//給定6位十六進位制字串、獲取十六進位制顏色字串對應的顏色

+ (UIColor *)getColor:(NSString *)hexColor{

//定義無符號整型數值

unsignedint red,green,blue;

NSRange range;

    range.length = 2;

//提取指定下標索引、指定長度的十六進位制字串掃描字串取出的red、green、blue都為 0 ~ 255的整型值

    range.location = 0;

    [[NSScannerscannerWithString:[hexColor substringWithRange

    range.location = 2;

    [[NSScannerscannerWithString:[hexColor substringWithRange:range]] scanHexInt:&green];

    range.location = 4;

    [[NSScannerscannerWithString:[hexColor substringWithRange:range]] scanHexInt:&blue];

//返回通過十六進位制顏色字串獲取的顏色
