iPad Launch Image Orientations

iPad Launch Image Orientations

To deal with various orientation options, a new naming convention has been created for iPad launch images. The screen size of the iPad is 768×1024, notice in the dimensions that follow the height takes into account a 20 pixel status bar.

Filename Dimensions
Default-Portrait.png * 768w x 1004h
Default-PortraitUpsideDown.png 768w x 1004h
Default-Landscape.png ** 1024w x 748h
Default-LandscapeLeft.png 1024w x 748h
Default-LandscapeRight.png 1024w x 748h
Default.png Not recommended

• If you have not specified a Default-PortraitUpsideDown.png file, this file will take precedence.

** If you have not specified a Default-LandscapeLet.png or Default-LandscapeRight.png image file, this file will take precedence.

Void Pinter Meaning

Void Pinter Meaning :

void * p; 

The name of the blog comes from the world of software development. In the C, C++, and C# programming languages (and perhaps others), a void pointer is a variable containing an address in memory. The above line of code declares a void pointer named "p" that has not yet been set to an address. What is stored at the address is left unspecified and usually the void pointer is converted to be a pointer to a specific type (cast) before it is used. This construct gives the developer quite a bit of power, but as Uncle Ben said, "with great power, comes great responsibility". The developer can very easily shoot themselves in the foot with a void pointer, but when used carefully and in the right circumstances, one can accomplish wonderful things.

iPhone MapKit Framework to cache Google map for offline: Good Idea

1) Can MapKit Framework support caching Google Map on iPhone locally ? 
2) Can MapKit Framework support to use offline map during GPS-ing ?


Answer :
Unfortunately no, you cannot cache the google tiles (at least not in iOS 4.x). However, you can use an MKOverlay to create an overlay that displays and caches tiles from another map source like OpenStreetMap. Apple published an example TileMap overlay with their 2010 WWDC videos.


Reference link:
http://stackoverflow.com/questions/3792532/iphone-mapkit-framework-to-cache-google-map-for-offline-use


Q. I am working on GPS Track...but when my device is offline then not show the Map. Can you please help for shut out it ? or How to implement the tiles in my application ?
Answer preferred by Apple forum.
Answer 1. : As I understand it MapKit terms and conditions require Google, try route-me for an alternative framwork.


Answer 2. : MapKit maintains a fixed-size map tile cache that contains (roughly speaking) tiles for the most recently viewed areas.  If the device is offline, and your MKMapView is zoomed to an area for which there are no tiles in the tile cache, maps will not be available.

The only solution to this would be to bundle your own map tiles with your app and implement your own map view.  It's up to you to decide if that is worthwhile for your use case.
