iOS 微信右上角下拉菜单效果之CMPopTipView,各种角度各种位置

    早之前在项目中写了一个类似微信右上角下拉的菜单封装,但是是写死的,当时根本

有考虑到去其他地方弹出这个东西,虽然看起来弹个窗出来很简单,但是你位子不确

定之后弹出来是有点麻烦的,反正我总是觉得,我们能想到的,老外早就想到了,多给自己弄点工具库,多看看源码,指不定哪天我也搞出一个库来iOS 微信右上角下拉菜单效果之CMPopTipView,各种角度各种位置iOS 微信右上角下拉菜单效果之CMPopTipView,各种角度各种位置,世界

上有项目经理这种东西,那就没有什么需求是不可能的,各位手头上多准备点工具还是非常有必要的。

先看图:

哎呦,这妹子不错吧iOS 微信右上角下拉菜单效果之CMPopTipView,各种角度各种位置


Demo介绍

首先,新建一个工程,把Button创建出来,点击事件加上,先看属性

@interface ViewController () <CMPopTipViewDelegate,UICollectionViewDelegate,UICollectionViewDataSource,UICollectionViewDelegateFlowLayout,UITableViewDelegate,UITableViewDataSource>

@property (nonatomic,strong) CMPopTipView *roundRectButtonPopTipView;

@property (nonatomic,strong) NSMutableArray       *dataSource; //!< collectionView的数据源
@property (nonatomic,strong) GroupList            *list;       //!< 请求回来的数据
@property (nonatomic,strong) UICollectionView     *collectionView;
@property (nonatomic,strong) UIImageView          *imageView;
@property (nonatomic,strong) UIImageView          *imageView1;
@property (weak,  nonatomic) IBOutlet UILabel     *middleLabel;
@property (nonatomic,strong) NSMutableArray	      *visiblePopTipViews; //!< 可见的PopView
@property (nonatomic,strong) id				      currentPopTipViewTarget;  //!< 当前的按钮
@property (nonatomic,strong) UITableView          *tableView;
@property (nonatomic,strong) NSMutableArray       *tableDataSource;
@property (nonatomic,strong) UIButton             *gotoCartButton; // NVBar的按钮

@end


所有非NavigationItemButton的点击事件

注:该方法可以获取到已加载数据的CollectionView的理论高度

height  = self.collectionView.collectionViewLayout.collectionViewContentSize.height;


- (IBAction)click:(UIButton *)sender
{
    // 先dismiss之前的所有popView
    [self dismissAllPopTipViews];
    // 当检测到是和之前一样的按钮,由于已经清空,那么不进行任何操作,也把容器清空,下次再点就可以下一波操作了
    if (sender == self.currentPopTipViewTarget) {
        self.currentPopTipViewTarget = nil;
    }
    else
    {
        // 没有pop的时候,先计算出collectionView的高度
        CGFloat height;
        if (sender.tag == 1000) {
            self.dataSource = [[NSMutableArray alloc] initWithArray:self.list.data.role];
            [self.collectionView reloadData];
            
        }
        else if (sender.tag == 1003)
        {
            self.dataSource = [[NSMutableArray alloc] initWithArray:self.list.data.list];
            [self.collectionView reloadData];
            
        }
        // 算高度
        height  = self.collectionView.collectionViewLayout.collectionViewContentSize.height;
        
        
        
        NSString *title = nil;
        NSString *msg = nil;
        CMPopTipView *popView;
        switch (sender.tag) {
            case 1000:
                self.collectionView.frame = CGRectMake(0, 0, 300, height);
                self.collectionView.alwaysBounceVertical = YES;
                // 加载自定义View
                popView = [[CMPopTipView alloc] initWithCustomView:self.collectionView];
                break;
            case 1001:
                msg = @"这是一个简单的Demo,希望大家看明白,能用在自己的项目中";
                title = @"博主是逗逼";
                // 加载title和Msg的混合
                popView = [[CMPopTipView alloc] initWithTitle:title message:msg];
                break;
            case 1002:
                self.imageView.frame = CGRectMake(0, 0, 350, 300);
                popView = [[CMPopTipView alloc] initWithCustomView:self.imageView];
                break;
            case 1003:
                self.collectionView.frame = CGRectMake(0, 0, 300, height>400?400:height);
                self.collectionView.alwaysBounceVertical = YES;
                popView = [[CMPopTipView alloc] initWithCustomView:self.collectionView];
                break;
            case 1004:
                msg = @"With groups, Xcode stores in the project a reference to each individual file.";
                title = @"博主我爱你";
                popView = [[CMPopTipView alloc] initWithTitle:title message:msg];
                break;
            case 1005:
                self.imageView1.frame = CGRectMake(0, 0, 350, 300);
                popView = [[CMPopTipView alloc] initWithCustomView:self.imageView1];
                break;
                
