uicolor-hex-swift's Introduction

UIColor+Hex, now Swift.

Convenience method for creating autoreleased color using RGBA hex string.

    // Solid color
    let strokeColor = UIColor("#FFCC00").cgColor

    // Color with alpha
    let fillColor = UIColor("#FFCC00DD").cgColor

    // Supports shorthand 3 character representation
    let backgroundColor = UIColor("#FFF")

    // Supports shorthand 4 character representation (with alpha)
    let menuTextColor = UIColor("#013E")

    // "#FF0000FF"
    let hexString = UIColor.red.hexString()

    // Convert shorthand 4 character representation (with alpha) from argb to rgba
    if let rgba = "#AFFF".argb2rgba {
        let androidBackgroundColor = UIColor(rgba)
    }

    // Convert 8 character representation (with alpha) from argb to rgba
    if let rgba = "#AAFFFFFF".argb2rgba {
        let androidFrontColor = UIColor(rgba)
    }

uicolor-hex-swift's Issues

Could not find member 'CGColor'

I install this library via cocoapod but I got this error message

Please advice. Thank you.

Carthage build fails for WatchOS

When I run carthage update I get this error when it reaches the HexColor:

Swift 3 compatibility

Xcode 8 is out! Time to merge in Swift 3 branch.

Troubles with podspec

When trying to install pod I get the following error
Re-creating CocoaPods due to major version update.
Analyzing dependencies
[!] Unable to find a specification for UIColor_Hex_Swift (~> 2.1)

My cocopods version is 1.0.0

Undefined symbols for architecture x86_64

Tried to build the app on Swift 3.0, XCode version 8.2.1
I got the error on linking step.

Undefined symbols for architecture x86_64:
"(extension in UIColor_Hex_Swift):__ObjC.UIColor.(init (Swift.String, defaultColor : __ObjC.UIColor) -> __ObjC.UIColor).(default argument 1)"

Swift 2.0 does not support count(string) method.

for Swift 2.0 method to get character length for a string has changed. Its now String.characters.count

UIColor convert to hex problem!!

public func hexString(_ includeAlpha: Bool) -> String {
        var r: CGFloat = 0
        var g: CGFloat = 0
        var b: CGFloat = 0
        var a: CGFloat = 0
        self.getRed(&r, green: &g, blue: &b, alpha: &a)
        
        if (includeAlpha) {
            return String(format: "#%02X%02X%02X%02X", Int(r * 255), Int(g * 255), Int(b * 255), Int(a * 255))
        } else {
            return String(format: "#%02X%02X%02X", Int(r * 255), Int(g * 255), Int(b * 255))
        }
    }

return String(format: "#%02X%02X%02X%02X", Int(r * 255), Int(g * 255), Int(b * 255), Int(a * 255))

this line should be

return String(format: "#%02X%02X%02X%02X", Int(round(r * 255)), Int(round(g * 255)), Int(round(b * 255)), Int(round(a * 255)))

if don't round, after convert to hex, hex to UIColor could loss of precision

example rgb 27 34 48, after it will be 27 33 47

Use methods in objective c class in swift 4 project

Hi,
I have an objective-c class in swift 4 based project, I wanted to use this method, After successfully importing you pod in my objC class, methods had not been recognized.
I unlocked the UIColorExtension.swift and added @objc tag to your extension so i could use its method in my class

would you add this tag to your class for compatible it by objetive c classes ?

thanks

Support MacOS

Can you add support for MacOS
You can do it easily with an typealias

I've had to import it to my Mac Project from source rather than cocoapods. Would prefer Cocoapods.

A quick way to support
macos
Just replace top of
UIColorExtension.swift

import UIKit
@objc extension UIColor {

WITH


#if os(iOS)
//---------------------------
//iOS
//---------------------------
import Foundation
import UIKit
typealias AppColor = UIColor

//---------------------------
#elseif os(macOS)
//---------------------------
//macOS
//---------------------------
import Cocoa
typealias AppColor = NSColor

//---------------------------
//#else
// os(tvOS) || os(watchOS)
//---------------------------
#endif


@objc extension AppColor {
    /**
     The shorthand three-digit hexadecimal representation of color.
     #RGB defines to the color #RRGGBB.
     
