使用“后退”按钮在导航栏中进行UISegmentedControl [英] UISegmentedControl in the Navigation Bar with the Back button

问题描述

我正在以编程方式将 UISegmentedControl 添加到导航栏，其中 titleView 应该是。但是， Apple docs 已提到在 titleView 下，如果leftBarButtonItem不是nil ，则忽略此属性。

I'm adding a UISegmentedControl to the Navigation bar programatically where the titleView should be. But as Apple docs have mentioned under titleView, This property is ignored if leftBarButtonItem is not nil.

但是我想要也有后退按钮。就像他们在自己的图像中说明一样！

But I want to have the back button as well. Like they have illustrated in their own images!

以下是我添加 UISegmentedControl 的代码。

self.navigationItem.leftBarButtonItem = nil;
UISegmentedControl *statFilter = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"Filter_Personnal", @"Filter_Department", @"Filter_Company", nil];
[statFilter setSegmentedControlStyle:UISegmentedControlStyleBar];
self.navigationItem.titleView = statFilter;

还有另一种方法可以添加 UISegmentedControl 还有后退按钮？

Is there another way to add a UISegmentedControl along with the Back button as well?

谢谢。

推荐答案

试试这个

删除这一行---> self.navigationItem.leftBarButtonItem = nil;

Remove this line --- > self.navigationItem.leftBarButtonItem = nil;

添加此项

UISegmentedControl *statFilter = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"Filter_Personnal", @"Filter_Department", @"Filter_Company", nil]];
[statFilter setSegmentedControlStyle:UISegmentedControlStyleBar];
[statFilter sizeToFit];
self.navigationItem.titleView = statFilter;

只有更改是我添加了这一行：

Only change is I have added this line :

[statFilter sizeToFit];

希望这有助于!!!
