Was trying to change several labels and images width depend on the screen bounds after device gets rotated. Here's what I've tried:
- (void)viewDidLayoutSubviews{
if( UIInterfaceOrientationIsLandscape( [[UIDevice currentDevice] orientation] )) {
CGSize newSize;
newSize = CGSizeMake([[UIScreen mainScreen] bounds].size.width,[[UIScreen mainScreen] bounds].size.height);
NSLog(#"%#",NSStringFromCGSize(newSize));
}else if (UIInterfaceOrientationIsPortrait( [[UIDevice currentDevice] orientation] )){
CGSize newSize;
newSize = CGSizeMake([[UIScreen mainScreen] bounds].size.width,[[UIScreen mainScreen] bounds].size.height);
NSLog(#"%#",NSStringFromCGSize(newSize));
}
}
It's supposed to log different width and height when I change the orientation
(like on iphone5 : {480,320} & {320,480})
works fine on ios8,
but I got the same size results testing both on ios7 simulator and ios7 device.
Any idea would be appreciated.
Only from iOS8
[UIScreen mainScreen].bounds
is interface-oriented (look at session "View Controller Advancements in iOS 8" of WWDC 2014), this means that in landscape mode on iOS8 height and width are reversed.
You can create an helper method like below to have the same behavior:
+(CGRect)getScreenBounds
{
CGRect bounds = [UIScreen mainScreen].bounds;
if (([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) && UIInterfaceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation)) {
bounds.size = CGSizeMake(bounds.size.height, bounds.size.width);
}
return bounds;
}

I know it's not a great idea to alter an app based on the screen size but I am trying to modify the camera and use a custom overlay image so I need to know the screen size. There are a bunch of solutions to detecting the screen size using macros etc I am using this:
-(void)detectPhone{
CGFloat width;
width= [[UIScreen mainScreen] bounds].size.width;
if(width==320) {
CGFloat height;
height = [[UIScreen mainScreen] bounds].size.height;
if(height==480) {
NSLog(#"iPhone 4/4s");
}
else {
NSLog(#"iPhone 5");
}
}
else if (width==375) {
NSLog(#"iPhone 6");
}
else {
NSLog(#"iPhone 6+");
}
}
Is there anything wrong with using this method or any situations where it wouldn't work? Ran it through the simulator seems fine. Any pointers would be appreciated. Thanks
Its fine this way, but you are comparing floats, so I would avoid using == for that, instead use >
I use this :
#define IS_IPHONE [[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone
#define PJ_SCREEN_WIDTH ([[UIScreen mainScreen] bounds].size.width)
#define PJ_SCREEN_HEIGHT ([[UIScreen mainScreen] bounds].size.height)
#define PJ_SCREEN_MAX_LENGTH (MAX(PJ_SCREEN_WIDTH, PJ_SCREEN_HEIGHT))
#define PJ_SCREEN_MIN_LENGTH (MIN(PJ_SCREEN_WIDTH, PJ_SCREEN_HEIGHT))
#define IS_HEIGHT_GTE_568 PJ_SCREEN_MAX_LENGTH >= 568.0f
#define IS_RETINA ([[UIScreen mainScreen] respondsToSelector:#selector(displayLinkWithTarget:selector:)] && ([UIScreen mainScreen].scale == 2.0))
#define IOS7_DELTA_HEIGHT (([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) ? 20:0)
#define IS_IOS7 ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0)
#define DEVICE_SIZE [[[[UIApplication sharedApplication] keyWindow] rootViewController].view convertRect:[[UIScreen mainScreen] bounds] fromView:nil].size
If you want to check device model, take a look at: Determine device (iPhone, iPod Touch) with iPhone SDK
I think you will have problems with iOS8. From iOS8
[UIScreen mainScreen].bounds
is interface-oriented (look at session "View Controller Advancements in iOS 8" of WWDC 2014), this means that in landscape mode on iOS8 height and width are reversed.
