] = weakSelf;
    self.jsContext.exceptionHandler = ^(JSContext *context, JSValue *exceptionValue) {
        context.exception = exceptionValue;
        NSLog(@"异常信息：%@", exceptionValue);
    };
}

所加载网页里面嵌入了iframe，导致webViewDidFinishLoad多次回调，这样 self.jsContext[@"DsJsBridge"] = weakSelf;也会被执行多次，这样导致self无法释放，大家有遇到这个问题么？

[不担心]

__weak typeof(self.context) wcnt = self.context; block中用 wcnt.exception = exceptionValue;
