Xcode 4 *.plist file.
I am new to xcode 4.2.1 and I am slowly trying to learn how to use it.
I am working on creating a simple table view but I am having a strange problem.
The problem is when I create a new plist file but if I use the sample plist file in the class project it works just fine.
Now I know what you are probably thinking, why don't I use the sample file from the class and move on to the next project. Because the scope of the project was to learn how to create a simple table view along with knowing how to create a new plist file.
The sample file is only there to show you how the finish product should look like.
This is what I have tried so far to trouble shoot this problem.
I have copied the sample plist file and renamed it to something else (test.plist) and deleted all the data in the file and entered my own. Once I did this I edited my viewcontroller.m file and under the -(void) viewDidLoad and made the following changes.
{
NSString *myfile = [[NSBundle mainBundle]
pathForResource:@"test" ofType:@"plist"];
myplists = [[NSArray alloc] initWithContentsOfFile:myf
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
When I finished doing this I saved, build and ran the project and the iOS Simulator launched with my own data in the table view.
No problem here.
The problem is when I create my own plist (test2.plist), I do this exactly how the instructor in the video explains. Right click and select 'New File' in the 'choose a template for your new file' window. I select 'Resources' for iOS and select 'property list' and proceed to enter exactly the same data that I have entered into the test.plist.
Once I have completed this I go back to the same file viewcontroller.m file and update the
NSString *myfile with the new test2.plist file that I created, save, build and run but in this case I see nothing in the table view.
No data and no errors, this is the strange part. I get no errors in the build, I would like to think if the build ran successfully that I should see my data.
Any ideas what I may have missed in this video tutorial?

Plist is a XML file, I think your new plist differs from the correct plist for a NSArray in some headers. Can you send upload both plists?

Your new plist format is usable for NSDictionary not a NSArray. You should modify it as follows:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict> //Change dict to array
<key>Item 0</key> //Eliminate this line
<string>Broken</string>
</dict> //Change dict to array
</plist>
So it will be something like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<array>
<string>Broken</string>
</array>
</plist>
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict> //Change dict to array
<key>Item 0</key> //Eliminate this line
<string>Broken</string>
</dict> //Change dict to array
</plist>
So it will be something like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<array>
<string>Broken</string>
</array>
</plist>

Wow, it works!
Why didn't the build detect that the new plist format was unusable?