You can create a helper with a code like below:
CGRect bounds = [UIScreen mainScreen].bounds;
if (([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) && UIInterfaceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation)) {
bounds.size = CGSizeMake(bounds.size.height, bounds.size.width);
//Your code to detect the device
...
}
You should have the screen for one time only then you can use it in your entire app (whenever you need). For this you can have a variable CGSize deviceSize in AppDelegate.h and in AppDelegate.m in your - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions in first line of this method, you can get the device size like this,
deviceSize = [[UIScreen mainScreen] bounds].size;
and you can define a function like this,
- (CGSize) sizeOfDevice {
return deviceSize;
}
add it in AppDelegate.h like this,
- (CGSize) sizeOfDevice;
then you can use it with your delegate object.
Forgive me if this is a really stupid question I am just a beginner at all of this stuff. I want to make a separate interface for the iPhone 6 and 6 Plus but I don't know how the best way to be going about this is. This is a very simple app just to get myself more familiar with the language, etc. I was wondering if there is an easy way to tell if a user is using a 6 or 6 plus to make a separate interface for them. Thanks :)
Use single storyboard. Learn autolayout from raywanderlich, it think its a very good resource.
Also,now take advantage of the size classes introduced for ios 8 in xcode 6. This is called adaptive layout.
So instead of making the above four views for 3.5, 4, 4.7, 5.5 inch devices separately, and then worry about combining their respective landscape modes as well, just go for the 4 combination of size classes using auto layout (if possible, highly recommended) and relax for any other device size that may come into future.
To detect iPhone Version Please use below code.
if ([[UIScreen mainScreen] respondsToSelector:#selector(scale)]) {
if ([[UIScreen mainScreen] scale] == 2.0) {
if([UIScreen mainScreen].bounds.size.height == 667){
// iPhone retina-4.7 inch(iPhone 6)
}
else if([UIScreen mainScreen].bounds.size.height == 568){
// iPhone retina-4 inch(iPhone 5 or 5s)
}
else{
// iPhone retina-3.5 inch(iPhone 4s)
}
}
else if ([[UIScreen mainScreen] scale] == 3.0)
{
if([UIScreen mainScreen].bounds.size.height == 736.0){
//iPhone retina-5.5 inch screen(iPhone 6 plus)
}
}
}
Reference from Here
write this code in .pch file
#define IS_IPHONE_6 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 667.0)
#define IS_IPHONE_6_PLUS (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 736.0)
and wwhenever you need in any controller you simply check the condition.
Below are methods that do what you asked. One major thing to look out for is in iOS7 and below, when you check [[UIScreen mainScreen] bounds] for the screen bounds, it always lists the width and height as the same no matter what orientation the phone is in. So if it's an iPhone5 in landscape mode, it will still list the width as 320 and height as 568. In iOS8, this changed, now if that same iPhone5 is in landscape, it will list the width as 568 and the height as 320. Below are methods which account for this:
+ (BOOL) deviceHasFourInchScreen
{
return [DeviceType deviceHasScreenWithIdiom:UIUserInterfaceIdiomPhone scale:2.0 height:568.0];
}
+ (BOOL) deviceHasFourPointSevenInchScreen
{
return [DeviceType deviceHasScreenWithIdiom:UIUserInterfaceIdiomPhone scale:2.0 height:667.0];
}
+ (BOOL) deviceHasFivePointFiveInchScreen
{
return [DeviceType deviceHasScreenWithIdiom:UIUserInterfaceIdiomPhone scale:3.0 height:736.0];
}
+ (BOOL) deviceHasScreenWithIdiom:(UIUserInterfaceIdiom)userInterfaceIdiom scale:(CGFloat)scale height:(CGFloat)height
{
CGRect mainScreenBounds = [[UIScreen mainScreen] bounds];
CGFloat mainScreenHeight;
if ([OperatingSystemVersion operatingSystemVersionLessThan:#"8.0"])
