6、悬浮窗的封装

因为之前做游戏SDK的开发，主要是集成登录、注册、充值以及最重要的悬浮窗的制作；封装成一个类，方便自己以后使用😄；
我的Demo地址：https://github.com/hongbaoshi/LZWFloatWindow
参考地址：https://github.com/search?utf8=%E2%9C%93&q=DYYFloatWindow

创建引入：

- (void)viewDidLoad {
    [super viewDidLoad];
    
    //防止与主window冲突，延迟执行；
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.5 * NSEC_PER_SEC)), dispatch_get_main_queue(),^{
        [self creatFloatWindow];
    });
    
}



-(void)creatFloatWindow
{
    _change_floatWindow = [[LZWFloatWindow alloc] initWithFrame:CGRectMake(100, 100, 50,50) andWithMainImageName:@"z" andWithTitleDic:@{@"ddd":@"用户中心",@"eee":@"退出登录",@"fff":@"客服中心"} andWithStartBtnTag:100 andWithAnimationColor:[UIColor purpleColor]];
    
    _change_floatWindow.backBlock = ^(NSInteger tag){
        NSLog(@"点击第%ld个按钮",tag);
    };
}

具体实现：

#import <UIKit/UIKit.h>

typedef void(^MyBlock)(NSInteger tag);

@interface LZWFloatWindow : UIWindow

@property(nonatomic,strong)MyBlock backBlock;

-(id)initWithFrame:(CGRect)frame andWithMainImageName:(NSString *)bgName andWithTitleDic:(NSDictionary *)titleDic andWithStartBtnTag:(int)startTag andWithAnimationColor:(UIColor *)color;

@end

#import "LZWFloatWindow.h"
#import <CoreMotion/CoreMotion.h>

#define LZW_WIDTH [[UIApplication sharedApplication].windows firstObject].bounds.size.width
#define WZFlashInnerCircleInitialRaius  20

@interface LZWFloatWindow()

@property(nonatomic,strong)UIButton *mainBtn;
@property(nonatomic,assign)BOOL isShowDetail;//是否展开悬浮窗，默认不展开；
@property(nonatomic,assign)CGRect startFrame;//悬浮窗初始显示位置
@property(nonatomic,assign)NSInteger btnWidth;//各个按钮的宽；

@property(nonatomic,strong)UIView *contentView;//点击btn展示的详情界面；
@property(nonatomic,strong)NSDictionary *titleDic;//保存详情页面标题的字典；
@property(nonatomic,assign)int btnTag;//详情每个按钮的tag值；
@property(nonatomic,strong)UIPanGestureRecognizer *movePan;//悬浮窗移动手势

@property(assign, nonatomic) NSTimeInterval gyroUpdateInterval;

@property(nonatomic,assign)BOOL isHide;

@property(nonatomic,strong)CAAnimationGroup *animationGroup;
@property(nonatomic,strong)CAShapeLayer *circleShape;
@property(nonatomic,strong)UIColor *animationColor;
