与plist的奇怪错误 [英] Strange bug with plist

问题描述

当我尝试读取我的plist时，我遇到了一个非常奇怪的错误. 我的列表如下:

I got a very strange bug when I'm trying to read my plist. My plist looks like :

Root (Array)
            Item 0 (Dictionary)
                              title (String)

我想在日志中显示title，所以我做了下面的代码:

I want to display title in the log, so I did the code bellow:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *basePath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
NSString *path = [basePath stringByAppendingPathComponent:@"data.plist"];
NSMutableDictionary *dict = [[NSDictionary dictionaryWithContentsOfFile:path] mutableCopy];

NSLog(@"%@", [dict objectForKey:@"title"]);

NSLog(@"Path to plist: %@", path);

使用此代码，NSLog(@"%@", [dict objectForKey:@"title"]);等于"(null)" ...

With this code, NSLog(@"%@", [dict objectForKey:@"title"]); is equal to "(null)"...

我的plist位于应用程序的documents文件夹中，而path的日志返回指向我的plist的正确路径.

My plist is in my app's documents folder, and the log of path return the good path to my plist.

请帮助我:)

推荐答案

plist的根是一个数组，但是您将其读入字典中，那是行不通的.

The root of your plist is an array but you read it into a dictionary, thats won't work.

您应该:

• 将plist读入数组
• 获取项目0(objectAtIndex:0)->这是一本字典
• 在此词典上，您可以执行objectForKey ...