{
mainScreenHeight = mainScreenBounds.size.height;
}
else
{
mainScreenHeight = (UIDeviceOrientationIsLandscape([[UIApplication sharedApplication] statusBarOrientation])) ? mainScreenBounds.size.width : mainScreenBounds.size.height;
}
if ([[UIDevice currentDevice] userInterfaceIdiom] == userInterfaceIdiom && [[UIScreen mainScreen] scale] == scale && mainScreenHeight == height)
{
return YES;
}
else
{
return NO;
}
}
Also here are the accompanying OperatingSystem class methods:
+ (NSString *) currentOperatingSystemVersion
{
return [[UIDevice currentDevice] systemVersion];
}
+ (BOOL) operatingSystemVersionLessThanOrEqualTo:(NSString *) operatingSystemVersionToCompare
{
return ([[self currentOperatingSystemVersion] compare: operatingSystemVersionToCompare options:NSNumericSearch] != NSOrderedDescending);
}
Put below lines in prefix.pch
#define iPhoneVersion ([[UIScreen mainScreen] bounds].size.height == 568 ? 5 : ([[UIScreen mainScreen] bounds].size.height == 480 ? 4 : ([[UIScreen mainScreen] bounds].size.height == 667 ? 6 : ([[UIScreen mainScreen] bounds].size.height == 736 ? 61 : 999))))
Now in programming you can say...
if (iPhoneVersion==4) {
NSLog("This is 3.5 inch iPhone - iPhone 4s or below");
} else if (iPhoneVersion==5) {
NSLog("This is 4 inch iPhone - iPhone 5 family");
} else if (iPhoneVersion==6) {
NSLog("This is 4.7 inch iPhone - iPhone 6");
} else if (iPhoneVersion==61) {
NSLog("This is 5.5 inch iPhone - iPhone 6 Plus.. The BIGGER");
} else {
NSLog("This is iPad");
}
However, I would say use one storyboard for all iPhones by learning autolayout.
I am developing an application that's working fine in IOS6. But in iOS7, the status bar overlaps with the view.
As an example :
I need the status bar first, and then my icons and Remove last .So Please give me any idea about how to remove the overlap.
but I need this
Please give me any idea about my problem
Xcode has iOS 6/7 Deltas which is specifically made to resolve this issue. You have to moved your views 20 pixels down to look right on iOS 7 and in order to make it iOS 6 compatible, You changed Delta y to -20.
Resize the height of views properly on iOS 6 You had to set Delta height as well as Delta Y.
You can see also this - Fix iOS 7 Status bar overlapping
-(void)viewWillLayoutSubviews{
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7)
{
self.view.clipsToBounds = YES;
CGRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenHeight = 0.0;
if(UIDeviceOrientationIsPortrait([[UIApplication sharedApplication] statusBarOrientation]))
screenHeight = screenRect.size.height;
else
screenHeight = screenRect.size.width;
CGRect screenFrame = CGRectMake(0, 20, self.view.frame.size.width,screenHeight-20);
CGRect viewFr = [self.view convertRect:self.view.frame toView:nil];
if (!CGRectEqualToRect(screenFrame, viewFr))
{
self.view.frame = screenFrame;
self.view.bounds = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
}
}
}
Try this code.use this code in your AppDelegate.m in did finishlaunching:
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
[application setStatusBarStyle:UIStatusBarStyleLightContent];
self.window.clipsToBounds =YES;
self.window.frame = CGRectMake(0,20,self.window.frame.size.width,self.window.frame.size.height-20);
}
This is the default behavior for UIViewController on iOS 7. The view will be fullscreen and the status bar will cover the top of the view. If you have navigationBar hidden, then you have to adjust all the UIView elements by shifting 20 points.
I'm trying to programmatically determine the current height and width of my application. I use this:
CGRect screenRect = [[UIScreen mainScreen] bounds];
But this yields a width of 320 and a height of 480, regardless of whether the device is in portrait or landscape orientation. How can I determine the current width and height (i.e. dependent upon the device orientation) of my main screen?
