我有一个带有一行按钮的水平滚动视图.滚动视图不会滚动,除非我进行非常快速的滑动.
如果我将按钮设置为userInteractionEnabled = NO,则滚动按预期工作,但当然按钮根本不起作用.
此应用程序在iOS 7及之前运行良好.它似乎是一个iOS 8"功能".我注意到我可以捕获按钮的拖动事件,但我不知道如何将其重定向回scrollView.
我想我需要用UIViews替换我的按钮并自己管理这些事件,但如果有人有其他想法或解决方案,我将不胜感激.
由于一些性能问题,我正在尝试升级angularJS2/phonegap应用程序以在iOS上使用WKWebView.
不幸的是,任何对路线导航的调用都不起作用.这包括routerlink和this.route.navigate电话.没有错误被抛出.有没有其他人看过这个和/或可能有一个解决方法？
使用普通的UIWebView,代码工作正常.
我是Angular的新手,所以欢迎任何建议.
以下是一些相关代码的样子:
import { Component } from "@angular/core";
import { Routes, Router, ActivatedRoute } from "@angular/router";
import { LoggedInCallback } from "./service/cognito.service";
export class HomeComponent implements LoggedInCallback {
constructor(public router:Router){
}
isLoggedIn(message:string, isLoggedIn:boolean) {
if (isLoggedIn){
this.router.navigate(['/home/cl']);
}
else {
console.log('HomeComponent: '+message);
}
}
路由模块:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { Routes, RouterModule } from '@angular/router';
import { CategoryListComponent …我最近更新到了React Native@0.60.4.
该应用程序在 iOS 和 xcode 上编译并运行良好。但是，当我尝试运行新的 android 代码时，我遇到以下错误：
/redacted/MainApplication.java:6: error: cannot find symbol
import com.facebook.react.PackageList;
^
symbol: class PackageList
location: package com.facebook.react
/redacted/MainApplication.java:28: error: cannot find symbol
List<ReactPackage> packages = new PackageList(this).getPackages();
^
symbol: class PackageList

* What went wrong:
Execution failed for task ':app:compileDebugJavaWithJavac'.
> Compilation failed; see the compiler error output for details.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info …给定一个这样的输入字符串:
"blah <b>abc <i>foo</i> GETME bar </b> GETME <b>something else</b>"
我想写一个PERL正则表达式,产生一个结果字符串,如:
"blah <b>abc <i>foo</i> bar </b> GETME <b>something else</b>
其中的"GETME" <b>,并</b>已被删除.基本上我想删除开始<b>和结束</b>标记之间的所有"GETME"实例.
我已经看到有一个"平衡"包来处理这个问题,但它似乎有点矫枉过正.有更简单的解决方案吗？
就像是:
$teststr =~ s/(<b>[^>]*?)GETME(.*?<\/b>)/$1$2/g;
但是只有在没有嵌套标签的情况下才有效,但是<i>在<b>和之间</b>.
理想情况下我可以这样写:
$teststr =~ s/<b>(.*?)</b>/{$1 =~ s/GETME//g}/g;
我嵌套另一个正则表达式,但如果这样的话可能,我不知道语法.
我试图将我的 react-native 版本更新为最新版本。即 react-native 0.60.3 这两种方法出现以下错误。

我是一个围棋新手。我正在尝试在 MacOS BigSur 上安装 gomobile 进行评估，但无法完成该init步骤。
运行go version回报go version go1.17.6 darwin/amd64
按照说明进行操作，gomobile安装似乎可以正常工作（在明确添加gomobile到我的路径后），但运行init或version失败。
gomobile: go install golang.org/x/mobile/cmd/gobind failed: exit status 1
go install: version is required when current directory is not in a module
Try 'go install golang.org/x/mobile/cmd/gobind@latest' to install the latest version
gomobile version unknown: cannot test gomobile binary: exit status 1, no required module provides package golang.org/x/mobile/cmd/gomobile: go.mod file not found in current directory …
