How to change the width of the UITableViewCell? - ios

Question

I am working on a UITableView which has a SwipeGesture.
On Swipe, the Cell should Swipe Left and the objects which are set at 320 should appear

Answer 1

Place them in the contentView of the UITableViewCell and make an animation on the contentView that changes the frame to x = -320 and it will work.

Answer 2

UITableView change the frame of cells when they are added to the table view. If you want to change the width of a cell, you should either change the width of the table, or change the width of the contentView in the cell.
A better way to achieve this is subclassing UITableViewCell and overriding its -setFrame: method like this:
Try this one:
- (void)setFrame:(CGRect)frame
{
frame.origin.x += inset;
frame.size.width -= 2 * inset;
[super setFrame:frame];
}

Answer 3

Try the below code.
// Create the swipe view
//Change the frame as per your requirement
UIView* _swipeView = [[UIView alloc] initWithFrame:CGRectMake(5, 5, 10, 70)];
//setting the background
[_swipeView setBackgroundColor:[UIColor redColor]];
[_swipeView setTag:1896];
[cell.contentView addSubview:_swipeView];
// Create the gesture recognizers
UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(didSwipeRightInCell:)];
[swipeRight setDirection:UISwipeGestureRecognizerDirectionRight];
UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(didSwipeLeftInCell:)];
[swipeLeft setDirection:UISwipeGestureRecognizerDirectionLeft];
[cell addGestureRecognizer:swipeRight];
[cell addGestureRecognizer:swipeLeft];

-(void) didSwipeRightInCell:(UISwipeGestureRecognizer*)ges{
UITableViewCell* cellViewInProgress_ = (UITableViewCell*)ges.view;
for(UIView* view in cellViewInProgress.contentView.subviews)
{
if(view.tag == 1896){
[UIView animateWithDuration:0.5 animations:^{
//Change the frame as per your requirement
view.frame = CGRectMake(5, 5, 220, 70);
}];
// I have placed UILabel you can try your own control
//Change the frame as per your requirement
UILabel *lblDemo = [[UILabel alloc] initWithFrame:CGRectMake(10, 20, 200, 30)];
[lblDemo setFont:[Support getAppFontSemiBold:16.0]];
[lblDemo setTextColor:[UIColor whiteColor]];
[lblDemo setBackgroundColor:[UIColor clearColor]];
lblDemo.tag = 2341;
[lblDemo setText:#"Hello"]];
[view addSubview:lblDemo];
}
}
}
