I'm not looking to get a scale of the size of screen. I'm trying to get the actual size of the screen. For iPhone 5. When I try to get the size of the iPhone 5 I get the size of the iPhone 4/4s.
Here is my code:
CGRect myScreen=[[UIScreen mainScreen] bounds];
But the size I get is the following:
po myScreen
(origin = (x = 0, y = 0), size = (width = 480, height = 320))
(origin = (x = 0, y = 0), size = (width = 480, height = 320))
But if Use the following line of code:
UIScreen *mainScreen = [UIScreen mainScreen];
po mainScreen
<UIScreen: 0x16d834b0; bounds = {{0, 0}, {480, 320}}; mode = <UIScreenMode: 0x16e68040; size = 640.000000 x 960.000000>>
But if I use:
po mainScreen.bounds.size
(width = 480, height = 320)
My question to you guys is how can I access to the size "size = 640.000000 x 960.000000" using UIScreen.
I really appreciate your help.
Simply use nativeBounds instead of bounds.

I have an app which is compiled in Xcode 10 on iOS 13 simulator. In one view there is a "tray" view which shows from the bottom when tapped, in iOS 12 it works perfectly, in iOS 13, the tap is calling the method, but the changes to the frame are not saving - I have included outputs from the debugger in comments so you can see what the outputs of the frame values are;
- (void) userClickActivityTray: (UITapGestureRecognizer *) gestureRecognizer {
if(self.activityTrayShown) {
/*
(lldb) po self.activityTrayContainerView.frame
(origin = (x = 0, y = 792), size = (width = 414, height = 104))
*/
[self hideActivityTray];
} else {
if (!self.activityTrayViewInitialFrameComputed) {
self.activityTrayViewInitialFrameComputed = YES;
self.activityTrayInitialFrame = self.activityTrayContainerView.frame;
}
/*
(lldb) po self.activityTrayContainerView.frame
(origin = (x = 0, y = 638), size = (width = 414, height = 224))
(origin = (x = 0, y = 638), size = (width = 414, height = 224))
(lldb) po self.activityTrayInitialFrame
(origin = (x = 0, y = 792), size = (width = 414, height = 104))
(origin = (x = 0, y = 792), size = (width = 414, height = 104))
(lldb)
*/
[UIView animateWithDuration:0.25 animations:^{
self.activityTrayContainerView.frame = CGRectMake(self.view.bounds.origin.x,
self.bottomView.frame.origin.y - self.activityTrayViewController.maximumHeight,
self.view.bounds.size.width,
self.activityTrayViewController.maximumHeight);
self.activityTrayBackgroundView.alpha = 1.0;
self.bottomView.alpha = self.dotsProgressView.alpha = 0;
} completion:^(BOOL finished) {
self.activityTrayShown = YES;
/*
(lldb) po self.activityTrayContainerView.frame
(origin = (x = 0, y = 557), size = (width = 414, height = 305))
(origin = (x = 0, y = 792), size = (width = 414, height = 104))
*/
}];
}
}
Layout system in iOS 13 is different, we had the same issue and in our case by switching layout from automatic to Translates Mask Into Constraints fixed the issue.
You can use yourview.layer.frame instead of yourview.frame
It worked for me.
I had the same issue when moving to iOS13.
In my case, the sizing constraints were overriding any change I was making to the frame, which was not the case on iOS12.
For my app to work correctly, I had to also update the NSLayoutContraint just before the "animateWithDuration" block, so that the new frame coordinates stay compatible with the layout constraints.
Hope that helps
only set .translatesAutoresizingMaskIntoConstraints 's View to YES, it worked for me.
Hope that helps
In the debugger, I get the following output regardless of the orientation...
print self.tableView.frame
(CGRect) $R2 = (origin = (x = 0, y = 0), size = (width = 1000, height = 1000))
Why doesn't the size change depending on the orientation?
I am trying to convert scroll view coordinates to window coordinates. However the resulting frame seems to be shifted by status bar height, what's confusing is that the height remains the same which is not right.