You can use something like UIInterfaceOrientationIsPortrait([UIApplication sharedApplication].statusBarOrientation) to determine the orientation and then use the dimensions accordingly.
HOWEVER, during an orientation change like in UIViewController's
- (void) willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
duration:(NSTimeInterval)duration
Use the orientation passed in toInterfaceOrientation since the UIApplication's statusBarOrientation will still point to the old orientation as it has not yet changed (since you're inside a will event handler).
Summary
There are several related posts to this, but each of them seem to indicate that you have to:
Look at [[UIScreen mainScreen] bounds] to get the dimensions,
Check what orientation you are in, and
Account for the status bar height (if shown)

Working Code
I usually don't go this far, but you piqued my interest. The following code should do the trick. I wrote a Category on UIApplication. I added class methods for getting the currentSize or the size in a given orientation, which is what you would call in UIViewController's willRotateToInterfaceOrientation:duration:.
#interface UIApplication (AppDimensions)
+(CGSize) currentSize;
+(CGSize) sizeInOrientation:(UIInterfaceOrientation)orientation;
#end
#implementation UIApplication (AppDimensions)
+(CGSize) currentSize
{
return [UIApplication sizeInOrientation:[UIApplication sharedApplication].statusBarOrientation];
}
+(CGSize) sizeInOrientation:(UIInterfaceOrientation)orientation
{
CGSize size = [UIScreen mainScreen].bounds.size;
UIApplication *application = [UIApplication sharedApplication];
if (UIInterfaceOrientationIsLandscape(orientation))
{
size = CGSizeMake(size.height, size.width);
}
if (application.statusBarHidden == NO)
{
size.height -= MIN(application.statusBarFrame.size.width, application.statusBarFrame.size.height);
}
return size;
}
#end
To use the code simple call [UIApplication currentSize]. Also, I ran the above code, so I know it works and reports back the correct responses in all orientations. Note that I factor in the status bar. Interestingly I had to subtract the MIN of the status bar's height and width.
Other thoughts
You could go about getting the dimensions by looking at the UIWindow's rootViewController property. I've looked at this in the past and it similarly reports the same dimensions in both portrait and landscape except it reports having a rotate transform:
(gdb) po [[[[UIApplication sharedApplication] keyWindow]
rootViewController] view]
<UILayoutContainerView: 0xf7296f0; frame =
(0 0; 320 480); transform = [0, -1, 1, 0, 0, 0]; autoresize = W+H;
layer = <CALayer: 0xf729b80>>
(gdb) po [[[[UIApplication
sharedApplication] keyWindow] rootViewController] view]
<UILayoutContainerView: 0xf7296f0; frame = (0 0; 320 480); autoresize
= W+H; layer = <CALayer: 0xf729b80>>
Not sure how your app works, but if you aren't using a navigation controller of some kind, you could have a UIView under your main view with the max height / width of parent and grows / shrinks with parent. Then you could do: [[[[[[[UIApplication sharedApplication] keyWindow] rootViewController] view] subviews] objectAtIndex:0] frame]. That looks pretty intense on one line, but you get the idea.
However, it would still be better to do the above 3 steps under the summary. Start messing with UIWindows and you'll find out weird stuff, like showing a UIAlertView will change UIApplication's keywindow to point at a new UIWindow that the UIAlertView created. Who knew? I did after finding a bug relying on keyWindow and discovering that it changed like that!
This is my solution code !This method can add to NSObject class's Categroy , or you can define a Top custom UIViewController class , and let all of your other UIViewControllers to inherit it .
