概述

详细

在一些少数据没必要跳转下个界面,我们的产品大大就设计了在当前界面的底部弹上来一个View!

看下项目里截图:

一、主要思路

1、首先封装这个自定义蒙层弹起View: ZLBounceView

2、在ZLTuanNumView里添加你需要的视图 View

3、使用代理和模型传值

二、程序实现

Step1. 首先封装这个自定义蒙层弹起View: ZLBounceView

设置界面相关:

- (void)setupContent {self.frame = CGRectMake(0, 0, UI_View_Width, ZLBounceViewHight);//alpha 0.0  白色   alpha 1 ：黑色   alpha 0～1 ：遮罩颜色，逐渐self.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.4];self.userInteractionEnabled = YES;[self addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(disMissView)]];if (_contentView == nil) {_contentView = [[UIView alloc]initWithFrame:CGRectMake(0, UI_View_Height - ZLTuanNumViewHight, UI_View_Width, ZLBounceViewHight)];_contentView.backgroundColor = [UIColor whiteColor];[self addSubview:_contentView];// 右上角关闭按钮UIButton *closeBtn = [UIButton buttonWithType:UIButtonTypeCustom];closeBtn.frame = CGRectMake(_contentView.width - 20 - 15, 15, 20, 20);[closeBtn setImage:[UIImage imageNamed:@"guanbi"] forState:UIControlStateNormal];[closeBtn addTarget:self action:@selector(disMissView) forControlEvents:UIControlEventTouchUpInside];[_contentView addSubview:closeBtn];}
}

展示从底部向上弹出的UIView（包含遮罩）:

- (void)showInView:(UIView *)view {if (!view) {return;}[view addSubview:self];[view addSubview:_contentView];[_contentView setFrame:CGRectMake(0, UI_View_Height, UI_View_Width, ZLBounceViewHight)];[UIView animateWithDuration:0.3 animations:^{self.alpha = 1.0;[_contentView setFrame:CGRectMake(0, UI_View_Height - ZLBounceViewHight, UI_View_Width, ZLBounceViewHight)];} completion:nil];
}

移除从上向底部弹下去的UIView（包含遮罩）:

- (void)disMissView {[_contentView setFrame:CGRectMake(0, UI_View_Height - ZLBounceViewHight, UI_View_Width, ZLBounceViewHight)];[UIView animateWithDuration:0.3fanimations:^{self.alpha = 0.0;[_contentView setFrame:CGRectMake(0, UI_View_Height, UI_View_Width, ZLBounceViewHight)];}completion:^(BOOL finished){[self removeFromSuperview];[_contentView removeFromSuperview];}];}

.h 文件里露出方法:

//展示从底部向上弹出的UIView（包含遮罩）
- (void)showInView:(UIView *)view;

现在的效果图:

Step2. 在ZLBounceView里添加你需要的视图 View, 这里以我的 tableView 为例

<UITableViewDelegate, UITableViewDataSource>

自定义ZLBounceView:

        UITableView *detailTableView = [[UITableView alloc] init];detailTableView.backgroundColor = [UIColor clearColor];detailTableView.frame = CGRectMake(0, CGRectGetMaxY(partner.frame), UI_View_Width, ZLBounceViewHight - tuan.frame.size.height - partner.frame.size.height - 50 - 20);[_contentView addSubview:detailTableView];detailTableView.delegate = self;detailTableView.dataSource = self;self.detailTableView = detailTableView;self.detailTableView.separatorStyle = UITableViewCellSeparatorStyleNone;

UITableViewDelegate: 这里用假数据测试

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {static NSString *ID = @"cell";UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:ID];if (cell == nil) {cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:ID];cell.backgroundColor = [UIColor clearColor];cell.textLabel.font = [UIFont systemFontOfSize:13];cell.textLabel.textColor = ZLColor(102, 102, 102);cell.detailTextLabel.font = [UIFont systemFontOfSize:13];cell.detailTextLabel.textColor = ZLColor(102, 102, 102);}cell.selectionStyle = UITableViewCellSelectionStyleNone;// 假数据cell.textLabel.text = [NSString stringWithFormat:@"%ld", (long)indexPath.row];cell.detailTextLabel.text = @"已购";self.total.text = [NSString stringWithFormat:@"总计:%@吨", @"100"];return cell;
}

Step3. 使用代理和模型传值

3.1 在当前ViewController中的所需按钮，添加点击事件

[testBtn addTarget:self action:@selector(testBtnClicked) forControlEvents:UIControlEventTouchUpInside];

3.2 添加点击事件则为创建当前弹起View

// 详情展开view
@property (nonatomic, strong) ZLBounceView *tuanNumView;

- (void)testBtnClicked {_tuanNumView = [[ZLBounceView alloc]init];[_tuanNumView showInView:self.view];
}

3.3 我这里使用假数据,正常情况则是请求数据或者上个界面的数据用 Model 传过来

_tuanNumView.tuanModel = self.orderModel;

Step4. 加载从底部向上弹起的UIView; 点击一下遮罩或界面上关闭按钮，页面会自动下去（从上向下）

运行效果图如下:

三、其他补充

目前是项目中直接操作, 界面性问题可以根据自己项目需求调整即可, 具体可参考代码, 项目能够直接运行!
