I need to implement an app who recognise gesture (single/double tap, pan,pinch, rotation, swipe) and display an alert view.Can you help me?
Apple’s iOS Developer Library contains what you are searching for. For gesture recognition, e.g., take a look at the following page: Event handling guide for iOS; AlertViews can be found in the UIKit User Interface Catalog
Without having a more specific question, I cannot help you any further.

I have a client that adamantly insists on a solution with embedded camera in terms of having a ContentPage with an camera stream and custom buttons and icons, similar to https://github.com/pierceboggan/Moments, or at very least as I understand it seeing as it is a Snapchat clone. And my client wants similar swipe capabilities as to how navigation works in Snapchat.
However, as far as I can tell most of what is utilized in that solution has been deprecated.
I have suggested using the Media Plugin https://github.com/jamesmontemagno/MediaPlugin but they're not satisfied with the camera being pushed on the stack.
I've looked into implementing it natively and using dependency injections but it appears to be an overwhelming amount of work just to implement the most basic functions, particularly for Android's Camera2.
I'm hoping someone can provide me with good news of an easier alternative or an alteration to either Moments or Media Plugin or anything similar that will facilitate the requirements or if my only option is time consuming and complex?
From the code of Moment, you can do what you want to achieve. I did this for iOS.
You will have to create a custom renderer to display the camera page. You will be able to add buttons on top of it.
You could try this example which use custom renderer to add a take photo button and switch camera button on the camera view. Which is able to use on iOS and Android platform.

Camera View with custom button page:
I am creating a camera app, hoping to have similar look as iOS 7's built-in camera app, and adding a few more custom buttons. I am following example of UIImagePickerControllerDelegate but it does not fit my purpose because I want the first screen showing the view (i.e. same as iOS' camera). The UIImagePicker requires user to press a button to bring up the camera mode. I have a feeling that I should follow AVCaptureSession but I am lost in the lengthly documentation (I'm a Rookie). Can anyone show me a high-level step, or any sample source code will be highly appreciated :)
As you already guessed, UIImagePickerController has limited functionality and may not fit your needs. For an AVCaptureSession example, take a look at these (referenced 10th Feb 2014):

I am developing a Cocoa Application for Mac OSX. I intend to have multiple NSScrollViews and I'd like all of them to scroll at the same time if one of them is selected and scrolled.
I saw for UIScrollView there is a method "scrollViewDidScroll" that I could do this with an iPhone application.
Is there anything similar for NSScrollView or a way to go about doing this? Any help would be greatly appreciated.
Your solution is going to require that one of the scroll views will need to receive notifications that the other scroll view is being scrolled.
Apple actually provides some very nice documentation on Synchronizing Scroll Views, which also has some sample code snippets as part of it.
I'm developing a Kiosk-Mode Application and I want to prevent the notification center gesture (swipe down from top). Since the Application isn't distributed using the AppStore private APIs are allowed.
I have skimmed through the UIKit class dump but did not find any hints on how to disable it (resp. don't know where to look, tried UIApplication and UIWindow).
Has anyone tried this yet and had success?
It may be a little tricky, cause you are trying to disable native iOS function like all-fingers swipe gesture on iPad and so on. Some people use this method to define different notification center swipe side:
statusBarHidden = YES
and then you can redefine side:
setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft
as example.
I think you couldn't find any hacks to prevent iOS notification from showing at all. As last approach you can get some profit from dealing with jaiblroken features on unlocked devices...
I'm a beginner in IOS but I need to show a video when the app is launching.
Please Can you help me?
If is impossible to implement a video on a splash view, there are any idea to create that?
Thanks.
If I have an orthographic mistake, sorry I come from Spain. ;D
The "splash" screen can only be an image to be used as a placeholder until your app is able to start up. Even if you found a way to get a video to play, which I don't think is possible, it is against Apple's HIG for how the startup screen is supposed to be used.
It would be possible to load your video in its own view immediately after the splash screen. You would need to check for a first time run to determine whether to show it, unless you plan to show it each and every time. Hope this helps.
