Hi,

I want NSTextView to scroll to one specific position after opened one text file (some kind like a bookmark).

Following is my code:

[textView setString:contentString];

NSNumber *scrollerPosition = [bookmarks objectForKey:filePath]; if (scrollerPosition) { float maxPosition = NSMaxY([[scrollView documentView] frame]) - NSHeight([[scrollView contentView] bounds]); if ([scrollerPosition floatValue] < maxPosition) { NSPoint newPosition = NSMakePoint(0.0, [scrollerPosition floatValue]); [[scrollView documentView] scrollPoint:newPosition]; } }

I found the value of "maxPosition" always be 0.0 when upper code be invoked every first time, so I think the "setString" method of NSTextView is an async method, the size of scrollView may not be changed immediately after "setString" be invoked.

Then I tried to use

[textView performSelectorOnMainThread:@selector(setString) withObject:contentString waitUntilDone:YES]

instead of

[textView setString:contentString]

But it still won't work..... What should I do now?
