Ios 将UISegmentedControl添加到UINavigationController'；工具栏

正在尝试将

UISegmentedControl

添加到

UINavigationController

的工具栏中

-(void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    self.navigationController.toolbarHidden = FALSE;

    UIBarButtonItem *test1 = [[UIBarButtonItem alloc] initWithTitle:@"Groups"
                                                                     style:UIBarButtonItemStyleBordered
                                                                    target:self
                                                                    action:@selector(done)];

    UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:@[@"Groups", @"Regions", @"Objects"]];
    segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;

    [self setToolbarItems:[NSArray arrayWithObjects:test1, segmentedControl, nil]];
}

这会导致以下错误：

-[UISegmentedControl view]: unrecognized selector sent to instance 0x295623c0
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UISegmentedControl view]: unrecognized selector sent to instance 0x295623c0'

如果我省略了

UISegmentedControl

，它可以正常加载

我做错了什么？

您需要用类似于

[[uibarbuttoneim alloc]initWithCustomView:segmentedControl]]的东西将UISegmentedControl包装在uibarbuttoneim中。

就是这样做的！请注意，重复的问题并不完全相同，但答案是相同的。