CGRect visibleBounds = CGRectMake(0, 0, CGRectGetWidth(self.scrollView.frame), CGRectGetHeight(self.scrollView.frame));
CGRect scrollViewFrame = [self.scrollView convertRect:visibleBounds toView:nil];
lldb log:
Printing description of visibleBounds: (CGRect) visibleBounds =
(origin = (x = 0, y = 0), size = (width = 320, height = 568))
Printing description of scrollViewFrame: (CGRect) scrollViewFrame = (origin =
(x = 0, y = 20), size = (width = 320, height = 568))
Turns out scroll view bounds can be used to calculate the frame for scroll view in window coordinates, regardless the fact that I see negative bounds, produced frame will be correct anyway.
[self.scrollView convertRect:self.scrollView.bounds toView:nil];
I'm getting in a bit of a muddle trying to draw some paintcode graphics code in the middle of the screen horizontally.
I'm really not sure if scale or landscape orientation affects this.
I've created a UIView subclass and addSubview in viewDidLoad like so...
MenuTitleView *fancyView = [[MenuTitleView alloc] initWithFrame:self.view.bounds];
[[self view] addSubview:fancyView];
Rather than the size PaintCode gave me...
CGRect textRect = CGRectMake(0, 0, 418, 129);
I'm trying to determine the screen / view width and the size of the canvas width.
I've tried various things without success.
CGRect screenRect = [[UIScreen mainScreen] applicationFrame];
CGFloat w = screenRect.size.width;
CGFloat width = 500;
CGFloat height = 200;
CGFloat x = (w - width) * 0.5f;
CGFloat y = 20;
CGRect textRect = CGRectMake(x, y, width, height);
Scale is not an issue, because Quartz and UIKit now work in 'points' rather than in pixels, so that's already accounted for. However orientation is not, [UIScreen mainScreen] will return the same rect either for applicationFrame or bounds etc, it's oblivious to orientation.
I like to put a solution in a category on UIView or UIViewController, because you'll reuse it plenty. something like this...
-(CGRect )workingCanvas{
CGRect screenRect = [UIScreen mainScreen].bounds;
BOOL landscape = UIInterfaceOrientationIsLandscape([[UIApplication sharedApplication] statusBarOrientation]);
CGRect result = CGRectZero;
CGFloat lesserDimension = (screenRect.size.width < screenRect.size.height) ? screenRect.size.width : screenRect.size.height;
CGFloat greaterDimension = (screenRect.size.width > screenRect.size.height) ? screenRect.size.width : screenRect.size.height;
result.size.width = (landscape) ? greaterDimension : lesserDimension;
result.size.height = (landscape) ? lesserDimension : greaterDimension;
if ([[UIApplication sharedApplication]isStatusBarVisible]){
result.size.height -= [[UIApplication sharedApplication]statusBarFrame].size.height;
}
return result;
}
if you want to position your view just in the middle of the screen try this
CGRect screenRect = [[UIScreen mainScreen] applicationFrame];
CGFloat width = 500;
CGFloat height = 200;
CGFloat x = CGRectGetMidX(screenRect);
CGFloat y = 20;
CGRect textRect = CGRectMake(x, y, width, height);
already tested is working
Good Luck!!
Playing around with iOS6 today, and I got stuck on checking view frame size under various orientations, which I thought I understood in iOS5. (I understand that auto-layout solves the basic problem in many cases, but still I feel I may need this check for various reasons?).
With auto-layout off, checking the view dimensions returns the right dimension size, but not the correct edge. That is to say in portrait on the iPhone the .width property = 320 and in landscape the .width property = 300, whereas I would expect 300 to be the value of the height dimension.
This is kind of weird to me as the self.view does scale properly to the window, but another view set to the frame of the self.view does not. This would be easy to fix by checking the orientation then getting the right numbers, I guess, but am I missing something obvious, or some new rule in iOS6?
//always gives aprox 300 for width despite device orientation
-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{
screenRect = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
screenRect = self.view.window.frame;
NSLog(#"screen rect size = %f x %f", screenRect.size.width, screenRect.size.height);
[imageView setFrame:screenRect];
}
//a button to check orientation. always gives aprox 300 for width despite device orientation
- (IBAction)checkScreenSize:(id)sender {
screenRect = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
NSLog(#"screen rect size = %f x %f", screenRect.size.width, screenRect.size.height);
screenRect = [[UIScreen mainScreen]applicationFrame];
NSLog(#"screen rect size = %f x %f", screenRect.size.width, screenRect.size.height);
}
