Iphone在没有界面构建器的情况下创建uibarbutton

Question

我想创建没有界面建设者的uibarbutton =(白色代码),这个按钮是风格相机请帮助我

Answer 1

Objective-C的:

UIBarButtonItem* cameraBarButtonItem = 
     [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera
     target:self action:@selector(myCameraAction)];

迅速:

let cameraBarButtonItem = UIBarButtonItem(barButtonSystemItem: .Camera, target: self, action: "myCameraAction")

这将创建一个带有摄像头系统项图标的UIBarButtonItem.
