从plist创建NSArray

Question

Im trying to create an NSArray from a plist but for some reason the array never get initialised.

Heres the code -

NSString * path = [[NSBundle mainBundle] pathForResource:@"defaultWorkouts2" ofType:@"plist"];

    NSLog(@" ------ %@", path);

    NSArray * defaultWorkouts = [[NSArray alloc] initWithContentsOfFile:path];

    NSLog(@" ------ %@", defaultWorkouts);

Heres the console output -

2011-04-24 16:17:26.732 IntervalTimer[9778:207] ------ file://localhost/Users/darrenfindlay/Library/Application%20Support/iPhone%20Simulator/4.3/Applications/8FAC4993-D1BA-460F-9A56-8A6984CB8AB6/IntervalTimer.app/defaultWorkouts.plist 2011-04-24 16:17:26.733 IntervalTimer[9778:207] ------ (null))

Here is the plist file -

<?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>

Thanks in advance for any help, this is driving me crazy.

If you look at your plist file, it's holding a NSDictionary not a NSArray . You should change your implementation to:

NSDictionary * defaultWorkouts = [[NSDictionary alloc] initWithContentsOfFile:path];
