IOS Base64 transcoding (using the IOS7 system comes with a coded library and GMTBase64 two different ways)

Demo:http://pan.baidu.com/s/1i3lvadz
The system provides a Base64 transcoding method in IOS7

Examples are as follows:

nsdata* origindata = [originstrdatausingencoding:nsasciistringencoding];

nsstring* encoderesult = [Origindatabase64encodedstringwithoptions: Nsdatabase64encodingendlinewithlinefeed];

NSLog (@ "encoderesult:%@", Encoderesult);

nsdata* decodedata = [[nsdataalloc] initwithbase64encodedstring: Encoderesult options:0];

nsstring* decodestr = [[nsstringalloc] initwithdata :d ecodedataencoding:nsasciistringencoding];

IOS uses open Source Library GTMBase64 transcoding

/**

*gtm transcoding

*/

-(void) gtmencodetest

{

nsstring* originstr = @ "man";

nsstring* encoderesult = nil;

nsdata* origindata = [originstrdatausingencoding:nsutf8stringencoding];

nsdata* encodedata = [GTMBase64encodedata: Origindata];

Encoderesult = [[nsstringalloc] initwithdata: Encodedataencoding: nsutf8stringencoding];

NSLog (@ "%@", Encoderesult);

}

/**

* GTM decoding

*/

-(void) gmtdecodetest

{

nsstring* encodestr = @ "Twfu";

nsstring* decoderesult = nil;

nsdata* encodedata = [encodestrdatausingencoding:nsutf8stringencoding];

nsdata* decodedata = [GTMBase64decodedata: Encodedata];

Decoderesult = [[nsstringalloc] initwithdata:d ecodedataencoding: nsutf8stringencoding];

NSLog (@ "%@", Decoderesult);

}
