Change direction of disclosure triangle
How can I change the direction of the disclosure triangle programmatically? In Interface Builder it's possible by changing the value "Control -> Layout" from "Left to Right" or "Right to Left".
I made a diff of a NIB file. The only开发者_Go百科 change was NSCellFlags2
.
Is this documented anywhere?
The method you’re looking for is -[NSCell setUserInterfaceLayoutDirection:]
. You need to obtain a reference to the corresponding cell and then send it the appropriate message. For example, considering disclosureButton
points to that disclosure button:
[[disclosureButton cell] setUserInterfaceLayoutDirection:NSUserInterfaceLayoutDirectionRightToLeft];
