objective-c - 无法获取导航栏左侧的 Segmented 控件

Question

我正在尝试以编程方式将 UISegementedControl 添加到导航栏的左侧。我可以通过将控件设置为 titleView 使其显示在中间，如下所示。以下是我拥有的代码

NSArray *buttonNames = [NSArray arrayWithObjects:@"One", @"Two", nil];
UISegmentedControl* segmentedControl = [[UISegmentedControl alloc]
segmentedControl.segmentedControlStyle =  UISegmentedControlStyleBar;

// instead of the following I would like to move to left side of the nav bar
self.navigationItem.titleView = segmentedControl;

任何帮助表示赞赏。

Answer 1

你有没有尝试过

[[UIBarButtonItem alloc] initWithCustomView:...]

?

更准确地说，也许像

UIBarButtonItem* item = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
self.navigationItem.leftBarButtonItem = item;
[item release];
