Adding Gestures to Cells
cellForRowAtIndexPath:
-(UITableViewCell *)tableView:(UITableView *)theTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = @"cellIdentifier";
UITableViewCell *cell = [theTableView dequeueReusableCellWithIdentifier:cellIdentifier];
if(!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
UITapGestureRecognizer *doubleTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(didDoubleTapCell:)];
doubleTapRecognizer.numberOfTapsRequired = 2;
[cell addGestureRecognizer:doubleTapRecognizer];
return cell;
}
}
-(IBAction)didDoubleTapCell:(UITapGestureRecognizer *)sender {
UITableViewCell *cell = (UITableViewCell *)sender.view;
}
How Swiping Works
swipe - to- reveal in cells is actually quite simple
Your need two views of the same size as the cell on which is displayed when the cell is created and the other which is the view that gets revealed as the topView swipes ot
stacked on top of each other. Strictly speaking UIVews d ehavior in the photoshop senselayer bon't have
but stacking the cells mimics it
UISwipeGestureRecognizerDirectionRight
swipeView topView
UISwipeGestureRecognizerDirectionLeft
its target a method that animates the movemonent of the views by changing their frame topView starts with a frame origin of (0,0) and ends up with an orign of (320,0)
adding little visual tweaks that make the views appear to bounce as they move in and out of place
fake momentum to the animation can make it seem considerably more realistic
#import <UIKit/UIKit.h>
@interface SwipeCell:UITableViewCell
@property (nonatomic, strong) UIView *swipeView;
@property(nonatomic, strong) UIView *topView;
-(IBAction)didSwipeRightInCell:(id)sender;
-(IBAction)didSwipeLeftInCell:(id)sender;
@end
-(id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier

self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if(self) {

[_topView setBackgroundColor:[UIColor whiteColor]];
UILable *label = [[UILabel alloc]initWithFrame:CGRectMake(10,20,150,40)];
[label setFont:[UIFont fontWithName:@"Zapfino" size:18]];
[label setTextColor:[UIColor blackColor]];
[label seText:@"Swipe me!"];
[_topView addSubview:label];
UIImageView *pointImage = [[UIIMageView alloc]initWithImage:[UIIMage imageNamed:@"point"]];
_swipeView = [[UIView alloc] initWithFrame:CGRectMake(0,0,self.contentView.frame,size.width,80)];
[_swipeView setBackgroundColor:[UIColor darkGrayColor]];

[haveSwipedlabel setFont:[UIFont fontWithName:@"GillSans-Bold" size:18]];
[haveSwipedlabel setTextColor:[UIColor whiteColor]];
[haveSwipedlabel setText:@"I've benn swiped!"];
[_swipeView addSubview:avaSwipedLabel];
[self.contentView addSubview:_swipeView];

UIView's fantastically -useful block-based animation methods to move things around.
OBJECTIVE -c BLOCKS
Blocks are a feature that was introduced to objective -c in version 2.0 closures and lambas.
a number of UIView methods due for deprecation that will been replaced by block-based methods
A block is discrete chunk of code that can be passed around much like a variable. your can recognize them by the ^ operator.
BOOL (^myBlock)(int) = ^(int theVariable) {
[doSomethingWith:theVariable];
};
Blocks come into their own where you have chunks of code that need to be executed to perform tasks that are best rn asynchronously.
animations are one example, but blocks are used extensivel in other areas such as networking.
