add an option for base64 image

[sandcforge]

Hi Xu,
Good contribution to cordova wechat plugin. I have used this great plugin in my meteor apps. It works gracefully.
One suggestion: current URL only supports remote webpage url or local file based url. I am wondering whether there is an possibility to add an option for the base64 image in 'getNSDataFromURL'

This small piece of code work well if I provide a base64 image by url

• (NSData *)getNSDataFromURL:(NSString *)url
  {
  NSData *data = nil;

  if ([url hasPrefix:@"http://"] || [url hasPrefix:@"https://"])
  {
  data = [NSData dataWithContentsOfURL:[NSURL URLWithString:url]];
  }
  /* Added code_/
  else if ([url hasPrefix:@"data:image"]) {
  // a base 64 string
  NSURL *actualURL = [NSURL URLWithString:url];
  data = [NSData dataWithContentsOfURL:actualURL];
  }
  /_end of added code */
  else
  {
  // local file
  url = [[NSBundle mainBundle] pathForResource:[url stringByDeletingPathExtension] ofType:[url pathExtension]];
  data = [NSData dataWithContentsOfFile:url];
  }

  return data;
  }

Thanks,
Chen

Thanks, @sandcforge .

I tested it on my phone, and it didn't work. Maybe you can send a pull request with your code.
