How to convert data to image in iphone

Question

I converted an image to data in iphone using

NSData *imageData = UIImagePNGRepresentation(your_image_here);

After that i transferred it to another iphone using bluetooth. Now i need to convert the data back to image. Can any one tell me how to do it.

Answer 1

Just call imageWithData: or on instantiation, you can call initWithData:

Answer 2

[UIImage imageWithData:(NSData *)data];

Answer 3

I assume this is to et back the data which you encoded in the previous question. For converting uiimage to nsdata,

NSData* pictureData = UIImagePNGRepresentation(image);

To get it back,

UIImage *image = [[UIImage alloc]initWithData:pictureData];

Remember to add [image release] at the end.

or you can use

UIImage *image = [[UIImage alloc]init;
[image imageWithData:pictureData];
