系统弹层不好看？那就自己封装一个弹层小控件吧~

新建一个类，继承自UIView，（类名MessagePopView）

头文件中的代码：

#import <UIKit/UIKit.h>

@interface MessagePopView : UIView
-(void) hidePopView;
-(void) showPopView;

@end

.m文件实现：

#import "MessagePopView.h"
#define SCREEN_WIDTH   ([UIScreen mainScreen].bounds.size.width)
#define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)
@interface MessagePopView ()

@property (strong, nonatomic)UIImageView *imgView;
@property (strong, nonatomic)UIImageView *imgViewMessage;
@property (strong, nonatomic)UILabel *backgroundLabel;
@property (strong, nonatomic)UIView *contentView;
@property (nonatomic, strong)UIButton *clearMessageBtn;
@property (nonatomic, strong)UIButton *cancelBtn;

@end

@implementation MessagePopView

- (instancetype)initWithFrame:(CGRect)frame{
    if (self = [super initWithFrame:frame]) {
        [self drawView];
    }
    return self;
}

- (void)drawView{

    //半透明背景
    self.imgView = [[UIImageView alloc]initWithImage:[UIImage i
