问题描述
无论如何都要在iphone照片存储的UIWebview中显示图像
Is there anyway to display a image in a UIWebview from the iphone photo storage
推荐答案
可能这是合适的代码在上传图片中，
May be this is the suitable code in the upload image,
- (BOOL)webView:(UIWebView*)webViewRef shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType {
//we are listening out for links being click
if (navigationType == UIWebViewNavigationTypeLinkClicked)
{
NSURL *URL = [request URL]; //Get the URL
if ( [[URL scheme] isEqualToString:@"objc"] ) {
webView = webViewRef;
SEL method = NSSelectorFromString( [URL host] );
if ([self respondsToSelector:method])
{
[self performSelector:method withObject:nil afterDelay:0.1f];
}
return NO;
}
}
return YES;
}
-(void)takePicture
{
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.delegate = self;
id delegate = [[UIApplication sharedApplication] delegate];
[[delegate viewController] presentModalViewController:imagePicker animated:YES];
[imagePicker release];
}
#pragma mark - Image Picker
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
NSData *flatImage = UIImageJPEGRepresentation(image, 0.1f);
NSString *image64 = [flatImage base64EncodedString];
NSString *js = [NSString stringWithFormat: @"processImage('data:image/jpeg;base64,%@')", image64];
[webView stringByEvaluatingJavaScriptFromString:js];
[picker dismissModalViewControllerAnimated:YES];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissModalViewControllerAnimated:YES];
}
