UISegmentedControl``崩潰的Xcode

我想提上Navigation ItemUISegmentedControl但它崩潰我的Xcode ..我只是簡單地添加在界面生成器文件中的UISegmentedControl（IB）文件，然後在viewDisAppearUISegmentedControl``崩潰的Xcode

IBOutlet UISegmentedControl *segmentedControl;

self.navigationItem.titleView=segmentedControl;

這只是我崩潰的xcode與錯誤

爲什麼這個錯誤是未來

你在哪裏把分割控制在界面生成器？難道你不能直接在nib文件中使分割控件成爲標題視圖嗎？ – architectpianist 2013-03-12 12:19:52

通常在視圖中...但如何使直接在筆尖文件中的標題視圖的分段控制 – Christien 2013-03-12 12:22:13

爲什麼你把段放在XIB中，然後在代碼中給出？相反，你可以分配init的segmentedControl通過代碼，然後嘗試.. – 2013-03-12 12:22:43

UISegmentedControl * seg1 = [[UISegmentedControl alloc] 
    initWithItems:[NSArray arrayWithObjects:@"von mir", @"alle", nil]]; 
[seg1 setSegmentedControlStyle:UISegmentedControlStyleBar]; 
self.navigationItem.titleView = seg1;
