How to convert data to image in iOS

Question

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

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];
