UIButton touchUpInside conflicts with UITableViewCell swipe event - ios

I am displaying swipe button in UITableViewCell as follows :
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
- (nullable NSArray<UITableViewRowAction *> *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewRowAction *cancelAction;
UITableViewRowAction *editAction;
UITableViewRowAction *messageAction;
cancelAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:#"Cancel" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath){
[tableActivities setEditing:NO];
}];
cancelAction.backgroundColor = [UIColor blueColor];
editAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:#"Edit" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath){
[tableActivities setEditing:NO];
}];
editAction.backgroundColor = [UIColor greenColor];
messageAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive title:#"Message" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath){
[tableActivities deleteRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
}];
return #[messageAction, cancelAction, editAction];
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
}
In the cell's contentView, I have placed a UIButton which has a UIControlEventTouchUpInside controlEvent.
When I swipe the cell by touching the button area, both the swipe and UIButton event are fired.
How can I control this ?


You can solved your problem by checking isEditing property of UITableView in your button action like this
- (void)btnTap:(UIButton*) sender {
if (!self.tableActivities.isEditing) {
//Perform Action
}
}

Show multiple data, after swipe in tableview cell

I am having a table view with some datas. While on left swipe of cell i want 'Delete' and 'Edit'. I got 'Delete' by using the below code. Please help me to solve this..
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.section == 0) {
return NO;
}
return YES;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
[self.circleGroupArray removeObjectAtIndex:indexPath.row];
[_myCircleTableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
}
}

Use this method in your class, If you want more actions you can create more UITableViewRowActions and add them to array.
-(NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewRowAction *editAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:#"Clona" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath){
//add edit action here
}];
editAction.backgroundColor = [UIColor blueColor];
UITableViewRowAction *deleteAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:#"Delete" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath){
//add delete action here
}];
deleteAction.backgroundColor = [UIColor redColor];
return #[deleteAction,editAction];
}

Reset UITableViewCell position

-(NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath {
Course *c = self.courses[indexPath.row];
UITableViewRowAction *button = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#" - " handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
[c remove];
[tableView beginUpdates];
[tableView reloadRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationNone];
[tableView endUpdates];
}];
button.backgroundColor = [UIColor red];
return #[button];
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
// you need to implement this method too or nothing will work
}
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES; //tableview must be editable or nothing will work...
}
How do I reset the position of my cell after the action has been pressed? Currently I'm reloading the cell but this ends up giving the cell a jumpy animation.

Disappearing editActionsForRowAtIndexPath actions

I want to implement editActionsForRowAtIndexPath to display several options when I left-swipe a cell in my UITableview. So I used this code:
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
//Obviously, if this returns no, the edit option won't even populate
return YES;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
//Nothing gets called here if you invoke `tableView:editActionsForRowAtIndexPath:` according to Apple docs so just leave this method blank
}
-(NSArray *)tableview:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewRowAction *delete = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Delete" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// Delete code here
}];
UITableViewRowAction *changeAmt = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Amt" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// popover amount change code
}];
changeAmt.backgroundColor = [UIColor colorWithRed:0.022 green:0.541 blue:0.001 alpha:1.00];
UITableViewRowAction *changeAcct = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Acct" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// popover account change code
}];
changeAcct.backgroundColor = [UIColor colorWithRed:1.000 green:0.492 blue:0.000 alpha:1.00];
UITableViewRowAction *viewTrans = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"View" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// Push to view
}];
viewTrans.backgroundColor = [UIColor colorWithRed:0.002 green:0.342 blue:0.710 alpha:1.00];
return #[delete,changeAmt,changeAcct,viewTrans]; //array with the buttons delete, changeAmt, changeAcct, viewTrans
}
Yesterday, this code produced this result:
Today, I decided to eliminate the viewTrans action by modifying the editActionsForRowAtIndexPath method like this:
-(NSArray *)tableview:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewRowAction *delete = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Delete" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// Delete code here
}];
UITableViewRowAction *changeAmt = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Amt" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// popover amount change code
}];
changeAmt.backgroundColor = [UIColor colorWithRed:0.022 green:0.541 blue:0.001 alpha:1.00];
UITableViewRowAction *changeAcct = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Acct" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// popover account change code
}];
changeAcct.backgroundColor = [UIColor colorWithRed:1.000 green:0.492 blue:0.000 alpha:1.00];
// UITableViewRowAction *viewTrans = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"View" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
// {
// // Push to view
// }];
// viewTrans.backgroundColor = [UIColor colorWithRed:0.002 green:0.342 blue:0.710 alpha:1.00];
return #[delete,changeAmt,changeAcct]; //array with the buttons delete, changeAmt, changeAcct, viewTrans
}
This modified code had the effect, somehow, of removing all the actions except the default Delete action:
So I uncommented the code, and replaced the reference to the viewTrans action in the return line. The extra actions do not reappear.
This is the only code I modified. Anybody have any idea what I did wrong?

