I'm trying to display an UIImageView within a tab on an iPad. I hide the tab bar and I want the UIImageView to take up the entire screen, ie be full screen. I try resizing everything in sight and the image will not occupy the space used by the tab bar.
I've tried debugging, printing the frame for each view going up the view hierarchy. Everything looks ok until it gets up to UIViewControllerWrapperView which has the smaller size.
What is UIViewControllerWrapperView and how do I resize it?
have you tried reseting the frame on the UIImageView
[imageView setFrame:theController.view.bounds];

I recently updated my xcode to 4.5 but now my UIScrollView Doesn't work anymore, in my previous xcode I made the scrollview at the exact same way and placed a imageview background and some buttons in it, they scroll along when I scroll.
Now with this new xcode when I place something in it, it doesn't scroll at all. Only when I put textview in it and make the text longer then the screen then it will scroll, but even then when I place a button on it the button won't scroll along, just the text. It's realy annoying and I don't know what Im doing wrong.. I've been trying to find a solution to this all day.
my ScrollView is placed in my view and got size 320,480.
in my ViewDidLoad I have:
[scroller setScrollEnabled:YES];
[scroller setContentSize:CGSizeMake(320, 481)];
I also have a picture to make my setup more clear, When I run the project in this picture it does scroll because of the text length. the image background is 320x960 but the picture doesn't scroll along it should go to the bottom where to color becomes more dark.. I hope you understand what I mean.

I made a video showing what I do, showing that it doesnt scroll when I put something in it

set your scrollView contentSizes height more than its original height then it would be vertically scrollable for sure.
Try this -
[scroller setContentSize:CGSizeMake(320, 800)];
Then see it scrolls or not.
I have dragged a UIImageView onto the UIViewController window in storyboard. I used the handles to make it take up the entire window. I set the mode of the UIImageView to "Aspect Fit". My goal is for the picture to take up the entire window when the iPhone is held in the same orientation that the image was taken.
But for some reason there's a little bit of space above and below every image.
Also I have it set up for the navigation bar and status bar to disappear when the user touches the image by using a hidden UIButton. This works okay except that the image shifts down when the navigation and status bars come back into view. The image only shifts down when I have this code:
self.navigationController.navigationBarHidden = YES;
self.navigationController.navigationBarHidden = NO;
which I use to get the navigationBar to redraw itself below the statusbar because sometimes the navigationbar will be drawn underneath the statusbar (this happens when making the navigationbar and statusbar reappear at the same time.)
How can I make my images display full screen without all these quirks?
EDIT:
I think it may have something to do with this:
The camera's aspect ratio is 4:3 and the screen's aspect ratio is 3:2.
So there is simply no way for the camera picture to fill the screen
unless you're willing to crop is to 3:2. To do that, apply an
appropriate scale transform.
is it possible to apply an affinetransform to an image in a uiimageview?
You'll want to set wantsFullScreenLayout to YES on your instance of UIViewController. From the documentation for wantsFullScreenLayout.
When a view controller presents its view, it normally shrinks that
view so that its frame does not overlap the device’s status bar.
Setting this property to YES causes the view controller to size its
view so that it fills the entire screen, including the area under the
status bar. (Of course, for this to happen, the window hosting the
view controller must itself be sized to fill the entire screen,
including the area underneath the status bar.) You would typically set
this property to YES in cases where you have a translucent status bar
and want your view’s content to be visible behind that view.
If this property is YES, the view is not resized in a way that would
cause it to overlap a tab bar but is resized to overlap translucent
toolbars. Regardless of the value of this property, navigation
controllers always allow views to overlap translucent navigation bars.
I've got a button designed on Portrait Orientattion, when I switch to Landscape it doesn't appear, what should I do so that it stays all the time?
Make sure you set the proper AutoresizingMasks for your UIViews. For example, it might be that your button has a y-coordinate that is larger than the device's width and has a fixed top resizing mask, so if you turn the device to landscape mode it gets clipped. Doing this...
button.autoresizingMask = UIViewAutoresizingFlexibleTopMargin;
...will cause the button to shrink its top margin, moving on screen.
In your comment you mentioned that this is a split-view app, if your button is in the root view controller of the split view, you should probably add support for restoring the root view controller as a popover.
Edit: This was a result of my own stupidity - the website I was liking to (iphone optimised) was not resizing to take advantage of the extra space, other pages display full screen.
Hi,
I've been trying to create a view that has no navigation bar, just a UIWebView that takes up the entire screen with a button to exit the view. I've managed to find a solution to hiding the navigation bar, but the problem is, it leaves a 44px space at the bottom of the view. So what I have is a webview taking up 460px on the screen, then just a white area below.
In Interface builder I tried to edit the size of the view but it was greyed out and set to 460px. Is there a way to make it so the webview takes up all 480px?
Thanks for any suggestions.
Chris
You can set the size of UIVewView programmatically in this way:
myWebView.frame = CGRectMake(0, 0, 320, 480);
and place it by example in viewDidLoad method.
I am trying to create a mid-size screen for my app on iPad.
In didFinishLaunchingWithOptions(), I do this:
CGRect winRect = CGRectMake(100,100,500,500);
navController.view.frame = winRect;
the screen comes up fine and I can click around and do stuff until the orientation changes. It takes the screen to original full size - how can I make it stick to my winRect frame? I tried setting the parentViewController.view.frame/view.frame to winRect in willRotateToInterfaceOrientation() but no good.
Any ideas?
Thanks.
Generally, you shouldn't mess with the frame of a view controller's view. View controllers tend to resize their views on many occasions, for example when toolbars and navigation bars are hidden or made visible or when the interface orientation changes.
For custom-sized views, create a separate view, set its frame to your custom size and add it as a subview to your view controller's view.
