I have added a gpx file to my project; its name is TrailOfHistory.gpx. I have edited my project's scheme so that this file will be used by Xcode 9 to perform locations updates.
Here are screen shots of the scheme's Run and Test configurations wherein I have designated that the gpx file should be used:
When I run my application, user location updates (as given by the gpx file) begin automatically. I can watch this happening on my application's MKMapView.
In contrast, when I run one of my unit tests, user location updates do not begin automatically. I must instead perform the manual step of clicking the debug toolbar's Simulate Location button and choosing the gpx file; as shown in the following screen shot:
My ultimate goal is to arrive at a set of tests that can be executed by a continuous integration system. So, clicking on Xcode buttons is not going to fly.
Can anyone provide insight on this? In particular, can anyone say that he/she has had the experience of creating an XCTest wherein location updates began automatically (if so then I'll proceed with hope; currently I am unclear what expectations I should have)?
Note: I found this very similar question, over a year old. Hopefully I can generate some renewed interest.
I have managed to get this working using the following approach;
Go to the relevant scheme and select 'Edit Scheme...'
Select the 'Tests' for that scheme on the left hand side, and then click the 'Options' button for the UnitTest target.
Set the 'Location' variable to your GPX trail.
These steps are allowing me to test my CoreLocation functions as expected.
I feel like these options may have not been available when this question was written, but just incase this helps people with this issue going forwards I thought I would answer here.

I have a question, after I have whole built the AOSP source code, it generates couple image files, such as ramdisk.img, recovery.img, system.img, res-package.img,etc .
Right now, I am considering partial flashing my Android Box without formatting all of the system, for keeping some previous data remains.
Therefore, I just tried to use the command “adb sideload filename.img”, which filename might be ramdisk,recovery, etc.
Then, after I did so, the android system shows the message :
“footer is wrong”
“signature verification failed”
“Installation aborted”
There, what should I correct my command, to make the process correct?
as the figure shows enter image description here
And, my methods to do so is trying to refresh a new system feature, but keep the previous data, such as APPs, or user data, remain, does anybody have other good suggestions? Thank you in advance.
it depends on the flash type and file-system you are using, and it is not possible to partially flash in the partition, but you can update the partition.
First of all, I'm not using Core Data, I'm using SQLite only.
I save the data in the table and then query them by opening the app and looking at the data using SQLiteStudio. I even create a LOG to check that the data is saved, and yes, it is saved.
But when I STOP and run the simulator again to consult, there is no more data!
Is Xcode overwriting the database every time? Or is something else happening that is outside my limited knowledge?
Without knowing more about how your application is setup, how you've got your app configured to build, or how it operates on the SQLite DB file in question I'll only be able to offer some pointers in things you can go check out about your code and build configuration that may be the source of your phantom deletions. Of course, if you have other info to provide, I'd be happy to edit my answer!
Case 1: 'Create DB' always running?
One thing that may be tripping your app up is what happens leading up to the decision to create a new SQLite DB file or look/open an existing file. If the code creating an empty DB is always running, then each time your app starts, your old DB file is getting overwritten with a blank DB.
Case 2: Using a 'starter' or 'template' empty database?
Sometimes developers may provide a blank database that contains the initial database schema (the general tables and structure) as well as some default or sample data. If your app does this, perhaps the logic leading up to the decision to apply that default database is accidentally always being triggered? If so, use of NSUserDefaults to record a boolean indicating the DB was successfully created may be an avenue to use to skip past the 'Load my starter DB' code. Alternatively, you could check for the existence of your DB file, or see if the contents of a specific table are different from the template data, etc.
Case 3: Different Behavior between 'Build & Run' vs. 'Run Without Building'
There's a not-so-well-known option in the Product > Perform Action menu labelled 'Run without Building' that will essentially kickoff another Debug session using the version of the application you just finished running in the Simulator or on Device. When you use this option do you see any different behavior with your database or is it still blank?
Case 4: Different Behavior when run directly in Simulator outside of an Xcode debugging session?
Part of the 'Run' operation is a build phase which may trigger the 'Copy Resources' phase even if your app hasn't changed since the last execution (as you suggest is the case in your question). If you are providing a stock 'default' or 'template' DB file and your app is simply opening and editing that 'template' during the first execution of your app, then Xcode may be replacing it with a clean copy on the subsequent 'Run' operations where 'Copy Resources' is happening. A way to test this avenue:
Build and Run your app to the simulator using Xcode like normal.
Perform some operations that would result in the creation or editing of data in your app's database.
Click the stop button in Xcode to return to the Simulator home screen.
Double-click the home button on the simulator (or if there is no home button, press CMD+SHIFT+H twice to bring up the multitasking bar and force-quit out of your application.
Check and see if your DB file has data in it.
If no data, then there is an issue persisting your changes into the database and we need to get that problem solved first. Otherwise:
Relaunch your app directly from iOS Simulator and perform different operations that would result in more or different changes to the database.
Click on the home button to return to the iOS Home Screen.
Force-quit your appellation as was done in Step 4.
Check and see if your DB file data has changed (but still has data) or has blanked out.
Finally, make sure you are following Apple's guidance about where to store user-data, if you are inadvertently storing something in an incorrect file path doesn't typically result in blanking of data, it may be prohibiting writing of data which could be interpreted as your data getting overwritten especially if you are interrogating it while it still is residing in an in-memory process. There's some really useful guidance about file paths in the Table 1-1: (http://developer.apple.com/library/ios/#documentation/FileManagement/Conceptual/FileSystemProgrammingGUide/FileSystemOverview/FileSystemOverview.html)
Locating your Simulator App on your Mac's Hard Drive
To be thorough (and you may already know about this!), iOS Simulator applications are stored on your Mac's hard drive just like other files on your machine. Their organization mimics that of a physical iOS device. To get to your App and its data:
Open a new Finder window.
