I'd like to have a slide in from bottom animation on my UITableview when the View appears. So inside the viewDidAppear Methode I created the following Animation
[UIView animateWithDuration:10.0f // for testing purposes big value
delay:0.0f
usingSpringWithDamping:0.7f // 0...1
initialSpringVelocity:0.0f
options:UIViewAnimationOptionCurveEaseOut
animations:^{
[tv_team setAlpha:1.0f];
tv_teamsVerticalConstraint.constant = 0;
[self.view layoutIfNeeded];
}
completion:^(BOOL finished) {
}
];
that works perfectly fine for the UITableView itself, however I dynamically add labels and buttons to each UITableViewCell like so
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"teamCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
//if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
//}
[cell.contentView setBackgroundColor:[[ColorSchema sharedColorSchema] color_background]];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
UIView *vw_centered = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 480, 70)];
vw_centered.autoresizingMask = (
UIViewAutoresizingFlexibleTopMargin |
UIViewAutoresizingFlexibleBottomMargin |
UIViewAutoresizingFlexibleLeftMargin |
UIViewAutoresizingFlexibleRightMargin
);
[vw_centered setBackgroundColor:[[ColorSchema sharedColorSchema] color_darkerbackground]];
[vw_centered.layer setCornerRadius:5.0f];
[vw_centered setTag:1];
//... more Labels
// