nstextview

I've an NSTextView with with several semi-colon separated strings. I need to find on which of those strings the caret has been placed. How could I do that? NSInteger insertionPoint = [[[myTextView selectedRanges] objectAtIndex:0] rangeValue].location; For Swift 4 let insertionPointIndex = myTextView.selectedRanges.first?.rangeValue.location 来源： https://stackoverflow.com/questions/1701129/how-to-find-caret-position-in-an-nstextview

I'm trying to draw text using Core Text functions, with a line spacing that's as close as possible to what it would be if I used NSTextView. Take this font as an example: NSFont *font = [NSFont fontWithName:@"Times New Roman" size:96.0]; The line height of this font, if I would use it in an NSTextView is 111.0. NSLayoutManager *lm = [[NSLayoutManager alloc] init]; NSLog(@"%f", [lm defaultLineHeightForFont:font]); // this is 111.0 Now, if I do the same thing with Core Text, the result is 110.4 (assuming you can calculate the line height by adding the ascent, descent and leading).

I'm using an NSTask to run rsync, and I'd like the status to show up in the text view of a scroll view inside a window. Right now I have this: let pipe = NSPipe() task2.standardOutput = pipe task2.launch() let data = pipe.fileHandleForReading.readDataToEndOfFile() let output: String = NSString(data: data, encoding: NSASCIIStringEncoding)! as String textView.string = output And that get's me the some of the statistics about the transfer, but I'd like to get the output in real time, like what get's printed out when I run the app in Xcode, and put it into the text view. Is there a way to do this?
