Question

我是菜鸟，我无法弄清楚如何将我的应用数据移植到plist，以便我可以将它放在服务器上。

我遵循了一个在线教程，它运行良好，但我无法理解应用程序是如何实际制作的，以便我可以远程更新它。

我已经尝试了很多书籍和在线资源，并联系了lynda.com教练，但仍然没有在6个月内解决这个问题。

这让我疯了。我认为应用程序的设置方式令我感到困惑。无论如何，我在最后的努力中转向大师寻求帮助。

**第一篇文章，所以我会尝试包含我认为相关的所有内容，但如果需要更多信息，请告诉我**

基本上，使用故事板，我有一个桌面视图，可以转到另一个视图，根据所选的单元格显示图像和更多信息。所以我认为我需要的是一个包含一系列字典的plist。

这是原始代码，不使用plist：

//Data.h

#import <Foundation/Foundation.h>

@interface Data : NSObject

@property (nonatomic, strong) NSString *name;
@property (nonatomic, strong) NSString *filename;
@property (nonatomic, strong) NSString *notes;

@end

// Data.m #import“Data.h”

@implementation Data


@synthesize name,filename,notes;

@end


//  TableViewController.h


#import <UIKit/UIKit.h>
#import "Data.h"
#import "DisplayViewController.h"



@interface TableViewController : UITableViewController

@end

/
//  TableViewController.m
//

#import "TableViewController.h"

@interface TableViewController ()

@end

@implementation TableViewController

NSMutableArray *subjects;

-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    if ([segue.identifier isEqualToString:@"ShowData"]  ){

        DisplayViewController *dvc = [segue destinationViewController];
        NSIndexPath *path = [self.tableView indexPathForSelectedRow];
        Data *c = [subjects objectAtIndex:path.row];
        [dvc setCurrentData:c];
    }
}


- (id)initWithStyle:(UITableViewStyle)style
{
    self = [super initWithStyle:style];
    if (self) {
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    subjects = [[NSMutableArray alloc] init];

    Data *object = [[Data alloc] init];

    [object setName:@"testname1"];
        [object setFilename:@"testname1.png"];
        [object setNotes:@"detail description for test name 1"];
    [subjects addObject:object];

    object = [[Data alloc] init];
    [object setName:@"testname2"];
    [object setFilename:@"testname2.png"];
    [object setNotes:@"detail description for test name 2"];
    [subjects addObject:object];

    object = [[Data alloc] init];
    [object setName:@"testname3"];
    [object setFilename:@"testname3.png.png"];
    [object setNotes:@"detail description for test name 3"];
    [subjects addObject:object];

}


- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{

    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

    return [subjects count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"DataCell1";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    // Configure the cell...

    Data *current = [subjects objectAtIndex:indexPath.row];
    [cell.textLabel setText:[current name]];


    return cell;
}

#pragma mark - Table view delegate

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
   }

@end


//  DisplayViewController.h


#import <UIKit/UIKit.h>
#import "Data.h"
#import "InfoViewController.h"

@interface DisplayViewController : UIViewController

@property (strong, nonatomic) Data *currentData;
@property (weak, nonatomic) IBOutlet UIImageView *currentImage;

@end

//  DisplayViewController.m

#import "DisplayViewController.h"

@interface DisplayViewController ()

@end

@implementation DisplayViewController

@synthesize currentData;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    UIImage *image  = [UIImage imageNamed:[currentData filename]];

    [self.currentImage setImage:image];
    [self setTitle:[currentData name]];
}

-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender   {

    InfoViewController *ivc = [segue destinationViewController];
    [ivc setCurrentData:[self currentData]];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
