[wode211]

Hi guys,

I need to save images from UIWebview to my app's document folder, the image format may be jpg, gif, png or others. I have two questions,
1: How to detect whether I select a image or don't, and which image is selected.
2:How to save image to the document folder.

anyone can guide me ?
Thank you !

Are you using the UIWebView to kust one image?
Which means that you know the URL of that image.

Them you should just download the image via NSURLRequest and save the data, after which you can just display the image in a normal UIImageView.
There a lot tutorials on how to do this, just search for async imageview.

If you want the user to be able to select an image displayed in the webview where there are multiple images. Then you should look at some kind of Javascript method and create a custom URL schema, which you can then pick-up from you code.
Then just the method above to download.

1. make a text field to obtain url of image . You can get the url through this piece of code

- (void)webViewDidStartLoadUIWebView *)webView
{
url1 = [webView.request URL];
urlField.text = [url absoluteString];
}
2. make proper connection of delegate of UIWebView in file's owner.
3. make button to download the image!! and method in which u can write!!




url = [webView.request URL];
NSLog(@"url recieved: %@", url);
NSLog(@"Downloading...");
// Get an image from the URL below
UIImage *image = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:url]];
//UIImage *image = [[UIImage alloc] init];
NSLog(@"%f,%f",image.size.width,image.size.height) ;
// Let's save the file into Document folder.
// You can also change this to your desktop for testing. (e.g. /Users/kiichi/Desktop/)
NSString *deskTopDir = @"/Users/gauravmurghai/Desktop";
//NSString *docDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDire ctory, NSUserDomainMask, YES) objectAtIndex:0];
// If you go to the folder below, you will find those pictures
NSLog(@"%@",deskTopDir);
NSLog(@"saving png");
NSString *pngFilePath = [NSString stringWithFormat:@"%@/jpg.png",deskTopDir];
NSData *data1 = [NSData dataWithData:UIImagePNGRepresentation(image)];
[data1 writeToFilengFilePath atomically:YES];
NSLog(@"saving jpeg");
NSString *jpegFilePath = [NSString stringWithFormat:@"%@/jpg.jpeg",deskTopDir];
NSData *data2 = [NSData dataWithData:UIImageJPEGRepresentation(image, 1.0f)];
[data2 writeToFile:jpegFilePath atomically:YES];
NSLog(@"saving image done");
[image release];
