AZPickiew是基于UIPickView做的封装，用法相对简单

@interface AZPickView : UIView
@property (nonatomic , strong) NSArray * dataSource;
@property (nonatomic , weak) id delegate;
// PickView的宽，默认是60，如果界面仍然不能显示完全，适当增大。
@property (nonatomic , assign) float pickWidth;
// PickView的高，默认是35，如果不满足，可适当增大
@property (nonatomic ,assign) float rowHeight;
// // 设置初始化时所对应的数据，可为空。
@property (nonatomic ,strong) NSArray * pickInitArray;
// 加载页面
+ (instancetype) loadView;

用法：

#import "ViewController.h"
#import "AZPickView.h"
// 屏幕 SCREEN_WIDTH
#define SCREEN_WIDTH ([[UIScreen mainScreen] bounds].size.width)
//屏幕 SCREEN_HEIGHT
#define SCREEN_HEIGHT ([[UIScreen mainScreen] bounds].size.height)
@interface ViewController ()
@property (nonatomic ,strong) UIButton * currentBtn;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    [self initUI];
}
