【问题描述】：

我有一个 NSCollectionView 可以像这样读取数据：

    self.contents = @[
                  @@"itemTitle":@"Product 1",
                    @"itemPrice":@"$20.90",
                    @"itemImage":@"PastedGraphic-1.png",

                  @@"itemTitle":@"Product 2",
                    @"itemPrice":@"$10.90",
                    @"itemImage":@"PastedGraphic-3.png",

                  @@"itemTitle":@"Product 3",
                    @"itemPrice":@"$9810.90",
                    @"itemImage":@"PastedGraphic-4.png",

                  @@"itemTitle":@"Product 4",
                    @"itemPrice":@"$100.90",
                    @"itemImage":@"PastedGraphic-5.png",

                  @@"itemTitle":@"Product 5",
                    @"itemPrice":@"$109.19",
                    @"itemImage":@"PastedGraphic-1.png",

                  @@"itemTitle":@"Product 6",
                    @"itemPrice":@"$910.90",
                    @"itemImage":@"PastedGraphic-6.png",

                  @@"itemTitle":@"Product 7",
                    @"itemPrice":@"$632.90",
                    @"itemImage":@"PastedGraphic-7.png",

                  ];

我的问题是，我怎样才能把这段代码变成一个plist文件，这样我就可以使用这段代码把plist文件的数据放到NSCollectionView中：

NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"legue" ofType:@"plist"];
self.contents = [[NSArray alloc] initWithContentsOfFile:plistPath];

【问题讨论】：

既然已经这样写了，你可以在Desktop中使用writeToFile:（例如）来创建一个plist文件，然后使用它。

【参考方案1】：

NSString *filename = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)lastObject];
// your plist path
NSString *path = [filename stringByAppendingPathComponent:@"legue.plist"];
[contents writeToFile:path atomically:YES];
// test it
NSString *str = [[NSBundle mainBundle]pathForResource:@"legue.plist" ofType:nil];
NSLog(@"%@",str); // str = nil; 

所以你应该创建一个新的plist文件，然后你可以使用[NSBundle mainBundle]。

【参考方案2】：

您可以使用以下函数（objective-C）来创建plist文件：

+ (void) writeToPlist 
    NSArray* contents = @[
                          @@"itemTitle":@"Product 1",
                            @"itemPrice":@"$20.90",
                            @"itemImage":@"PastedGraphic-1.png",

                          @@"itemTitle":@"Product 2",
                            @"itemPrice":@"$10.90",
                            @"itemImage":@"PastedGraphic-3.png",

                          @@"itemTitle":@"Product 3",
                            @"itemPrice":@"$9810.90",
                            @"itemImage":@"PastedGraphic-4.png",

                          @@"itemTitle":@"Product 4",
                            @"itemPrice":@"$100.90",
                            @"itemImage":@"PastedGraphic-5.png",

                          @@"itemTitle":@"Product 5",
                            @"itemPrice":@"$109.19",
                            @"itemImage":@"PastedGraphic-1.png",

                          @@"itemTitle":@"Product 6",
                            @"itemPrice":@"$910.90",
                            @"itemImage":@"PastedGraphic-6.png",

                          @@"itemTitle":@"Product 7",
                            @"itemPrice":@"$632.90",
                            @"itemImage":@"PastedGraphic-7.png",

                          ];

    NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory,

                                                         NSUserDomainMask, YES);
    NSString *documentsDirectoryPath = [paths objectAtIndex:0];
    NSString *filePath = [documentsDirectoryPath
                          stringByAppendingPathComponent:@"legue.plist"];

    [contents writeToFile:filePath atomically: YES];

【参考方案3】：

您可以创建一个新的 plist 文件并设计您的 plist 如下图：