Press CMD+SHIFT+G or choose 'Go to Folder' from the 'Go' menu.
Paste the following into the 'Go to Folder' box then click 'Go': ~/Library/Application Support/iPhone Simulator/
Select the folder that matches the iOS version of the simulator you built to.
Click on Appications.
You'll then be presented with zero or more folders, each folder that appears will have a string of digits separated by hyphens. Navigate through this list until you find the one containing your app. You can then browse, and copy data out of this folder to somewhere to be examined by other tools on your Mac.
I am trying to develop QRCode reader application in iPhone.
I am trying to use ZXing SDK. i have successfully run the sample application given by ZXing. But i ma trying to develope new application as per instructions in Readme given by Zxing. but when i am trying to add ZxingWidget in build phases. it going add but it shows like below
I think it will getting problem to me. When i am trying to run application it will give erros like Lexical or Prepocessor issue File not found.
Is am doing any thing wrong when am added to files to application.
Actaully first of all i added ZxingWidget.xcodeproj to my application by drag and drop. But it wont give any alert window would you like copy like similar when we adding images or files to xcode. and next i added cpp and iphone folders to xcode application. and later i added the frameworks as per read me.
Please any one help me in this issue.
Thanks in advance
Pretty hard to help without the real error message. In the Issue Navigator, you can Right Click > Reveal in Log to see the complete error that you can copy and paste.
That said, it sounds a bit like it can't find the headers (though I'm just guessing without the real error message.) If so, double check steps 4 and 5 of the readme.
if you run on real device, the problem will be solved.
I don't know the reason.
But I guess It's related to Build Products Path.
Dropbox has the option of adding a button to the Finder toolbar. It even appears in the 'Customize Toolbar...' window.
I can't find any documentation on how this sort of thing is done.... Does anyone know how to do this, or can anyone point me towards some documentation or sample code?
EDIT ONE:
I guess a start would be finding the location of the existing icons, and any related code.
I noticed that Dropbox has files in Library/DropboxHelperTools/Dropbox_u501 called mach_inject_bundle_stub.bundle and FinderLoadBundle which might be doing the magic. Dropbox is also putting the 'tick' badge on Finder icons. This code might be involved: github.com/rentzsch/mach_star
EDIT TWO:
A Dropbox talk by Rian Hunter about the process is here, at around 15:30
http://blip.tv/pycon-us-videos-2009-2010-2011/pycon-2011-how-dropbox-did-it-and-how-python-helped-4896698
Looking in the DropboxBundle file in the Dropbox_u501 shows the icons and some compiled code. The code suggests that Rian Hunter is the author: http://twitter.com/timeserena
Rian has his own version of the Mach Star code on his github - https://github.com/rianhunter/mach_star - tho it seems much older
EDIT THREE
There was a 'Code Injection Workshop' at Stanford a few weeks ago - http://stanfordacm.com/past/ - hosted by Rian. If anyone has notes from this please let me know!
You can use Finder Sync app extension(Starting in OS X v10.10).
A Finder Sync extension can:
Add, remove, and update badges and labels on items in a monitored folder.
Display a contextual menu when the user Control-clicks an item inside a monitored folder.
Add a custom button to the Finder’s toolbar.
Dropbox was using undocumented magic. There's no officially supported way to do this; the closest you can get without reverse engineering is Services.
(Update: As of macOS 10.11, what Dropbox was doing is no longer possible at all. System Integrity Protection now prevents code from being injected into system processes, such as the Finder.)
Rian's talk at PyCon 2011 (on blip.tv) does not explain anything more than "We reverse-engineered Finder." Although the mach_star stuff is valuable, it still doesn't explain how to get a sidebar icon working. And the Stanford 'Code Injection Workshop' has not posted any content about this method.
I've nm'd and class-dump'd both bundles that Dropbox installs for each user under /Library/DropboxHelperTools, and the output provides good insight. If I get back to it, I'll finish my research and post it. Odds are, it won't be for some time, so here's hoping this nudge helps someone else.
An easy intermediate answer that may be adequate for some people is to simply create icons that look like buttons.
e.g. I created 'new text file here' and 'new terminal here icons' for my Finder:
The method can be found here.
The disadvantage is that they must be square and do not have animations/menus or show up in 'customize toolbar' etc.
We have an 'enterprisey' system with a scheduling component which gets floored if any dialogs come up. If any modal dialogs come up in the processes it is running, it gets 'paused' and can't kick off any new processes.
Excuse me a minute ...
*goes outside*
*laughs*
*cries*
*comes back*
.. ahem ... so anyway we need some sort of tool/technique that can lurk in the background and automatically detect specific dialogs and click OK on them. Any recommendations?
The offending system is running in Windows XP.
(NB: changing the third-party-enterprisey system or making its developers sit on the naughty step until they improve it are not options in the short term)
From this similar question I found:
Buzof by Basta Computing
which did the trick.
There is also a product called DialogDevil which looked promising but didn't work in our situation for some reason.
AutoIT is absolutely perfect for this. You can use the tool to help identify the dialog, write your own simple code and distribute the "auto clicker" via exe. It lurks in the background by running from the task tray.
DialogDavil will require exact same parameters on your dialog (for which you want buttons to be autoclicked) every time that same dialog pops up. And thats why it didnt work for me in first pass. Then i changed the control file at the following path to remove the changing items (a text box text in my case)
C:\Users\userName\AppData\Roaming\DAIR\DialogDevil\control.xml
And then it worked like a charm.
HTH,
