使用NSURL访问本地文件 [英] Accessing Local file using NSURL

问题描述

我正在尝试访问资源目录中的XML文件存储。我正在使用NSURL使用NSURLConnection访问此文件（此文件将来将被替换为远程服务）。

I am trying to access an XML file store in the resources directory. I am using NSURL to access this file using NSURLConnection( this file is going to be swapped out for a remote service in the future).

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL 
URLWithString:@"file:///XMLTest.xml"] 
cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];

NSURLConnection *connection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
if (connection) {
    // Create the NSMutableData to hold the received data.
    // receivedData is an instance variable declared elsewhere.
    response = [[NSMutableData data] retain];
} else {
    NSLog(@"Could not create connection");
}

启动连接的类实现了NSURLConnection方法：

The class that starts the connection implements the NSURLConnection methods:

connection:willCacheResponse: 
connection:didReceiveData: 
connectionDidFinishLoading: 
connectionDidFinishLoading:

一旦我启动它，模拟器就会死掉，没有消息打印到控制台上，所以我不知道在哪里看。任何想法，或者我只是这样做完全错了？

Once I launch this the simulator dies, no messages are printed to the console so I am at a loss for where to look. Any ideas, or am I just doing this completely wrong?

推荐答案

这也有效：

NSString *path = [[NSBundle mainBundle] pathForResource:@"XMLTest" ofType:@"xml"];

希望这有帮助！
