UIImage from bytes held in NSString

Question

I am trying to create a UIImage from a byte array that is actually held within a NSString.

Can someone please tell me how I can do that?

Here is what I was think

Answer 1

I bet your image data has some null characters in there (0x00) and as you know that is the terminator for the string, so when you ask for the C string, you probably get way-way too little data.

Try something like - (NSData *)dataUsingEncoding:(NSStringEncoding)encoding; to generate your NSData.

If that doesn't work you need to evaluate whether the setting the data into an NSString (with embedded null chars) isn't causing a loss of data too.

Like one of the other respondents, perhaps base-64 encoding your data would be a good idea (if using a string to transport the img data is a requirement)

Good luck.
