I get a project from my friends and it is about cam. And In iPhone 6 when I open a view, touch Home button,back to the app, the app is no more full screen.I don't know why? the iPhone5 is work well.
Please help me! many thanks.
this is not a issue, you did not set compatibility with screens. because i-phone 6 has larger screen size(375*667) than i-phone 5 screen size(320*567). therefore you have to apply checks of compatibility.
CGRect screenSize;
screenSize = [[UIScreen mainScreen]bounds];
NSLog(#"%f",screenSize.size.height);
float height = screenSize.size.height;
if (height == 667)//this is i-phone 6 height
{
//change your view frame here, set according to i-phone 6 screen bounds
}

UIWebview scalesPageToFit is not working properly when running an iPhone app on iPad with iOS 7.
I set the scalesPageToFit = YES before loading the request to the WebView.
After the page loads, inspecting the HTML document width gives 769px while the UIWebView's scroll view frame width is 320. The scroll view zoomScale is 1 although you would expect it to be 0.41... (320/769). Any idea?
The problem is now fixed in iOS 7.0.3. But, if you can't go there, please read on.
This seems to be a defect in iOS7. To recap, the problem happens when you run a iPhone only app, compiled with iOS7 SDK, in a iOS7 iPad or iPad Mini. A temporary work around is to scale the scroll view of the web view. This makes the text look smaller than you will like, but, so far, this is the best solution I have seen.
- (void)webViewDidFinishLoad:(UIWebView *)webView {
CGSize contentSize = webView.scrollView.contentSize;
CGSize viewSize = self.view.bounds.size;
float scale = viewSize.width / contentSize.width;
if (scale < 0.9) {
NSLog(#"Zoom out fix for web view: %f", scale);
webView.scrollView.minimumZoomScale = scale;
webView.scrollView.maximumZoomScale = scale;
webView.scrollView.zoomScale = scale;
}
}
We have an ios-app and a webapp with the same integration problem. We had to solve this in the webapp by enforcing the 320 css. I consider this an ios7 bug and would expect a fix for this.

Today i am going to create an iphone application which is compatible with iphone4 and iphone5. Earlier i have changed iphone4 application views programetically by using below code to adjust controllers for iphone5.
CGRect screenBounds = [[UIScreen mainScreen] bounds];
if (screenBounds.size.height == 568) {
// code for iphone5
}
else {
// code for iphone4
}
am thinking this is difficult to track all the frames and sizes of controllers each and every time. I have created one sample app and also tried with Auto-resizing option(i have put check mark) at the starting of view and selected size Retina 4 full screen in inspector. And also selected simulator hardware-device is iphone Retina-4 inch
if i change simulator hardware-device is iphone Retina-3.5 inch then the screen is looking like
My question is without setting frames how can i achieve this problem.
Please help me.
Thanks in advance.
You can use this link for autosizing
http://blog.mugunthkumar.com/coding/supporting-the-iphone-5/
Instead of giving static numbers give frames dynamically. means instead of giving 320 give self.view.frame.size.width so you no need to check the device, just you need to add default splash screen.
You problem could be resolved easily using Autolayout feature provided in the XCode Version 4.x .
Go through the following link :-
http://www.raywenderlich.com/20881/beginning-auto-layout-part-1-of-2
By applying few contraints using Autolayout your problem could easily be resolved.
Happy Coding :)
I'm super confused about how the iPhone 4 and below apps are optimised for the iPhone 5. I'm a designer. How is optimisation done? Basically I have an app with loads of knobs and buttons and other interactive components. The way I see it, there are 3 options but what is the best way (or least, standard practice)?
1) Keep the layout the same for iPhone 5 but just add extra length on the background.
2) Scale the images/layout of components from iPhone 4 to iPhone 5 so everything is proportional.
3) Have completely separate images and different layouts for both. i.e for iPhone 5, I can move components to utilise the space more. The problem with this (and I'm not a developer) is that the interaction position of the components have moved so in effect, the iPhone 4 and 5 are separate apps?
To identify if it is a iphone 5 iphone, use this code in the file nameYourApp-prefix.pch:
//Macro iPhone5
#define IS_IPHONE_5 ( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )568 ) < DBL_EPSILON )
find the nameYourApp-prefix.pch file in the supporting files, the code must be written between:
# ifdef __ OBJC__
//Code Macro iPhone5
# endif
and then just use the "if" to check that device, like this:
if (IS_IPHONE_5) {
//Code for 4 inch screen
}else{
//Code for 3.5 inch screen
}
putting the macro in the nameYourApp-prefix.pch, all classes see it.
With a UIKit application, none of your options are ideal. You simply use Springs and Struts or Auto Layout to have your user interface elements snap to where they should be.
The solution is the same when switching between portrait and landscape orientation. You define which user interface elements can grow and which ones can't, which edges to snap to, etc.
Run it on the simulator to test the layout if you don't have an iPhone 5 device.
For example, for a UITableViewController, the UITableView should grow vertically on an iPhone 5 so that you see more rows.
I almost always have at least one control that would be nice to grow given the room. If you don't, then you'll probably just have more empty space at the bottom of the view.
How iPhone 5 Optimization Works
When you tell iOS that your app is optimized for the iPhone 5 (through use of a cleverly named image file), iOS uses your existing Springs and Struts or Auto Layout (whatever you're using) to rearrange the interface.
The first choice is the easiest and works pretty well. You'd only need to worry about having specific assets for full screen images, and make sure that NavigationBar and TabBar (in case your app have one), remains on top and bottom respectively.
Scaling other images/components such as buttons, you'll change the general aspect ratio (which you probably wouldn't want), since iPhone 4&5 display sizes only differ in height.
For developing app option two is better. Although you dont have to change all the images for iPhone 5 some images will me same like TabBarItem. But you have to create background image different for iPhone4 and 5.
Read out this apple document to create user interface.
And you can differentiate iPhone 4 from iPhone 5 using this code
UIBtton * btn = [[UIButton alloc] init];
CGRect screenBounds = [[UIScreen mainScreen] bounds];
if (screenBounds.size.height == 568)
{
btn.frame = CGRectMake(60,60, 205, 175);
//this is for iPhone5
}
else
{
btn.frame = CGRectMake(60,50, 199, 170);
//this is for iPhone4
}
Here my button place and length are different for iPhone 5 and iPhone 4
And set your control's hight and width according to iPhone Screen Size.
If you didn't, adjust your view layouts with proper auto resizing masks or look into Auto Layout if you only want to support iOS 6 going forward. You have to check height of [[UIScreen mainScreen] bounds].
Example:
CGRect screenBounds = [[UIScreen mainScreen] bounds];
if (screenBounds.size.height == 568) {
// code for 4-inch screen (iPhone 5)
} else {
// code for 3.5-inch screen (< iPhone 5)
}
Note that [UIImage imageNamed:#"yourImage.png"] will only load either "background.png" or "yourImage#2x.png", it will not load "yourImage-568h#2x.png" if it exists.
Check Auto-Rotation API as Well.