I had been working on your question and initially, I can't get editActionsForRowAtIndexPath method called but later I found a little problem and maybe is the same for you, the declaration for the method
-(NSArray *)tableview:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
is not right, the correct is
- (nullable NSArray<UITableViewRowAction *> *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
so my method stay like this
- (nullable NSArray<UITableViewRowAction *> *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewRowAction *delete = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Delete" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// Delete code here
}];
UITableViewRowAction *changeAmt = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Amt" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// popover amount change code
}];
changeAmt.backgroundColor = [UIColor colorWithRed:0.022 green:0.541 blue:0.001 alpha:1.00];
UITableViewRowAction *changeAcct = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Acct" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
// popover account change code
}];
changeAcct.backgroundColor = [UIColor colorWithRed:1.000 green:0.492 blue:0.000 alpha:1.00];
//UITableViewRowAction *viewTrans = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"View" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
// {
// Push to view
// }];
//viewTrans.backgroundColor = [UIColor colorWithRed:0.002 green:0.342 blue:0.710 alpha:1.00];
return #[delete,changeAmt,changeAcct]; //array with the buttons delete, changeAmt, changeAcct, viewTrans
}
And this is how it looks
I hope this helps you

TableView Cell button click and swipe gesture mix issue

I have implemented tableview with swipe for delete and flag purpose.
But when i swipe right to left then other button(apart from swipe) click called randomly.
Please help me .
These are the following code.
-(NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewRowAction *button = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Button 1" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
}];
button.backgroundColor = [UIColor greenColor]; //arbitrary color
UITableViewRowAction *button2 = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:#"Button 2" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
{
}];
button2.backgroundColor = [UIColor blueColor]; //arbitrary color
return #[button, button2];
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
}
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}

add gesture delegate in your code and check class of gesture recognizer
- (BOOL)gestureRecognizer:(UIGestureRecognizer )gestureRecognizer shouldReceiveTouch:(UITouch )touch

UITableViewRowAction change backgroundcolor on press

I created an instance of UITableViewRowAction in
-(NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
and I have a handler block when this row action is triggered:
handler:^(UITableViewRowAction *action, NSIndexPath *indexPath)
You have a row action parameter that can be used so you do not create retain cycles and you have an index path. I've tried setting the backgroundColor of that new row action like this:
[action setBackgroundColor:[UIColor greenColor]];
But this did not change anything. I also tried setNeedsDisplay on the button object of the row action, but without any luck.
Any idea how I can change the backgroundColor while the row actions are still visible? Thanks

Here is my implementation of the same and it works well. It should solve your problem as well..
- (NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewRowAction *one = [UITableViewRowAction rowActionWithStyle:0 title:#"one" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
NSLog(#"my first action");
}];
UITableViewRowAction *two = [UITableViewRowAction rowActionWithStyle:1 title:#"two" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
NSLog(#"my second action");
}];
UITableViewRowAction *three = [UITableViewRowAction rowActionWithStyle:1 title:#"three" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
NSLog(#"my third action");
}];
one.backgroundColor = [UIColor purpleColor];
two.backgroundColor = [UIColor greenColor];
three.backgroundColor = [UIColor brownColor];
return #[one, two, three];
}
