UIImage图片转成base64字符串:
UIImage *_originImage = [UIImage imageNamed:@"full_playlist_hl.png"];
NSData *_data = UIImageJPEGRepresentation(_image, 1.0f);
NSString *_encodedImageStr = [_data base64Encoding];
NSLog(@"===Encoded image:\n%@", _encodedImageStr);
Base64字符串转UIImage图片:
NSData *_decodedImageData = [[NSData alloc] initWithBase64Encoding:_encodedImageStr];
UIImage *_decodedImage = [UIImage imageWithData:_decodedImageData];
NSLog(@"===Decoded image size: %@", NSStringFromCGSize(_decodedImage.size));
