I am having an issue with my app's sliding menu (segment) buttons. Two of the three buttons text are filled blocks, and I did not make any recent style changes to the app, let alone the app.scss file.
I am only seeing this on iOS devices (using an iPad mini and iPhone XS), not on ionic serve and Xcode simulators.
Is there a way to figure out the cause of this styling issue, or at least replicate the bug on either the Xcode simulators or ionic serve. I tried development and production builds, no difference.
My only guess is maybe something dealing with the new changes made with iOS Mojave as it made changes to the iOS app structure.
I am using a work-around by changing the font color to something close to the original.
Ex.
#777 to #777776
There has to be a reason it is doing this with just #777 or #fff.
Anyone noticed issues with apps that are created with Xcode 9 and do not seem to work on iOS 9.5.3 and in this case an older iPad 2?
I have a customer that downloaded my app that I’ve complied and uploaded with Xcode 9, but when he installs the app it crashes straight away, and on some occasions in a flash of 2 sec. will display the interface builder screen layout of the app (ie all the views, buttons etc that are visible on interface builder but with a normal app nicely hidden until needed etc).
The minimum development target in Xcode is set to 8.2 so I assume it will and should be backwards compatible?
Seems like the device is jailbroken.. My latest app version includes a check for a jailbroken device, and does not allow the app to load when it detects one.
I Could reproduce the exact behaviour when triggering this validation check.
I have an application build on Xcode 4.6 and iOS 6.1, but now apple requirement of submitting app must be published using Xcode 5.0. I set the deployment target to 6.1 in Xcode 5 and publish the app to app store.
I have a plan to shift completely to ios7 later but when I run app from Xcode 5 I am getting old UI but if i am downloading from store I am getting the ios7 UI which is not optimised and all loping very bad.
How to fix this issue?
Some UI elements are iOS version depended (no matter on what Xcode version your app was compiled). If you are using iOS 7 (on the simulator or on a real device) your UIAlertView for example will have the new iOS 7 UI. (Blurred white with blue writing)
I'm guessing that your iPhone has iOS 7 on it while you are trying to run your app from Xcode on iOS 6 simulator.
On a device running iOS 7, all of the system UI—such as alerts and
notifications—uses the iOS 7 appearance, even if your app is currently
using an earlier appearance.
iOS 7 UI Transition Guide
If you want to keep the legacy UI and still use Xcode 5 you can read this great tutorial.
I'd still advise against this, staying behind will stack more and more problems that you'll need to solve eventually.
i have an app that perfectly work in iOS 6, and when i update my iPhone to iOS 7 that was still work fine.
Then i update my XCode, and made some minor changes in my app (i did hide 2 UINavigation back bar buttons). After that i update my app (i want to point that i didn't change interface of my app), and when i update it from appStore and launch it on my iPhone there was a completely disaster. Interface objects such as segmented control or UIDatePicker automatically changes for iOS 7 version (style, color), back bar button item change it style, etc.
My question is, how can i force my app to launch on iOS7 with previous (iOS 6) design?
Replacing all the native views (switches, date pickers, alerts, action sheets, table views etc) by your own views that replicate iOS 6 appearance.
There are some open-source solutions, too.
However, it will be very hard, don't expect to do it in a few days.
Recommendation? Don't do it. Modify the apperance of your application for iOS 7. The users will expect it. You can't leave your application forever with deprecated appearance. I understand your feelings (my apps look terrible, too) but staying with iOS 6 appearance is not the solution.
You can build your app with iOS 6 SDK. But it can be only a temporary solution because Apple will not accept such apps in few month, I think.
Here you can see how to add SDK to Xcode:
Is it possible to install iOS 6 SDK on Xcode 5?
Compiling my app on XCode 4.6.3 and running it on iOS 7 works great.
Compiling my app on XCode 5 and running it on iOS 7 results a big UI mess I don't want to handle right now. (iOS 7 pickers, tabbars, tableviews etc')
Goal:
I want to be able to use XCode 5 and test my app on the iOS 7 simulator but still use the iOS 6 and lower UI and feel.
Reason:
I don't want to redesign my app to iOS 7 but I do want to make sure it runs fine on iOS 7 using XCode 5 iOS 7 simulator.
Is there a quick toggle on XCode 5 to force everything to stay the same?
Is doing something like using iOS 6 Base SDK in XCode 5 acceptable or a bit too much hacky?
Edit:
Using iOS 6 SDK doesn't help. You'll still get the iOS 7 look on your app, just more buggy.
