I have a came across a rather annoying bug in one of my apps. In iOS7 when I hold down on a UITextView or UITextField to bring up the Magnifying Glass, nothing shows up in the magnified area. This problem is app wide and the only element that ever shows up in the circle area is the keyboard itself (when I drag my finger down to the top of it).
I have tried everything from View Controllers with only a single UITextView to UIWebView and the problem is app wide.
The magnifying glass works as expected on iOS6 devices, and the iOS7 simulator. But not on any of the devices I have tested it with running iOS7.
Any help would be greatly appreciated.
I fixed this by setting the windowLevel of my main window to a float value of 1.2 in appDelegate:
self.window.windowLevel = 1.2;
This is a sort of hack for iOS7 to raise the default level of your main window which is UIWindowLevelNormal (1.0) to 1.2
Had the same issue when using multiple windows at once. Setting correct .windowLevel value for each window for correct z-sorting solved the problem.
We have a similar problem where we were presenting a UIWindow over the top of the existing window and if they have the same windowLevel then the loupe displays the first window added.
example:
[applicationWindow (windowLevel = 0] <------------- [customWindow (windowLevel = 0)]
customWindow renders on top of applicationWindow just fine...but a loupe displayed over a textfield in custom window renders the contents of applicationWindow.
[applicationWindow (windowLevel = 1] <------------- [customWindow (windowLevel = 1)]
Same result. customWindow renders on top of applicationWindow just fine...but a loupe displayed over a textfield in custom window renders the contents of applicationWindow.
[applicationWindow (windowLevel = 0] <------------- [customWindow (windowLevel = 1.01)]
customWindow renders correctly, contents of loupe render correctly.
The way we solved it is by initing customWindow.windowLevel to be UIApplication sharedApplication].keyWindow.windowLevel + .01 (but this could be anything) before making our customWindow the keyWindow. Thanks #user2940692, your answer should probably be the accepted one... if you want it, i'll post our case as a question, you can answer it and I'll give you credit.
I had the same issue. I found that in Project -> Targets -> General that there was a nib listed in the "Main Interface". Once I removed that it works fine. I also tried setting the window level, and it worked, but it was just masking the true problem for me.
If you did not get any help from the above solutions, I found another problem which can cause this to happen. I had a UIWindow object in nib which was initialized in AppDelegate. That view had background color as [UIColor whiteColor]. Setting it to [UIColor clearColor] will resolve this problem.

I have a window with a fullSizeContentView and a transparent titlebar and hidden titlebar.
I don’t even want the titlebar, but I had to enable it to get rounded corners on the NSWindow.
Problem
An NSTextView, when placed near the top edge, doesn’t react to any clicks. It doesn‘t let me select any text, and doesn’t let me click links I added via NSAttributedString.
This issue disappears when I disable the titlebar altogether.
Any Help would be greatly appreciated. Thanks!

I’m trying to implement little “in-app notifications” that show peripheral status updates. I considered using NSAlert but I don’t want to prevent the user from interacting with the rest of the interface while the notifications are showing, so I decided to implement it myself.
The notifications are little, non-movable windows without a titlebar. They are basically just grey rectangles with rounded corners and a shadow that draw inside the main application window and contain one or a few lines of text. The first line of text is almost entirely behind the invisible titlebar which is why I’m having issues.
The only thing I need the notifications to do besides display text is link to webpages that contain more info about a notification’s message.
I feel like I might be approaching this wrong. If you have any suggestions or ideas on how to solve the problem, I’m eager to hear them. Thanks!
I finally figured it out!
I nailed it down to the contentInsets of the NSScrollView. (which your are for some reason forced to have around your NSTextView when creating it in Interface Builder)
The contentInsets were automatically being set to account for the invisible titlebar, even though the docs say that NSScrollView - automaticallyAdjustsContentInsets (which is set to YES by default and which I assume was causing this) doesn't do automatic insets for transparent titlebars.
After programmatically setting the scrollView's contentInsets to 0, everything works great!
In Objective C, you can set your scrollView's contentInsets to 0 like this:
NSScrollView *scrollView = (NSScrollView *)self.textView.superview.superview;
scrollView.automaticallyAdjustsContentInsets = NO; // Doesn't remove insets // Probably calling this too late
scrollView.contentInsets = NSEdgeInsetsMake(0, 0, 0, 0);
Here's a working example.
Hope this helps!
I'm having no luck trying to get NSPopover back to its 10.9 appearance when running in 10.10. I have a popover which is attached to an NSView that the user drags around. The popover must be transparent so the user can still see the position of the other UI elements underneath.
All works fine under 10.9 but now under 10.10 with Apple's new gimmicky blurs, I can't seem to get back to the same appearance on 10.10 (unless like me, the user has enabled "Reduce Transparency" in System Preferences > Accessibility. A preference change I can't enforce on end users!).
Have tried:
self.draggingPopover.appearance = NSPopoverAppearanceHUD;
self.popoverView.superview.appearance = [NSAppearance appearanceNamed:NSAppearanceNameAqua];
self.popoverView.appearance = [NSAppearance appearanceNamed:NSAppearanceNameAqua];
None of which make any difference to the popover's appearance on screen.
drawRect in my view subclass fills the background with my chosen color but ignores the alpha value and the popover is opaque.
Similarly I can use self.popoverView.layer.backgroundColor = ... but the alpha value is ignored there too!
Use:
[popover setAppearance:(NSPopoverAppearance)[NSAppearance appearanceNamed:NSAppearanceNameAqua]];
If a requirement is that the popover is transparent (regardless of any future design changes to popover), could you just set the popover window's (i.e. the popoverView's -window) alphaValue to some other value < 1.0?
You can set the Aqua appearance in the storyboard as well. Select the NSPopover's content view and use this setting:
I have a huge code base and I don't know where this came from? Is it a default thing on the storyboard?
How do I get rid of it? Is it called a 'UINavigationBar' ?
EDIT:
I found some navbar code, can I can change the background color to red, but I can't hide it. I have tried:
[navigationController setNavigationBarHidden:YES animated:NO];
[navigationController.navigationBar setHidden:true];
I'm running into a problem with a detached UIPopovercontroller and am hoping someone has seen this behavior before.
My app runs in Landscape mode and offers a number of popover elements using the presentPopoverFromRect call. Some are launched from within the top view while others are presented from a view buried deep in the display. The popovers seem to work fine if the popover is presented from the upper 2/3rds of the iPad's display however when attempting to launch a popover from the bottom 1/3 of the display the popover is displayed detached from the UIButton. The x coordinate appears to be correct, however the y coordinate of the popover tends to be in the middle or top of the iPad screen.
I've played around with presenting the popover using a fixed position by creating a CGRect object in the lower 1/3 of the display but when the iPad renders the popover it either renders the popover in the upper 2/3rd of the view or the very bottom of the screen (if I force the CGRect value to a large y value).
At this point I'm out of ideas and hoping someone on the forum has seen this or can make suggestions as to what to try.
Thanks for any and all help,

