1。首先cell里面

@protocol personal_Center_CellDelegate <NSObject>

- (void)cellDontLikeClick:(UITableViewCell *)cell rectofBtn:(CGRect)rect;
@optional
@end

@property (nonatomic, weak) id<personal_Center_CellDelegate> delegate;

 [_toprightClickButton addTarget:self action:@selector(toprightClickButtonClick:) forControlEvents:UIControlEventTouchUpInside];

//把自己 和按钮的 frame 传出 
- (void)toprightClickButtonClick:(UIButton *)btn
{
    if (_delegate && [_delegate respondsToSelector:@selector(cellDontLikeClick:rectofBtn:)]) {
        [_delegate cellDontLikeClick:self rectofBtn:btn.frame];
    }
}

2 VC 里面

- (void)cellDontLikeClick:(UITableViewCell *)cell rectofBtn:(CGRect)rect
{
    NSIndexPath *indexpatch = [_tableView indexPathForCell:cell];
    CGRect rectInTableView = [_tableView rectForRowAtIndexPath:indexpatch];
    CGRect rectInSuperview = [_tableView convertRect:rectInTableView toView:self.view];

    //这里是cell 的位置
    NSLog(@"%f,%f", rectInSuperview.origin.x, rectInSuperview.origin.y);

    CGRect realrect = CGRectMake(rectInSuperview.origin.x + rect.origin.x, rectInSuperview.origin.y + rect.origin.y, rect.size.width, rect.size.height);
    //这里是btn 的位置
    NSLog(@"%f,%f", rect.origin.x, rect.origin.y);
    NSLog(@"%f,%f", realrect.origin.x, realrect.origin.y);
    [self alertviewMake:realrect cell:cell];
}

- (void)alertviewMake:(CGRect)realrect cell:(UITableViewCell *)realcell
{
    NSIndexPath *indexpatch = [_tableView indexPathForCell:realcell];

    NSLog(@"indexpatch.row == %ld", indexpatch.row);

    DD_Media_AlertView *view = [[DD_Media_AlertView alloc] init];
    view.frame = CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT);
    UIWindow *window = [UIApplication sharedApplication].keyWindow;
    [window addSubview:view];
}

3.封装的 DD_Media_AlertView

#import <UIKit/UIKit.h>

NS_ASSUME_NONNULL_BEGIN
typedef void (^topClickButtonBlock)(NSString *buttontitle);
typedef void (^bottomClickButtonBlock)(NSString *buttontitle);


@interface DD_Media_AlertView : UIView
@property (nonatomic, strong) UIButton *bgView; //灰色背景

@property (nonatomic, strong) UIView *contentView;         //按钮bg
@property (nonatomic, strong) UIButton *topClickButton;    //上边按钮
@property (nonatomic, strong) UIButton *bottomClickButton; //下边按钮
@property (nonatomic, strong) UIImageView *tipimageView;   //小尖

@property (nonatomic, copy) topClickButtonBlock topblock;
@property (nonatomic, copy) bottomClickButtonBlock bottomblock;

- (void)setToptitle:(NSString *)toptitle BottomTitle:(NSString *)bottomtitle;