     - parameter hex3: Three-digit hexadecimal value.
     - parameter alpha: 0.0 - 1.0. The default is 1.0.
     */
    public convenience init(hex3: UInt16, alpha: CGFloat = 1) {
        let divisor = CGFloat(15)
        let red     = CGFloat((hex3 & 0xF00) >> 8) / divisor
        let green   = CGFloat((hex3 & 0x0F0) >> 4) / divisor
        let blue    = CGFloat( hex3 & 0x00F      ) / divisor
        self.init(red: red, green: green, blue: blue, alpha: alpha)
    }
...}

Swift 5 was throwing errors about failable inits and non failable in
I had to change
init

   public convenience init(_ rgba: String, defaultColor: NSColor = NSColor.clear) {

TO init?

public convenience init?(_ rgba: String, defaultColor: NSColor = NSColor.clear) {

XCode 11 showing expression is ambiguous without more context

i have this little piece in my code

UIView.animate(withDuration: 0.1, animations: { _ in
      self.highlightedCell!.backgroundColor = UIColor.init(hex6: 0xF7DB69)
})

and it complains with Type of expression is ambiguous without more context
i cant figure it out.. any clue?

Dependency "UIColor-Hex-Swift" has no shared framework schemes

I'm using Carthage 0.9.3 and get this error when trying to use UIColor-Hex-Swift:

*** Checking out UIColor-Hex-Swift at "1.2"
*** Skipped building UIColor-Hex-Swift due to the error:
Dependency "UIColor-Hex-Swift" has no shared framework schemes

Doesn't work with the latest changes in swift

Argument Labels Don't Match Overloads Issue

Hey,

Great git guys.

I followed the installation process and I get an error:
Argument labels '(rgba:)' do not match any available overloads')' when i try to add this line in my App Delegate

    UITabBar.appearance().barTintColor = UIColor(rgba: "#12296f")

Do i have to add an import statement? If so what is it? What am i missing?

Thanks a lot

Can't find package with Xcode 13.1

Hi,

Thanks for offering a great package.

Swift Package Manager can no longer find UIColor-Hex-Swift after updating to the latest version of Xcode.

Any idea why?

Thanks!

This bundle is invalid

[see the Core Foundation Keys at

Some people always get used to the 0.0~1.0 way alpha. Will you support?

in case you want to extend to support rgb(r,g,b) and rgba(r,g,b,a) strings

not sure how efficient these are yet since they use advance o(n) parsing for likely utf8 single byte strings

you'd call this method in the else not hex clause

func rgbaStringToVals(rgba: String) -> (r: CGFloat,g: CGFloat,b: CGFloat,a: CGFloat) {
var red = CGFloat(0.0)
var green = CGFloat(0.0)
var blue = CGFloat(0.0)
var alpha = CGFloat(1.0)

if rgba.hasPrefix("rgba(") {
    let sInd = advance(rgba.startIndex,5)
    let eInd = advance(rgba.startIndex,count(rgba)-1)
    var num = rgba[sInd..<eInd]
    var loc = num.componentsSeparatedByString(",")
    if count(loc) < 4 {
        println("unable to find 4 color values from string \(rgba) default color used rgba(0,0,0,1)")
    }
    else {
        red = CGFloat(loc[0].toInt()!)/CGFloat(255.0)
        green = CGFloat(loc[1].toInt()!)/CGFloat(255.0)
        blue = CGFloat(loc[2].toInt()!)/CGFloat(255.0)
        alpha = CGFloat(loc[3].toInt()!)/CGFloat(255.0)
    }
}
else if rgba.hasPrefix("rgb(") {
    let sInd = advance(rgba.startIndex,4)
    let eInd = advance(rgba.startIndex,count(rgba)-1)
    var num = rgba[sInd..<eInd]
    var loc = num.componentsSeparatedByString(",")
    if count(loc) < 3 {
        println("unable to find 3 color values from string \(rgba) default color used rgba(0,0,0,1)")
    }
    else {
        red = CGFloat(loc[0].toInt()!)/CGFloat(255.0)
        green = CGFloat(loc[1].toInt()!)/CGFloat(255.0)
        blue = CGFloat(loc[2].toInt()!)/CGFloat(255.0)
    }

}
else {
    println("String \(rgba)does not have #hex or rgb() or rgba() format default color used rgba(0,0,0,1)")
}
return (red,green,blue,alpha)

}

Ambiguous use of init(_:defaultColor:)

Does anyone have ideas about how to solve it?

