How to Base64 encoding on the iPhone

Question

How do I do Base64 encoding on the iPhone?

I have found a few examples that looked promising, but could never get any of them to work on the phone.

Answer 1

You can see an example here.

This is for iOS7+.

I copy the code here, just in case:

// Create NSData object NSData *nsdata = [@"iOS Developer Tips encoded in Base64"   dataUsingEncoding:NSUTF8StringEncoding];  // Get NSString from NSData object in Base64 NSString *base64Encoded = [nsdata base64EncodedStringWithOptions:0];  // Print the Base64 encoded string NSLog(@"Encoded: %@", base64Encoded);  // Let's go the other way...  // NSData from the Base64 encoded str NSData *nsdataFromBase64String = [[NSData alloc]   initWithBase64EncodedString:base64Encoded options:0];  // Decoded NSString from the NSData NSString *base64Decoded = [[NSString alloc]    initWithData:nsdataFromBase64String encoding:NSUTF8StringEncoding]; NSLog(@"Decoded: %@", base64Decoded);

Use this library to encode Base64.

It also supports ARC