-(CGRect)currentScreenBoundsDependOnOrientation
{
CGRect screenBounds = [UIScreen mainScreen].bounds ;
CGFloat width = CGRectGetWidth(screenBounds) ;
CGFloat height = CGRectGetHeight(screenBounds) ;
UIInterfaceOrientation interfaceOrientation = [UIApplication sharedApplication].statusBarOrientation;
if(UIInterfaceOrientationIsPortrait(interfaceOrientation)){
screenBounds.size = CGSizeMake(width, height);
}else if(UIInterfaceOrientationIsLandscape(interfaceOrientation)){
screenBounds.size = CGSizeMake(height, width);
}
return screenBounds ;
}
Note, after IOS8 , as Apple Document of UIScreen's bounds property says :
Discussion
This rectangle is specified in the current coordinate space, which takes into account any interface rotations in effect for the device. Therefore, the value of this property may change when the device rotates between portrait and landscape orientations.
so for the consideration of compatibility , we should detect the IOS version and make the change as below:
#define IsIOS8 (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_7_1)
-(CGRect)currentScreenBoundsDependOnOrientation
{
CGRect screenBounds = [UIScreen mainScreen].bounds ;
if(IsIOS8){
return screenBounds ;
}
CGFloat width = CGRectGetWidth(screenBounds) ;
CGFloat height = CGRectGetHeight(screenBounds) ;
UIInterfaceOrientation interfaceOrientation = [UIApplication sharedApplication].statusBarOrientation;
if(UIInterfaceOrientationIsPortrait(interfaceOrientation)){
screenBounds.size = CGSizeMake(width, height);
}else if(UIInterfaceOrientationIsLandscape(interfaceOrientation)){
screenBounds.size = CGSizeMake(height, width);
}
return screenBounds ;
}
Here's a handy macro:
#define SCREEN_WIDTH (UIInterfaceOrientationIsPortrait([UIApplication sharedApplication].statusBarOrientation) ? [[UIScreen mainScreen] bounds].size.width : [[UIScreen mainScreen] bounds].size.height)
#define SCREEN_HEIGHT (UIInterfaceOrientationIsPortrait([UIApplication sharedApplication].statusBarOrientation) ? [[UIScreen mainScreen] bounds].size.height : [[UIScreen mainScreen] bounds].size.width)
In iOS 8+ you should use the viewWillTransitionToSize:withTransitionCoordinator method:
-(void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator {
[super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];
// You can store size in an instance variable for later
currentSize = size;
// This is basically an animation block
[coordinator animateAlongsideTransition:^(id<UIViewControllerTransitionCoordinatorContext> context) {
// Get the new orientation if you want
UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
// Adjust your views
[self.myView setFrame:CGRectMake(0, 0, size.width, size.height)];
} completion:^(id<UIViewControllerTransitionCoordinatorContext> context) {
// Anything else you need to do at the end
}];
}
This replaces the deprecated animation method that gave no information about size:
-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)orientation duration:(NSTimeInterval)duration
As of iOS 8 screen bounds are now returned correct for current orientation. This means an iPad in landscape orientation [UIScreen mainScreen].bounds would return 768 on iOS <=7 and 1024 on iOS 8.
The following returns the correct height and width on all versions released.
-(CGRect)currentScreenBoundsDependOnOrientation
{
NSString *reqSysVer = #"8.0";
NSString *currSysVer = [[UIDevice currentDevice] systemVersion];
if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending)
return [UIScreen mainScreen].bounds;
CGRect screenBounds = [UIScreen mainScreen].bounds ;
CGFloat width = CGRectGetWidth(screenBounds) ;
CGFloat height = CGRectGetHeight(screenBounds) ;
UIInterfaceOrientation interfaceOrientation = [UIApplication sharedApplication].statusBarOrientation;
if(UIInterfaceOrientationIsPortrait(interfaceOrientation)){
screenBounds.size = CGSizeMake(width, height);
NSLog(#"Portrait Height: %f", screenBounds.size.height);
}else if(UIInterfaceOrientationIsLandscape(interfaceOrientation)){
screenBounds.size = CGSizeMake(height, width);
NSLog(#"Landscape Height: %f", screenBounds.size.height);
}
return screenBounds ;
}
if you want the orientation dependent size and you have a view, you can just use:
view.bounds.size
I wrote category for UIScreen, that works on all iOS versions, so you can use it like this:
[[UIScreen mainScreen] currentScreenSize].
