arrayWithContentsOfFile无法读取plist文件

Question

我有一个包含2个字符串的数组的plist看到图像:

在我的viewDidLoadi中添加:

NSString *file = [[NSBundle  mainBundle] pathForResource:@"Data"    ofType:@"plist"];

NSArray *array = [NSArray    arrayWithContentsOfFile:file];

NSLog(@"array = %@", array);

但我总是null为什么？感谢帮助.

更新:解决方案是你需要手动编辑plist文件(Xcode4默认使用Dictionnary)

<?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 version="1.0">
<array>
    <array>
        <string>HO</string>
        <string>HI</string>
    </array>
</array>
</plist>

很可能,你的plist是一个包含数组的字典(Xcode 4不允许创建以数组作为根对象的plists).尝试这样的事情:

NSString *file = [[NSBundle mainBundle] pathForResource:@"Data" ofType:@"plist"];
NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:file];
NSArray *array = [dict objectForKey:@"Array"];
NSLog(@"%@", array);