This is the scenario:
Your app works fine on iOS 6 and lower
You want to test your app on iOS 7
If you have iOS 7 on your device you'll need XCode 5 in order to test it on it
If you want to test it on the iOS 7 simulator you'll need to install XCode 5 for it
Compiling your working app on XCode 5 will break all hell loose and will force you to redesign your app at least for iOS 7
The solutions suggested here so far will help you to see how your app will look like on iOS 7 but will not keep your iOS 6 and lower look on iOS 7.
Best solution I've found so far:
Update your current XCode to XCode 5
Download XCode 4.6.3 from here
Install it in a different location and Change the name of the app to XCode4 in order to differentiate between the two.
Find your XCode 5 app icon, right click it and select "Show Package Contents"
Locate the folder MacOS and move the xcode file outside of its
folder. Those last two steps are to prevent you accidentally opening a
project with XCode 5. An alternative is to change the default "Open With" app
but for some reason that didn't work
for me plus I wanted to be extra sure after I had one project opening with XCode 5
and the StoryBoard changed to be compatible to XCode 5 only. *
Open XCode 4.6.3 and run your project. In your simulator menu you
should now See iOS 7. Even if in XCode top bar you'll see AppName->iPhone
6.1 Simulator , selecting iOS 7 on the simulator will run your app in iOS 7 and keep everything the same.
After the above you'll have two versions of iOS simulator. Version 6 and version 7 that contains iOS 7 Simulator.
Step 5:
COPY iPhoneSimulator6.1.sdk
FROM
<YOUR XCode4 path>/Xcode4.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/
TO
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/
and set your base target to iOS6.1 (It will be listed after copying/pasting from xcode4) and
You cannot do this on the iOS 7 Simulator. You can do it in the iOS 6 Simulator (running under Xcode 5) and on the device (running iOS 7 as long as you build with the iOS 6 SDK). But there is no iOS 6 compatibility mode in the iOS 7 Simulator.
Note that iOS 6 compatibility mode is not a perfect replication of iOS 6. There are still various behavioral differences that you will likely have to test for and deal with. But the basic UI components are what you expect.
EDIT - Note that it is not possible to force an app to use the iOS 6 interface on an iOS 7 device using Xcode 5 (unless you make custom graphics). It is also not a good design approach. Users on iOS 7 expect a certain UI style, that's why they updated; so give it to them, don't force them back into an older interface.
If you really, really need the pre-iOS-7 interface, you can download a copy of Xcode 4 and build with that. However, starting February 1, 2014 Apple will stop accepting apps built with anything earlier than Xcode 5.0 (I think I saw something about that in the iOS 7 dev docs, but can't find the reference again).
Keeping the iOS 6 UI in your app, but building for iOS 7 is fairly straightforward. Make sure that you've set your Deployment Target as iOS 6.1 or earlier. Your Base SDK can still be set as iOS 7 though. Now, just follow the instructions below for each of your interface files:
Open your storyboard file or XIB file
Open the Utilities Panel on the right side.
Click on The File Inspector Tab. You should now see something like this:
Next go to the Interface Build Document Section and change the Builds For setting to iOS 6.0 and Later or whatever version you need.
Then change the View As setting to iOS 6.1 or earlier:
Xcode will prompt you, just confirm that you want to convert to the older UI.
Make sure to run your project in the iOS 6 Simulator. Otherwise, the iOS 7 Simulator will override it's own iOS 7 UI style. To download the iOS 6 Simulator, go to the Xcode Menu Bar. Select Xcode, Preferences. Then click on the Downloads tab. Finally, click on the Simulator(s) you need to download:
Then Run your app on the iOS 6 simulator:
Unfortunately, even disabling the iOS 7 UI in Xcode does not override it on the device / simulator. Unless you design custom UI elements, there isn't a way to maintain your iOS 6 UI on iOS 7. But as I showed you, you can continue to edit it in iOS 6 and build for iOS 6.
Linking the 6.1 SDK into Xcode 5 as described in the other answers is one step. However this still doesn't solve the problem that running on iOS 7 new UI elements are taken, view controllers are made full-size etc.
As described in this answer it is also required to switch the UI into legacy mode on iOS 7:
// put in main.m
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:#"UIUseLegacyUI"];
[[NSUserDefaults standardUserDefaults] synchronize];
Beware: This is an undocumented key and not recommended for App Store builds!
Also there are subtle differences to a version built using Xcode 4.6. For instance, transparent navigation bars behave differently (causing the view to be full-size).
However, since Xcode 4.6.3 crashes on Mavericks (at least for me, see rdar://15318883), this is at least a solution to continue using Xcode 5 for debugging.
Update: the crash of Xcode 4.6.3 on Mavericks only occurs when using LLDB. When switching back to GDB it works.
Contrary to my comments, I could actually follow the steps mentioned in the link.
