I have implemented a login item as I was recommended in this post. In the helper app I launch the main app using NSWorkspace method launchApplication:showIcon:autolaunch:, sending YES to autolaunch parameter.
The problem is in following: I need to check if the applications was autolaunched not to show start tooltip. The only variant I found is [[NSUserDefaults standardUserDefaults] boolForKey:#"autolaunch"], and it returns NO always.
The problem could be solved using launch arguments - but sandbox, unfortunately, cuts them too.
Is there something I missed?
I use the following code to hide the launched application:
[[NSWorkspace sharedWorkspace] launchApplicationAtURL:[NSURL fileURLWithPath:appPath] options:NSWorkspaceLaunchAndHide configuration:nil error:nil];
If you want to set additional parameters, you can give the method a custom configuration dictionary.
If you have the launcher inside the application bundle:
NSString *appPath=[[[[[[NSBundle mainBundle] bundlePath] stringByDeletingLastPathComponent] stringByDeletingLastPathComponent] stringByDeletingLastPathComponent] stringByAppendingPathComponent:#"MacOS/myApp"];

I have been playing around with NSWorkspace.
[[NSWorkspace sharedWorkspace] launchApplication:#"Photos"] works
[[NSWorkspace sharedWorkspace] launchApplication:#"Contacts"] does not work
[[NSWorkspace sharedWorkspace] launchApplication:#"/Applications/Contacts.app"] works
(Mac OS Sierra)
So, I was wondering if there is any safe way to find the "real" application path. Maybe the Contacts app has different names in different localization of the System ? Why is just "Photos" working fine ?
I would imagine that there should be a way, from an Apple documented application identifier to get the application path, but I found nothing.
Remember that launchApplication: returns a BOOL if it succeeded or not.
To be really certain of the app you are launching, you can also try looking it up via NSWorkspace's URLForApplicationWithBundleIdentifier: API, into which you can plug Contact's application ID of com.apple.AddressBook.
With the result, you can call the explicit location of the app via:
- (NSRunningApplication *)launchApplicationAtURL:(NSURL *)url
options:(NSWorkspaceLaunchOptions)options
configuration:(NSDictionary<NSString *,id> *)configuration
error:(NSError * _Nullable *)error;
The best way to open an app is from file url path. I have did the same for my application like below:
NSString *appPathIs = Url.path;
I take url path in one string and then open it with as you have indicated
[[NSWorkspace sharedWorkspace] launchApplication:appPathIs];
I have tried every way to achieve the same but sometime they work and sometime not. If you want to try another one then please consider this:
NSString *appPathIs = [[NSWorkspace sharedWorkspace] fullPathForApplication:appName];
NSString *identifier = [[NSBundle bundleWithPath:appPathIs] bundleIdentifier];
NSString *path = [[NSWorkspace sharedWorkspace] absolutePathForAppBundleWithIdentifier:identifier];
[[NSWorkspace sharedWorkspace] launchApplication:appPathIs];
I'm developing a Cocoa App and I noticed NSBundle loadNibNamed is deprecated.
I'm trying to use a Sheet to show some config options. I'm using an AppController and the Config Sheet is a NIB created separately.
This is my code.
- (IBAction)showConfig:(id)sender{
if (!_config) {
[NSBundle loadNibNamed:#"Config" owner:self];
}
[NSApp beginSheet:self.config modalForWindow:[[NSApp delegate] window] modalDelegate:self didEndSelector:NULL contextInfo:NULL];
}
Using that code, the config Sheet opens and closes perfectly.
When I switch this [NSBundle loadNibNamed:#"Config" owner:self]; to [[NSBundle mainBundle] loadNibNamed:#"Config" owner:self topLevelObjects:nil]; the config Sheet still works fine.
My real problem is when I want to close it. The app crashes throwing this error:
Thread 1:EXC_BAD_ACCESS (code=EXC_I386_GPFLT)
This is my IBAction to close the config Sheet.
- (IBAction)closeConfig:(id)sender{
[NSApp endSheet:self.config];
[self.config close];
self.config = nil;
}
Once I skip the deprecated line, what do I need to do to close the config sheet correctly?
I'm running Yosemite and Xcode 6.4.
Is the window property in your app delegate class weak? If so, see this answer. The not-deprecated method that you are now using requires your controller to have strong references to the top level objects.
I tried the below code, it is working fine for me. Also am able to launch the mail application as well.
//Note the below path is coming from bundle identifier of Mail APP
NSString *path=#"/Applications/Mail.app"
NSURL *mailURL = [NSURL URLWithString:path];
NSError *err=nil;
[[NSWorkspace sharedWorkspace] launchApplicationAtURL:mailURL
options:NSWorkspaceLaunchDefault
configuration: someData
error:&err];
But it throws me the below error message on console, What it means actually. How to resolve the below issue.
