I am trying to load UIImage object from NSData, and the sample code was to NSImage, I guess they should be the same. But just now loading the image, I am wondering what's the best to troubleshoot the UIImage loading NSData issue.

UIImage contains the data for an image. UIImageView is a custom view meant to display the UIImage .
This is most compatibile way of doing it: UIImage* u =[UIImage imageNamed:@"image. png"]; CIImage* ciimage = [[CIImage alloc] initWithCGImage:u. CGImage];
I didn't try UIImageJPEGRepresentation() before, but UIImagePNGRepresentation works fine for me, and conversion between NSData and UIImage is dead simple:
NSData *imageData = UIImagePNGRepresentation(image); UIImage *image=[UIImage imageWithData:imageData]; UIImage has an -initWithData: method. From the docs: "The data in the data parameter must be formatted to match the file format of one of the system’s supported image types."
