NSData and UIImage

NSData and UIImage

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.

How do you get the number keypad to come up in an iPhone web app?


How do I show the keyboard by default in UITextView?
UIImage has an -initWithData: method. C++ library integration to iPhone applicationFrom the docs: "The data in the data parameter need be formatted to match the file format of one of the system’s supported image types.". Managing multiple asynchronous NSURLConnection connections

I didn't try UIImageJPEGRepresentation() before, although UIImagePNGRepresentation works fine for me, and conversion between NSData and UIImage is dead simple:. get viewport position in javascript in iphone safari
NSData *imageData = UIImagePNGRepresentation(image); UIImage *image=[UIImage imageWithData:imageData]; 


Try this to convert an image to NSdata:.
UIImage *img = [UIImage imageNamed:@"image.png"]; NSData *data1 = UIImagePNGRepresentation(img); 


theData should be a NSData object which already contains the data. You need to did the file loading/downloading to the NSData object before it is used. You must inspect it by using NSLog on theData and see if it contains the valid data..
