# UIColor-Hex

Convenience methods to convert UIColors to from hex/css value/strings.

## Usage

### Creating a colour from a hex value

Use the `colorWithHex:` class method:

```objc
UIColor *color = [UIColor colorWithHex:0xffcc00];
```

The hex value is in the format RRGGBB, as you would expect.
You can specify a 32-bit hex value if you want an alpha component:

```objc
UIColor *fadedColor = [UIColor colorWithHex:0x33ffcc00];
```

If you do not specify an alpha "prefix" value, the default will be fully opaque (alpha = 0xFF).

### Retrieving the hex value from a colour

```objc
uint hexValue = [color hex];
// hexValue is 0x33ffcc00
```

This will always return a 32bit value, including the alpha component.

You can also get a hex string:

```objc
NSString* hexString = [fadedColor hexString];
// hexString is @"0x33ffcc00"
```

This will return a string with the color described as a 32bit hex value, including the `0x` prefix.

### Creating a colour with a CSS string

This only support the standard RGB css strings, not the `argb()` format. If there's interest, I might add support for it.

```objc
UIColor *color = [UIColor colorWithCSS:@"ffcc00"];
UIColor *sameColor = [UIColor colorWithCSS:@"#ffcc00"];
```

You can include the hashmark before the colour, but it's not required.
This also supports 32bit colour strings, including the alpha component in front:

```objc
UIColor *fadedColor = [UIColor colorWithCSS:@"#33ffcc00"];
```

### Retrieving the CSS string from a colour

```objc
NSString* cssString = [color cssString];
// cssString is @"#ffcc00"
```

The resulting string will always include a hashmark. If the colour is fully opaque, the alpha component will not be included in the string. Otherwise, the alpha component will be prepended before the other colour components:

```objc
NSString* cssString = [color cssString];
NSString* fadedCssString = [fadedColor cssString];
// cssString is @"#ffcc00"
// fadedCssString is @"#33ffcc00"
```
