A general question regarding images to be used in iPhone

This is my first iPhone application. So I have this long list of doubts :-)

My application has a UItableView on the first tab and a Contact us page on the third tab. In both these tabs I display images.

For the UITableView i get images from the server and for the contact us page I have a set of static images of my client.

My question is, is there any specification开发者_JS百科s on the quality of these images that I should follow to get my App approved in Appstore?? These images are readable, but not of high resolution.

I know there are guidelines on the Tabbar icon images, the splash screen images. But what about the static images and the images i receive from the server?

Guidance or help would be appreciated :)

There are specifications based on display. However it is not mandatory to support both the displays (normal and retina).

You may want to dig more into the HIG. If you don't have images of double resolution then on the retina display the appearance of the app may be bad.

However you can use any image(barring other violation like DRM, copyrights etc) in your app. Approval is also based on a large number of parameters. The images may not be a part of it.However they will specify it explicitly if rejected.

Have fun.

If you feel the image is good then use it.. Apple wont gonna reject your app due to images. But just keep in mind that there are few icons defined by apple for specific purpose like action icon for opening actionsheet, camera icon for opening camera console or wallpaper.

Just keep in mind that you are not changing the behaviour of the predefined icons.... Rest all is fine..

Happy iCoding...
