具体实现如下：

通过对象调用下面方法，传入色值字符串，返回UIColor对象为title的textColor设置颜色>>

//传入的色值为：#3f51b5self.title.textColor = [selfcolorFromHexRGB:@"3f51b5"];//转换16进制色值为UIColor对象- (UIColor *) colorFromHexRGB:(NSString *) inColorString{    UIColor *result = nil;    unsigned int colorCode = 0;    unsigned char redByte, greenByte, blueByte;        if (nil != inColorString)    {        NSScanner *scanner = [NSScanner scannerWithString:inColorString];        (void) [scanner scanHexInt:&colorCode]; // ignore error    }    redByte = (unsigned char) (colorCode >> 16);    greenByte = (unsigned char) (colorCode >> 8);    blueByte = (unsigned char) (colorCode); // masks off high bits    result = [UIColor              colorWithRed: (float)redByte / 0xff              green: (float)greenByte/ 0xff              blue: (float)blueByte / 0xff              alpha:1.0];    return result;}
