iOS - IOS application failure when updating
If I start clean assembly and new installation, My application is installed and works fine, however, if I install the previous released version, and then overwrite this version with a new version, it will fail when you first start.
Steps on playback
- Install and run the previous version of my application (1.4) on the iPhone 4.
- Close the application and destruction process.
- Checkout latest version (2.0)
- Remove the assembly catalog
- Install and run
I launch Xcode 3.2.5, 4.2 SDK. My iPhone 4 - 4.2.1.
If you look at the logs of failures, it seems that I have a bad connection in one of my NIB, but there is no object trying to connect to the "View" property in my AppController. Sometimes it is identical to fail, except that it will say that this class does not match the key values \u200b\u200bfor the key ActivityIndicator. It is also uncomfortable because Grep confirmed that I have nothing in my project called ActivityIndicator.
I have three questions:
- Why my application collapses?
- Does anyone have ideas for further debugging that I can do? I have ended ideas about how to fix it.
- Is it possible (probably?) That when Xcode sets an assembly on your device, it requires labels that will not be executed when the application will be installed from the store. Does anyone know if it is so, and if so, then you know the way to simulate the accurate process of installing application store so that I could make sure that I do not kill the application for all updates?
Log of failures
2011-02-10 06: 58: 32.115 TheApp *** Terminating App Due to Uncaught Exception "NSUNKNOWNKEYEXCEPTION", REASON: "[
I have to add that the application fails before it falls into any of my code, i.e. Application: DidfinishLaunchingWithOptions: and ApplicationDidFinishLaunching: NEVER CALLED.

IOS 9 problems and solutions for users
The publication new version The popular IOS 9 operating system has become a real event for the happy owners of Apple brand devices. Like past versions, iOS 9 is not devastable. Users detect problems with updating iOS 9 and its further use. As a result, opinions were divided: some users are satisfied with the new features of the shell, and others believe that last update Reduced the productivity of the device and caused many difficulties among Apple mobile gadget owners. Especially often complaining about the problems of users who updated their gadgets in the first hours after the new version of the operating system is released. Of course, the creators work to eliminate all the shortcomings to force Android fans to go to iOS.
After iOS updates Until the 9th version, many users began to stand with new problems
Difficulties when updating to the latest version of iOS 9
All users have the opportunity to update their devices now, starting from generation iPhone 4S, iPad 2, iPod Touch. 5. One of the most common errors is the message " Software Update. Failed ", which indicates problems with downloading iOS 9. Usually this happens when the server is overloaded apple companies. In the first hours after the exit new iOS. 9 Many users were unable to access because of the huge flow of those who want to download the ninth version of the operating system. Even those who have completed the update successfully complained to low speed and for a long time Expectations.
We recommend updating iOS through connection in the iTunes program, but not "by air". With this method, the likelihood of problems is reduced. If when you try to install a new version pops up the "Software Update Failed" notification, you must wait a few hours or days until the server is free. Another advice for a successful installation of the new software: Make sure you use the most relevant version of iTunes.And the gadget has enough memory. To update improved iOS platforms 9 requires 1.5 GB free spaceWhat is an important advantage of the ninth version. Surely, many remember that to update previous versions It was required as 4.5 GB.
The device will show a message with a lack of memory. When installing past versions, an insufficient amount of memory led to the launch of the recovery procedure. The advantage of iOS 9 is the ability to temporarily delete unused applications. After the update is completed, all applications will be restored. There are two ways to release free space. One of them suggests manual removal of programs. You can also activate the "ALLOD APP Deletion" parameter.
Sometimes "freezing" of the installation process of all updates occurs. This is evidenced by the appearance on the Apple icon screen, in which nothing happens. Sometimes you can watch the status bar simultaneously. This is a sign of the occurrence of the installation failure. The first thing that can be done with the "freezing" of the installation is to perform a forced reboot called Hard Reset..
