简单好用可任意定制的iOS Popover气泡

先看效果

popover

swift: https://github.com/corin8823/Popover
OC: https://github.com/Assuner-Lee/PopoverObjC

使用示例

pod 'PopoverObjC'

#import "ASViewController.h"
#import 

@interface ASViewController ()

@property (weak, nonatomic) IBOutlet UIButton *btn;
@property (nonatomic, strong) ASPopover *btnPopover;
@property (nonatomic, strong) ASPopover *itemPopover;

@end

@implementation ASViewController

- (void)viewDidLoad {
  [super viewDidLoad];
  [self.btn addTarget:self action:@selector(clickBtn:) forControlEvents:UIControlEventTouchUpInside];
  
  self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"item" style:UIBarButtonItemStylePlain target:self action:@selector(clickItem:)];
}

- (void)didReceiveMemoryWarning {
}

初始化Popover

- (ASPopover *)btnPopover {
  if (!_btnPopover) {
    ASPopoverOption *option = [[ASPopoverOption alloc] init];
    option.popoverType = ASPopoverTypeUp;
    option.autoAjustDirection = NO;
    option.arrowSize = CGSizeMake(9, 6);
    option.blackOverlayColor = [UIColor clearColor];
    option.popoverColor = [UIColor lightGrayColor];
    option.dismissOnBlackOverlayTap = YES;
    option.animationIn = 0.5;
    //...
    
    _btnPopover = [[ASPopover alloc] initWithOption:option];
  }
  return _btnPopover;
}


- (ASPopover *)itemPopover {
  if (!_itemPopover) {
    ASPopoverOption *option = [[ASPopoverOption alloc] init];
    option.autoAjustDirection = NO;
    option.arrowSize = CGSizeMake(10, 6);
    option.blackOverlayColor = [UIColor clearColor];
    option.sideEdge = 7;
    option.dismissOnBlackOverlayTap = YES;
    option.popoverColor = [[UIColor blackColor] colorWithAlphaComponent:0.7];
    option.autoAjustDirection = YES;
    option.animationIn = 0.4;
    option.springDamping = 0.5;
    option.initialSpringVelocity = 1;
    option.overlayBlur = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];
    //...
    
    _itemPopover = [[ASPopover alloc] initWithOption:option];
  }
  return _itemPopover;
}

popover的属性可在option里设置。

弹出气泡

- (void)clickBtn:(id)sender {
  UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width - 50, 40)];
  [self.btnPopover show:view fromView:self.btn];  // in delegate window
}

- (void)clickItem:(id)sender {
  UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 200)];
  UIView *itemView = [self.navigationItem.rightBarButtonItem valueForKey:@"view"]; // you should use custom view in item;
  if (itemView) {
//    [self.itemPopover show:view fromView:itemView];
    CGPoint originPoint = [self.itemPopover originArrowPointWithView:view fromView:itemView];
    originPoint.y += 5;
    [self.itemPopover show:view atPoint:originPoint];
  }
}
@end

可在某一个视图或某一个point上弹出内容view

Popover interface

#import 
#import "ASPopoverOption.h"

typedef void (^ASPopoverBlock)(void);

@interface ASPopover : UIView

@property (nonatomic, copy) ASPopoverBlock willShowHandler;
@property (nonatomic, copy) ASPopoverBlock willDismissHandler;
@property (nonatomic, copy) ASPopoverBlock didShowHandler;
@property (nonatomic, copy) ASPopoverBlock didDismissHandler;

@property (nonatomic, strong) ASPopoverOption *option;

- (instancetype)initWithOption:(ASPopoverOption *)option;
- (void)dismiss;

- (void)show:(UIView *)contentView fromView:(UIView *)fromView;
- (void)show:(UIView *)contentView fromView:(UIView *)fromView inView:(UIView *)inView;
- (void)show:(UIView *)contentView atPoint:(CGPoint)point;
- (void)show:(UIView *)contentView atPoint:(CGPoint)point inView:(UIView *)inView;

- (CGPoint)originArrowPointWithView:(UIView *)contentView fromView:(UIView *)fromView;
- (CGPoint)arrowPointWithView:(UIView *)contentView fromView:(UIView *)fromView inView:(UIView *)inView popoverType:(ASPopoverType)type;
@end

contentView: 要显示的内容；
fromView: 气泡从某一个视图上show;
inview: 气泡绘制在某一个视图上，一般为delegate window；
atPoint: 气泡从某一点上show; 可先获取originPoint, 偏移；

PopoverOption Interface

typedef NS_ENUM(NSInteger, ASPopoverType) {
  ASPopoverTypeUp = 0,
  ASPopoverTypeDown,
};

@interface ASPopoverOption : NSObject

@property (nonatomic, assign) CGSize arrowSize;
@property (nonatomic, assign) NSTimeInterval animationIn; // if 0, no animation
@property (nonatomic, assign) NSTimeInterval animationOut;
@property (nonatomic, assign) CGFloat cornerRadius;
@property (nonatomic, assign) CGFloat sideEdge;
@property (nonatomic, strong) UIColor *blackOverlayColor;
@property (nonatomic, strong) UIBlurEffect *overlayBlur;
@property (nonatomic, strong) UIColor *popoverColor;
@property (nonatomic, assign) BOOL dismissOnBlackOverlayTap;
@property (nonatomic, assign) BOOL showBlackOverlay;
@property (nonatomic, assign) CGFloat springDamping;
@property (nonatomic, assign) CGFloat initialSpringVelocity;
@property (nonatomic, assign) ASPopoverType popoverType;
@property (nonatomic, assign) BOOL highlightFromView;
@property (nonatomic, assign) CGFloat highlightCornerRadius;
@property (nonatomic, assign) BOOL autoAjustDirection; // down preferred, effect just in view not at point

@end