CFURLCopyResourcePropertyForKey failed because it was passed this URL which has no scheme: /Applications/Mail.app
The error is thrown because you are not creating a valid URL. The URL needs a scheme, in your case it is file: so the correct URL is file:///Applications/Mail. You need to create a file URL which works as follows:
NSString *path=#"/Applications/Mail.app";
NSURL *mailURL = [NSURL fileURLWithPath:path];
Note that your code breaks if the user ha moved Mail.app to another location. Also note that if the user doesn't use Apple's Mail app, it won't work well for the user either.
One possibility of doing it a more correct way is given here: How to launch New Message window in Mail.app from my application
Another option is to get the URL for Mail.app in a more fleixble way covering for users that have moved Mail.app. The idea is to use the bundle identifier and then ask NSWorkspace to launch this application by using
- (BOOL)launchAppWithBundleIdentifier:(NSString *)bundleIdentifier
options:(NSWorkspaceLaunchOptions)options
additionalEventParamDescriptor:(NSAppleEventDescriptor *)descriptor
launchIdentifier:(NSNumber **)identifier
(see also in detail here http://theocacao.com/document.page/183).
I created an app which is launched from a custom url in any OSX browser. This worked just fine by adding a standard CFBundleURLName entry to the app's plist.
My application works by reading by parsing some of the parameters on the custom url and then reacting to them.
So for example with a custom url of:
foobar://param1/param2/param3
When clicking on the above url in a browser, OSX would launch my app and pass the actual custom url itself as the first argument to the app. Therefore in the app I could read the first arg and get the url the opened the app, and parse it for params I need.
This works fine in OSX 10.5-10.8, but in 10.9 Mavericks it appears to work slightly differently. Namely that if the application is not already running, it still launches the app but does not pass the custom url as first argument - so the app thinks it's just been launched manually by the user (such as selecting it from launchpad) rather than directly from a browser.
Weirdly, if the application is already open, then clicking the custom url DOES send the url string over to the app as first argument and functionality within the app occurs as expected.
I've tested this across 10.6->10.9 with new and old versions of my app and all exhibit the same behaviour. All work fine on first launch with versions before 10.9 Mavericks, but in 10.9 they don't get the url passed as first arg but then work on 2nd click once already running.
If anyone could shed some light on this I would be very grateful.
Where do you set up your URL handler? It needs to happen early. If you currently have it in applicationDidFinishLaunching, try to move it to applicationWillFinishLaunching.
The following works for me and logs the URL at launch even when the app is not running before I open the URL in Safari, for example. When I change WillFinishLaunching to DidFinishLaunching, I see exactly the behavior you describe.
#implementation AppDelegate
- (void)applicationWillFinishLaunching:(NSNotification *)notification
{
NSAppleEventManager *appleEventManager = [NSAppleEventManager sharedAppleEventManager];
[appleEventManager setEventHandler:self andSelector:#selector(handleGetURLEvent:withReplyEvent:) forEventClass:kInternetEventClass andEventID:kAEGetURL];
}
- (void)handleGetURLEvent:(NSAppleEventDescriptor *)event withReplyEvent:(NSAppleEventDescriptor *)replyEvent
{
NSAppleEventDescriptor *obj = [event descriptorForKeyword:keyDirectObject];
DescType type = [obj descriptorType];
if (type == typeChar) {
NSData *data = [obj data];
if (data) {
NSString *urlString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString:urlString];
NSLog(#"url: %#", url);
}
}
}
#end
reading Adium code today, found an interesting usage of NSURL:
NSURL *baseURL = [NSURL URLWithString:[NSString stringWithFormat:#"adium://%#/adium", [messageStyle.bundle bundleIdentifier]]];
[[webView mainFrame] loadHTMLString:[messageStyle baseTemplateForChat:chat] baseURL:baseURL];
I tried to log the url and got this adium://im.adium.Smooth Operator.style/adium, Then I created a blank project to see how to create such an NSURL but failed. When I sending loadHTMLString message to a webview's frame in my project, if the baseURL is nil, everything is fine, if not, I got a blank page in the view.
here is my code, the project name is webkit
NSURL *baseURL = [NSURL URLWithString:#"webkit://resource"];
//if baseURL is nil or [[NSBundle mainBundle] bundleURL], everything is fine
[[webView mainFrame] loadHTMLString:#"<html><head></head><body><div>helloworld</div></body></html>"
baseURL: baseURL];
[frameView setDocumentView:webView];
[[frameView documentView] setFrame:[frameView visibleRect]];
the question is how to make a self defined protocol instead of http://?
adium://%#/adium , first section is called protocol you can also register your protocol webkit: Take a look at How to map a custom protocol to an application on the Mac? and Launch Scripts from Webpage Links
[NSURLProtocol registerClass:[AIAdiumURLProtocol class]];
[ESWebView registerURLSchemeAsLocal:#"adium"];
I tried to find where did adium define the adium schema in the info.plist, unfortunately, there's nothing there, only some irc/xmpp protocols.
so I finally launched the debugger, and found the code above in the AIWebKitDelegate init method, anyway this is another way to register a self defined protocol~
