How to make NSTextField use custom subclass of NSTextFieldCell?

问题

I've been looking for a solution to make my NSTextField bottom-aligned and I've found this and adjusted it for my needs. So now I have this custom NSTextFieldCell but how do I tell my NSTextFields to use this class (programmatically)?

回答1:

Have you tried setCell: method of the NSControl class?

- (void)setCell:(NSCell *)aCell

回答2:

Since you ask how to do it programmatically, you can also use the setCellClass: method on your NSTextField subclass. Call it in the load or initialize class methods:

+(void)load
{
    [self setCellClass:[MyTextFieldCell class]];
}

It will not have any bearing on your text fields defined in Interface Builder, as the text field cell set there takes precedence.
