我尝试了很多东西,无法让它发挥作用......
[[NSUserDefaults standardUserDefaults] setObject:[my_popup_button selectedItem] forKey:@"selected"];
不起作用,有什么建议吗?
答案 0 :(得分:3)
这是我刚刚创建的一个最小例子:
AppDelegate.h
#import <Cocoa/Cocoa.h>
@interface AppDelegate : NSObject <NSApplicationDelegate>
@property (assign) IBOutlet NSWindow *window;
@property (assign) IBOutlet NSPopUpButton *popupButton;
- (IBAction)onPopupBtnSelectedItemChanged:(id)sender;
@end
AppDelegate.m
#import "AppDelegate.h"
@implementation AppDelegate
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
[self.popupButton selectItemAtIndex:[[NSUserDefaults standardUserDefaults] integerForKey:@"selectedItemIndex"]];
}
- (IBAction)onPopupBtnSelectedItemChanged:(id)sender
{
[[NSUserDefaults standardUserDefaults] setInteger:self.popupButton.indexOfSelectedItem
forKey:@"selectedItemIndex"];
}
尝试过它就像魅力一样。 最好,
