概述
自定義蒙層彈起View,點擊一下遮罩或界面上關閉按鈕,頁面會自動下去(從上向下)
詳細
在一些少數據沒必要跳轉下個界面,我們的產品大大就設計了在當前界面的底部彈上來一個View!
看下項目里截圖:

一、主要思路
1、首先封裝這個自定義蒙層彈起View: ZLBounceView
2、在ZLTuanNumView里添加你需要的視圖 View
3、使用代理和模型傳值
二、程序實現
Step1. 首先封裝這個自定義蒙層彈起View: ZLBounceView
設置界面相關:
- (void)setupContent {
self.frame = CGRectMake(0, 0, UI_View_Width, ZLBounceViewHight);
//alpha 0.0 白色 alpha 1 :黑色 alpha 0~1 :遮罩顏色,逐漸
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];
// 右上角關閉按鈕
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];
}
}
展示從底部向上彈出的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];
}
移除從上向底部彈下去的UIView(包含遮罩):
- (void)disMissView {
[_contentView setFrame:CGRectMake(0, UI_View_Height - ZLBounceViewHight, UI_View_Width, ZLBounceViewHight)];
[UIView animateWithDuration:0.3f
animations:^{
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:
//展示從底部向上彈出的UIView(包含遮罩) - (void)showInView:(UIView *)view;
現在的效果圖:

Step2. 在ZLBounceView里添加你需要的視圖 View, 這里以我的 tableView 為例
<UITableViewDelegate, UITableViewDataSource>
自定義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: 這里用假數據測試
- (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;
// 假數據
cell.textLabel.text = [NSString stringWithFormat:@"%ld", (long)indexPath.row];
cell.detailTextLabel.text = @"已購";
self.total.text = [NSString stringWithFormat:@"總計:%@噸", @"100"];
return cell;
}
Step3. 使用代理和模型傳值
3.1 在當前ViewController中的所需按鈕,添加點擊事件
[testBtn addTarget:self action:@selector(testBtnClicked) forControlEvents:UIControlEventTouchUpInside];
3.2 添加點擊事件則為創建當前彈起View
// 詳情展開view @property (nonatomic, strong) ZLBounceView *tuanNumView;
- (void)testBtnClicked {
_tuanNumView = [[ZLBounceView alloc]init];
[_tuanNumView showInView:self.view];
}
3.3 我這里使用假數據,正常情況則是請求數據或者上個界面的數據用 Model 傳過來
_tuanNumView.tuanModel = self.orderModel;
Step4. 加載從底部向上彈起的UIView; 點擊一下遮罩或界面上關閉按鈕,頁面會自動下去(從上向下)
運行效果圖如下:

三、其他補充

目前是項目中直接操作, 界面性問題可以根據自己項目需求調整即可, 具體可參考代碼, 項目能夠直接運行!
