先看效果
使用示例
pod 'PopoverObjC'复制代码
#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 {}复制代码
初始化Popover
- (ASPopover *)btnPopover { if (!_btnPopover) { ASPopoverOption *option = [[ASPopoverOption alloc] init]; option.autoAjustDirection = YES; option.preferedType = ASPopoverTypeDown; 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 = YES; option.arrowSize = CGSizeMake(10, 6); option.offset = 3; // vertical offset from original show point, default is 0. option.blackOverlayColor = [UIColor clearColor]; option.sideEdge = 7; option.dismissOnBlackOverlayTap = YES; option.popoverColor = [[UIColor blackColor] colorWithAlphaComponent:0.7]; option.animationIn = 0.4; option.springDamping = 0.5; option.initialSpringVelocity = 1; option.overlayBlur = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight]; //... _itemPopover = [[ASPopover alloc] initWithOption:option]; } return _itemPopover;}复制代码 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]; // above, option has contained offset value; invoke [self show:contentView fromView:fromView inView:keyWindow]; /* other method to show CGPoint orignPoint = [self.itemPopover orignArrowPointWithView:view fromView:itemView]; orignPoint.y += 5; // offset in option has same effect [self.itemPopover show:view atPoint:orignPoint]; */ }}复制代码 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复制代码
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；
