When my UIWebView loads my index.html the CSS and JavaScript references show as broken. What is wrong with the code below? (I verified that appUrlString is pointing to the correct directory)
NSString *htmlFile = [[NSBundle mainBundle] pathForResource:#"index" ofType:#"html" inDirectory:#""];
NSData *htmlData = [NSData dataWithContentsOfFile:htmlFile];
NSString *appUrlString = [NSString stringWithFormat:#"%#/web/", [[NSBundle mainBundle] resourcePath]];
NSURL *appUrl = [NSURL URLWithString:appUrlString];
[_appWebView loadData:htmlData MIMEType:#"text/html" textEncodingName:#"UTF-8" baseURL:appUrl];
This is what shows in the simulator.
You should use
NSURL *appUrl = [NSURL fileURLWithPath:appUrlString];
because it's a local filePath. In your version 'appURL' was giving back nil.
So no baseurl got set.

SystemSoundID soundID6; // declaration
NSURL *gamePlayMusic = [NSURL fileURLWithPath:[[NSBundle
mainBundle]pathForResource:#"song1" ofType:#"wav"]];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)Music,&soundID6);
AudioServicesPlaySystemSound(soundID6); //running of music
may I know what to code to run this music again after it finish/complete.
1. Add AVKit.framework.
2.create a global webview object like UIWebView* audioPlayerView;
3.create a button action for playing audio file
4.your mp3 file add in to your bundel.
-(IBAction)playAudioFile:(UIButton*)sender
{
NSString *path = [[NSBundle mainBundle] pathForResource:#"your file name" ofType:#"mp3"];
NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[audioPlayerView loadRequest:request];
[audioPlayerView setScalesPageToFit:YES];
[self.view addSubview:audioPlayerView];
}
Here is my scenario:
I have a folder called "HTML" in my bundle. This folder has an HTML file and 5 images. The HTML file references all the images at some point using a simple img tag.
<img src="tut_navigation.png" />
Now I have a UIWebview which I used to load the HTML file. All of the contents of the HTML file are rendered correctly except for my images. My images are not showing up for some strange reason. Then I did some research and found related posts saying to load URL like so:
NSString *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"tutorial" ofType:#"html" inDirectory:#"HTML"]];
NSString* htmlString = [NSString stringWithContentsOfFile:url encoding:NSUTF8StringEncoding error:nil];
NSString *path = [[NSBundle mainBundle] bundlePath];
NSURL *baseURL = [NSURL fileURLWithPath:path];
[self.webView loadHTMLString:htmlString baseURL:baseURL];
Once I made this change and ran it again, this time only the first image is loading up, the others ones are not. I'm lost as to what the issue is. When I view this HTML file in a web browser, everything is working fine. Any ideas?
The baseURL needs to be the a path to the HTML folder inside the app bundle, not (as you have it) a path to the app bundle itself.
Change this:
NSString *path = [[NSBundle mainBundle] bundlePath];
NSURL *baseURL = [NSURL fileURLWithPath:path];
[self.webView loadHTMLString:htmlString baseURL:baseURL];
To this:
[self.webView loadHTMLString:htmlString baseURL:url];
You had the right URL for the base URL (url) and then you just threw it away and substituted the URL of the bundle itself, which is wrong.
Even better, forget the base URL and just use a URL instead of a path string for the file itself:
NSString *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"tutorial" ofType:#"html" inDirectory:#"HTML"]];
NSURLRequest* req = [[NSURLRequest alloc] initWithURL:url];
[self.webview loadRequest: req];
I am using below code
// it is showing nil for path
NSString *path = [[NSBundle mainBundle] pathForResource:#"filetext.doc" ofType:nil];
NSURL *url1 = [NSURL fileURLWithPath:path];
// it is showing working
NSString *path = [[NSBundle mainBundle] pathForResource:#"filetext.txt" ofType:nil];
NSURL *url1 = [NSURL fileURLWithPath:path];
Please help what is the issue
According to the docs, the method returns nil if the file cannot be found. The conclusion, therefore, is that the file is missing. Check your project's Build Phases/Copy Bundle Resources to ensure that the file is actually present because in all likelihood it is not.
I have the following code in an AppDelegate.m file that opens Google when I open my app. I am trying to change it to open a .HTML web page I copied into my Xcode project but it is not working. I am using Xcode 4.5.2.
The code that works to open Google is:
#implementation MDAppDelegate
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:#"http://www.google.com"]];
[self.webView.mainFrame loadRequest:request];
}
I tried changing it to (so that it would load my test.html file I put in the project folder but the app just comes up blank now). What am I missing?
#implementation MDAppDelegate
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:#"test.html"]];
[self.webView.mainFrame loadRequest:request];
}
As long as your test.html is copied at the root of your project (make sure it's also copied to your final app bundle, huh? - check Build Phases) you can load it up your Web View using this code :
NSString *path = [[NSBundle mainBundle] pathForResource:#"test" ofType:#"html"];
NSURL* fileURL = [NSURL fileURLWithPath:path];
NSURLRequest* request = [NSURLRequest requestWithURL:fileURL];
[self.webView.mainFrame loadRequest:request];
[NSURL URLWithString:#"test.html"] is not creating a valid URL to your file. Try that: (it is from an iOS project, but should apply to OS X apps as well). I'm using loadHTMLString:baseURL: instead of loadRequest:
NSString* fileName = [[NSBundle mainBundle] pathForResource:#"test" ofType:#"html"];
NSString* htmlString = [NSString stringWithContentsOfFile:fileName encoding:NSUTF8StringEncoding error:NULL];
NSURL *baseURL = [[NSBundle mainBundle] bundleURL];
[self.webView loadHTMLString:htmlString baseURL:baseURL];
[NSURL URLWithString:#"test.html"]
There's your problem. Assuming that your test.html file is in the resource folder of your application bundle, do this instead:
[[NSBundle mainBundle] URLForResource:#"test" withExtension:#"html"];
NSBundle has a few other methods for easily creating URLs in case the one above isn't appropriate (like if the file is in a subdirectory). Take a look at the NSBundle reference page for more info.
I have been able to read a file called 'exerciseA.htm' from a live url. but now i need to bring the file locally add it to the project and read it from there. I have dragged the file into xcode to add it. Now i need to read its contents to a string, however the following doesnt seem to work:
NSString* exerciseAPage = [[NSString alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"exerciseA" ofType:#"htm"] encoding:NSUTF8StringEncoding error:&error];
[exerciseWebViewA loadHTMLString:exerciseAPage baseURL:nil];
Is this the correct way to load local htm file to a webview?
I do it the following way (Which is basically the same as you specify):
NSURL *url = [[NSBundle mainBundle] URLForResource:nameOfHtmlFile withExtension:#"html"];
NSError *error;
NSString *contentString = [NSString stringWithContentsOfURL:url encoding:NSStringEncodingConversionAllowLossy error:&error];
NSURL *baseUrl = [NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]];
[self.webView loadHTMLString:contentString baseURL:baseUrl];
Hope this helps
