iPhone中如何从Application Bundle中读取文件

首先必须将文件加入Xcode工程的Resources目录。然后可以如下访问文件，假设文件为MyFile.txt：

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"MyFile" ofType:@"txt"];   NSData *myData = [NSData dataWithContentsOfFile:filePath];   if (myData) {       // do something useful   } 

?

?一段将help文本文件读入UIWebView的完整示例：

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"HelpDoc" ofType:@"htm"];   NSData *htmlData = [NSData dataWithContentsOfFile:filePath];   if (htmlData) {       [webView loadData:htmlData MIMEType:@"text/html" textEncodingName:@"UTF-8" baseURL:[NSURL URLWithString:@"http://iphoneincubator.com"]];   } 

?

如果想将文件读入字符串，则可以用UITextView显示，例如：

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"important" ofType:@"txt"];if (filePath) {NSString *myText = [NSString stringWithContentsOfFile:filePath];if (myText) {textView.text= myText;}}
