问题 Currently I am developing a game which needs a stop watch say 1 minute,when user taps the play button it enters the game screen,I want the to run the stop watch count down of 1 minute 01:00,00:59,00:58 etc. For that reason I searched and found NSTimer would be the ideal choice to implement a stop watch.Hence I took a label,created an instance of NSTimer,assigned time interval and started decrementing the value in timer label,i.e.: -(void)viewDidAppear:(BOOL)animated { self.stopWatchTimer =

问题 My browser extension embeds a div item to webpages opened by browser on the fly. div contains several children items such as buttons, spans, input boxes etc. Problem is when div is inserted to page, page's css affects the div and it's contents. For example if the page has a css such as : span { text-shadow: 1px 1px 1px blue; } then the spans in my on the fly added div have blue text shadows. What i'm doing to fix this is to set any possible directive that might affect my div's content with

compass常用模块（reset、css3、layout篇）

由 冷暖自知 提交于 2020-01-05 13:55:58
compass内置五大模块：reset、css3、layout、typography、utilities（官网： http://compass-style.org/reference/compass/ ） 1、reset：浏览器样式重置模块，用来减少不同浏览器之间的差异性 reset把对样式的重置封装成了一个又一个的mixin，通过@import "compass/reset/utilities"来引入这些mixin的集合，有时不需要进行全局的样式重置，可以单独重置某一块。 用法： @import "compass/reset/utilities"; @include reset-html5; 可以使用normalize替换掉compass的reset模块 (1)使用包管理工具，npm install normalize.css (2)使用compass的normalize的插件 使用命令行指令“gem install compass-normalize” 这里使用第二种方式： 1.在config.rb中引用插件 require 'compass-normalize' 扩展： <1>require 'compass/import-once/activate'用来设置，在不同代码位置，重复引用时只需一次即可，避免代码冗余。实在需要重复引用时加上“！”即可，如 @import

How do I reset my Arduino Mega2560 with my C# application?

由 ╄→гoц情女王★ 提交于 2020-01-04 07:20:02
问题 I noticed the Arduino IDE automatically resets on startup/exit by the built in serial application due to one of the hardware flow control lines (DTR) of the FT232RL is connected to the reset line of the ATmega1280 via a 100 nanofarad capacitor. When this line is asserted (taken low), the reset line drops long enough to reset the chip. I noticed that behaviour does not happen with my serial C# application. I would like the reset feature to work with my C# application. What am I not doing to

问题 I want to reset all sequences to 0. This somehow does not work.

问题 This question already has answers here : How do you reindex an array in PHP? (19 answers) Closed 3 years ago . Forgive my noobness again. I've got an array with 20+ values in it and I take every 20 to shove in my database and then chop them off the front of the array. I want to restart the array's indexes back to 0 but instead it starts at 20 even when I use array_values. I also tried array_merge(array(), $string) What to do? if($x%20 == 0){ var_dump($string) // original array get_string(
