NSTextField设置光标颜色

自定义TextField,要修改光标颜色，但是没有iOS textfield类似的tintColor属性，所以需要通过重载方法，修改光标颜色，具体的方法如下:

///修改textfield的光标颜色方法

-(BOOL) becomeFirstResponder

{

    BOOL  success = [super becomeFirstResponder];

    if( success )

    {

        // Strictly spoken, NSText (which currentEditor returns) doesn't

        // implement setInsertionPointColor:, but it's an NSTextView in practice.

        // But let's be paranoid, better show an invisible black-on-black cursor

        // than crash.

        NSTextView* textField = (NSTextView*) [self currentEditor];

        if( [textField respondsToSelector:@selector(setInsertionPointColor:)] )

        {

            NSColor*tintCor=Cor_Title;

            [textField setInsertionPointColor: tintCor];

        }

    }

    return success;

}
