在UITableView中查看plist数据

Question

事情是这样的。我希望将每个对象显示到tableview，而不是它在subs下，所以在这种情况下。 123。 我似乎无法弄清楚如何显示那一项...... 也。它保存plist的方式现在它覆盖了plist似乎。因为每次我添加它都是新鲜的 我在网上跟随数字折磨，这里堆栈溢出。但似乎没有人接近我想做的事。

MainTableViewController.h

{
NSMutableDictionary *arrayD;
}

MainTableViewController.m

 - (void)viewDidLoad
{
[super viewDidLoad];


// Property List.plist code
//Gets paths from root direcory.
NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
//Get documents path.
NSString *documentsPath = [paths objectAtIndex:0];

//Get the path to our PList file.
NSString *plistPath = [documentsPath stringByAppendingPathComponent:@"Servers.plist"];

//Check to see if Property List.plist exists in documents.
if (![[NSFileManager defaultManager] fileExistsAtPath:plistPath]){
    [[NSFileManager defaultManager]copyItemAtPath:[[NSBundle mainBundle]pathForResource:@"Servers" ofType:@"plist"] toPath:plistPath error:nil];
    //If not in documents, get property list from main bundle.
//        plistPath = [[NSBundle mainBundle] pathForResource:@"Servers" ofType:@"plist"];

}

//Read property list into memory as an NSData object.
NSData *plistXML = [[NSFileManager defaultManager] contentsAtPath:plistPath];

NSString *errorDesc = nil;

NSPropertyListFormat format;

//convert static property list into dictionary object.
NSDictionary *temp = (NSDictionary *)[NSPropertyListSerialization propertyListFromData:plistXML mutabilityOption:NSPropertyListMutableContainersAndLeaves format:&format errorDescription:&errorDesc];

    if (!temp){
        NSLog(@"Error reading plist: %@, format: %d", errorDesc, format);
            }

    //Display values.
NSMutableDictionary *dictinoary =[[NSMutableDictionary alloc] initWithContentsOfFile:plistPath];

tableData = [dictinoary objectForKey:@"Hostname"];
NSLog(@"Count: %i", [arrayD count]);

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [tableData count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:    (NSIndexPath *)indexPath

    {
    static NSString *cellIdentifier = @"Hostname";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

if (cell == nil) {

        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];

}

cell.textLabel.text = [tableData objectAtIndex:indexPath.row];

return cell;

}

AddServerViewController.m

    - (IBAction)SaveData:(id)sender {
//Get paths from root direcory.
NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
//Get documents path.
NSString *documentsPath = [paths objectAtIndex:0];

//Get the path to our PList file.
NSString *plistPath = [documentsPath stringByAppendingPathComponent:@"Servers.plist"];

//Set the variables to the values in the text fields.
hostName = hostEntered.text;
portNumber = portEntered.text;
userName = userNameEntered.text;
passWord = passWordEntered.text;

NSMutableDictionary *rootObj = [NSMutableDictionary dictionaryWithCapacity:4];
NSMutableDictionary *data;
data = [NSMutableDictionary dictionaryWithObjects:[NSArray arrayWithObjects: hostName, portNumber, userName, passWord, nil]                                      forKeys:[NSArray arrayWithObjects:@"Hostname", @"Port", @"Username", @"Password", nil]];
[rootObj setObject:data forKey:hostName];


NSString *error = nil;

//Create NSData from dictionary.
NSData *plistData = [NSPropertyListSerialization dataFromPropertyList:rootObj format:NSPropertyListXMLFormat_v1_0 errorDescription:&error];

//Check is plistData exists.
if(plistData){

    //Write plistData to our Properity List.plist file.
    [plistData writeToFile:plistPath atomically:YES];

}
else{
    NSLog(@"Error in saveData: %@", error);
}

}

每个字典都有allKeys方法，该方法返回一个包含...所有键的数组。 如果你按照彼得所说，然后你就可以用allKeys填充你的tableView

Answer 2

如果我误解了您的问题，请原谅我，但在重新创建您的plist之后完成了以下操作：

NSString *path = [[NSBundle mainBundle] pathForResource:@"Sample List" ofType:@"plist"];
NSDictionary *plistDict = [NSDictionary dictionaryWithContentsOfFile:path];

NSLog(@"Plist dict %@", [plistDict objectForKey:@"123"]);

那会输出：

Plist dict {
    Hostname = 123;
    Password = 123;
    Port = 123;
    Username = 123;
}

那是你在寻找什么？如果没有，生病需要更多关于你正在寻找的细节。
