//需要的效果

1.設置window的根視圖控制器為一個UITableViewController

#import "AppDelegate.h"
#import "YCTableViewController.h"
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.window.backgroundColor = [UIColor whiteColor];
self.window.rootViewController = [[UINavigationController alloc] initWithRootViewController:[[YCTableViewController alloc] init]];
[self.window makeKeyAndVisible];
return YES;
}

3.自定義tableview的header和cell

4.collectionView布局和自定義item

#import <UIKit/UIKit.h>
@interface SectionHeaderViewCollectionReusableView : UICollectionReusableView
@property(nonatomic, strong)UILabel *titleLabel;
@end
#import "SectionHeaderViewCollectionReusableView.h"
@implementation SectionHeaderViewCollectionReusableView
-(instancetype)initWithFrame:(CGRect)frame

{
_titleLabel = [[UILabel alloc]init];
[self addSubview:_titleLabel];
}
-(void)layoutSubviews
{
[super layoutSubviews];
_titleLabel.frame = CGRectMake(20, 30, 375, 50);
_titleLabel.font = [UIFont systemFontOfSize:20];
}
@end
collectionView的item
#import <UIKit/UIKit.h>
@interface MyCollectionViewCell : UICollectionViewCell
typedef enum : NSInteger
{
cellStyleDefault = 0,
cellStyleSelected = 1,
cellStyleAdd = 2,
}CollectionViewCellStyle;
@property(nonatomic, assign)CollectionViewCellStyle cellStyle;
@property(nonatomic, strong)UIImageView *photo;
@property(nonatomic, strong)UIImageView *imageView;
@property(nonatomic, strong)NSArray *array;
@property(nonatomic, strong)NSMutableArray *dataArray;
-(void)layoutSubviews;
@end
#import "MyCollectionViewCell.h"
@implementation MyCollectionViewCell
-(instancetype)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
_photo = [[UIImageView alloc]init];
_imageView = [[UIImageView alloc]init];
}
return self;
}
-(void)layoutSubviews
{
[super layoutSubviews];
[_photo setFrame:self.bounds];

self.layer.masksToBounds = YES;
self.layer.borderWidth = 1.8;
//self.layer.cornerRadius = 20;
self.backgroundColor = [UIColor whiteColor];
[self.contentView addSubview:_photo];
break;
case cellStyleSelected:

break;
default:

}
}
@end

5.model

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
@interface AppModel : NSObject
@property (nonatomic, assign) BOOL Is_Open;
@end
#import "AppModel.h"
@implementation AppModel
@end
//設置model是為了設置一個bool類型的變量,用來記錄tableview的cell是否展開,從而進行reloadSection操作,進行動畫展開或收縮.
