Error pulling NSDates from plist

Question

I'm trying to pull NSDates from my plist, in order to create Datecomponents, but trying to do so give me problems.

This is some of the code I'm using:

self.Array = [NSMutableArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"matches" ofType:@"plist"]];

NSDateComponents *todayComp = [[NSCalendar currentCalendar] components:NSEraCalendarUnit|NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit fromDate:[NSDate date]];
NSDateComponents *eventDateComp = [[NSCalendar currentCalendar] components:NSEraCalendarUnit|NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit fromDate:[Array valueForKey:@"date"]];

I'm getting the todayComp's correctly, but the eventDateComp's, which I'm trying to get frm the plist, gives an error.

The plist is an array of dictionaries, like this:

<array>
<dict>
    <key>date</key>
    <date>2011-12-13T00:00:00Z</date>
    <key>titel</key>
    <string>Tilburg - Oss</string>
</dict>
<dict>
    <key>date</key>
    <date>2011-12-13T00:00:00Z</date>
    <key>titel</key>
    <string>Amsterdam - Roosendaal</string>
</dict>
</array>

NSLog says something like this...

-[__NSArrayI timeIntervalSinceReferenceDate]: unrecognized selector sent to instance 0x6a8d050

...which probably holds that I'm not getting the NSDates from the plist in the right way, but I have tried some different things, but have no clue how to do it right. Help is greatly appreciated.

[Array valueForKey:@"date"]

You are using valueforKey: method on NSArray. 1) use objectAtIndex: to get an object from array; 2) Difference between objectForKey and valueForKey?

NSDate *eventDate = [[Array objectAtIndex:0] objectForKey:@"date"];
NSDateComponents *eventDateComp = [[NSCalendar currentCalendar] components:NSEraCalendarUnit|NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit fromDate:eventDate];

Tried to implement the code and works, but it only gets the date from the first dictionary (due to objectAtIndex being 0). How can I go through all the dictionaries and thus get all the dates? – user1048042 Dec 13 '11 at 13:37
