效果圖如下所示：
swift: https://github.com/corin8823/Popover OC: https://github.com/Assuner-Lee/PopoverObjC
使用示例
pod 'PopoverObjC'
#import "ASViewController.h"
#import <PopoverObjC/ASPopover.h>
@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的屬性可在option里設置。
彈出氣泡
- (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
可在某一個視圖或某一個point上彈出內容view
Popover interface #import <UIKit/UIKit.h> #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: 要顯示的內容； fromView: 氣泡從某一個視圖上show; inview: 氣泡繪制在某一個視圖上，一般為delegate window； atPoint: 氣泡從某一點上show; 可先獲取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
