iphone - 从plist创建NSArray

Question

我试图从一个plist创建一个NSArray，但是由于某种原因，该数组从未初始化。

继承人的代码-

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

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

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

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

继承人控制台输出-
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))
这是plist文件-

在此先感谢您的帮助，这使我发疯。

如果您查看plist文件，则该文件包含的是NSDictionary而不是NSArray。您应该将实现更改为:

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