I need to create a slider which should have custom images for following slider parts:
left round corner image.
left part image which is selected part.
right part image which is
unselected or remaining part.
right corner image.
Thumb image.
Also i want to increase the thickness of the slider.
Please give me some suggestion or share some code snippets.
Thanks,
Look at setThumbImage:forState to change thumb image.
minimumValueImage and maximumValueImage for the images on the left and right hand side of the slider.
The track images can also be manipulated.
See "Customizing the slider's appearance" at http://developer.apple.com/library/ios/#documentation/uikit/reference/UISlider_Class/Reference/Reference.html

Hi I am trying to create custom buttons on unity (trapeziums). I successfully created the visible area on Photoshop and imported it as Sprite 2D UI as per the following image:
The issue arises, when I'm trying to select one of the buttons in game, their border overlap each other, since the transparent area is still being considered as part of the clickable button area. How can I remove this?
EDIT:
Practically when I import I want the squared boxes to not be counted with the image. I need the edges of the orange area to be cut flush with that and not the entire area(i.e. including the transparent boxes).
You may achieve this by using Alpha Hit Test Minimum Threshold. Take a look at this nice video tutorial.
There is one extra step that is not shown in the video but mentioned in the comments: you have to change "Mesh Type" to "Full Rect" and not "Tight" as it is.
Hope that helps.
The clickable area is based on the Rect Transform component of the GameObject. Adjust the width and height to the clickable area you want. You may have to crop your image in photoshop accordingly. If you select 'Gizmos' in the editor you can toggle viewing the click region.
I need it because the image is small and it's difficult to touch it on the mobile device. So I need to have bigger area of interactable zone but the image should stay small.
I believe the most proper way to make such button is like this:
Create a new Button, remove default child Text.
Set Width and Height of Button as you need for hitzone size.
Add Vertical Layout Group component to the Button.
Set Padding of the Vertical Layout Group to desirable difference between hitzone and visuals.
Remove default Image component. Set alpha of default Image component to zero.
Put your Image as child of Button.
Fix tint: drag (or otherwise set) the child Image to Target Graphic field of Button.
You need to set it up so that the image is inside a button object. Like this:
This way you can have the Button as big as you want and the Image can be any size. If you don't need the Button background image just make the color transparent in the image componenent of the Button object.
A surprisingly better way (in terms of ease and performance) is to add a text child element, even if you already have one. Leave the text empty and resize it however you like. It doesn't add any alpha.
Unity now have Raycast Padding property on Image component, edit these padding values will allow you to have more interactable zone for your button image. Note that you use negative value to extend the click zone.

I want to make a slider that is a line that is thin at the left (minimum)end and thick at the right (maximum) end and the button which slides between to change sizes between. I have tried setting minimum and maximum track images but this didn't seem to work. I have been able to set the images in IB but they stay the same size. Penultimate has something like I want when you pick the pen size. Any suggestions.
In image app i have to blur the selected areas of image. Something like create mosaic at selected area of image. i have to get each pixel color of selected area and then increase the size of each pixel. here is the reference link that i am using http://soulwithmobiletechnology.blogspot.in/2011/05/create-mosaic-with-your-image-part-1.html . But not able to implement this practically for selected area. Can any one have some sample for the same.
There are two solutions for this
1. Get the screen shot of the area where you want the mosaic effect and apply effect to the same portion. Then add the image(with mosaic effect) to the original image.
2.Get the pixel of the area you want to be effected and then gave effect to those pixels.*
First, I'm not talking about icon libraries or mockup tools/libraries.
I'm familiar with various icon libraries that people have created, but other than the stuff from the example code like UICatalog, I'm wondering if anyone knows of anyone who has created free libraries of custom button bitmaps (stretchable button images), slider handle/track bitmaps, etc Basically bitmaps to customize the look of standard controls for those controls (like buttons and sliders) that allow you to specify such bitmaps.
I'm also interested in any photoshop tutorials/templates on/for creating stretchable custom button images, bitmaps for slider parts, etc. (Afraid I'm not a huge PS god or anything.)
Anyone know of any resources like this for fancying up the standard controls?
I've been able to find several stretchable buttons by searching through my collections of sample code for: "stretchableImageWithLeftCapWidth"
From the Apple sample code, the UICatalog, BubbleLevel, iPhoneMultichannelMixerTest, avTouch, AQOffilineRenderTest, and TouchCells sample code all contain buttons with stretchable images.
Hope this helps!
Stretchable buttons is no problem - there's nothing special you need to do in Photoshop. Just make the image of the button stretchable and set the radius to that of any rounded corners you have on the button graphic.
Slider parts - I'm pretty sure you'd have to make your own UIControl from scratch.
To make a button in Photoshop, create a new file with transparent background, select the Shape tool, rectangle near the bottom of the tools, drag out a rectangle. Size doesn't matter™. For a rounded rectangle, click and hold the same tool, choose the rounded rect shape and set a corner radies (same radius as in stretchableImage later).
Double-click the layer right of the layer name to get the layer style popup. Check Color Overlay and set the color you want. Check Inner Bevel and make its size somewhere below half the height of the rectangle - I think 90 degrees for the Global Angle works well. A lower opacity and larger size makes the bevel look less chunky.
Ctrl-click (option-click) the graphics rectangle in your layer to select the button's outline. Deselect the bottom half of it by using the marquee tool (M) at the top of the tools. Select a light gray foreground color, nearly white. Create a new layer with the square icon under the layer list (Windows->Layers if not visible). Fill the selection of the new layer with the paint bucket, and drag down opacity for the layer until the 'matte laquer' effect of it looks right.
A simple button, but that's the gist of it.
