objective-c - Mac OSX 如何添加 plist 来捆绑和修改 plist

Question

我有一个 plist，我将 plist 复制到我的 xcode 项目，但似乎文件不在包中:

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

但是文件 plist 文件没有显示。问题，我怎样才能以在包中看到的方式将文件添加到项目中？还有你们知道如何修改 plist 并保存更改吗？

非常感谢你的帮助

附言我正在使用 Xcode 5。

您可以在您的包中创建一个 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);
