Iphone 未加载来自plist的数据

我的代码有问题吗
我想我的问题是'CellForRowatineXpath',我已经在Places.h上将'name'和'info'声明为nsstring。但在plist上,它就像nsarray一样。但是我不知道如何解决这个问题。我认为您在加载数据时遇到了问题 首先,您说您从place.plist获取数据,但在viewDidLoad中,您试图从bnm.plist加载数据 请尝试使用以下代码:
- (void)viewDidLoad
{
[super viewDidLoad];
// Initialize table data
// Find out the path of bnm.plist
NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"bnm" ofType:@"plist"]];
// Load the file content and read the data into arrays
MCWPlaces *placeGO = [MCWPlaces new];
placeGO.name = [dict objectForKey:@"PlaceName"];
placeGO.info = [dict objectForKey:@"PlaceInfo"];
}
您能给我们看一下您的bnm.plist吗?好的,那么您走错了。 使用以下代码并在项目中替换它: bnm.plist
<?xml version="1.0" encoding="UTF-8"?>

文件在哪里?在捆绑包中还是在文档
文件夹中?因为它位于Documents
文件夹中,所以方法–pathForResource:ofType:
不会为它提供路径…@jordon,对不起,实际上plist文件是bnm.plist,我已经插入了plist。当我放置“places=[NSArray arrayWithObject:placeGO];”并运行应用程序时,输出“-[\u NSCFArray IsequalString:]:未识别的选择器发送到实例0x75992e0”,应用程序将在“cell.textLabel.text=place.name;”处中断@乔登,我试过你建议的代码,但都是一样的。我想我的问题是'CellForRowatineXpath',我已经在Places.h上将'name'和'info'声明为nsstring。但在plist上,它就像nsarray一样。但是我不知道如何解决这个问题。请分享你的plist文件的结构。@shhrzl尝试我的第二个答案;)这是工作..非常感谢..从您的代码中,我添加了“-(void)prepareforsgue:(UIStoryboardSegue*)segue sender:(id)sender”以加载PlaceInfo
