如何禁用UISegmentedControl？

Question

我有一个 UISegmentedControl，我想要禁用它：

-(void)displayCheckMark
{
    titleSegmentedControl = [[UISegmentedControl alloc] initWithItems:nil];
    [titleSegmentedControl insertSegmentWithImage:[UIImage imageNamed:@"symbolbg.png"] atIndex:0 animated:YES];
    [titleSegmentedControl insertSegmentWithImage:[UIImage imageNamed:@"inwatchlist.png"] atIndex:1 animated:YES];
    [titleSegmentedControl addTarget:self action:@selector(titleBarButtonChanged:)forControlEvents:UIControlEventValueChanged];
    titleSegmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
    titleSegmentedControl.frame = CGRectMake(100,0,100,30);
    titleSegmentedControl.momentary = YES;
    titleSegmentedControl.tintColor = [UIColor blackColor];
    self.navigationItem.titleView = titleSegmentedControl;

    [titleSegmentedControl setWidth:60 forSegmentAtIndex:0];
    [titleSegmentedControl setTitle:symbol forSegmentAtIndex:0];
    [titleSegmentedControl setWidth:30 forSegmentAtIndex:1];
    [titleSegmentedControl setEnabled:NO];
}

我在代码中没有启用它。然而我仍然可以点击它，并且它将执行titleBarButtonChanged的操作：

如何确保它无法被点击？

Answer 1

尝试使用：

- (void)setEnabled:(BOOL)enabled forSegmentAtIndex:(NSUInteger)segment;

或者

titleSegmentedControl.userInteractionEnabled = NO;

在 titleBarButtonChanged:(id)sender 中添加:

if(!sender.enabled) return;
