Question

我的应用程序使用GCDWebServer我从我的iPhone相册中获取照片AssetsLibrary并将其存储在中NSDocumentDirectory.我只想访问此照片的Url以在网页中显示它们.

有我的代码:

[_webServer addHandlerForMethod:@"POST"
                              path:@"/"
                      requestClass:[GCDWebServerURLEncodedFormRequest class]
                      processBlock:^GCDWebServerResponse *(GCDWebServerRequest* request) {

                          ALAsset *asset = [self.arrayPictures objectAtIndex:0];
                          ALAssetRepresentation *rep = [asset defaultRepresentation];
                          CGImageRef iref = [rep fullResolutionImage];
                          UIImage *thumbnail = [UIImage imageWithCGImage:iref];
                          NSString* path ;
                          if (thumbnail != nil)
                          {
                              NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
                              NSString *documentsDirectory = [paths objectAtIndex:0];
                               path =  [[NSString alloc] initWithString:[documentsDirectory stringByAppendingPathComponent:@"test.png"]];
                              NSData* data = UIImagePNGRepresentation(thumbnail);
                              [data writeToFile:path atomically:YES];
                          }

                          NSURL *url = [NSURL fileURLWithPath:path];
                          NSString* html = [NSString stringWithFormat:@"<html><body><img src=\"%@\" width=\"400\" height=\"500\"/></body></html>", url];
                          return [GCDWebServerDataResponse responseWithHTML:html];

                      }];

对于DocumentDirectory路径

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *imagePath = [[NSString alloc] initWithString:[documentsDirectory stringByAppendingPathComponent:@"test.jpg"]];
NSURL *baseURL2 = [NSURL fileURLWithPath:documentsDirectory];
NSString* html2 = [NSString stringWithFormat:@"<html><body><img src=\"%@\" width=\"400\" height=\"500\"/></body></html>", imagePath];

[_webView loadHTMLString:html2 baseURL:baseURL2];

对于捆绑的资源

NSString *path = [[NSBundle mainBundle] pathForResource:@"ahsan" ofType:@"jpg"]; // path to your image source.

NSURL *baseURL = [NSURL fileURLWithPath:path];

NSString* html = [NSString stringWithFormat:@"<html><body><img src=\"%@\" width=\"400\" height=\"500\"/></body></html>", path];