What I tried was nothing sort of hacky:
Open XCode 4.6 app package (I have it still installed)
Go to Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs folder.
Copy iPhoneOS6.1.sdk folder.
Open XCode 5 app package.
Go to same Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs folder.
Paste.
I could then see iOS 6.1 as an option to base off my iOS project under Build Settings->Base SDKs.
However, even after doing this when I ran the app under iOS 7 simulator, I could sense no visual difference - all was rendered in default iOS 7 style - borderless buttons and bars.
No change after resetting simulator.
No change after changing storyboard version too.
So this again seems to confirm my assertion that this isn't possible.
If anyone tried it, I want to know.
I think that the only way to show iOS 6 controls on XCode 5 (and iOS7 Simulator) is to set the Base SDK of your Target to iOS 6.1(6.0).
You should copy the old sdk to XCode 5 like Nirav described and restart the XCode to make it visible under Base SDK selection.
My guess is that it didn't work for Nirav because he changed the settings of the project and in his case they have been dis-synchronized from settings of the target. So make sure that Base SDK for your target is iOS 6.0. Then it should work (at least it does for me).
This will give you a preview of how the app will look in iOS 6 using Xcode 5.
I saw this on a WWDC Video.
406 - taking control autolayout xcode 5 (about 32 mins in)
Using, the preview function within the storyboard.
This will allow you to pick between how it will look on iOS 7 and iOS 6.
The video shows a cool (almost hidden) feature of xcode that allows you to see, both previews of iOS6 and iOS7 at the same time, splitting up Xcode into 3 separate views
I'd like to add that while you may not be able to do it in the simulator, you can run your apps in compatibility mode on an actual device that has iOS 7.
Wow, this is a real mess. Thanks, Apple [*]
I got this (this: XCode 5 building iOS 6 apps) working for me, but I had several XIB's that were messed up, and it took a combination of several of the above steps to get it working.
1) Setup XCode 5 with iOS 6 base sdk
#Sha has good steps for that:
How to use iOS Simulator 7 \ XCode 5 to test pre-iOS 7 UI (without upgrading the app for iOS 7)
2) Go through each XIB and set it for XCode 4.6 mode
#RazorSharps post has good steps:
How to use iOS Simulator 7 \ XCode 5 to test pre-iOS 7 UI (without upgrading the app for iOS 7)
I'm not sure this was 100% required, but I did it and it works. (Perhaps I'll go back later and try without this, when I'm not still fuming).
3) Find any Navigation Controllers in XIB (or code) that may be set to Translucent, set them to Opaque
This was the trick for me. I had a root XIB that defined the Navigation Bar as Black Translucent, but all the XIB's that loaded overrode with their own appearance.
In 'real iOS 6' the controllers setting would override this (that is, the navbar would appear as opaque), but in iOS 6 Compatibility Mode on iOS 7 it wouldn't (that is, it would have an iOS 6 appearance, but be transparent, and mess up view layout).
#appledevtools: We appreciate your hard work, this is tough to get right. But here's a suggestion: When upgrading an existing project to XCode 5, IB xib's should be left in XCode 4.6 mode. Let the Editor > Validate Settings code offer to upgrade the settings, with a reasonable warning of the implications. Don't do this automatically & silently :-) Also, please find & fix why the navbar style changed in iOS 6 compatibility mode.
Good news is that we can set the base sdk to iOS 6.1 with XCode 5 now(in my case, it's Version 5.0.1 (5A2053)), and test & debug our pre-iOS7 designed app on iOS 7 simulator now.
For those who don't know how to set base sdk to iOS 6.1 for XCode, this link might be a guide.
Everything seems to work fine, the same pre-iOS7 design look & feel, except some os provided controls like ActionSheet look & behavior in the iOS 7 way.
BTW, I've upgrade my mac os to maverick yesterday, not sure whether this is an affect factor.
This worked for me but the explanation here needs cleaning up and detailing. If still desired, let me know and I will go into more detail.
It follows on from this answer
In addition to copying the iPhoneOS6.1.sdk folder, you also need to download the iOS 6.1 simulator (the proper way or copy it from an older installation of Xcode)
Then, make a duplicate of the iOS 7 simulator and replace it's plist with the 6.1 simulator's plist
Restart Xcode
You will then see two iOS 7 simulator options for each device option. One will be the normal iOS 7 simulator. The other will run your 6.1 SDK builds on the 7 simulator
WARNING You may not be able to remove the dummy simulator from Xcode's drop-down list afterwards (I haven't tried. It stuck around after I removed the dummy simulator folder)
Set deployment target to iOS 7.0 from deployment info. For that tap on project name and on first screen you will see deployment info... Change deployment target to 7.0. After that quit simulator, build and run app again.
