iOS自定義從底部彈上來的View

在一些少資料沒必要跳轉下個介面,我們的產品大大就設計了在當前介面的底部彈上來一個View!

看下專案裡截圖:

一、主要思路

1、首先封裝這個自定義蒙層彈起View: ZLBounceView

2、在ZLTuanNumView裡新增你需要的檢視 View

3、使用代理和模型傳值

二、程式實現

Step1. 首先封裝這個自定義蒙層彈起View: ZLBounceView

設定介面相關:

- (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 檔案裡露出方法:

//展示從底部向上彈出的UIView(包含遮罩)
- (void)showInView:(UIView *)view;

Step2. 在ZLBounceView裡新增你需要的檢視 View, 這裡以我的 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: 這裡用假資料測試

- (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;
    
    // 假資料
    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,新增點選事件

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

3.2 新增點選事件則為建立當前彈起View

// 詳情展開view
@property (nonatomic, strong) ZLBounceView *tuanNumView;
- (void)testBtnClicked {
    
    _tuanNumView = [[ZLBounceView alloc]init];
    [_tuanNumView showInView:self.view];
}

3.3 我這裡使用假資料,正常情況則是請求資料或者上個介面的資料用 Model 傳過來

_tuanNumView.tuanModel = self.orderModel;

Step4. 載入從底部向上彈起的UIView; 點選一下遮罩或介面上關閉按鈕,頁面會自動下去(從上向下)

執行效果圖如下:

目前是專案中直接操作, 介面性問題可以根據自己專案需求調整即可, 具體可參考程式碼, 專案能夠直接執行!
