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;

	}

}
