color-picker-for-ios's Issues

Swift support

It would be great if you added Swift support

Carthage package manager

It would be great if you added support for the Carthage package manager

Sometimes dragging to select a color will return to the original position

NaN with HRBrightnessSlider

I have had to make this change to avoid my app crashing

Line 191:

if (brightnessCursorX < 0 || isnan(brightnessCursorX)) {
return;
}

(Added NaN check). The problem occurs during setting the color for refreshing the view with new data, via an async queue.

Pod download not up to date

The version I just obtained using cocoa pods has some bugs that are fixed in your current master. For example, programmatically setting the color doesn't have any effect on the views in the pods version, but in your master branch, it has been fixed and does have the expected effect.

Support Xcode 12.2

The SPM doesn't support Xcode 12

layout not aligned properly in all devices

6s it is perfect but in 4s everything overlaps,
i have given auto layout to the main view, what should i do..
to make it view perfect in all devices.

get number of tiles in row

i want to adjust view based on number of tiles to be displayed in a view, because the number of tiles is not fixed it changes as per device

so is there any way to get number of tiles.

Cocoapods Installation

When I run it, I get the following error:

[!] An error occurred while processing the post-install hook of the Podfile.

undefined method `project' for #<Pod::Installer:0x007f86f39fef80>

Programmatic Allocation

For those of your having problems with wrong-spaced frames, just add the following code to your controller:

    _colorPickerView.frame = CGRectMake(0.0f, 0.0f, self.view.frame.size.width, self.view.frame.size.height);
    _colorPickerView.colorInfoView.frame = CGRectMake(8.0f, 8.0f, _colorPickerView.colorInfoView.frame.size.width, _colorPickerView.colorInfoView.frame.size.height);
    _colorPickerView.colorMapView.frame = CGRectMake(84.0f, 80.0f, self.view.frame.size.width - 84.0f - 8.0f, _colorPickerView.colorMapView.frame.size.height);
    _colorPickerView.brightnessSlider.frame = CGRectMake(0.0f, 104.0f, self.view.frame.size.width, self.view.frame.size.height - 104.0f);

color Picker size is not fitting certain devices .. it's perfect for iPhne x and got issues with iPhone 12 and lower devices

is there anyway top resize the colorpicker?

Swift compatibility

How can I use this in Swift project?

I have added using Cocoapods but I am getting "No such module" error.

Is it possible get color name from selected color code ?

In my scenario I want to get color name after selected the color in color pad, Because in Xcode already one property is available to get the color name using "accessibilityName" word. But this is giving me a color name, After searching on google with that color name it gives different one.

Not easy to pick white color

Support Orientation

Please support orientation.

Make HRBrightnessSlider Animated When Moving

It looks a lot better. I've added this to my current project. Played around with all the animation duration, this works the best.

• (void)updateCursor {
  CGFloat brightnessCursorX = (1.0f - (self.brightness.floatValue - self.brightnessLowerLimit.floatValue) / (1.0f - self.brightnessLowerLimit.floatValue));
  if (brightnessCursorX < 0) {
  return;
  }
  CGPoint point = CGPointMake(brightnessCursorX * _controlFrame.size.width + _controlFrame.origin.x, _brightnessCursor.center.y);
  [UIView animateWithDuration:0.1
  delay:0
  options:UIViewAnimationOptionCurveEaseIn
  animations:^
  {
  _brightnessCursor.center = point;
  _brightnessCursor.color = self.color;
  }
  completion:^(BOOL finished)
  {

      }];
  

  }

colorMapView can not show

follow the step of README
colorMapView can not show
HRBrightnessSlider can show
HRColorInfoView can show

what's wrong with my step?

Support iPad

Do you have any plans to modify this to support the iPad as well?

How to use FullColor ?

Hi,
Like Title , I Use Color Picker Without Interface Builder .
And Set saturationUpperLimit.

colorPickerView.colorMapView.saturationUpperLimit = @1;

And How To Use FullColor Without Interface Builder ?

Thank you to answer.

Always black unless Slider is moved.

The HRColorPickerView always returns black. When I move the slider I can see it is purple, but the brightness is always set to 0 on init. I have set it up just like the example project.

