I have issue with loading image from /Library/ in both iPhone Simulator and on the real device.
This issue happened on only iOS-8.
Could any one please tell me what is the issue and how can I resolve it.
Thanks you in advance.

Here is the code I load image from Library folder of my app.
self.imageView.image = [UIImage imageWithContentsOfFile:self.photoGraph.imageFileName];

We have package data to be downloaded from the Internet
Extract downloaded data to /Library/Caches/data/

It worked fine from iOS 7 and prior
On iOS8 it has error as image below

For iOS 6 and above I would suugest to use UICollectionView and PSTCollectionView.
The goal is to use PSTCollectionView on iOS 4/5 as a fallback and switch to UICollectionView on iOS6. We even use certain runtime tricks to create UICollectionView at runtime for older versions of iOS. Ideally, you just link the files and everything works on older systems.
Otherwise ,use AQGridView OR ZZGridView
I am creating an app in which I need to copy image from IOS Photo library to the app's Document directory and then upload the file to the server. I'm using the UIImagePickerController to select the image from the Photo library and save it in the app folder. It works good for the "jpeg" and "png" images using UIImageJPEGRepresentation and UIImagePNGRepresentation.
I don't see any option to copy and save the "gif" images in IOS. Is it possible to save the animated gif images. Please throw some light on how to process and save the original images (bmp, jpg, gif, png, tiff, etc.,).
Thanks in advance.
While you can load them (though you need to split them up for animations; Add animated Gif image in Iphone UIImageView - note the convert command near the bottom) one cannot save them.
To save them you'll need to use a third party library.
See this question, How to save a GIF on the iPhone?, and this http://jitsik.com/wordpress/?p=208 library for a solution.
I have iphone application in which I am downloading images from server & displaying it in table cell. I am downloading 10 images at a time. So I am using "PLACEHOLDER" image while image is downloaded from the server. Once image is downloaded , I am replacing placeholder image with actual downloaded image.
My question is , is it ok to use placeholder image ? Does Apple will accept my application with Placeholder image?
Sorry for my bad english.
Any help is appreciated. Thanks.
Yes, apple will accept placholder images. I use them in all my apps when downloading images.
I have an working application which i have tested in my ipod touch. Everything works pretty fine.
My tabbar icons and splash screen images are in a separate folder in my Resources folder
Resources->images
Now, I know for iPhone4 i need to use 2x images.
My question is for support for iPhone4 all that i need to do is add 2x images in my images folder. For example if my splashscreen image is Default.png, I should add my 2x image as Default#2x.png in my images folder and iphone will use it automatically.?
Is it the same for all tabbar images ?
Thanks in advance
Yes, all that you said is correct. Remember to also import the #2x images into your Xcode project (e.g. by dragging them from Finder to Xcode), so they'll be added to the bundle when you build your app.
For the apps I have worked on, I have only one image in this format:
myImage#2x.png
When I reference this image, I make the following call and it always works, whether on a 3GS/iPhone 4 or iPad.
[UIImage imageNamed:#"myImage.png"]
I have created a UIImageView in Interface Builder. When I run the application on the simulator the image shows up, when I run the application on the device the image doesn't show up. Any help is welcome. Thank you!!!
Check your image format, sometimes the image format may not be supported by the device.
Just found out the problem...Thank for the help. The issue was I copied the image from the internet and saved it with a .png file extension without converting it. Then I brought the image into xcode. After I used gimp to convert my image to a .png and replaced it inside xcode it worked properly.
