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));

//图片转字符串-(NSString *)UIImageToBase64Str:(UIImage *) image{    NSData *data = UIImageJPEGRepresentation(image, 1.0f);    NSString *encodedImageStr = [data base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];    return encodedImageStr;}//字符串转图片-(UIImage *)Base64StrToUIImage:(NSString *)_encodedImageStr{    NSData *_decodedImageData   = [[NSData alloc] initWithBase64Encoding:_encodedImageStr];    UIImage *_decodedImage      = [UIImage imageWithData:_decodedImageData];    return _decodedImage;}
