Prior to upgrading to xcode 4.6.3 the following code worked perfectly. Now it does NOT. I get a blank white page. This code is placed after super viewDidLoad:
NSString *path = [[NSBundle mainBundle]pathForResource:#"info.rtfd" ofType:#"zip"];
NSURL *url = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];
[webView setScalesPageToFit:YES];

My code must update web view and download web site. But it doesn't because URLWithString returns null. How can I solve this problem? stringByAddingPercentEscapesUsingEncoding is already deprecated.
-(void) setWebViewMain:(NSString *) link {
// link = #"http://www.rbc.ru/society/05/09/2017/59ae2dfe9a794753f05e3e06"; if this string uncomment code is working
NSURL *url = [NSURL URLWithString: link];
NSLog(#"%#",url); // here url is (null)
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:requestObj];
[self.webView reload];
}
try as
-(void) setWebViewMain:(NSString *) link {
// link = #"http://www.rbc.ru/society/05/09/2017/59ae2dfe9a794753f05e3e06"; if this string uncomment code is working
NSURL *url = [NSURL URLWithString: [NSString stringWithFormat:#"%#",link]];
NSLog(#"%#",url); // here url is (null)
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:requestObj];
// [self.webView reload];
}
Just remove the last line from your method and it will work:
-(void) setWebViewMain:(NSString *) link {
// link = #"http://www.rbc.ru/society/05/09/2017/59ae2dfe9a794753f05e3e06"; if this string uncomment code is working
NSURL *url = [NSURL URLWithString: link];
NSLog(#"%#",url); // here url is (null)
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:requestObj];
//[self.webView reload];
}
You can call it like this:
[self setWebViewMain:#"http://www.rbc.ru/society/05/09/2017/59ae2dfe9a794753f05e3e06"];
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];
}
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.
Hello every one this is my simple code.. what i am missing ? it is two days i am trying to sort out the problem.. any idea?
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *path = [[NSBundle mainBundle] pathForResource:#"dog" ofType:#"pdf"];
NSURL *url = [NSURL fileURLWithPath:path];
NSURL *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request]; <<<<<< HERE WHERE THE ERROR COME OUT <<<<<<
[webView setScalesPageToFit:YES];
}
loadRequest argument is of type NSURLRequest and not NSURL as in your case.
And are you sure this line is compiling ?? :
NSURL *request = [NSURLRequest requestWithURL:url];
As far as I know the method returns object of type NSURLRequest and not NSURL
I don't understand why if I load the content of a UIWebView in XCode this way:
NSString *string = #"http://www.dummyurl.org/dummy.pdf";
NSURL *url = [NSURL URLWithString:string];
[my_view loadRequest:[NSURLRequest requestWithURL:url]];
everything works fine, but if a build the original string from a php script I wrote:
NSString *strURL = [NSSTring stringWithFormat:#"www.myserver.php"];
NSString *string = [[NSString alloc] initWithContentsOfURL:[NSURL URLWithString:strURL]];
NSURL *url = [NSURL URLWithString:string];
[my_view loadRequest:[NSURLRequest requestWithURL:url]];
nothing works. I checked my script and it returns EXACTLY the original string (http://www.dummyurl.org/dummy.pdf) that works fine with the first method.
I build from a PHP script the content of a UITextView too, but that works fine.
I don't understand why this method works with the UITextView but not with the UIWebView to load the .pdf.
It may be useful
NSCharacterSet *characterSet = [NSCharacterSet whitespaceAndNewlineCharacterSet];
NSString *tempString = [string stringByTrimmingCharactersInSet:characterSet];
NSURL *url = [NSURL URLWithString:string];
[my_view loadRequest:[NSURLRequest requestWithURL:url]];
Make sure you linked the webview (IBOutlet) and the delegate.
With this lines it should load a url:
webView.delegate = self;
NSURLRequest *urlRequest;
NSString *urlToOpen = [NSString stringWithFormat:#"http://www.stackoverflow.com"];
urlRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:urlToOpen]];
[self.webView loadRequest:urlRequest];
Hope this helps...
I had this and it was a cache problem:
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:url] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60.0]];
