In my cocoa app I want to hide all applications I've found this but I don't want to do in that way. so, is there any way to get result as expected. Below code which I am using and problem is finder windows not closing.
for (NSRunningApplication *app in [[NSWorkspace sharedWorkspace] runningApplications]) {
[app hide];
}
I guess you're looking for [[NSWorkspace sharedWorkspace] hideOtherApplications]; call.

I have a Mac app with a preferences window. The preferences window is opened modally
-(IBAction)displayPreferencesWindow:(id)sender{
if (!pc) {
pc = [[PreferencesController alloc] initWithWindowNibName:#"PreferencesController"];
pc.delegate = self;
}
NSWindow *pcWindow = [pc window];
[NSApp runModalForWindow: pcWindow];
[NSApp endSheet: pcWindow];
[pcWindow orderOut: self];
}
In the preferences Window I have a button that opens the account preferences panel
- (IBAction)openSystemPrefs:(id)sender {
[[NSWorkspace sharedWorkspace] openFile:#"/System/Library/PreferencePanes/Accounts.prefPane"];
}
The problem is that the account preferences panel does not open in front of the actual Window. How can I achieve this?
This is kind of weird, and goes against the comments in the header, but try using this instead:
- (BOOL)openFile:(NSString *)fullPath withApplication:(NSString *)appName andDeactivate:(BOOL)flag;
From the comments there:
Open a file at some path. If you use the variant without the
withApplication: parameter, or if you pass nil for this parameter, the
default application is used. The appName parameter may be a full path
to an application, or just the application's name, with or without the
.app extension. If you pass YES for andDeactivate:, or call a variant
without this parameter, the calling app is deactivated before the new
app is launched, so that the new app may come to the foreground unless
the user switches to another application in the interim. Passing YES
for andDeactivate: is generally recommended.
So it sounds like your app should be deactivating (since you're calling a variant without the andDeactivate: parameter) but I would try explicitly using the variant with that parameter, just to be sure.
Empirically, it appears that the launched application will not activate if the launching application is presenting modal UI, at least not when using the NSWorkspace API. I was able to hack something up using AppleScript that appears to achieve the desired results:
- (IBAction)doStuff:(id)sender
{
[[NSWorkspace sharedWorkspace] openFile:#"/System/Library/PreferencePanes/Accounts.prefPane"];
dispatch_async(dispatch_get_global_queue(0, 0), ^{
NSString* s = #"tell application \"System Preferences\" to activate";
NSAppleScript* as = [[[NSAppleScript alloc] initWithSource: s] autorelease];
NSDictionary* error = nil;
if ([as compileAndReturnError: &error])
{
(void)[as executeAndReturnError: &error];
}
});
}
I dispatched it to the background queue because it takes a few hundred milliseconds to compile and run the AppleScript and it's a little conspicuous if done synchronously (the button stays highlighted longer than you expect).
If you were feeling really masochistic, you could probably get the script compiling phase out of it (i.e. quicker) by conjuring up the equivalent AppleEvents and sending them directly, but this appeared to achieve the desired effect, even while presenting modal UI in the launching application.
I have an app with basic alarm functionality. In my applicationWillResignActive: method I have it setup to create notifications to set off the alarm. This works pretty great, and I believe this is the proper way to do it (let me know if you think there is a better way).
Only in the specific situation, ONLY ON iOS 6, when the application is not "quit" (the home button is never pressed) but the user merely locks the phone or the phone auto locks, the notifications don't go off.
I have traced through the code, and the notifications are indeed being created and it worked perfectly in iOS 5.
Here is my code:
- (void)applicationWillResignActive:(UIApplication *)application
{
[UIApplication sharedApplication].idleTimerDisabled = NO;
[alarm setupForBackground];
if ([alarm isRunning]) {
[alarm stop];
}
}
Here is the notification creation method:
- (void)setupForBackground
{
UILocalNotification* alarmNotification = [[UILocalNotification alloc] init];
if (alarmNotification) {
alarmNotification.fireDate = alarmDate;
alarmNotification.timeZone = [NSTimeZone defaultTimeZone];
alarmNotification.repeatInterval = 0;
alarmNotification.soundName = #"NotificationSound.aif";
[[UIApplication sharedApplication] scheduleLocalNotification:alarmNotification];
}
}
I have been searching for an answer for a while, and I could not find anything stating something about notification changes. Thanks for any help.
I have a semi-solution. Apparently if you add an AlertBody to the notification, then it works.
My belief is that this is a bug in iOS 6. As I mentioned it worked in iOS 5, the documentation makes no mention of having such a requirement, and the notification does work without the AlertBody if the application is quit (the home button is pressed).
