i actually need to save 96 images in the temp file Iphone.
Indeed i have a slider with 96 values and for each value
i have differents images, if i want to do that, this is to have
a movie with the 96 images who scroll when i move the slider .
Thanks for your help and sorry for my english.
You'd probably be best of storing them in NSArray.
The reason for this would be easier animation (later on, if needed) since the UIImage also holds a property named images of NSArray type.
There are many examples of how to read/write arrays to file. For example: http://mobiledevelopertips.com/data-file-management/read-and-write-array-dictionary-and-other-collections-to-files.html
Edit: if all your images are known at compile time then you should simply name them frame_0.png to frame_95.png. Load them into NSArray at application launch and use the images simply as:
(UIImage *)[array objectAtIndex: x]

In the app that I am creating, I need to remove the background of the image except for the people or person in the image. I have searched many links, but i didn't find any relevant information .
For eg : Girl should be visible excluding the nature background.
Can anyone please provide me some information regarding this as whether is it possible ?
Thanks in advance
Note:1. If you have Another UIImageView with backgroundImage then use bellow logic
When you want to Cropped Image at that time just hide that backgroundImage with this bellow code..
[yourBackgroundImage setHidden:YES];
write this code before you write code of Cropped image with bezierPath, After if you want to display that backGroundImage Again then Display it with bellow code..
[yourBackgroundImage setHidden:NO];
2. If you want to Remove inbuilt BackgroundImage then use OpenCV..
see some example here may be you get something which is helpful to you... This Link
i hope this answer helpful to you..
:)

I am just starting conceptually for a meme-generator (writing texts on images)
conceptually like this
But more for an iPhone. what could be the way to achieve this and Draw some text on image
and return an image with text.
I need a 1000 foot view of how it will be done. conceptually?
Conceptually:
create a UIView
add UIImageView(s) to UIView
add UITextView(s) to UIView
create ImageRepresentaion Image from UIView

Is there any way by which I can add a UISlider to control the brightness on UIImagePickerController camera?
The only way to do something like this is to not use UIImagePickerController and to create your own camera view. You take the feed from the camera and render it to the view directly. You can then edit the feed by changing the brightness etc...
There are a few really good videos from WWDC 2012 (I think session 510 and 511) that will explain how to do all of this well. It's actually fairly straight forward.
You can then add a button which acts as the camera button and saves the image.

I have a tableView with some images in it. I would like to be able to drag these images around the screen. I have created a custom view which is the size of the visible screen that contains an onTouch method handler and also contains onDraw to allow me to drag an image. I would like some opinions on the best way to get the images from the table view and add them to the custom view when the action_down event is triggered (enabling the image to be dragged). Should I add the tableView to the custom view? Would I beable to detect the image boundry?
Thanks
Solved!
I created onTouchListener for each of the images which created an object that can be passed to the custom view when MotionEvent.ACTION_DOWN is fired. The custom view is then responsible for redrawing when MotionEvent.ACTION_MOVE is fired.

need to draw line touchBegan, touchMove function instead of drawRect function on class derivated from UIView Subclass
Apple's documentation does an excellent job of introducing all the concepts and details you'll need. Please read first, and ask specific questions if you have trouble understanding something.
Subclass a UIView. Implement a drawRect in that custom subclass. Call setNeedsDisplay on a visible instance of that class. Use CG or Core Graphics commands to stroke a path. See Apple's Core Graphics reference documents on developer.apple.com.
