Code Coverage in XCode

While working with the latest version of Duplicate Image Detector I was hoping to see the amount of code coverage in the unit tests.

I was happy to see that the code coverage tools are built into GCC, but disappointed to see that it isn’t the easiest to meaniful statistics added to part of the build process. There is a great post at SuperMegaUltraGroovy.Com listing how to get code coverage enabled for your unit tests.

The one step I couldn’t complete is the code that needs to be inserted into the the Run Script after your test case run code. The code was a bit managled by Safari/Wordpress and even sorting that out I still had some issues.

Well after a bit of hacking around I found this code works pretty well (you will need to edit the framework name):


# Run the unit tests in this test bundle.
"${SYSTEM_DEVELOPER_DIR}/Tools/RunUnitTests"
# Run gcov on the framework getting tested
if [ "${CONFIGURATION}" = 'Test' ];
then
FRAMEWORK_NAME=DID-V2.0
FRAMEWORK_OBJ_DIR=${OBJROOT}/${FRAMEWORK_NAME}.build/${CONFIGURATION}/${FRAMEWORK_NAME}.build/Objects-normal/${NATIVE_ARCH}
mkdir -p coverage
pushd coverage
echo ${OBJROOT}
echo ${FRAMEWORK_OBJ_DIR}
find ${FRAMEWORK_OBJ_DIR} -name *.o -exec gcov -b -o ${FRAMEWORK_OBJ_DIR} {} \;
popd
fi


This will produce the following information after the unit tests when you run your test:


File '/Users/tupps/Development/LTConsult/svn/DID/v2/ImageMatchManagement.m'
Lines executed:70.00% of 40
Branches executed:100.00% of 34
Taken at least once:64.71% of 34
Calls executed:86.21% of 29
/Users/tupps/Development/LTConsult/svn/DID/v2/ImageMatchManagement.m:creating 'ImageMatchManagement.m.gcov'


I hope this helps get a few people closer to running unit tests and looking at their code coverage on the mac. A nice utility like shark would be fantastic for working through these files and all of the information that is exported.

Dynamic NSTableView Part II

Just another update NSTableView and creating it dynamically. If the NSTableView has its frame set then column resizing and scrolling seems to be screwed up.

By setting the frame of the scrollview and simply just calling init the NSTableView then the table seems to work correctly.

Dynamic NSTableView

If you need to add a NSTableView to a window or view in your code then it is not immediately obvious how to do this.

For example adding a button, all you need to do is initWithFrame for the button, then add the button to the main view.

However a NSTableView isn’t that simple. When you drag one out using interface builder you are getting a NSTableView wrapped up in a ScrollView. If you try to add the same way you would an NSButton you can’t see anything. What is needed is a ScrollView to wrap up the tableview.

I found this code which outlines how to setup a NSTableView. It is on the excellent cocoadev web site.

Enterprise Library Username and Password Connection String

I have a number of projects that use Microsoft’s Enterprise Library, but usually they use Integrated Security to connect to the SQL Server. Yesterday I had a project which had to connect to a SQL Server via username and password and found it wasn’t the easiest to work out how the dataconfiguration file should be set up. This is what I came up with that worked:


<connectionstring name="Sql Connection String">
<parameters>
<parameter name="Data Source" value="Server" isSensitive="false" />
<parameter name="Initial Catalog" value="Database" isSensitive="false" />
<parameter name="Integrated Security" value="false" isSensitive="false" />
<parameter name="Connection Timeout" value="10" isSensitive="false" />
<parameter name="user" value="sa" isSensitive="false" />
<parameter name="password" value="sa" isSensitive="false" />
</parameters>
</connectionstring>


Version 2.0 of Duplicate Image Detector

At present I am working on Version 2.0 of Duplicate Image Detector. At present it is nearly as quick as V1.0 for detecting duplicates, and it is now a matter of getting the user interface hooked up.

Version 2.0 will have the following goals:

• Simplified User Interface
• Easier access to advanced features
• Same speed as version 1.0

At present the user interface is coming along nicely and I beleive that it will be easier to use. In initial testing version 2.0 is nearly as quick as version 1.0 but still needs a bit of tweaking.

Once version 2.0 is out the door the next focus will be on improving the performance of the application.

