iOS开发-16进制颜色转换

项目中经常会用到颜色转换,有的是通过十六进制转成数字转颜色,想简单的点直接通过字符串转一下,简单扩展了一下分类UIColor,代码如下: +(UIColor *)colorWithHex:(NSString *)hexColor{ return [self colorWithHex:hexColor alpha:1.0f]; } //http://www.cnblogs.com/xiaofeixiang iOS技术交流:228407086 +(UIColor *)colorWithHex:(NS

前端笔试题：拍扁多维数组、提取URL中的参数变成对象、实现string的trim()函数、判断Email地址、16进制颜色转rgb格式

(1)拍扁数组 这是一个著名互联网公司今天的前端笔试题:多维数组维数不定,如[2,4,1,[2,3,4,[1,2],5,3],3,8]拍扁为[2,4,1,2,3,4,1,2,5,3,3,8].维数不定,应该要用递归: 答案: function flatten(arr){ var arrLength=arr.length; for(var i=0;i<arrLength;i++){ if(arr[i].constructor==Array){ arr.splice(i,1,flatten(arr[
