悬浮按钮，先上图

很长时间没写了，手法生疏，直接上代码吧
- SheetControlView.h
#import <UIKit/UIKit.h>
NS_ASSUME_NONNULL_BEGIN
@interface SheetControlView : UIWindow
/// 展示
+ (void)show;
/// 隐藏
+ (void)hidden;
@end

- SheetControlView.m
#import "SheetControlView.h"

static CGFloat widthWindow = 120.f;
static CGFloat bottomWindow = 160.f;
static CGFloat heightButton = 40.f;
static CGFloat durationTime = 0.35;
typedef NS_ENUM(NSUInteger, SheetButtonShowType) {
SheetButtonShowHalfType,// 展示一半
SheetButtonShowFullType,// 展示全部
};
@interface SheetControlView()
/// 展示类型

/// 悬浮按钮
@property (nonatomic, strong) UIButton *sheetButton;
@end
@implementation SheetControlView

[UIView animateWithDuration:durationTime animations:^{

#pragma mark - 按钮懒加载

用法
- 以一个ViewController的.m文件为例：
#import "ViewController.h"
#import "SheetControlView.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = UIColor.groupTableViewBackgroundColor;
UIButton *showButton = [[UIButton alloc] initWithFrame:CGRectMake(([UIScreen mainScreen].bounds.size.width - 160) / 2, 120, 160, 40)];
[showButton setTitle:@"展示" forState:0];
showButton.backgroundColor = UIColor.redColor;
showButton.tag = 0;
[showButton addTarget:self action:@selector(buttonSelect:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:showButton];
UIButton *hiddenButton = [[UIButton alloc] initWithFrame:CGRectMake(([UIScreen mainScreen].bounds.size.width - 160) / 2, 180, 160, 40)];
[hiddenButton setTitle:@"隐藏" forState:0];
hiddenButton.backgroundColor = UIColor.orangeColor;
hiddenButton.tag = 1;
[hiddenButton addTarget:self action:@selector(buttonSelect:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:hiddenButton];
}
- (void)buttonSelect:(UIButton *)sender {
if (sender.tag == 0) {
[SheetControlView show];
}else {
[SheetControlView hidden];
}
}
@end
