added support for UIActivityIndicatorView while the image is
downloaded, without adding extra ‘setImageWithUrl’ methods to the
UIImageView+WebCache category.
I used [this pull
request](https://github.com/mythodeia/UIActivityIndicator-for-SDWebImage
), original author is [JJSaccolo](https://github.com/JJSaccolo), and
modded it a bit to support loading indicator while the image is
downloading.
the usage is basically this right before the usual sd_setImage...
methods:
```
// show activity indicator
[cell.imageView setShowActivityIndicatorView:YES];
// choose indicator style
[cell.imageView
setIndicatorStyle:UIActivityIndicatorViewStyleGray];
```
- added `username` and `password` properties on `SDWebImageDownloader`
- added `shouldUseCredentialStorage` and `credential` properties on `SDWebImageDownloaderOperation`
- `SDWebImageDownloaderOperation` conforms to `NSURLConnectionDataDelegate` (it used to implement the methods, but didn't stated the protocol in the declaration)
- removed deprecated methods: `- connection:canAuthenticateAgainstProtectionSpace:` and `- connection:didReceiveAuthenticationChallenge:` with `- connectionShouldUseCredentialStorage:` and `- connection:willSendRequestForAuthenticationChallenge:`
- updated demo project to download one image the requires HTTP auth
This is particularly useful if you are bundling images with your app that have been cached by SDWebImage. (ie. if you are 'seeding' your app with a core-data file that contains a lot of URL's to images and would like to also seed those images without having to copy every one of them over)
For example, you can tell SDImageCache to add '[[NSBundle mainBundle] resourcePath]' as a custom path, so that the main bundle will be queried for cached images.
This prevents the need for you to copy pre-cached images over to the caches/ImageCache folder that SDImageCache normally checks for.
The custom paths are read-only.
