二,UIPickerView 与UIAlertViewController结合

---

typedef void(^PickerViewDidSelectedBlcok) (NSInteger component, NSInteger row);
@property (nonatomic, strong) UIPickerView * pickerView;
/**
 *  UIPickerView 与 UIAlertViewController 结合
 *
 *  @param title alertViewController's title
 *
 *  @param array pickerView's dataSources
 *
 *  @param style alertViewController's style
 */
+ (LCAlertViewController *)LC_alertControllerWithTitle:(NSString *)title dataArray:(NSArray *)array preferredStyle:(LCAlertViewControllerStyle)style;

- (void)LC_addAction:(UIAlertAction *)action withPickerBlock:(PickerViewDidSelectedBlcok)block;

---

***三,UIView (:UIImageView,UILable......)与UIAlertViewController结合 ***

---

---

自定义view的加载 是计算了 添加空格的多少. 所以坐标不准确. 但在实际项目中,只要仔细调整一下位置, 都是可以呈现出完美效果的.

---

typedef void(^CustomViewCallBackBlcok) (NSString * callBackString);
typedef void(^FixedWidthBlcok) (CGFloat customViewWidth);
@property (nonatomic, copy) CustomViewCallBackBlcok callBackBlock;
/**
 *  自定义View 警告 此处的view的坐标高度是 用空格的多少代替.  坐标在实际项目中需要仔细调整
 *  CustomViewCallBackBlcok 的作用 看实际的需求
 *
 *  @param title alertViewController's title
 *
 *  @param view  customView
 *
 *  @param style alertViewController's style
 *
 *  @param block 返回的是系统固定 alertViewController的宽度
 */
+ (LCAlertViewController *)LC_alertControllerWithTitle:(NSString *)title customView:(UIView *)view preferredStyle:(LCAlertViewControllerStyle)style customWidth:(FixedWidthBlcok)block;

- (void)LC_addAction:(UIAlertAction *)action withCustomBlock:(CustomViewCallBackBlcok)block;

---

***注意: ***

---

---

由于使用的是系统的样式与动画效果, 那么LCAlertViewController的宽度和系统的保持相等
LCAlertViewControllerStyleAlert :
宽度为 270;

LCAlertViewControllerStyleActionSheet:
iOS12.x版本 宽度为self.view.frame.size.width-16
iOS12.0以下 宽度为self.view.frame.size.width-20
