Quick Question About .plist data

[cityofangels]

I have a plist that looks like the following:



To set the label to exercsieName, I am using the following code:

NSMutableArray *exerciseDetailArray = [[[NSUserDefaults standardUserDefaults] objectForKey:@"InfoArray"] mutableCopy];
 int indexValue = [[[NSUserDefaults standardUserDefaults] objectForKey:@"indexVal"] intValue];    
 self.name.text =[[exerciseDetailArray objectAtIndex:indexValue] objectForKey:@"exerciseName"];
 [exerciseDetailArray release];

I want to also set a label to muscleName, I tried adding the following but it didn't work.

self.muscle.text =[[exerciseDetailArray objectAtIndex:indexValue] objectForKey:@"muscleName"];

Any suggestions?

I tried this, but it isn't working properly either:

    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
    NSString *path = [[NSBundle mainBundle]pathForResource:@"data" ofType:@"plist"];
    NSMutableArray *rootLevel = [[NSMutableArray alloc]initWithContentsOfFile:path];
    self.muscleArray = rootLevel;
    self.muscle.text = [[self.muscleArray objectAtIndex:indexPath.row]objectForKey:@"muscleName"];
    [rootLevel release];

I'm confused. You posted data from the middle of a plist. It shows an entry, item 2, from the middle of an array. It isn't clear what is the outermost object in that plist.

Then you posted code that's reading data from NSUserDefaults, with a key of "InfoArray". Is what you posted one entry from the "InfoArray" structure you're reading from user defaults?

What you showed is this:

Array entry 2
--Dictionary
----Key "exercises"
------ array
----------item 0
------------ dictionary
-------------- key "exerciseName"
---------------- string "Balance Board"
----Key "muscleName"
------ string "Calves"

Your code never reads the "exercises" key from the outermost dictionary array entry 2, so I don't understand how the first block of code works.

The second block of code is written as if the same dictionary that contains the "exerciseName" key also contains a "muscleName" key, but it does not. From the little image you posted, I can't tell for sure what the structure of your file is. It looks like the outermost dictionary contains the key/value "exercises" and the key/value "muscleName". Thus, you need to fetch the "muscleName" key/value from the same dictionary you used to read your "exercises" key/value pair. But, as I said,you did not show how you're reading the "exercises" key/value.

You need to show us a more complete picture of what's going on.

Thanks,

Here is a full picture that should show the structure of the .plist

Both methods I had are loading data from the same plist. I used the first method to successfully update a label with exercise name. I also used the second method to successfully create muscleArray elsewhere to load a tableView.

What I need to do is use that muscleArray and load the label with the muscleName depending on what muscle from the tableView was selected.

To repeat:

The first code you posted that reads "exerciseName" gets an object from an array, and assumes it's a dictionary. It then looks for the key "exerciseName" in that dictionary.

Your second block of code tries to read another key "muscleName" from the same dictionary. There is no key "muscleName" in that dictionary. Instead, "muscleName" is is a key in a parent dictionary. That's why it doesn't work. You need to look at your data carefully, and pay attention to the grouping of your objects. Either the data is not structured correctly, or your code is not written to read the structure correctly. I don't have a clear enough understanding to tell which. It's up to you to figure it out.

Thanks Duncan.

So my data is structured correctly, but my code is not written to read the structure correctly. So how can I edit the method to reflect this?

Each exerciseName's parent has a muscleName.

I pointed you at the problem, now you need to think it through for yourself.

I tried this but no luck either. It works elsewhere in my code to load a tableView with muscleName items.

NSString *path = [[NSBundle mainBundle]pathForResource:@"data" ofType:@"plist"];
NSMutableArray *rootLevel = [[NSMutableArray alloc]initWithContentsOfFile:path];
self.muscleArray = rootLevel;
rootLevel release];
label.title = [[self.muscleArray objectAtIndex:indexPath.row]objectForKey:@"muscleName"];

I don't understand why it works there but won't work here to update the label.
