I'm trying to let the users of my app cancel an active alarm using a slider, like the timer app or the iPhone lock screen.
Is this control available to us as developers? If so, what's the name of it, and do I need to add it programmatically? I do not see it in the interface builder.
Thank you!
You could always try this on cocoacontrols.
Slide to unlock control
There you go,

It's not a standard control - you'll need to create it yourself.
However, I think you should be able to customize the slider control. You can change the look and feel of that by supplying your own graphics, and it should be easy to simulate the behavior of the lock slider (such as making it slide back to 0 if it doesn't get all the way across).

I want to create view in which when user use in portrait mode then two images scroll in scroll view and when user change mode as landscape then both image views add and become single view. I show this function in restoration hardware apps.I like that so i want to make my apps like that? how do that?
What you ask, is a simple implementation that I could do for you. But then again, you would't learn anything and you would probably come here and ask again. I won't give you the fish, I will show you a way of catching it. Check this tutorial, to learn how to handle rotation and then manipulate your views the way you want:

In my profile you have my personal email, after you learn that, if you need more help, count with me.
hey guys,
i am working on a ebook reader and in its course i wanted to allow the reader to reduce/increase the brightness accordingly. what i tried is ,placed a UISlider and gave the values as 0 and 1 for min and max respectively. I placed a imageView on the main view and aplied alpha component to the uiview which responds to the slider accordingly.
i succeeded but i know that it doesn't save the battery life of the ipad.
are there any predefined methods or framework which enables us to alter the brightness of the device.
thank you in advance
There is a private api call GSEventSetBacklightLevel(float). But if you are planning to submit this to the app store it will get rejected.
There is now of doing this via the public API, you could use, like you stated, a semi tranparent view with a black background over the window to make it look like you can control the brightness.,
I'd like to take a sneak picture while user is playing my app and show the pic after a certain time period.
If that's not possible, I'd like to decrease the camera view size.
Is that possible?
Thank you
I dont think Apple will allow you to "sneak a pic" of the user. Your app may or may not get rejected, you may want to think of another way to allow the app to take snap of the user, maybe an alert, much like the Location dialog, asking the user to allow the action.
UIImagePicker *imagePicker.cameraViewTransform =
CGAffineTransformScale(imagePicker.cameraViewTransform, 1.0f, .5f);
You can change the by using this one.
It is completely possible. Just have a UIView overlay your UIImagePickerView. Use the
-takePicture method to randomly take a picture without them pressing anything.
I need to make an iphone app like USA Free that's in App Store.
Can anybody, please, tell me what kind of app is this (window or view based) and how it is possible to make horizontal slide effect when changing views?
Thank you!
For transitions, take a look at http://developer.apple.com/library/ios/documentation/UIKit/Reference/UIView_Class/UIView/UIView.html#//apple_ref/occ/clm/UIView/transitionWithView:duration:options:animations:completion:
All apps contain one (or more) windows and views. You might want to start with the basic of creating an app. http://developer.apple.com/library/ios/referencelibrary/GettingStarted/Creating_an_iPhone_App/_index.html#//apple_ref/doc/uid/TP40007595
View based just means the project comes with a default class already setup. You can put anything you want in that class. Window based is just if you want to create all the classes your self. Theres not much difference, so it doesn't really matter which you choose as long a you know how to create the horizontal slide effect your going for.
I need to do something similar, where an animation highlights the text of a button to show that it must be slided to do something. Just like that unlock thing on the iPhone. How is that done? Is there a tutorial how to achieve this effect?
The searchlight-effect is also included in the three20-project, if you are planning to build such a control on your own.
There's a project here: http://altosdesign.com/iphonesdk/SlideToCancel.zip which has the effect you're after.
