showing elements of dictionary - objective-c

Question

I have a plist file that contains array of dictionaries, and I'm trying to show in console the elements of the dictionnaries... here is my code:
NSString *path = [[NSBundle mainBundle] pathForResource:#"validrep" ofType:#"plist"];
descArray = [[NSMutableArray alloc] init];
NSString *key = [NSString stringWithFormat:#"test %i",i+1];
NSMutableArray *tabreponses = [[NSMutableArray arrayWithContentsOfFile:path] retain];
NSDictionary *dictreponses = [NSDictionary dictionaryWithObject:[tabreponses objectAtIndex:i] forKey:key];
[descArray addObject:dictreponses];
NSDictionary *dictionary = [descArray objectAtIndex:i];
NSArray *array = [dictionary objectForKey:key];
NSLog(#"the array is %#, it contains %i elements.",array,[array count]);
Till now everythig is working correctly and this is what the console is showing:
2011-12-14 14:52:33.845 Daltonien[1459:b603] the array is {
rep1 = "1 \U00e9toile derri\U00e8re un quadrillage ";
rep2 = "1 lettre B derri\U00e8re un quadrillage";
rep3 = "1 quadrillage seul ";
}, it contains 3 elements.
but it doesn't work when i try to show the first element of the array, i do it like this:
NSLog(#"the array is %#, it contains %i elements, the first element is %# .",array,[array count],[array objectAtIndex:i]);
This results in an exception:
Daltonien[1478:b603] -[__NSCFDictionary objectAtIndex:]:
unrecognized selector sent to instance 0x4b8cbd0
Daltonien[1478:b603] *** Terminating app due to

THANX for helping me.

Answer 1

The problem is this:
Your key, #"test1", is actually a dictionary, not an array...
To get the first key / value of the dictionary, you would do the following
[[myDictionary keys] objectAtIndex:0]
[[myDictionary values] objectAtIndex:0]

Answer 2

If you want the first object in your array, you'll want something like this:
[array objectAtIndex:0];
To loop through all of the objects, this will do it:
for (id someObject in array) {
// Do stuff
}