Crash

Getting crash due to hsvColor { preconditionFailure() }()

3.0.1 to CocoaPods repository

Probably 3.0.1 can be pushed to cocoapods repository

If I mention in Podfile, CocoaPods cannot find version

pod 'Colorful', '~> 3.0.1'

Color Picker Only Shows Red colors

Testing this on my iPhone, I am only able to see red colors in the gradient of color options. I don't see green, yellow, blue, or any of the other colors that appear in the image.

Oddly enough, a similar issue occurred for me while using another color picker library.

Do you have any idea why this is happening?

Can't pick up white, and back color from the ColorPickerView

I like the color picker. But unfortunately, it is NOT easy to get a white color on there. Its frustrating. I can't seem to get the white color for the background. Since white & black are the main colors that users will use as the background, so I think changing color picker will be needed here.
Do you have any recommendations ?

Thanks.

Problem displaying Button

Hello and first of all thanks for sharing this awesome ColorPicker.

But there ist one problem I'm currently facing.
When I'm adding another object (like: button, slider, uiView ...) into the scene, it won't display at runtime nor in xCode 6 new Debug Screen.

I don't now the Problem. Maybe You?

can't show

I did install the library from pod and followed the sample code.
View can't be shown, because colorPickerView frame is 0,0,0,0 !
Please fix
Roberto

Also, what about a "close" button to dismiss colorPickerView ?

how to initialize colorPicker.color

I use Color-Picker-for-iOS by storyboard and do implement - (void)viewWillAppear:(BOOL)animated but it doesn't work.Every time I segue to the scene colorpickerview always show the default color(redcolor，the upper left corner of the square).

@implementation LLColorPickerController
-(void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
self.colorPickerView.color = [UIColor blueColor];//self.color;
}

Could you please add pod information in README?

how to write Podfile?
like this maybe?

platform :ios, '7.0'
pod 'Color-Picker-for-iOS', '~> 0.1.1'

Is 0.1.1 the latest version?

ARC

does not compile for ARC (auto reference counting) projects
is there a ARC version somewhere ?

UI code don't run on main thread

HRColorMapView.m

• (void)_init;
  at row: 184

---

[_initializeQueue addOperationWithBlock:^{
     [self createColorMapLayer];   ---------------> this code may be have problem.
    dispatch_async(dispatch_get_main_queue(), ^{
                                                    (2) ------------> maybe code  here , there will run on main thread

Better directions for customizing UI

Can you include better directions for customizing UI and using it with Autolayout? The various delegate methods and what needs to be implemented is not well-documented and prevents people from using the framework beyond the default.

How to use only Circle Color Picker?

Your Color Picker is very easy to use to compare others. But I want to use only circle colour picker, I have a UIView in that view I want to display this circle Color Picker in centre with out slider (beside the circle color picker). Is it possible? If yes please guide me.

In ColorPicker class I tried to hide addSubview(brightnessSlider) and addSubview(colorMapCursor) in private func setup() . But it is not working.

For example see my image, I want total view like this...
Here I wan to remove slider completely and adjust the color circle in to centre of the view (OR) at least hide slider and adjust the color circle in to centre of the screen.

And how to stop continuous reading values from ColorPicker? Which means I want to call this handleColorChanged function only one time that is last value. Because of I want to call one more function in to this.

Thank you.

colorMapView does not follow orientation changes

When changing from portrait to landscape, colorMapView remains in it's portrait layout. Any fix for that?

Thanks.

How to get hex color value?

Casting Hex Colors

Casting your hex values on info view is loosing some precision, here is the updated method:

    CGFloat rFloat, gFloat, bFloat, aFloat;
    [self getRed:&rFloat green:&gFloat blue:&bFloat alpha:&aFloat];

    int r, g, b;
    r = (int)ceilf(255.0 * rFloat);
    g = (int)ceilf(255.0 * gFloat);
    b = (int)ceilf(255.0 * bFloat);

    return [NSString stringWithFormat:@"#%02x%02x%02x", r, g, b];

Oh, this was already fixed a few days ago.