I was able to fix my issue and thought that I'd share my solution incase someone else has the same problem.
The solution was to add a call to set the popover size BEFORE calling presentPopoverFromRect.
[mySettingsPopoverController setPopoverContentSize:CGSizeMake(320, 320) animated:YES];
[mySettingsPopoverController presentPopoverFromRect:sender.frame inView:self.navigationButtonsView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
Before, I wasn't setting the popover content size prior to presenting the popover. In the viewDidAppear method of the viewcontroller of the popover I was resizing the popover to size to the tableview in the popover. Apparently by not setting the popovercontentsize before presenting the popover you get undefined behavior including the possibility of having the popover detach from the element that it is suppose to be attached to.

I want to change the height of an NSWindow titlebar.
Here are some examples:
And…
I could use an NSToolbar, but the problem is that I can't place views very height (For example: I can't place the segmentedControl higher than in the picture because there is still the titlebar)
If I remove the titlebar I can't place a NSToolbar and the window isn't movable.
Have you any ideas?
This is much easier than one would think. I too went on a quest to do something similar for my app.
Real App Store app:
My App Store app look-alike:
No disrespect to INAppStoreWindow, it is a very good implementation and solid. The only draw back I saw from it though was that there was a lot of drawing code along with hardcoded settings for the TitleBar colors which Apple can adjust at anytime.
So here is how I did it:
A) Create a standard window with a Title Bar, Close, Minimize, Shadow, Resize, Full Screen - Primary Window all set.
Note: You do not need a textured window nor should you set a title
B) Next add a standard toolbar with these settings:
Icon Only
Visible at Launch - ON
Customizable - OFF
Separator - ON
Size - Regular
Remove all the Toolbar Items and add only these in the following order
NSSegmentControl (51 x 24) -- | Flexible Space | -- NSSearchField (150 x 25)
C) In your content View directly under the toolbar add a regular sized NSButton set like so:
Bordered - OFF
Transparent - OFF
Title -
Image -
Position - Text below the button
Font - System Small 11
Ok, pretty easy so far, right?!
In your Window Controller or app delegate....
setup IBOutlet(s) to your NSButton(s)
Note: Remember to hook up your IBOutlet in interface builder
Ok don't be scared we have to write a tiny bit of code now:
In awakeFromNib or windowDidLoad....
Get the content views' superview (aka NSThemeView)
Remove your button from its superView
Set the frame of your button
Add the button back to the theme view
So the code would look similar to this:
NSView *themeView = [self.contentView superview];
NSUInteger adj = 6;
[self.btnFeatured removeFromSuperview];
self.btnFeatured.frame = NSMakeRect( self.btnFeatured.frame.origin.x,
self.window.frame.size.height - self.btnFeatured.frame.size.height - adj,
self.btnFeatured.frame.size.width, self.btnFeatured.frame.size.height);
[themeView addSubview:self.btnFeatured];
That's it! You can use your outlet to enable/disable your button, setup a mask image when selected, enable/disable the toolbar or even hide everything and add a window title. All of this without worry if Apple changes their standard Window Titlebars.
P.S. No private frameworks were used in this posting whatsoever!
INAppStoreWindow is a NSWindow subclass, it tell you how to change the height of title bar.
https://github.com/indragiek/INAppStoreWindow
http://iloveco.de/adding-a-titlebar-accessory-view-to-a-window/
This example tells you how to add buttons in the title bar.
You'd have to subclass NSWindow and do a custom window frame drawing. It's not only about a titlebar. It's about whole window frame (so you can, actually, put close/minimize/zoom buttons at the bottom if you wish).
A good starter is at "Cocoa with love" website.
There are a few new solutions based on INAppStoreWindow and without warning and log message, for anyone who wants to change the height of NStitlebar, change the position of traffic light, add an item(e.g. a NSbutton) on NStitlebar and change its position, please check below.
