首先必須將文件加入Xcode工程的Resources目錄。然後可以如下訪問文件,假設文件爲MyFile.txt:
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"MyFile" ofType:@"txt"];
NSData *myData = [NSData dataWithContentsOfFile:filePath];
if (myData) {
// do something useful
}
一段將help文本文件讀入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"]];
}
如果想將文件讀入字符串,則可以用UITextView顯示,例如:
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"important" ofType:@"txt"];
if (filePath) {
NSString *myText = [NSString stringWithContentsOfFile:filePath];
if (myText) {
textView.text= myText;
}
}
