ios - 如何访问多级结构化 Plist

Question

如何从具有这种格式的 plist 访问特定的周计划？ 如果有人知道任何与多级结构化 plist 相关的教程，请提出建议。

下面的代码给出了存储在 Plist 中的全部数据

-(void)ReadAppPlist
{
    plistPath = [[NSBundle mainBundle] pathForResource:@"runplan" ofType:@"plist"];
    NSMutableDictionary * propertyDict = [[NSMutableDictionary alloc]    initWithContentsOfFile:plistPath];
    name = [propertyDict objectForKey:@"Run - 1"];

    NSLog(@"%@",name.description);  
}

plist 的格式如下。

 <?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>Run - 1</key>
        <dict>
            <key>Level</key>
            <string>Beginner</string>
            <key>Category</key>

                <key>Week 1</key>
                <dict>
                    <key>Day 1</key>
                    <string>Rest or run/walk</string>
                    <key>Day 2</key>

                    <key>Day 3</key>
                    <string>Rest or run/walk</string>
                    <key>Day 4</key>
                    <string>2.5 km run</string>
                    <key>Day 5</key>
                    <string>Rest</string>
                    <key>Day 6</key>
                    <string>2.5 km run</string>
                    <key>Day 7</key>
                    <string>30 - 60 min walk</string>
                </dict>
                <key>Week 2</key>
                <dict>
                    <key>Day 1</key>
                    <string>Rest or run/walk</string>
                    <key>Day 2</key>
                    <string>3 km run</string>
                    <key>Day 3</key>
                    <string>Rest or run/walk</string>
                    <key>Day 4</key>
                    <string>2.5 km run</string>
                    <key>Day 5</key>
                    <string>Rest</string>
                    <key>Day 6</key>
                    <string>3 km run</string>
                    <key>Day 7</key>
                    <string>35 - 60 min walk</string>
                </dict>
            </dict>
        </dict>

我不知道如何检索这些数据，如果有人知道解决方案，请帮助我... 提前致谢。

Using this answer:

NSString *errorDesc = nil;
NSPropertyListFormat format;
plistPath = [[NSBundle mainBundle] pathForResource:@"runplan" ofType:@"plist"];
NSData *plistXML = [[NSFileManager defaultManager] contentsAtPath:plistPath];
NSMutableDictionary *properties = (NSMutableDictionary *)[NSPropertyListSerialization propertyListFromData:plistPath mutabilityOption:NSPropertyListMutableContainersAndLeaves format:&format errorDescription:&errorDesc];

//Now get the nested dictionary for the key "Run - 1"
NSDictionary *name = (NSDictionary *)[properties valueForKey:@"Run - 1"];

//Now get the nested dictionary for the key "Week 1"
NSDictionary *name2 = (NSDictionary *)[name valueForKey:@"Week 1"];

基本上，您可以遍历层次结构获取 valueForKey: 的字典。
