I am having a weird problem in iOS7 and iOS6. If anyone could help me out.
Problem :
- in iOS6 and earlier the view coordinates starts after NavigationBar but in iOS7 the view coordinates starts after StatusBar and calculate NavigationBar in the View. So what ever looks fine in iOS6 will spoil in iOS7. The NavigationBar hides the top 44 px of the View in iOS7.
I tried to search on internet but could not find any proper solution. I can pragmatically arrange the views by iOS7 condition. But I know its not a proper way to do it. So if you know how to resolve this issue, please guide me. I have attached 2 screenshots one is from iOS6 and the other is iOS7 so you get a better idea of the problem.
Although iOS 7 is still in beta phase. But according to current docs, you can check the version and load your components accordingly. See this link ( You need to login to developer portal first ).
if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {
// Load resources for iOS 6.1 or earlier
} else {
// Load resources for iOS 7 or later
}
I have created a subview to display a mobile ad in my XCode Project. The ad loads perfectly fine and works with iPhone 5 but not with iPhone 4.
I am trying to get the ad to fix to the bottom of the screen on both iPhone 4 & 5 but it doesn't want to do it for iPhone 4.
I am not using Auto Layout and do not wish to - is there a way I can do this programatically or using interface builder?
Really stuck, seems simple but please help
If the frame of your ad view (let name it adView) is already set, you can do like this :
[adView setFrame:CGRectMake([UIScreen mainScreen].bounds.size.width-adView.frame.size.width,
[UIScreen mainScreen].bounds.size.height-adView.frame.size.height,
adView.frame.size.width,
adView.frame.size.height
)];
EDIT
In case of application display a status bar , it should look like :
[adView setFrame:CGRectMake([UIScreen mainScreen].bounds.size.width-adView.frame.size.width,
[UIScreen mainScreen].bounds.size.height-adView.frame.size.height - [UIApplication sharedApplication].statusBarFrame.size.height,
adView.frame.size.width,
adView.frame.size.height
)];
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 :-

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 can I enable "AutoLayout" programmatically. Actually I have to create an app which should run on iOS6 and iOS5 but we can enable "AutoLayout" in the XIB in iOS 6 only and it will not work on the iOS 5 so I am checking the iOS version and using if else condition for the appropriate task according to the iOS. So if app would be running on iOS 6, I will enable the AutoLayout otherwise I will write the code for AutoResizing. Please let me know if I am unclear at any point.
If you want autolayout on iOS6 devices but not iOS5 (unuspported) but still want to use nib's, you have to keep separate nibs. One for iOS5 and one for iOS6.
When loading your nib, check if autolayout is supported by checking if the NSLayoutConstraint class exists:
if (NSClassFromString(#"NSLayoutConstraint"))
//Load iOS6 nib with autlayout.
else
//Load iOS5 nib sans autolayout.
