Question

I would like to add an NSTextView object to my app and add an action that opens a .txt file located in the app bundle in the textView. Also – I would like to have the option to edit and save the edited doc without renaming it. So standard save, not save as.

What’s the best way to handle this?

Answer 1

Use NSString to load the file and put it in your text view:

NSTextView *textView; //your NSTextView object
NSError *err = nil;
NSString *path = [[NSBundle mainBundle] pathForResource:@"EditableFile" ofType:@"txt"];
NSString *contents = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:&err];
if(!contents) {
    //handle error
}
[textView setString:contents];

Saving is just the opposite. Get the string and write it to the file:

NSTextView *textView; //your NSTextView object
NSError *err = nil;
NSString *path = [[NSBundle mainBundle] pathForResource:@"EditableFile" ofType:@"txt"];
NSString *contents = [textView string];
if(![contents writeToFile:path atomically:YES encoding:NSUTF8StringEncoding error:&err]) {
    //handle error
}