#implementation UIScreen (ScreenSize)
- (CGSize)currentScreenSize {
CGRect screenBounds = [[UIScreen mainScreen] bounds];
CGSize screenSize = screenBounds.size;
if ( NSFoundationVersionNumber <= NSFoundationVersionNumber_iOS_7_1 ) {
UIInterfaceOrientation interfaceOrientation = [[UIApplication sharedApplication] statusBarOrientation];
if ( UIInterfaceOrientationIsLandscape(interfaceOrientation) ) {
screenSize = CGSizeMake(screenSize.height, screenSize.width);
}
}
return screenSize;
}
#end
Here is a Swift way to get orientation dependent screen sizes:
var screenWidth: CGFloat {
if UIInterfaceOrientationIsPortrait(screenOrientation) {
return UIScreen.mainScreen().bounds.size.width
} else {
return UIScreen.mainScreen().bounds.size.height
}
}
var screenHeight: CGFloat {
if UIInterfaceOrientationIsPortrait(screenOrientation) {
return UIScreen.mainScreen().bounds.size.height
} else {
return UIScreen.mainScreen().bounds.size.width
}
}
var screenOrientation: UIInterfaceOrientation {
return UIApplication.sharedApplication().statusBarOrientation
}
These are included as a standard function in a project of mine:
https://github.com/goktugyil/EZSwiftExtensions
float msWidth = [[UIScreen mainScreen] bounds].size.width*(IS_RETINA?2.0f:1.0f);
float msHeight = [[UIScreen mainScreen] bounds].size.height*(IS_RETINA?2.0f:1.0f);
if ( UIInterfaceOrientationIsPortrait(self.interfaceOrientation) ) {
os->setWidth(MIN(msWidth, msHeight));
os->setHeight(MAX(msWidth, msHeight));
} else {
os->setWidth(MAX(msWidth, msHeight));
os->setHeight(MIN(msWidth, msHeight));
}
NSLog(#"screen_w %f", os->getWidth());
NSLog(#"screen_h %f", os->getHeight());
However, on iOS 8.0.2:
+ (NSUInteger)currentWindowWidth
{
NSInteger width = 0;
UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
CGSize size = [UIScreen mainScreen].bounds.size;
// if (UIInterfaceOrientationIsLandscape(orientation)) {
// width = size.height;
// } else {
width = size.width;
// }
return width;
}
use -> setNeedsDisplay() for the view you want to resize.
Some improvements on the answers offered here, in Swift:
let interfaceOrientation = UIApplication.shared.statusBarOrientation // (< iOS 13)
let screenSize = UIScreen.main.bounds.size
let screenWidth = interfaceOrientation.isPortrait ? screenSize.width : screenSize.height
let screenHeight = interfaceOrientation.isPortrait ? screenSize.height : screenSize.width
I'm using the following code to get the screen size width:
CGFloat width = [UIScreen mainScreen].bounds.size.width - 100;
But its giving width as "668.0" in portrait as well as landscape.
How can I get different width depending on the orientation of the device.
I ran into the same problem as you and all I could find is checking the orientation and calculate the height and width as follow:
UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
screenHeight = orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight ? 748 : 1004;
screenWidth = orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight ? 1024 : 768;
These size are for the the iPad obvioulsy but it could work for iPhone with the right dimensions.
Personally I think it's a bit poor but I couldn't find anything else.
Ok. In that case we can use,
CGRect viewFrame = self.view.frame;
int width = viewFrame.size.width;
int height = viewFrame.size.height;
CGSize winSize = [[CCDirector sharedDirector] winSize];
winSize.width will give you width and winSize.height give you height.
