POiOS- Pull HTML id to display an image in an UIImageView
text
Body
copied!<p>I need to be able to pull the line of HTML below from my website and display the image in the imageView I have in my Storyboard. I already Have some code on how to pull text from the same website, could I use something like the other piece of code? Of course, without the striped part, that is only to get plain text. I would just load the link to the image, but the image changes depending on the song playing. I want to try and avoid just displaying the image in a UIWebView, I would much rather prefer displaying it in a UIImageView</p> <p>HTML code:</p> <pre><code><div id="album_cover"> <img height="160px" width="160px" id="imgcover" src="Link to image changed based on the song playing" alt="Loading..."></div> </code></pre> <p>Objective C code:</p> <pre><code>-(void)viewDidLoad { self.urlForLink = @"http://cloudrad.io/pointzeroradio/player"; NSURL *myURL = [NSURL URLWithString: [self.urlForLink stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]]; NSURLRequest *request = [NSURLRequest requestWithURL:myURL]; [webViewForRecents loadRequest:request]; timer = [NSTimer scheduledTimerWithTimeInterval:0.01 target:self selector:@selector(recentTracksText) userInfo:nil repeats:YES]; } -(void)recentTracksText { NSString *textForBlog = [webViewForRecents stringByEvaluatingJavaScriptFromString:@"document.getElementById('current_song').textContent;"]; // Add this step for stripping the HTML from the text you received self.strippedTextForBlog = [self stringByStrippingHTMLFromString:textForBlog]; continuousLabel.text = self.strippedTextForBlog; } </code></pre> <p>Based off of elio.d answer. This works great for me and loads anywhere from 30 seconds to 3 minutes. If anyone has a way that will load quickly.</p> <pre><code>-(void)getImageCover { NSString * js = @"document.getElementById('imgcover').src;"; NSString * imgLink = [webViewForRecents stringByEvaluatingJavaScriptFromString:js]; NSURL * imgURL = [NSURL URLWithString:imgLink]; dispatch_queue_t exampleQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0); dispatch_async(exampleQueue, ^{ NSData * imgData = [NSData dataWithContentsOfURL:imgURL]; UIImage * image = [UIImage imageWithData:imgData]; dispatch_queue_t queue = dispatch_get_main_queue(); dispatch_async(queue, ^{ [imageView setImage:image]; }); }); } </code></pre>
