now I am conducting a iOS app with objective-c. I need to have a process bar with stepping to indicate the user registration procedure. How can I do it as the pictures?
I have made a custom view to implement the step indicator. Use CAShapeLayer to draw the circle and line. Check detail here: https://github.com/chenyun122/StepIndicator
The effect is:
OR
If you want to replace the core point by number, you could folk this project and modify the class AnnularLayer.swift to implement that.
If animation doesn't matter then you can used image.Change your image when you push view

in my Application I like to use the frontcamera to display the user on the iPad/iPhone. This is already working. Now I like to have a simple transparent "HUD" floating over the cameradisplay. It's just a circle which should fill itself, so it is quite a simple animation. Since I am new to iOS Developing I am not sure which framework to use. Unfortunately there is no canvas like in android/html.
Can you please recommend a framework for doing the animations?
I would be very happy for a nice start into my next assignment!
Ios creating simple camera overlay in Xcode how?
The above question provides an answer which should help you add your own view over the top of the camera feed.
Make this an instance of a custom UIView subclass of your own which has the desired functionality.
UIKit has plenty of functionality for an animation as basic as the one you are describing. Look at setting the corner radius of your view.layer object and maybe animating a view from bottom to top using [UIView animateWithDuration:].
I am updating my app to iOS 7 and wanted to improve the UI. I want to create a see through background like Control Center. So basically I have a button, which I would like to have a see through and "blurred" background like control center. Thanks!
There's nothing to stop you using a UIToolbar.
Create a UIView as a base view with clear background, add a UIToolbar anchored to it's edges so it fills the view and then add your other controls to your base view above the toolbar.
It'll look for example like this:
The blurring effect is not available as a public API. There are third party implementations available, such as FXBlurView, which I can recommend.
You shouldn't really be using a toolbar. It's called toolbar for a reason.
One way to go would be to take a snapshot image of your background and blur it (you can use UIImage+ImageEffects category included in Apple samples to achieve consistent effect).
You can then just crop the image to desired frame and use it as a background of your button.
Are you looking to have a 'dynamic' blur effect (like in Control Center)? It's still doable, but it makes things more complicated.
You can also create blur effects with GUPImage Framework here is a full tutorial about it iOS blur effect tutorial. The tutorial also explains why you shouldn't use toolbar for blur effect creation
I wonder which component is being used to create a selector option like the one used in iBooks where we can adjust the Font Size and also the Theme, but without moving to a new view controller.
In my application I would like to implement it giving 3 small options to the user to choose, but without moving the view controller being presented. Its a small square area with an arrow at the bottom or top side giving the impression where it's coming from. (Let me know if I am not clear with the explanation).
Does anybody know how to use it??
Thank you all in advance
ibooks is using UIView. In that UIView you can add any controls you like. You need to use delegate methods so that I can perform communication between two objects(send message to another object). You will be able to make you custom UIView as controls.
I want to implement a signature feature in my tabbar application. I want to add a subView to a UIScrollView or UIViewController (which ever is the more appropriate and easier). Which control should I use for it?
I want to pick the touch events on the signature view and draw on those points to get the signature. Any help would be highly appreciated.
You can use just a UIView for drawing points get touched. I needed to implement something like that and the following page was really helpful. It explains all with code. You may want to check it out.

Thank you in advance for any help, I am building a multipage iPad app,and each page has specialized calculations, they all work great, but i would like to make the user experience better with some simple line drawings that represent the calculations, I am comfortable with the drawing once i get a valid CGcontext working, and this is where my problem is. I already have a webview on each page and now I want to have a UIView pop open with my drawing when the user presses the calculate button, My UIview is called drawingView and it will pop open like I want but from what i have read all drawing needs to be done within the DrawRect method in order to use the correct context. I think some of my problem is the syntax for getting the context.
Thanks for any help

Ok, I had to do what I wanted the old fashioned way, but it just seems like you should be able to get the current context of a UIView from wherever I want. By calling the view and getting it's current context. But when I do ,I get errors about not getting the current context. So, I have to make my app differently using traditional UIViews classes and bringing them into my page.
