我们如何在Xcode项目中创建自己的plist文件？ [英] How can we create our own plist file in a Xcode project?

问题描述

我想在我的应用程序中创建UrlPaths.plist文件，还有一个包含4或5个对象的字典。请帮我创建一个plist文件和字典。并且还从该plist文件中读取数据。

I want to create "UrlPaths.plist" file in my Application and also a dictionary with 4 or 5 objects. Please help me create a plist file and dictionary. And also read data from that plist file.

我希望plist将文件添加到资源文件夹，我也想添加Dictionary，那时也不想实用

I want the plist to add the file to resources folder and i want to add Dictionary at that time also.i dont want pragmatical creation of plist but i want reading the data is pragmatically.

推荐答案

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"plist.plist"]; 
NSFileManager *fileManager = [NSFileManager defaultManager];

NSMutableDictionary *data;

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

//To insert the data into the plist
data[@"value"] = @(5);
[data writeToFile: path atomically:YES];
[data release];

//To retrieve the data from the plist
NSMutableDictionary *savedStock = [[NSMutableDictionary alloc] initWithContentsOfFile:path];
int value1;
value1 = [savedStock[@"value"] intValue];
NSLog(@"%i",value1);
[savedStock release];
