In the development of the iphone, it is often necessary to encode the data Base64.

In some large projects, it is necessary to Base64 encode the data encrypted by the RSA encryption algorithm,

The iphone data is then routed over the network to the server side,

The server side receives the data and then decodes it, then processes the decoded data.

1. Interface definition

@interface NSData (BASE64)

+ (NSData *) datafrombase64string: (NSString *) astring;

-(NSString *) base64encodedstring: (Nsinteger) Separatelines;

2. Coding

NSData *stringdata = [ self datausingencoding:nsutf8stringencoding];

nsstring *encodedstring = [StringData base64encodedstring:0];

3. Decoding

nsdata *data = [nsdata datafrombase64string: base64binary];
