NSTextField

• 设置光标颜色

#import "MYTextField.h"
@implementation MYTextField

- (void)drawRect:(NSRect)dirtyRect {
    [super drawRect:dirtyRect];
    [(NSTextView*)[self currentEditor] setInsertionPointColor:[NSColor blueColor]];
}

@end

• 去掉选中时蓝色边框

  
  
  

• 设置stringValue时如果为nil，会 Crash，要做判空处理.

textField.stringValue = newAppPath ? newAppPath : @"";