Still curious to see if my understanding is correct and if I should file a bug report with Apple.
Thoughts anybody?
I just wanted to add some notifications to Gyazo app.
I finally able to send notifications to the notifications center http://korniltsev.ru/p/jz6m3Nm.png
however when i click on it and the app is not launched it launches in some strange way:
it shows empty window(even if i set it visibleAtLaunch to 0) and nothing happens;http://korniltsev.ru/p/jz6mvk0.png
the code i'm trying to use is here:
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
NSUserNotification * clicked = [[aNotification userInfo]
objectForKey:NSApplicationLaunchUserNotificationKey];
if (clicked){
[NSApp terminate:self];
return;
}
...
I send notifications like this
NSUserNotificationCenter *manager = [NSUserNotificationCenter defaultUserNotificationCenter];
NSUserNotification *urlNotification = [[NSUserNotification alloc]init];
[urlNotification setTitle:appName];
[urlNotification setInformativeText:url];
[manager deliverNotification:urlNotification];
What am i doing wrong?
[NSApp terminate:self] has a lot of side effects. Are you sure these side effects are not creating your blank window? Have you tried calling [NSApp terminate:self] immediately in applicationDidFinishLaunching and making sure you application quits cleanly in every case? If it does not you will likely have to look at what you are doing in your application's document controller (if you have one) and applicationShouldTerminate.
I'm trying to open iOS's mail application by clicking a button.
So I did this :
NSString *mailString = [NSString stringWithFormat:#"mailto://test#test.com"];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:mailString]];
But nothing in particular happens... what's the problem ?
Thanks for your advices
#"mailto:test#test.com"
instead of
#"mailto://test#test.com"
Better way of doing this would be to use MFMailComposeViewController
And it works only on the real device, not on the simulator (in my case)
is their any better way to quit the application programmatically?
recently i made a radio application that have a user setup to set a time using NSTimer for quit the app process ( i mean sleep time). when the time reaches the app should be stop its process and quit.
i used these statements to quit the app when time reaches,
[[UIApplication sharedApplication] suspend];
[[UIApplication sharedApplication] terminateWithSuccess];
theTimer=[NSTimer scheduledTimerWithTimeInterval:(1.0/1.0) target:self selector:#selector(countTime) userInfo:nil repeats:YES];
counter-=1;
timeLeft.text=[NSString stringWithFormat:#" %d",counter];
if (counter==0.0) {
[theTimer invalidate];
[[UIApplication sharedApplication] suspend];
[[UIApplication sharedApplication] terminateWithSuccess];
is their any problem by using [[UIApplication sharedApplication] suspend];
[[UIApplication sharedApplication] terminateWithSuccess]; methods
any other better way to quit the app, or at least freeze the app process..
i need help?
Apple will not approve any application that deliberately suspends or terminates itself. You may use only those methods listed in the official documentation, which does not include suspend or terminateWithSuccess.
I've always used exit(0). I suppose that if you have to run code before the app quitting you should call it before exit(0).
Apple discourages the use of exit() because from the user point of view it looks like a crash. But they also say there is no API call to gracefully terminate your app.
If you're looking for a way to terminate your app without the user pressing home, during sleep time, I assume he won't confuse it with a crash, since he won't be paying attention to your app and exit() leaves no crash log.
So, your options are:
Forget this and just beep after some time to remind him to close the app. (terrible!)
Close the app using your private calls and risk Apple's rejection.
Close the app using exit() and stick with POSIX (accepted) calls.
tanq for your replays, so i just forget about quitting my application programatically. next way is to stop playing my MPMoviePlayerController object. got the next level problem
my settings page for sleepTime and music playing pages, both are different viewControllers
so i can't access MPMoviePlayerController object directly in time settings page, so i created a method on music playing page
MPMoviePlayerController *player=[[MPMoviePlayerController alloc]initWithContentURL:[NSURL URLWithString:#"http://www.radioparadise.com/musiclinks/rp_64aac.m3u"]];
[player prepareToPlay];
[player play];
- (IBAction)StopPlay:(id)sender
{
[player stop];
}
so i created an object for music playing page and i called this method from settings page.,
this is my code in settingsPage
#class MusicPlayingPage;
#interface secondView : UIViewController
{
MusicPlayingPage *audio;
}
and called the method in settingsPage
[audio stopPlay];
control reaches correctly to streamingPage, but it seems like player is not stoping play, i can't access any of these player options [player stop]; , [player pause];
any problem for this method in musicPlayingPage
- (IBAction)StopPlay:(id)sender
{
[player stop];
}
sorry if my question is not understandable.