XCode 8.1
Swift 3.0

Prefix

Why this:

        guard rgba.hasPrefix("#") else {
            throw UIColorInputError.missingHashMarkAsPrefix
        }
        
        let hexString: String = String(rgba[String.Index.init(encodedOffset: 1)...])
//...

Not:

        var hexString = rgba
        if hexString.hasPrefix("#") {
            hexString = String(hexString.dropFirst())
        }
//...

Is there a static version?

Swift Playgrounds 4 does not allow for dynamic libraries, do you have a static version?

Failable init?

Any considerations to make the init method failable? Or provide an optional failable init?

It makes much more sense to me the init to be failable in case of an invalid string, as it allows for much better error handling than printing a message in the console.

Argument labels '(rgba:)' do not match any available overloads

Privacy manifest required by Apple

Hi team,

Starting with Spring 2024 Apple requires third-party SDKs to add a Privacy Manifest file.
https://developer.apple.com/support/third-party-SDK-requirements/
https://developer.apple.com/documentation/bundleresources/privacy_manifest_files

Does this SDK need a privacy manifest? If yes, is there any plans to add a privacy manifest?

Thanks,
Duan

set proper name of pod

to not get mistakes
pod 'UIColor-Hex-Swift'
or
pod 'UIColor_Hex_Swift'

Or specify it in radme

Change MinimumOSVersion to 8.0 to support Carthage builds

When trying to archive my project, I get the following error:

This can be fixed by setting MinimumOSVersion to 8.0 in your Info.plist file.

The different name between SwiftPackageManager and Cocoapod

When I create third part SDK depend on UIColor-Hex-Swift , because of the different name between SwiftPackageManager and Cocoapod, I cant import in the SDK to my app.

when I use the SwiftPackageManage name in my SDK, I cant pod trunk push my SDK to remote, but when I use Pod name in my SDK, I cant use SwiftPackageManage to install my SDK in my App.

Invalid hex strings produced from wide display colors

The documentation for getRed(: green: blue: ) explains that older versions of iOS always set the values to a range within 0 and 1, but not any more. When one of these returns outside the expected range, hexString(:) produces invalid hex codes (for example, #54A8FFFFFFDF).

Cocoapods Integration

Any plans to support Cocoapods with this?

version 4.0.0 it's not yet on cocoapods

Hi,
When I try pod 'UIColor_Hex_Swift', '~> 4.0.0' it cause error on pod update. It seems version 4 it's not updated on cocoapods yet.
I used pod 'UIColor_Hex_Swift', :git => 'https://github.com/yeahdongcn/UIColor-Hex-Swift.git' and it works

Minimum deployment target using Carthage

Using Carthage to install UIColor-Hex-Swift and my project's deployment target set to iOS 8.0, I get this error when building:

"Module file's minimum deployment target is ios9.0 v9.0"

Looking at the pod spec, it seems that the minimum version should be 8.0.

No such module 'UIColor_Hex_Swift'

No such module 'UIColor_Hex_Swift'
How can i fix this problem?

Developer From Android To iOS, #ARGB #AARRGGBB is Accepted better.

Color in Android is #AARRGGBB or #ARGB, So iOS developer trans from Android developer can accept that easier than #RRGGBBAA. May be Support it, UIColor-Hex-Swift will be populer than befor.

Support Application Extensions

When including this library in an application extension, I get the following warning:
Linking against a dylib which is not safe for use in application extensions. All that should be required to supress this warning is to set the target’s “Require Only App-Extension-Safe API” build setting to Yes.

Archive export issues when used as a Swift Package

When I removed the UIColor-Hex-Swift from Swift Package dependencies the issue was resolved. Please note that using it with Cocoapods does not reproduce the above issue.

Updated count() for Xcode 7 beta 5

I had to update count(hex) to hex.characters.count to make this work with Xcode 7 beta 5
I forked your repository, but thought you should know.

Issue when attempting to install.

'substring(from:)' is deprecated in Swift 4

Hi, in Swift 4, your library says 'substring(from:)' is deprecated: Please use String slicing subscript with a 'partial range from' operator. in too many places. Can you fix it?

Swift Package Manager

I see that the support for SPM has been added, when you will release a new version in order to be able to add the package to SPM?

Now I have the following error:
