1. Implementation idea of popup menu that supports expansion and folding:

1.1 Add popup view to keyWindow and mask to main window (the main reason is to hide the popup view by clicking on a blank area of the screen)

1.2 When displaying, the animation extends from the upper right corner to the lower left foot; When hidden, the animation retracts from the bottom left foot to the top right corner (when displayed, it grows from top down, i.e. X,y)

1.3 The layout of the internal view is collectionView

1.4 The frame of view is calculated and transformed according to the commodity cell where the menu button is currently clicked.

/** Triggers the collapse menu to hide and show the button */
@property (nonatomic.weak) UIButton *btn;

/** is used to calculate the folding menu frame, */
@property (nonatomic.weak) UIButton *tmpbtn;

Copy the code

2. Application scenario of horizontal pop-up menu view:

2.1 Supported functions of goods in stores: expand the view horizontally to the right (operation: down/on the shelf, print, edit, synchronize the network) and fold the hidden view again

2.2 Online goods currently only include the function of taking off: Expand the folding view: (including the function of taking off/taking off goods)

3. Vertical popup menu view

I. The implementation idea of the pop-up menu that supports expansion and folding

1.1 Add popup view to keyWindow and mask to main window (the main reason is to hide the popup view by clicking on a blank area of the screen)

 #define kWindow [UIApplication sharedApplication].keyWindow
 
 [kWindow addSubview:self];

 [kWindow addSubview:self.cover];// Add a mask to the main window that listens for click events to hide the popup view


Copy the code

1.2 a

When shown, the animation extends from the upper right corner to the lower left foot; When hidden, the animation retracts from the bottom left foot to the top right corner (when displayed, it grows from top down, i.e. X,y)

Implementation principle of expansion effect:

1. When clicking the pop-up button above the cell displaying product information, the shadow alpha changes from 0 to 1, and the scale of the popover changes from 0 to 1 (CABasicAnimation is used here).

2 Click on the blank area (selsel. cover), and then change the shadow alpha from 1 to 0 and the popover scale from 1 to 0 (again using CABasicAnimation). Remove the shadow and popover when the animation is complete

1.3 The layout of the internal view is collectionView

@property (strong.nonatomic) UICollectionView *collectionView;

Copy the code

1.4 The frame of view is calculated and transformed according to the commodity cell where the menu button is currently clicked.

     CGRect endRect = [weakSelf.btn.superview convertRect:weakSelf.btn.frame toView:kWindow];
     CGRect Rect = [weakSelf.tmpbtn.superview convertRect:weakSelf.tmpbtn.frame toView:kWindow];
     // Set the menu frame
     weakSelf.models.rect = Rect;
     weakSelf.models.endRect =   endRect;// End position
     
     
     [[[weakSelf models].viewModel            expandMenuSubject] sendNext:weakSelf.models];
 }];

Copy the code

II, usage,

2.1 Create popmenuView

1. Build the data model inside the menu

+ (NSMutableArray*)getMenudatas4MiniAppWithBlock:(void(^) (id sender))block{
        
   NSMutableArray* tmp = [NSMutableArray array];
    QCTCollectionModel *network = [QCTCollectionModel new];
    network.titleName =  QCTLocal(@"Shelves_key");
    
    network.imgName= @"icon_sp_shangjia";
    network.block = block;
    network.type =QCTCollectionModelType4Shelves;
        
    [tmp addObject:network];
    
    return tmp;
    
}

Copy the code

1.2 When displaying, the animation extends from the upper right corner to the lower left foot; When hidden, the animation is recovered from the lower left foot to the upper right corner (when displayed, it is from the top down, that is, X and Y gradually become larger). 1.3 Internal view adopts collectionView for layout. 1.4 The frame of view is calculated and transformed according to the commodity cell where the menu button is currently clicked.

2. Application scenario of horizontal pop-up menu view:

2.1 Supported functions of goods in stores: expand the view horizontally to the right (operation: down/on the shelf, print, edit, synchronize the network) and fold the hidden view again

2.2 Online goods currently only include the function of taking off: Expand the folding view: (including the function of taking off/taking off goods)

Similar Popup menu in this APP: the drop-down menu (vertical) in the upper right corner of the membership module. Scenario: 0.1.

Add view to keyWindow #define kWindow [UIApplication sharedApplication]. KeyWindow [kWindow addSubview:self]; #define kWindow [UIApplication sharedApplication]. [kWindow addSubview:self.cover]; 2. Expand effect: When displaying, the animation extends from the upper right corner to the lower left foot; When hidden, the animation is withdrawn from the lower left foot to the upper right corner // (when displayed, the animation is displayed from the top down, that is, X and Y gradually become larger) When I click on the Eject button, the shadow alpha goes from 0 to 1, and the popover scale goes from 0 to 1 (CABasicAnimation). Click on the blank area, and then make the shadow alpha go from 1 to 0, and the popover scale goes from 1 to 0 (also CABasicAnimation). 4.

3.4 Integrating into the Cell

Fans wonder if it can be used in cell click events

A: yes, please refer to the examples in this paper, the integration of QCTQCTgoodsListTableViewCellView

You can also control the click priority using the cancelsTouchesInView attribute. Case: iOS Settings of the tableView click priority is lower than the cell selected events [scene: screening of view, for example, to monitor the click event of the mask is hidden screening view 】 blog.csdn.net/z929118967/…

    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] init];
    [[tap rac_gestureSignal] subscribeNext:^(id x) {
        @strongify(self);
        if (self.alpha) {
            [self.viewModel.hiddenSubject sendNext:nil]; }}]; [self addGestureRecognizer:tap];
    
    UITapGestureRecognizer *cutTap = [[UITapGestureRecognizer alloc] init];
    cutTap.cancelsTouchesInView = NO;// Set the click event priority of the tableView lower than the selected event of the cell
    [[cutTap rac_gestureSignal] subscribeNext:^(id x) {
        // @strongify(self);
        [self.viewModel.hiddenSubject sendNext:nil];

    }];
    [self.tableView addGestureRecognizer:cutTap];
