iOS开发--ChildViewController实现订单页的切换

　　先不说废话, 上效果图, 代码量也不大, 也不上传github骗星星了, 你们复制粘贴下代码, 就可以轻而易举的弄出一个小demo.

　　

　　这个代码的实现并不复杂, 甚至于说非常简单, 就是逻辑有点小绕, 下面将用代码详细讲解下.

　　childViewController方便在一个vc上面呈现出这种多种vc的效果, 相信好处百度上面说的多了去了, 这里只说实现.

　　首先, 需要新建一个父vc和五个子vc, 这里就不多说了, 先给大家看看进入父vc后的上面的btn控件封装, 以及方法回调.

　　IndentButtonView.h中代码

1 #import "RootClassView.h"
2 
3 typedef void(^buttonBlock)(NSInteger);
4 
5 @interface IndentButtonView : RootClassView
6 
7 @property(nonatomic, copy)buttonBlock block;
8 
9 @end

　　这里声明了一个具有整形参数的block闭包属性, 用于捕获button的tag值来作为参数回调.

　　IndentButtonView.m中代码, 有我自己定义的宏和基类, 你们按照你们自己的习惯来写就好.

 1 #import "IndentButtonView.h"
 2 #import "ALLHeaderFile.pch"
 3 @implementation IndentButtonView
 4 
 5 - (instancetype)initWithFrame:(CGRect)frame{
 6     self = [super initWithFrame:frame];
 7     if (self) {
 8         [self createButton];
 9     }
10     return self;
11 }
12 
13 - (void)createButton{
14     NSArray *nameArray = @[@"全部", @"待付款", @"待收货", @"待评价", @"退换货"];
15     for (NSInteger i = 0; i < 5; i++) {
16         UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
17         button.frame = CGRectMake(150 / 2 * i, 0, 150 / 2, self.H);
18         [button setTitle:nameArray[i] forState:UIControlStateNormal];
19         button.tag = 2006 + i;
20         [button addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
21         button.backgroundColor = [UIColor grayColor];
22         button.titleLabel.textColor = [UIColor redColor];
23         button.titleLabel.font = [UIFont systemFontOfSize:15];
24         [self addSubview:button];
25     }
26 }
27 
28 - (void)buttonAction:(UIButton *)button{
29     NSLog(@"第%ld个按钮被点击了", button.tag -2006);
30     _block(button.tag - 2006);
31 }
32 @end

　　当点击button的时候, 触发闭包传值回调. 通过button的tag值判断, 在闭包实现的地方也会有不同的结果. 这样一个button按钮条的封装就完成了.

　　然后是外部的一个自定义cell, 我选择了用四个imageView作为订单四个状态的按钮. 这个自定义cell同样声明了一个闭包属性, 作为以后的回调, 传递的也是imageView的tag值作为参数.

　　.h

#import "RootClassTableViewCell.h"
#import "RootClassImageView.h"
typedef void(^indentBlock)(NSInteger);
@interface IndentTableViewCell : RootClassTableViewCell
@property(nonatomic, copy)indentBlock block;
@end

　　.m中代码

　　

 1 #import "IndentTableViewCell.h"
 2 #import "XCLHeader.h"
 3 #import "RootClassLabel.h"
 4 @implementation IndentTableViewCell
 5 
 6 - (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
 7 {
 8     self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
 9     if (self) {
10         [self createCell];
11     }
12     return self;
13 }
14 
15 - (void)createCell
16 {
17     //订单Label
18     RootClassLabel *indentLabel = [[RootClassLabel alloc]initWithFrame:CGRectMake(48, 18, 30, 15)];
19     indentLabel.text = @"订单";
20     indentLabel.font = [UIFont systemFontOfSize:15];
21     [self.contentView addSubview:indentLabel];
22     
23     //查看全部订单
24     RootClassLabel *checkIndentLabel = [[RootClassLabel alloc]initWithFrame:CGRectMake(SCREEN_WIDTH - (168 + 10 + 14 + 40) / 2, 38 / 2, 168 / 2, 28 / 2)];
25     checkIndentLabel.text = @"查看全部订单";
26     checkIndentLabel.font = [UIFont systemFontOfSize:14];
27     [self.contentView addSubview:checkIndentLabel];
28     
29     RootClassImageView *imageView = [[RootClassImageView alloc]initWithFrame:CGRectMake(checkIndentLabel.X + checkIndentLabel.W + 5, checkIndentLabel.Y, 7, 14)];
30     [self.contentView addSubview:imageView];
31     
32     /**循环实例化imageView对象
33      *
34      *待付款
35      *
36      *待收货
37      *
38      *待评价
39      *
40      *退换货
41      *
42      */
43     
44     for (NSInteger i = 0; i < 4; i++) {
45         RootClassImageView *imageView = [[RootClassImageView alloc]initWithFrame:CGRectMake(41 + 167 / 2 * i, 117 / 2, 85 / 2, 85 / 2)];
46         //imageView增加tag值
47         imageView.tag = 2002 + i;
48         
49         //打开imageView交互
50         imageView.userInteractionEnabled = YES;
51         
52         //为imageView添加轻拍手势
53         UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapAction:)];
54         [imageView addGestureRecognizer:tap];
55         imageView.t;
56         [self.contentView addSubview:imageView];
57     }
58 }
59 
60 
61 - (void)tapAction:(UITapGestureRecognizer *)tap
62 {
63     _block(tap.view.tag - 2002);
64 }
65 
66 - (void)layoutSubviews
67 {
68     [super layoutSubviews];
69 }

　　自定义cell在重用池协议中代码, 对闭包进行了实现, 同时传递值给要跳转的vc.

 1         //订单
 2         static NSString *indentifier = @"indent";
 3         IndentTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:indentifier];
 4         if (!cell) {
 5             cell = [[IndentTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:indentifier];
 6             cell.selectionStyle = 0;
 7         }
 8         cell.block = ^(NSInteger index){
 9             //index就是通过block传递过来imageView的tag值.
10             MyIndentViewController *myIndentViewController = [MyIndentViewController new];
11             //当点击imageView后, 将图片的tag值传递给vc, vc通过这个值来布局, 以实现点击不同的imageView, 使页面中呈现不同的子视图.
12             myIndentViewController.index = index + 1;
13             [self.navigationController pushViewController: myIndentViewController animated:1];
14         };
15         return cell;

　　可能上面传tag值让大家很迷茫, 现在把最重要的实现部分的VC代码拿出来, 大家就好懂了.

　　通过这么简单的几步, 就实现了如上界面.
