简单介绍思路


KJCallNotifyInfo数据模型


声明一个接受外界的数据模型,暂时我只需要图片地址,名字,唯一id(需要再添加就完事)

@interface KJCallNotifyInfo : NSObject
@property(nonatomic,strong)NSString *imageUrl;
@property(nonatomic,strong)NSString *name;
@property(nonatomic,strong)NSString *userid;
@end


单例模式


由于这玩意需要一直存在并且放在最顶层,所以我采用单例来设计

static KJCallNotifyView *_instance = nil;
+ (instancetype)kj_shareInstance{
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        if (_instance == nil) {
            _instance = [[KJCallNotifyView alloc] initWithFrame:CGRectMake(0, 0, kScreenW, kScreenH)];
            [kKeyWindow addSubview:_instance];
        }
    });
    return _instance;
}

当然你也可以不使用该单例,则按下面方式

__block KJCallNotifyView *view = [[KJCallNotifyView alloc]initWithFrame:CGRectMake(0, 64, kScreenW, kScreenH-64)];
[self.view addSubview:view];
view.maxCount = 5;
view.vanishTime = 5;
[view kj_tapBlock:^(KJCallNotifyInfo * _Nonnull info) {
}];
__block NSInteger index = 1000;
NSArray *names = @[@"Sone",@"痛苦的信仰",@"X"];
[button kj_addAction:^(UIButton * _Nonnull kButton) {
    [view kj_addCallNotify:^(KJCallNotifyInfo * _Nonnull info) {
        info.imageUrl = @"xxsf";
        info.userid = [NSString stringWithFormat:@"%ld",index];
        info.name = names[1];
    } RepetitionCondition:nil];
}];


手势穿透处理


不影响后面的交互效果

- (UIView*)hitTest:(CGPoint)point withEvent:(UIEvent*)event{
    NSInteger count = self.subviews.count;
    for (int i = 0; i < count; i++){
        UIView *childView = self.subviews[count - 1 - I];
        CGPoint childPoint = [self convertPoint:point toView:childView];
        UIView *view = [childView hitTest:childPoint withEvent:event];
        if (view) return view;
    }
    return nil;
}


KJCallView


来电样式UI处理

@implementation KJCallView
- (instancetype)kj_initWithFrame:(CGRect)frame Name:(NSString*)name{
    if (self==[super initWithFrame:frame]) {
        self.centerX = kScreenW/2;
        self.backgroundColor = UIColor.whiteColor;
        self.cornerRadius = kAutoH(48)/2;
        self.shadowColor = [UIColor colorWithRed:0/255.0 green:0/255.0 blue:0/255.0 alpha:0.16];
        self.shadowOffset = CGSizeMake(0,3);
        self.shadowRadius = 6;
        self.shadowOpacity = 1;
        CGFloat height = self.height;
        self.imageView = [[UIImageView alloc]initWithFrame:CGRectMake(5, 5, height-10, height-10)];
        self.imageView.cornerRadius = (height-10)/2;
        [self addSubview:self.imageView];
        self.button = [UIButton kj_createButtonWithImageName:@"button_like_norm"];
        self.button.frame = CGRectMake(self.width-18-8, 0, 18, 18);
        self.button.centerY = self.height/2;
        [self addSubview:self.button];
        self.label = [UILabel kj_createLabelWithText:name];
        [self addSubview:self.label];
        self.label.textColor = [UIColor colorWithRed:51/255.0 green:51/255.0 blue:51/255.0 alpha:1.0];
        self.label.font = [UIFont fontWithName:@"PingFang SC" size:14];
        CGFloat width = [self.label kj_calculateWidth];
        CGFloat maxw = self.button.x - self.imageView.maxX - 10 - 23 - 10;
        if (width>=maxw) width = maxw;
        self.label.frame = CGRectMake(self.imageView.maxX+10, 0, width, self.height);
        self.tvImageView = [[UIImageView alloc]initWithFrame:CGRectMake(self.label.maxX+2.5, 0, 23, 22)];
        self.tvImageView.image = kGetImage(@"wode_nor");
        self.tvImageView.centerY = self.height/2;
        [self addSubview:self.tvImageView];
    }
    return self;
}
- (void)kj_invalidateTimer{
    [_timer invalidate];
    _timer = nil;
}
@end


