如何添加plist来打包和修改plist

Question

我有一个plist，我将这个plist复制到我的xcode项目中，但是文件似乎不在捆绑中：

NSDictionary *dict = [[NSBundle mainBundle] infoDictionary];
nslog (@"dict %@",dict);

但是文件plist文件没有显示。问题是，如何将文件添加到项目中，以查看包中的内容？另外，你们中的任何人都知道我如何修改plist并保存更改？

我真的很感激你的帮助

我用的是Xcode 5。

Answer 1

您可以在包中创建一个plist文件，并将其内容修改为：

NSString *bundlePath = [[NSBundle mainBundle]bundlePath]; //Path of your bundle
NSString *path = [bundlePath stringByAppendingPathComponent:@"MyPlist.plist"]; 
NSFileManager *fileManager = [NSFileManager defaultManager];

NSMutableDictionary *data;

if ([fileManager fileExistsAtPath: path]) 
{
    data = [[NSMutableDictionary alloc] initWithContentsOfFile: path];  // if file exist at path initialise your dictionary with its data
}
else
{
    // If the file doesn’t exist, create an empty dictionary
    data = [[NSMutableDictionary alloc] init];
}

//To insert the data into the plist
int value = 5;
[data setObject:[NSNumber numberWithInt:value] forKey:@"value"];
[data writeToFile: path atomically:YES];
[data release];

//To retrieve the data from the plist
NSMutableDictionary *savedData = [[NSMutableDictionary alloc] initWithContentsOfFile: path];
int savedValue;
savedValue = [[savedData objectForKey:@"value"] intValue];
NSLog(@"%i",savedValue);

Answer 2

infoDictionary将返回Info.plist文件。您应该使用pathForResource:ofType:方法的NSBundle类。

NSString *commonDictionaryPath;
if (commonDictionaryPath = [[NSBundle mainBundle] pathForResource:@"CommonDictionary" ofType:@"plist"])  {
    theDictionary = [[NSDictionary alloc] initWithContentsOfFile:commonDictionaryPath];
}

如何将plist添加到包中？

将plist拖到构建目标的“复制捆绑资源”阶段

修改plist

将plist复制到应用程序的Documents文件夹，并在那里修改它。

这应该能行

     NSString*pListDictPath = [[NSBundle mainBundle] pathForResource:@"yourPlistName" ofType:@"plist" inDirectory:@"YourDirectory"];
     if()
     {
            NSDictionary *theDictionary = [[NSDictionary alloc] initWithContentsOfFile:pListDictPath ];
     }