            default:
                break;
        }
        popView.delegate = self;
        popView.cornerRadius = 5;
        // 是否有阴影
        //popView.hasShadow = YES;
        // 是否有梯度
        //popView.hasGradientBackground = NO;
        popView.backgroundColor = [UIColor colorWithRed:arc4random() % 256 / 255.0 green:arc4random() % 256 / 255.0 blue:arc4random() % 256 / 255.0 alpha:1];
        popView.textColor = [UIColor colorWithRed:arc4random() % 256 / 255.0 green:arc4random() % 256 / 255.0 blue:arc4random() % 256 / 255.0 alpha:1];
        // 0是Slide  1是pop  2是Fade但是有问题,用前两个就好了
        popView.animation = arc4random() % 1;
        // 立体效果,默认是YES
        popView.has3DStyle = arc4random() % 1;
        // 是否点击任意位子就影藏
        //popView.dismissTapAnywhere = YES;
        // 是否自定影藏
        //[popView autoDismissAnimated:YES atTimeInterval:5.0];
        
        [popView presentPointingAtView:sender inView:self.view animated:YES];
        [self.visiblePopTipViews addObject:popView];
        self.currentPopTipViewTarget = sender;
    }
    
}


代理方法和销毁PopView的方法

// 点击的时候取消PopView
- (void)dismissAllPopTipViews
{
    while ([self.visiblePopTipViews count] > 0) {
        CMPopTipView *popTipView = [self.visiblePopTipViews objectAtIndex:0];
        [popTipView dismissAnimated:YES];
        [self.visiblePopTipViews removeObjectAtIndex:0];
    }
}
// PopView的代理,当Pop消失的时候调用
- (void)popTipViewWasDismissedByUser:(CMPopTipView *)popTipView
{
    [self dismissAllPopTipViews];
    self.currentPopTipViewTarget = nil;
    NSLog(@"消失了");
    self.roundRectButtonPopTipView = nil;
}

下面是CMPopTipView的初始化属性,大家可自行修改测试

例如圆角cornerRadius是默认10,如果不需要圆角就可以去掉

// 默认值
//- (id)initWithFrame:(CGRect)frame
//{
//    if ((self = [super initWithFrame:frame])) {
//        // Initialization code
//        self.opaque = NO;
//        
//        _topMargin = 2.0;
//        _pointerSize = 12.0;
//        _sidePadding = 2.0;
//        _borderWidth = 1.0;
//        
//        self.textFont = [UIFont boldSystemFontOfSize:14.0];
//        self.textColor = [UIColor whiteColor];
//        self.textAlignment = NSTextAlignmentCenter;
//        self.backgroundColor = [UIColor colorWithRed:62.0/255.0 green:60.0/255.0 blue:154.0/255.0 alpha:1.0];
//        self.has3DStyle = YES;
//        self.borderColor = [UIColor blackColor];
//        self.hasShadow = YES;
//        self.animation = CMPopTipAnimationSlide;
//        self.dismissTapAnywhere = NO;
//        self.preferredPointDirection = PointDirectionAny;
//        self.hasGradientBackground = YES;
//        self.cornerRadius = 10.0;
//    }
//    return self;
//}

然后,我们再看看给UINavigationBar上面的UIBarButtonItem的方法调用

其他逻辑方法都基本一致,只是调用的最终弹窗方法不同

popView presentPointingAtBarButtonItem: animated:

// 点击了NavigationController上的按钮
- (void)gotoCart:(UIButton *)sender
{
    [self dismissAllPopTipViews];
    if (sender == self.currentPopTipViewTarget) {
        self.currentPopTipViewTarget = nil;
    }
    else
    {
        CGFloat height;
        [self.tableView reloadData];
        height  = self.tableView.contentSize.height;
        self.tableView.frame = CGRectMake(0, 0, 100, height);
        self.tableView.backgroundColor = [UIColor blackColor];
        self.tableView.alwaysBounceVertical = YES;
        CMPopTipView *popView = [[CMPopTipView alloc] initWithCustomView:self.tableView];
        popView.delegate = self;
        popView.cornerRadius = 5;
        popView.backgroundColor = [UIColor blackColor];
        popView.textColor = [UIColor whiteColor];
        // 0是Slide  1是pop  2是Fade但是有问题,用前两个就好了
        popView.animation = arc4random() % 1;
        // 立体效果,默认是YES
        popView.has3DStyle = arc4random() % 1;
        //        popView.dismissTapAnywhere = YES;
        //        [popView autoDismissAnimated:YES atTimeInterval:5.0];
        
        [popView presentPointingAtView:sender inView:self.view animated:YES];
        
        // 如果是原生的UIBarButtonItem,那么就调用这个方法
//        popView presentPointingAtBarButtonItem:<#(UIBarButtonItem *)#> animated:<#(BOOL)#>
        [self.visiblePopTipViews addObject:popView];
        self.currentPopTipViewTarget = sender;
    }
}