点击事件


- (void)kj_tapBlock:(void(^)(KJCallNotifyInfo *info))block{
    self.tapblock = block;
}

点击回调,传递出来处理点击的相关逻辑


添加来电消息


介绍主要方法和核心点,

displayCount:当前显示的UI个数属性

temps:存储模型数据

viewTemps:存储来电显示UI数据

kj_addCallNotify:RepetitionCondition::添加来电消息

@synchronized (@(self.displayCount)):互斥锁,保证正常运行

kj_viewIndex:Info::创建来电UI

kj_displayEnd::显示结束

kj_autoVanish::自动消失动画

kj_vanish::点叉消失动画

kj_changeIndex:Y::递归修改来电坐标


一、kj_addCallNotify:RepetitionCondition:


添加来电消息,self.repetition 控制是否重复显示,内部条件根据userid来判断是否重复

- (void)kj_addCallNotify:(void(^)(KJCallNotifyInfo *))block RepetitionCondition:(bool(^_Nullable)(KJCallNotifyInfo *))condition{
    KJCallNotifyInfo *info = [KJCallNotifyInfo new];
    if (block) block(info);
    if (self.repetition == NO) {
        __block bool skip = false;
        if (condition) {
            for (KJCallNotifyInfo *_info in self.temps) {
                skip = condition(_info);
                if (skip) break;
            }
        }else{
            [self.temps enumerateObjectsUsingBlock:^(KJCallNotifyInfo * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
                if ([info.userid isEqualToString:obj.userid]) {
                    skip = true;*stop = YES;
                }
            }];
        }
        if (skip) return;
        [self.temps addObject:info];
    }
    @synchronized (@(self.displayCount)) {
        self.displayCount++;
        KJCallView *view = [self kj_viewIndex:self.displayCount Info:info];
        [self.viewTemps addObject:view];
        [self addSubview:view];
        if (self.displayCount > self.maxCount) {
            KJCallView *fristView = self.viewTemps.firstObject;
            [self kj_autoVanish:fristView];
            [self kj_displayEnd:fristView];
        }
    }
}


二、kj_viewIndex:Info:


创建UI控件,添加计时器view.timer来管理自动消失

- (KJCallView*)kj_viewIndex:(NSInteger)index Info:(KJCallNotifyInfo*)info{
    CGFloat y = kAutoH(17) + (index-1) * kAutoH(58) + kSTATUSBAR_HEIGHT - 20;
    __block KJCallView *view = [[KJCallView alloc]kj_initWithFrame:CGRectMake(0, y, kAutoW(170), kAutoH(48)) Name:info.name];
    view.tag = 520 + index - 1;
    view.info = info;
    view.imageView.image = [UIImage imageNamed:info.imageUrl];
    _weakself;
    void (^kRemove)(bool tapX) = ^(bool tapX){
        if (tapX) {
            [weakself kj_vanish:view];
        }else{
            [weakself kj_autoVanish:view];
        }
        [weakself kj_displayEnd:view];
    };
    [view kj_AddTapGestureRecognizerBlock:^(UIView * _Nonnull __view, UIGestureRecognizer * _Nonnull gesture) {
        if (weakself.tapblock) {
            weakself.tapblock(view.info);
            if (weakself.tapVanish) {
                [weakself kj_vanish:view];
                [weakself kj_displayEnd:view];
            }
        }
    }];
    [view.button kj_addAction:^(UIButton * _Nonnull kButton) {
        kRemove(true);
    }];
    view.timer = [NSTimer kj_scheduledNoImmediateTimerWithTimeInterval:self.vanishTime Block:^(NSTimer * _Nonnull timer) {
        kRemove(false);
    }];
    [[NSRunLoop mainRunLoop] addTimer:view.timer forMode:NSRunLoopCommonModes];
    [view.timer fire];
    return view;
}


