iOS中怎么将#35b665（16进制）的颜色值赋给image，请大神帮忙

从网络端获得的image是透明的，同时得到了一个#35b665（16进制）的值，怎么给image赋上这个值

解决方案

• (UIColor*) colorWithHex:(NSString *)hexValue alpha:(CGFloat)alphaValue
  {
  unsigned int red,green,blue;
  NSRange range;
  range.length = 2;
  range.location = 0;
  [[NSScanner scannerWithString:[hexValue substringWithRange:range]] scanHexInt:&red];
  range.location = 2;
  [[NSScanner scannerWithString:[hexValue substringWithRange:range]] scanHexInt:&green];
  range.location = 4;
  [[NSScanner scannerWithString:[hexValue substringWithRange:range]] scanHexInt:&blue];
  return [UIColor colorWithRed:(float)(red/255.0f) green:(float)(green / 255.0f) blue:(float)(blue / 255.0f) alpha:alphaValue];
  }