If such an action has not led to a positive result, you should connect the device to personal computer or laptop. This will allow you to enter the DFU mode. Second way - Run Recovery Mode with iTunes programs. Such recovery methods delete all the information. For this reason, we recommend creating backup Files, because without it is unlikely to restore lost data.
Problems with performance and high power consumption
Problems after updating iOS 9 occur quite often. The developers have improved many parameters that are responsible for performance and energy consumption. Despite this, many notice that their device requires frequent recharging after switching to a new operating system. The reason lies in incorrect custom Settings. Do not everyone know that now the users have the opportunity to analyze which applications take the battery charge, and limit their work. In order to find out such information, you must execute the settings command - the main - statistics - the use of the battery. This method will allow you to configure the optimal performance of the mobile device. It is possible to establish an active energy saving mode, which will be turned on automatically when the charge is only 20%.
Representatives of the old generation of Apple brand devices (for example, iPad 2 and iPhone 4S) do not always function correctly after the transition to the IOS 9 version. Sometimes a similar problem occurs on newer gadgets. It can be solved by such methods:
- Make a restart phone or apad. This will allow closing applications that function in the background, thereby increasing the volume random access memory.
- Run the setup command - the main - universal access - a reduction in movement and disable this parameter. After that, you will notice the change in the animation of the transition, which many users find visually pleasant.
- Use PhoneClean to clean the Siri voice assistant cache, unnecessary files Uninstalled applications, incorrect downloads and other data that occupy a place in the device's memory.
In addition to the "Reduce Movement" parameter, you can change other settings. visual effects. To speed up the device, it is necessary to increase contrast and reduce transparency. Such settings are in the "Universal Access" section, which can be found in the General Settings tab.
Affects performance and background update application. With slow work of your gadget, we advise you to deactivate this setting. In fact, background mode Provides permanent activity of the program. After turning off the parameter you will remain open access To update applications. The only condition that needs to be executed is the launch of this software product, after which you will see a update notification on the gadget screen. To deactivate the setting, perform a few simple commands: settings - General and disable the "Background Update" parameter.
Difficulties with data transfer via Bluetooth and Internet
Often the situation occurs when it is impossible to enter the Internet after completing the update process. If attempts to set up a normal iPhone or iPade wi-Fi work Stay unsuccessful, try to perform such actions:
- Reset all settings.
- Activation of aircraft for a few seconds.
- Change DNS parameters. To do this, you must execute the command: Settings - Wi-Fi - open the parameters using the "I" icon - in the DNS field to change the value to "8.8.4.4" or "8.8.8.8.8".
- Disable the parameter " Wi-Fi network" It can be done in this way: Settings - Privacy - Geolocation Services - System Services. Such a command will not turn off the entire module of the wireless network, but only makes changes to the setting system for determining the exact location of the gadget.
Often there are situations in which the mobile Internet does not work, in particular, 3G, GPRS, LTE. Most. simple method Correction of the work failure will be a reboot of the gadget. If it did not give positive result, Try to deactivate and then activate the "Cell data" parameter. It is in the Cellular Communications Settings tab. You can try to activate the airrest briefly, after which it is to test the work of the mobile Internet. If such methods did not help, the gadget settings are needed.
After completing the device update to version of iOS. 9 Users are faced with the impossibility of transmitting information on the Bluetooth protocol. To date, this technology is often used to connect wireless accessories. In the new version of this operating system, the compound may unexpectedly disappear during operation or at all be inaccessible. To solve the problem, you must turn off the protocol and restart the device. Alternatively, you can reset the network settings. Many helps repeated connection Devices. To do this, you need to implement the setup command - Bluetooth - make the selection of the device - click "I" - select the "Forget this device" parameter. After that, follow the same actions to activate the device.
After installing the IOS 9 version, unforeseen problems occur. As a rule, they are a consequence of minor flaws of the system that will be corrected by developers after several weeks of using a new shell with a wide range of users. We recommend performing updates after this period of time expires to minimize possible error risks. Many problems can be corrected by setting the correct gadget settings. Summing up, we can say that iOS 9 is operating systemhaving improved, in comparison with old versions, interface and performance.
