LCAlertViewController

一,说明

支持iOS8及以上,适配iPhone和iPad. LCAlertViewController将 UIPickerView和UIAlertViewController结合, 并且添加自定义的View blog地址: https://blog.csdn.net/luochuanAD/article/details/83450748

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;

(iPhone:) 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

(iPad:) LCAlertViewControllerStyleActionSheet:

宽度设置为300
