iOS封装弹框试图

在项目中经常会用到这样的需求，我们一般都是自己去定制（如下图）

下面讲讲具体的封装，有需要的朋友可以直接拿走。

首先我们需要创建一个类 继承自UIView

在GiveUpPayView.h中：

#import <UIKit/UIKit.h>

@interface GiveUpPayView : UIView

//这个block是用来执行确定按钮点击以后 传执行的内容
@property (nonatomic, copy)void(^block)();

@end

在GiveUpPayView.m中：

#import "GiveUpPayView.h"

@interface GiveUpPayView ()
@property (weak, nonatomic) IBOutlet UIView *backGroundView;

@end

@implementation GiveUpPayView

- (instancetype)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        self = [[[NSBundle mainBundle] loadNibNamed:@"GiveUpPayView" owner:self options:nil] firstObject];
        self.frame = CGRectMake(0, 0, frame.size.width, frame.size.height);
        [self setView];
    }
    return self;
}

#pragma mark - 给view添加点击手势
- (void)setView{
    
    
    UITapGestureRecognizer *backGroundViewClicked = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(backGroundViewClicked)];
    backGroundViewClicked.numberOfTapsRequired = 1;
    [self.backGroundView addGestureRecognizer:backGroundViewClicked];
    
}

- (void)backGroundViewClicked{
    [self removeFromSuperview];
}

- (IBAction)yesButtonClicked:(id)sender {
    
    self.block();
}

- (IBAction)cancalButtonClicked:(id)sender {
   
    [self removeFromSuperview];
    
}

@end

新建一个XIB ：

其中的灰色背景就是backView 将整个xib的class设置成刚才建立的GiveUpPayView 这样就完成了关联。

封装视图的使用：

GiveUpPayView *view = [[GiveUpPayView alloc] initWithFrame:CGRectMake(0, 0, WIDTH, HEIGHT)];
    
    view.block = ^(){
        
        [self giveUpPay];

    };
    
    [self.view addSubview:view];