以上的主要方法差不多介绍完了,出来看效果

他默认的尖尖Point三角形底边和高度是相等的,这样的Point看起来就会比较矮小,各位

如果有兴趣跑起来Demo看看就一定会想改一下iOS 微信右上角下拉菜单效果之CMPopTipView,各种角度各种位置

iOS 微信右上角下拉菜单效果之CMPopTipView,各种角度各种位置


来看看他的源码,这种View的显示肯定在drawRect:的方法里面完成的

只截图该方法里面的一部分代码,我们只要把他处理的X坐标修改就行了

CGRect bubbleRect = [self bubbleFrame];
	
	CGContextRef c = UIGraphicsGetCurrentContext(); 
    
    CGContextSetRGBStrokeColor(c, 0.0, 0.0, 0.0, 1.0);	// black
	CGContextSetLineWidth(c, self.borderWidth);
    
	CGMutablePathRef bubblePath = CGPathCreateMutable();
	
	if (_pointDirection == PointDirectionUp) {
        // 这里的原点是point的尖尖
		CGPathMoveToPoint(bubblePath, NULL, _targetPoint.x+_sidePadding, _targetPoint.y);
        // 注意这里的X轴是默认给的_pointer的宽度,这个pointer是个正三角形,但是我们要个等腰的,所有X轴加上_pointer/2,Y轴加上_pointer,OK
		CGPathAddLineToPoint(bubblePath, NULL, _targetPoint.x+_sidePadding+_pointerSize/2, _targetPoint.y+_pointerSize);
		
		CGPathAddArcToPoint(bubblePath, NULL,
							bubbleRect.origin.x+bubbleRect.size.width, bubbleRect.origin.y,
							bubbleRect.origin.x+bubbleRect.size.width, bubbleRect.origin.y+_cornerRadius,
							_cornerRadius);
		CGPathAddArcToPoint(bubblePath, NULL,
							bubbleRect.origin.x+bubbleRect.size.width, bubbleRect.origin.y+bubbleRect.size.height,
							bubbleRect.origin.x+bubbleRect.size.width-_cornerRadius, bubbleRect.origin.y+bubbleRect.size.height,
							_cornerRadius);
		CGPathAddArcToPoint(bubblePath, NULL,
							bubbleRect.origin.x, bubbleRect.origin.y+bubbleRect.size.height,
							bubbleRect.origin.x, bubbleRect.origin.y+bubbleRect.size.height-_cornerRadius,
							_cornerRadius);
		CGPathAddArcToPoint(bubblePath, NULL,
							bubbleRect.origin.x, bubbleRect.origin.y,
							bubbleRect.origin.x+_cornerRadius, bubbleRect.origin.y,
							_cornerRadius);
        // 这里也要改掉,不然自动关闭的时候就不是等腰三角形了
		CGPathAddLineToPoint(bubblePath, NULL, _targetPoint.x+_sidePadding-_pointerSize/2, _targetPoint.y+_pointerSize);
	}
	else {
        // 上面改了那么下面也要改掉
		CGPathMoveToPoint(bubblePath, NULL, _targetPoint.x+_sidePadding, _targetPoint.y);
		CGPathAddLineToPoint(bubblePath, NULL, _targetPoint.x+_sidePadding-_pointerSize/2, _targetPoint.y-_pointerSize);
		
		CGPathAddArcToPoint(bubblePath, NULL,
							bubbleRect.origin.x, bubbleRect.origin.y+bubbleRect.size.height,
							bubbleRect.origin.x, bubbleRect.origin.y+bubbleRect.size.height-_cornerRadius,
							_cornerRadius);
		CGPathAddArcToPoint(bubblePath, NULL,
							bubbleRect.origin.x, bubbleRect.origin.y,
							bubbleRect.origin.x+_cornerRadius, bubbleRect.origin.y,
							_cornerRadius);
		CGPathAddArcToPoint(bubblePath, NULL,
							bubbleRect.origin.x+bubbleRect.size.width, bubbleRect.origin.y,
							bubbleRect.origin.x+bubbleRect.size.width, bubbleRect.origin.y+_cornerRadius,
							_cornerRadius);
		CGPathAddArcToPoint(bubblePath, NULL,
							bubbleRect.origin.x+bubbleRect.size.width, bubbleRect.origin.y+bubbleRect.size.height,
							bubbleRect.origin.x+bubbleRect.size.width-_cornerRadius, bubbleRect.origin.y+bubbleRect.size.height,
							_cornerRadius);
		CGPathAddLineToPoint(bubblePath, NULL, _targetPoint.x+_sidePadding+_pointerSize/2, _targetPoint.y-_pointerSize);
	}
    
	CGPathCloseSubpath(bubblePath);
    
    CGContextSaveGState(c);
	CGContextAddPath(c, bubblePath);
	CGContextClip(c);
