Base64转码

NSData* originData = [originStr dataUsingEncoding:NSASCIIStringEncoding];

NSString* encodeResult = [originData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];

NSLog(@"encodeResult:%@",encodeResult);

NSData* decodeData = [[NSData alloc] initWithBase64EncodedString:encodeResult options:0];

NSString* decodeStr = [[NSString alloc] initWithData:decodeData encoding:NSASCIIStringEncoding];

iOS 使用开源库 GTMBase64 转码

 

/**

*GTM 转码

*/

-(void)GTMEncodeTest

{

NSString* originStr = @"Man";

NSString* encodeResult = nil;

NSData* originData = [originStr dataUsingEncoding:NSUTF8StringEncoding];

NSData* encodeData = [GTMBase64 encodeData:originData];

encodeResult = [[NSString alloc] initWithData:encodeData encoding:NSUTF8StringEncoding];

NSLog(@"%@",encodeResult);

}

/**

* GTM 解码

*/

-(void)GMTDecodeTest

{

NSString* encodeStr = @"TWFu";

NSString* decodeResult = nil;

NSData* encodeData = [encodeStr dataUsingEncoding:NSUTF8StringEncoding];

NSData* decodeData = [GTMBase64 decodeData:encodeData];

decodeResult = [[NSString alloc] initWithData:decodeData encoding:NSUTF8StringEncoding];

NSLog(@"%@",decodeResult);

}
