Xcode text

What do you mean by "display text"? Do you mean putting something into a text field or text view (these are also usually connected to an outlet)? Can you post some code - what have you done so far?

Typically you would set up an outlet property for the text view, for example:

property myTextView : missing value

...then connect the outlet to the text view (not the scroll view part) in the Interface Editor. Once connected you can use the various NSTextView class (and its parent) methods and put text in the text view by using a statement such as:

myTextView's setString_(finalString)

A timer can be set up when the application is being initialized to repeatedly call your handler, for example:

property refreshTimer: missing value-- so the timer can be manipulated later if desired

--

set refreshTimer to current application's NSTimer's scheduledTimerWithTimeInterval_target_selector_userInfo_repeats_(60, me, "yourHandler", missing value, true)

Your handler declaration didn't get pasted (I'm guessing it doesn't have any passed parameters), so just replace yourHandler with the name of your handler - see the NSTimer Class Reference.

The OSACompile Error means that there is a syntax error in the AppleScript. The Xcode editor doesn't have a compile option like the AppleScript Editor, but you can open a script in the AppleScript Editor by right-clicking on a script file (in the Project Navigator) and choose Open with External Editor. You have a few errors in your script, mainly dealing with your organization (it also looks like an Objective-C piece or two got put in there).

AppleScriptObjC in Xcode does not have an implicit run handler, so you need to make sure your script statements are placed inside a handler - either your own or a delegate handler. Since there is no run handler per se and the application is typically driven by user events (mouse clicks, button presses, etc), you also need a way to start your script (or respond to an event). This can be done by using an IB action handler connected to a button or call a handler when the application starts up, for example from the applicationDidFinishLaunching delegate handler.

I rearranged (and tested) your code using one of my templates - the myTextView property is connected to the text view, and a refresh button (I am guessing that is what you are using) is connected to the doButton_ handler, which gets new information and updates the text view:

A label is a type of text field. The error you are getting tells me that you are using a text field instead of a text view. You mentioned a text view earlier, so I figured you were using one so that you could append new ticker stuff to the existing text by pressing a button to refresh/update. In addition to not having scroll bars, a text field uses a different method to set the text, so if you are planning on expanding your list of tickers or want to be able to scroll back to previous information, a text view might be the object to use.

You can either remove the text field you are using now and replace it with a text view, or stick with using a text field and change my posted code to use that. To use a text field, change the last 4 lines of the doStuff handler to the following (I'll leave changing the name of the variable as an exercise for you):

myTextView's setStringValue_(finalString)

Edit: you'll also need to change the line in the applicationWillFinishLaunching handler to

myTextView's setStringValue_("")

Yes, you should probably just replace the text field stuff you have now with the text view (NSTextView in an NSScrollView) and connect the myTextView property to the text view (not the scroll view). The quick project I set up uses a text view so that when a refresh button is clicked new information is appended to the end of the old - it will handle more text better than a text field will.