New Website for Dius Computing

Dius Computing (the reason I haven’t posted much recently) have just launched their new website. It looks pretty good and people won’t be ashamed to link to it now

Useful Split View Sites

I have been hunting for information about NSSplitView and ran into a couple of sites with some decent information about Split Views and its intricacies.

Split View Help:
http://homepage.mac.com/jrc/contrib/ — Code for collapsing NSSplitViews programmatically.

http://www.cocoadev.com/index.pl?RBSplitView — An implementation of splitviews which gives you more control.

Generally Useful Site:

http://borkware.com/ — I am surprised I haven’t come across this site before. Seems to have a heap of useful code snippets.

I will let you know how I go with the intricacies of the NSSplitView

Stop Cocoa Bindings Feeling Like Cocoa Bindings - Part 2

After a bit of testing I found that there are a couple of issues. The first if you edit a field name and then you click the add button the results aren’t saved. This is easily fixed by deselecting the table first:

- (IBAction)addExtraField:(id)sender
{

[extraFieldsDefinitionTable deselectAll:self];
[NSEntityDescription insertNewObjectForEntityForName:@”ExtraFieldName”
inManagedObjectContext:[self managedObjectContext]];
[self performSelector:@selector(selectLastRowOfTable) withObject:nil afterDelay:0];

}

The second issue was when you add multiple items, their was a chance that the item wouldn’t be editable. An extra line is needed to select the row before you can edit the table.

- (void)selectLastRowOfTable
{

[extraFieldsDefinitionTable selectRow:([extraFieldsDefinitionTable numberOfRows] -1) byExtendingSelection:NO];
[extraFieldsDefinitionTable editColumn:0 row:([extraFieldsDefinitionTable numberOfRows] -1)
withEvent:nil select:YES];

}

Adding those two lines to the code makes it all good.

Stop Cocoa Bindings Feeling Like Cocoa Bindings

One thing that feels wrong with a bindings app is that when you add a new record to a table you then have to select that record with the mouse before you can edit that record. In my mind this feels just wrong and very ‘unMacintosh’. If you add a new playlist to iTunes the new playlist will be selected and ready to be renamed.

It is pretty easy to fix. In this case I am using Core Data and Bindings. You need to add one action to your controlling object and you also needs an outlet to the table in which the data has been added. In this case the object extraFieldsDefinitionTable is the NSTableView which is bound to the ExtraFieldName table in my data model.

- (IBAction)addExtraField:(id)sender
{
[NSEntityDescription insertNewObjectForEntityForName:@"ExtraFieldName"
inManagedObjectContext:[self managedObjectContext]];
[self performSelector:@selector(selectLastRowOfTable) withObject:nil afterDelay:0];

}


- (void)selectLastRowOfTable
{
[extraFieldsDefinitionTable editColumn:0 row:([extraFieldsDefinitionTable numberOfRows] -1)
withEvent:nil select:YES];
}

The reason this final part of code is called via a performSelector function is it allows the run loop to complete and update the tables data source from the core data model. If you are writing your own data source functions you can call reloadData on the table within the addExtraField function and then the editColumn without using performSelector.

Cocoa Bindings don’t stop my stupidity!

The new version of Body Diary presents a list of additional fields to the user to fill in. The number of fields is determined by the user. This data hasn’t been assigned to coredata so I decided that the easiest way to show this would be to create a mutable array and have that as the data source for Cocoa Bindings. Whenever a record is added to the system the array is recreated.

My first attempt at working with the data I went straight to the array and editted the data. This left the display out of sync with the data. A quick scan of the documentation pointed out that I should be instead using the NSArrayController to manipulate the data. I modified my code but I was soon stuck with nothing working. I tried everything, recreating controller objects, modifying my code, stepping through line by line. Nothing worked and I was getting very close to just rewriting everything as traditional table delegate methods.

I decided to remove all my debugging trials and strip everything back to the bare essentials. Once I did this I noticed that the class controlling the window was crashing when I quit. It turns out that my code to set the MutableArray that the NSArrayController was using was back to front. So instead of retaining the newArray, releasing the old, and then assigning the new to the old, I was retaining and releasing correctly but was assigning the old to the new.

A quick switch of the code and my NSArrayController was behaving perfectly. So the old “Problem Exists Between Keyboard and Chair” strikes again.
