抽屉ViewDeck的简单使用

使用pod导入三方库ViewDeck

pod 'ViewDeck', '~> 3.1.0'

//  QYHViewDeck.h

#import <Foundation/Foundation.h>
#import <ViewDeck/ViewDeck.h>

@interface QYHViewDeck : NSObject <IIViewDeckControllerDelegate>

@property (nonatomic, strong) IIViewDeckController *viewDeckController;

+ (instancetype)sharedInstance;
- (IIViewDeckController *)wrappedViewDeckController;

+ (void)openDeck;
+ (void)closeDeck;

@end

//  QYHViewDeck.m

#import "QYHViewDeck.h"

@implementation QYHViewDeck

+ (instancetype)sharedInstance {
  static QYHViewDeck *viewDeckControllerWrapping = nil;
  
  static dispatch_once_t onceToken;
  dispatch_once(&onceToken, ^{
    viewDeckControllerWrapping = [[QYHViewDeck alloc] init];
  });
  
  return viewDeckControllerWrapping;
}

- (IIViewDeckController *)wrappedViewDeckController {
  self.viewDeckController = [[IIViewDeckController alloc] init];
  self.viewDeckController.centerViewController = [self createCenterViewController];
  self.viewDeckController.leftViewController = [self createLeftSideViewController];
  self.viewDeckController.rightViewController = [self createRightSideViewController];
  self.viewDeckController.panningEnabled = YES; //侧滑手势
  self.viewDeckController.delegate = self;
  
  return self.viewDeckController ;
}

+ (void)openDeck {
  IIViewDeckController *viewDeckController = [QYHViewDeck sharedInstance].viewDeckController;
  if (viewDeckController.openSide == IIViewDeckSideNone) {
    [viewDeckController openSide:IIViewDeckSideLeft animated:YES];
  }
}

+ (void)closeDeck {
  IIViewDeckController *viewDeckController = [QYHViewDeck sharedInstance].viewDeckController;
  if (viewDeckController.openSide != IIViewDeckSideNone) {
    [viewDeckController closeSide:YES];
  }
}

#pragma mark - IIViewDeckControllerDelegate

- (void)viewDeckController:(IIViewDeckController *)viewDeckController didOpenSide:(IIViewDeckSide)side {
  NSLog(@"viewDeckController--didOpenSide");
}

- (void)viewDeckController:(IIViewDeckController *)viewDeckController didCloseSide:(IIViewDeckSide)side {
  NSLog(@"viewDeckController--didCloseSide");
}

#pragma mark - Private Methods

- (UIViewController *)createCenterViewController {
    //TODO : 创建中间的视图
}

- (UIViewController *)createLeftSideViewController {
    //TODO : 创建左边的视图
}

- (UIViewController *)createRightSideViewController {
    //TODO : 创建右边的视图
}

@end

如设置左右视图的屏比例系数为0.7:
viewController.preferredContentSize = CGSizeMake(屏宽*0.7, 屏高);
