Iphone 检索存储在plist文件中的数组数据

如何检索存储在plist文件中的数组数据

plist文件和源代码如下所示

------------------------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 version="1.0">
<dict>
    <key>Name</key>
    <string>abcxxx</string>
    <key>Phones</key>
    <array/>
    <key>item1</key>
    <string>121327777</string>
    <key>item2</key>
    <string>333333333</string>
</dict>
</plist>
---------------------------------------------------------



  -(id) init
{


    NSString *errorDesc = nil;
    NSPropertyListFormat format;
    phoneNumbers =[[NSMutableArray alloc]init];
    NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"testfile" ofType:@"plist"];
    NSData *plistXML = [[NSFileManager defaultManager] contentsAtPath:plistPath];

    NSDictionary *temp = (NSDictionary *)[NSPropertyListSerialization
                                          propertyListFromData:plistXML
                                          mutabilityOption:NSPropertyListMutableContainersAndLeaves
                                          format:&format errorDescription:&errorDesc];

    if(!temp){
        NSLog(errorDesc);
        [errorDesc release];
    }
    self.personName = [temp objectForKey:@"Name"];
    self.phoneNumbers = [NSMutableArray arrayWithArray:[temp objectForKey:@"Phones"]];
    NSLog(@"Label executed %@",[phoneNumbers objectAtIndex:0]);

    UILabel *name = [[UILabel alloc]initWithFrame:CGRectMake(-180, 100, 100, 20)];
    name.text = [phoneNumbers objectAtIndex:1];
    [self addChild:name];
    NSLog(@"Label executed %@",name);

您的plist XML看起来有点可疑。您所要做的就是调用NSDictionary的initWithContentsOfFile:method。例如

NSDictionary *temp = [[NSDictionary alloc] initWithContentsOfFile:plistPath];
self.personName = [temp objectForKey:@"Name"];
self.phoneNumbers = [[temp objectForKey:@"Phones"] mutableCopy];

但是，如上所述，您的plist看起来确实有点可疑，请尝试将其更改为Andy White提供的plist

UITextField的帧也很奇怪（取决于self的帧）
CGRectMake（-18010010020）
可能在屏幕外。
最有可能的是你根本无法读取plist，只需检查你的plist结构

 NSString *StringsFromPList = [[NSBundle mainBundle] bundlePath];
 NSString *itemPositionPlistLocation = [StringsFromPList stringByAppendingPathComponent:@"Words.plist"];
 _myDictionary= [[NSDictionary alloc] initWithContentsOfFile:itemPositionPlistLocation];
NSArray * items = [_myDictionary objectForKey:@"Root"];


<plist version="1.0">
<dict>
<key>Root</key>
    <array>
        <string>Happy</string>
        <string>Rain</string>
    </array>

NSString*StringsFromPList=[[NSBundle mainBundle]bundlePath]；
NSString*itemPositionPlistLocation=[StringsFromplistStringByAppendingPathComponent:@“Words.plist”]；
_myDictionary=[[NSDictionary alloc]initWithContentsOfFile:itemPositionPlistLocation]；
NSArray*items=[\u myDictionary objectForKey:@“Root”]；

您没有说实际的问题是什么。问题是什么？这并不会使所有的容器和叶子都是可变的，而NSPropertyListSerialization技术会。
 NSString *StringsFromPList = [[NSBundle mainBundle] bundlePath];
 NSString *itemPositionPlistLocation = [StringsFromPList stringByAppendingPathComponent:@"Words.plist"];
 _myDictionary= [[NSDictionary alloc] initWithContentsOfFile:itemPositionPlistLocation];
NSArray * items = [_myDictionary objectForKey:@"Root"];


<plist version="1.0">
<dict>
<key>Root</key>
    <array>
        <string>Happy</string>
        <string>Rain</string>
    </array>
