Iphone 水平实现UIPickerView？
Iphone 水平实现UIPickerView？,iphone,xcode,uipickerview,Iphone,Xcode,Uipickerview,UIPickerView的默认滚动设置设置为垂直。是否可以水平实施UIPickerView 如果是这样的话，你能给我看一个样品或者告诉我在哪里可以找到有用的文档吗？你可以使用。。UIPickerView的自定义、可配置的水平版本（基于旋转的轮子或老虎机隐喻），包含一个表单元实现。最初用于压缩多选项设置所需的空间/行。在.h文件中 #import <UIKit/UIKit.h> @interface ViewController : UIViewController <UIPi
