For some reason, when I press "Capture" while my device is connected and running the app (launched via Build & Run in Xcode), nothing happens. Never get a screenshot. iPhone OS 3.0. What can be the problem.
I've had this problem—it seems to be caused by there being a screenshot currently selected in the Organizer. Click on the left-hand screenshot pane to highlight it (i.e. deselect whatever screenshot thumbnail is selected), then hit the Capture button.

I start each of three iPad's running my app in each one's own Xcode window, each showing the debug log (NSLog) output for each iPad. So there are three windows showing three iPad's running my app.
When iPad #1 crashes, after a few minutes, my app view disappears and iPad home is shown.
But on Xcode, the window that was showing iPad #1 debug log switches to the debug log of one of the remaining iPad's that are still running.
How can I view the debug NSLog logs for iPad #1 again, so I can see what it was doing when it crashed?
Yes, that was it:
cmd-7
or
View menu > Navigators > Show Log Navigator
then find "Debug" row in the pane on the left, and DOUBLE-CLICK its little right-arrow icon on its left.
I was confused because I single-clicked and it updated the title of the tab of the window to the right but didn't update it. Double-clicking opens a new window with the desired log.
Thanks!
I am building an iphone app.However my app crashes at a point when i run simulator.I want to know the reason.But i don't know how to see crash logs. Please give me some information about how to see crash logs.
in Xcode open the console Window and you will see the crash log.
Use this shortcut to view the console window if it's not already showing:
Debug Area show/hide : ⇧ ⌘ Y
Press the middle button of the view group buttons. It will bring the console and you will see if something happens.
This might seem like a strange question, but can I actually shut down the iPhone and restart it in the iPhone simulator? I want to do this to see if my settings are saved and reloaded when the app is relaunched AFTER shutdown.
Thanks
Yes. Press Command+Q to quit the simulator.
This will close all the apps running in the simulator.
Pressing the home button only returns to the home screen without quitting the apps(ios 4 or later) because of multitasking.
You can also double tap the home button, click and hold on the icons at the bottom of the screen till a red circle appear, and click on the red circle to close the running app.
As of XCode 9, the best way to close a single simulator is using the Cmd + W shortcut, or going to File -> Close Window.
If your'e xcode 9.You can now shutdown the simulator by long-pressing the power button.
To close/shutdown one simulated device without closing other simulations, select the device you want to shut down then go to "File" and choose "Close Window".
On the IPhone, is it possible to get a screenshot of the currently running application, from another application that is running/backgrounded/being launched? or somehow make available a screenshot of the current application to another application that is then automatically launched?
No it is not possible. It is not possible to know anything about another apps in iOS (if you're using documented methods).
This is possible using Xcode's Organizer:
in Xcode, select "Window" menu and then "Organizer"
in the newOrganizer window, select "Devices"
select your iPhone device and unfold
select "Screenshots" at the bottom of the list
now click on the "New screenshot" button (bottom right of the window)
You can export screenshots just by drag/drop on your desktop.
I am testing with iPhone simulator and I want to get the message to allow or not the user location. My problem is that I have clicked once (to test it) the no button with the Do not show this message again checked. How can I get it again?
Thanks for reading.
Now I have the answer to this problem. Into the iOS Simulator, you have to click under the "iOS Simulator" window menu and to choose the "Reset content and settings" options.
