I just recognized that I can see thru the iOS Simulator if an UIView is defined with (semi-) transparent content. But I can not make a screenshot of it, on the screenshot the effect is gone.
The (custom) navigation bar on top has alpha set to CGFloat(0.9).
Here a screenshot taken with an iPhone 6:
Zoom in and you can see thru the simulator window on Xcode. I assume this is a bug, or is it intended behavior of the OS X transparency effects? If it is intended, can I turn it off?
Ok, I have found the problem. Actually it is not a transparency effect but a display problem. I am using an iMac 27inch with an IPS LCD display, which suffers heavily from "screen burning". Xcode is standing on this position for hours so it burned in into the display. That's why I can not make a screenshot - it is a hardware problem.

Yeah this is going to be a hardware / screen problem. Should not translate to your app.

I would like to make screenshots of my app in IOS-Simulator. This works fine with CMD-S, but I have always black parts in my screen, because the windows is not autosized to the simulated devices screensize.
Is there a way to autosize the window to fit with the screensize of the simulator ?
Screenshot:
The white part is the content of the device. The black is obsolete and is a window from the MAC. When taking the screenshot from this, I still have to cut out the content to have a good screenshot.
This used to happen in earlier to iOS SDKS when you don't set a launch images for all devices.
In your case, I think you don't have the launch screen file set. this can be solved by setting that file at general section in the target's settings.
Alternatively, set launch screen images for all devices.
Check my answer here.
One more thing to try: At the top bar in simulator. choose the
Window menu then Scale and play with those values.
I solved it the following way, but I don't know what was the reason.
I removed the launchscreen as hasan83 suggested. This did not the trick yet.
I restarted the MAC
I started XCode ("Xcode"->"Open Developer Tools"->"IOS Simulator")
I started the ios simulator without starting my app. -> MAC-Windows fit with the simulated device screen
I started my app and now it looks as intended.
Thanks for helping to all involved people !
My iOS Simulator only show the content as a part of the screen. How can I fix it? I'm using XCode 6.3.1. Thanks
You just need to restart it. It can happen sometimes.
Force close simulator and start it again!
I am including this response for those, who like me, are seeking an solution for this problem after upgrading to Xcode 8.
The simulator began using only a portion of the display, as described in the question, when testing against iOS 8.x. The symptoms were that 1/4 of the display was showing if the window scale was set to 50%, 1/9 would show if the scale was set to 33%, etc. The entire display would show only if the scale was set to 100%, which is a real pain when using an iPad simulator.
The solution for me was to turn off "Optimize Rendering for Window Scale" under the "Debug" menu, which first seems to have appeared in Xcode 8. The 8.x simulators displayed properly after that.
Looking at the image..
I think it has something to do with the resolution/scale of the simulator.. I dont use Xcode 6.3.1 though...
since it's 5s the screen resolution/scale is x2.. so instead of 320x568 it must be 640x1136..
why dont you use the device frame rect to fill the screen? something like self.view.frame ?
its hard to guess what causing your problem,show us something that may help.. :)

Step 1: “Force Quit” the iOS Simulator
Step 2: Open “Spotlight Search” and type “Chameleon Wizard” (if you installed Chameleon Bootloader)
Step 3: In that popup window, click on “org.chameleon.Boot”
Step 4: Uncheck display_0, Graphics Mode(Clear that Dropbox also), cpus=1, npci=0x3000, dart=0. Below shows an image with checked items those mentioned here. Just uncheck it all.
Step 5: Restart your Mac and try.
I have an iPad app. When I used it in iOS 5 or 6 its working fine and the UI also seems to be fine. But the same in iOS 7 a black bar on top, bottom, left and right of the screen appeared. Including on the splash screen.
I had tried it by hiding status bar of all views.But I cant fix the issue.
- (BOOL)prefersStatusBarHidden
{
return YES;
}
Can any one know what is the reason?
The same thing happened to me as a result of downloading the latest version of Xcode
and all I had to do was adjust the frame of my view as it was altered during the download. It's so simple I didn't even think to try it.
How big are the bars? Is there any chance this is actually an iPhone retina app and this is iOS 7's new automatic scaling for the iPad's bigger display instead of the old '2x' mode?
Also, does it behave like this in the simulator and if so, can you post simulator shots of it running under iOS 6 and iOS 7?

Guys. Please help me.. I've searched everywhere, but couldn't find a solution.
I'm using Xcode 4.3.2 and have the IOS 5.1 simulator installed.
The problem is the iPad simulator doesn't show the iPad's frame, just the contents. So, the home button isn't visible, thus can't be pressed.
But, unlike the iPad simulator, the iPhone simulator works fine.
Please help, guys..
Thank you
Use ⇧ + ⌘ + h in place of the home button.
If you need to make the screen smaller, use ⌘+3 or ⌘+2 for the smallest and smaller screen sizes respectively.
Actually, I (and a colleague) have been seeing intermittent behavior, with the bezel sometimes showing up, and sometimes not, for the very same project (same version of iOS - 5.1, same build settings, etc). This happens even when simulator is set to show a normal (non-retina) iPad... sometimes it has the bezel, sometimes not.
So I doubt this is intentional design.... seems like a bug to us.......
Does anybody know why home button is missing for iPad simulator only?
Its a simple redesign to make more space for the simulator screen. You can trigger the home button from the menu Hardware > Home Or using the shortcut: ⇧⌘H.
I don't think this is an enhancement at all. This is by far a notorious bug and a bad one. I know that home button action can be reproduced by cmd-H or its double click by doing cmd-H twice, though it could activate the slow motion animations too (annoying!). My point here is that whenever you run the simulator and start testing doing rotations (cmd-arrows), at one point you won't be able to tell if iPad orientation is to the right or to the left!... there's no visual clue whatsoever!
Bad Apple!, bad Apple!
It appears it is looking at whether or not there is adequate screen resolution to display the bezel. For example, I have a 17" Macbok pro that I develop on (1920x1200 resolution). When I launch an iPad development project and the suimulator comes up on my Macbook pro's desktop, no problem, the bezel shows. But let's say I then drag it over to my external monitor which is 1920x1080, then quit and relauinch the simulator... it comes up without a bezel.
My co-worker who has a Macbook Pro 13" (lower resolution), never sees the bezel. I suspect the newer retina Macbook Pros will always show a bezel.
This is of course, al pertaining to the regular, non-retina iPad simulator. I am not sure if given adequate screen resolution, the iPad retina simulator would show a bezel or not?
See http://openradar.appspot.com/11017007 for the real answer: "Engineer who removed the bezel from scaled iOS Sim not thanked enough, probably"
I personally don't need more screen space for the simulator with my Thunderbolt 27" display. I'd like the frame back, thank you very much! I also noticed with this version the application icons often show as blank white icons, even for Safari and Photos.
No, but you can trigger it from the menu bar (Hardware -> Home).
