Plist Array到NSArray没有对象

Question

所以我之前已经搜索过并阅读并成功完成了这项工作,但是我遇到了这个问题.

我有一个plist是一个字符串数组.我没有被读入数组的对象.我成功地为另一个控制器中的字典做了这个.所以这是我的代码.

    // Open plist and get brands
NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"brands" ofType:@"plist"];
NSFileManager *fileManager = [NSFileManager defaultManager];
if ([fileManager fileExistsAtPath:plistPath]) {
    NSLog(@"The file exists");
} else {
    NSLog(@"The file does not exist");
}

_brands = [NSArray arrayWithContentsOfFile:plistPath];

_catList = [[[NSMutableArray alloc] initWithCapacity:[_brands count]] autorelease];

这是我的plist.请注意,_brands数组被定义为NSArray*品牌,属性设置为非原子,readonly并合成为brands = _brands.

<?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">
<dict>
    <key>Root</key>
    <array>
        <string>Brand A</string>
        <string>Brand B</string>
        <string>Brand C</string>
        <string>Brand D</string>
    </array>
</dict>
</plist>

我看到有一个标签,但在Xcode中它显示为带有字符串的数组.不是字典>数组>许多字符串

PLists是他们心中的词典(注意<dict>标签).将文件读入NSDictionary,然后使用objectforKey:方法和Root密钥向字典询问数组.

NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:plistPath];
_brands = [dict objectForKey:@"Root"];
