plist 的创建和NSMutableDictionary 的initWithContentsOfFile用法(转)

IOS开发中肯定会用到的。

原文地址如下：（我改了一下标题，这样检索的时候更容易找到）

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 

NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"plist.plist"]; NSFileManager *fileManager = [NSFileManager defaultManager];

if (![fileManager fileExistsAtPath: path]) 
{
    path = [documentsDirectory stringByAppendingPathComponent: [NSString stringWithFormat: @"plist.plist"] ];
}

NSMutableDictionary *data = [[NSMutableDictionary alloc] initWithContentsOfFile: path];
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];

}

 

int value = 5;
[data setObject:[NSNumber numberWithInt:value] forKey:@"value"];
[data writeToFile: path atomically:YES];
[data release];

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