How do I support the taller iPhone 5 screen size?
I am new to iPhone and I have a small doubt. Now the iphone5 screen height is 568 and previous iphone's screen height was 480. How can we implement apps for iphone5.Should we check views or controllers all the time for iphone5 and below versions? If am wrong Please correct me.
Thanks in advance.
here are the points
*if you want to make use of full height of the iPhone5 create splash screen that's exactly 640x1136 pixels in size and name default-568h#2x.png
*if you have problem with rotation check
a)window.rootViewController = firstViewcontroller (dont add view to your window)
b)implement the new rorate delegate function
*Use viewDidLayoutSubviews rather than viewDidLoad to set up widget sizes relative to the window
*You can manually check the screen size and load the right image like this:
UIImage* myImage;
CGFloat screenHeight = [UIScreen mainScreen].bounds.size.height;
if ([UIScreen mainScreen].scale == 2.f && screenHeight == 568.0f) {
myImage = [UIImage imageNamed:#"myImage-568h#2x.png"];
} else {
}
myImage = [UIImage imageNamed:#"myImage.png"];
or use catogary from the following GIT gist
https://gist.github.com/3719620
Just use
CGRectGetHeight([UIScreen mainScreen].applicationFrame)
CGRectGetWidth([UIScreen mainScreen].applicationFrame)
to get screen's height & width.
in your project (in XCode 4.5) goto "Supporting File" group (which is automatically created).
you got to use those Default#2x.png/Default-568h#2x.png files. !!
That is the key change required for the OS to size the window to fill the iPhone 5 display. Redth# has posted a writeup on this and other size-related tweaks you might need to make.

I'm using UIWebView to load local 5 pages pdf file, the page content is perfect in iPhone (3.5 inch), but it's not resized appropriately in 4-inch, check the screen shot.
How can I fix it?
Thanks
I dont think you can fix it. UIWebView scales down pdf's to make them fit the iPhone screen, but it wont stretch them.
If the pdf is local as you say, you could always include 2 pdf files, one for iPhone 4inch and one for 3.5inch.
you can check the screen size for 4inch or 3.5inch
CGRect screenBounds = [[UIScreen mainScreen] bounds];
if (screenBounds.size.height == 568)
{
//for iphone 5
//for 4 inch
}
else
{
//for iphone 4
//for 3.5 inch
}
