IOS 16进制颜色字符串转UIColor

把字符串截出来就可以了

• (UIColor ) stringTOColor:(NSString )str
  {
  if (!str || [str isEqualToString:@”“]||str.length < 7) {
  return nil;
  }
  unsigned red,green,blue;
  NSRange range;
  range.length = 2;
  range.location = 1;
  [[NSScanner scannerWithString:[str substringWithRange:range]] scanHexInt:&red];
  range.location = 3;
  [[NSScanner scannerWithString:[str substringWithRange:range]] scanHexInt:&green];
  range.location = 5;
  [[NSScanner scannerWithString:[str substringWithRange:range]] scanHexInt:&blue];
  UIColor *color= [UIColor colorWithRed:red/255.0f green:green/255.0f blue:blue/255.0f alpha:1];
  return color;
  }