三、kj_displayEnd:


显示结束,清理数据,关闭计时器,显示个数处理

- (void)kj_displayEnd:(KJCallView*)view{
    [view kj_invalidateTimer];
    [self.viewTemps removeObject:view];
    if (self.repetition == NO) {
        [self.temps removeObject:view.info];
    }
    @synchronized (@(self.displayCount)) {
        self.displayCount--;
    }
}


四、kj_autoVanish:


自动消失处理

- (void)kj_autoVanish:(KJCallView*)view{
    [UIView animateWithDuration:.5 animations:^{
        [self kj_changeIndex:0 Y:-kAutoH(48)];
    } completion:^(BOOL finished) {
        [view removeFromSuperview];
    }];
}


五、kj_vanish:


点叉消失处理,当前点击控件消失,其余依次补位

- (void)kj_vanish:(KJCallView*)view{
    [UIView animateWithDuration:.5 animations:^{
        view.hidden = 0;
        if (view.tag == 520) {
            [self kj_changeIndex:0 Y:-kAutoH(48)];
        }else{
            [self kj_changeIndex:view.tag-520 Y:view.y];
        }
    } completion:^(BOOL finished) {
        [view removeFromSuperview];
    }];
}


六、kj_changeIndex:Y:


递归来处理补位

- (void)kj_changeIndex:(NSInteger)index Y:(CGFloat)y{
    KJCallView *view = self.viewTemps[index];
    view.tag = 520 + index - 1;
    CGFloat xy = view.y;view.y = y;
    if (index+1<self.viewTemps.count) [self kj_changeIndex:index+1 Y:xy];
}


使用示例


- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    UIButton *button = [UIButton kj_createButtonWithFontSize:15 Title:@"测试来电" TextColor:UIColor.orangeColor];
    button.frame = CGRectMake(0, 0, 100, 50);
    button.centerX = kScreenW/2;
    button.centerY = kScreenH - 100;
    button.borderWidth = 1;
    button.borderColor = UIColor.orangeColor;
    [self.view addSubview:button];
    __block NSInteger index = 520;
    NSArray *names = @[@"Sone",@"痛苦的信仰",@"X",@"yang"];
    [button kj_addAction:^(UIButton * _Nonnull kButton) {
        [[KJCallNotifyView kj_shareInstance] kj_addCallNotify:^(KJCallNotifyInfo * _Nonnull info) {
            info.imageUrl = @"xxsf";
            info.userid = [NSString stringWithFormat:@"%ld",index++];
            info.name = names[index%4];
        } RepetitionCondition:^bool(KJCallNotifyInfo * _Nonnull info) {
            if ([info.name isEqualToString:names[index%4]]) {
                return true;
            }
            return false;
        }];
    }];
    [KJCallNotifyView kj_shareInstance].maxCount = 5;
    [KJCallNotifyView kj_shareInstance].vanishTime = 7;
    [KJCallNotifyView kj_shareInstance].repetition = YES;
    [[KJCallNotifyView kj_shareInstance] kj_tapBlock:^(KJCallNotifyInfo * _Nonnull info) {
        NSLog(@"-----%@",info);
        [self.navigationController popViewControllerAnimated:YES];
    }];
}

iOS开发之指定UIView的某几个角(小于4)为圆角
在iOS开发中,我们经常会遇到View设置圆角的问题,如果需要将UIView的4个角全部都为圆角,做法相当简单,只需设置其Layer的cornerRadius属性即可(项目需要使用QuartzCore框架)。而若要指定某几个角(小于4)为圆角而别的不变时,这种方法就不好用了。
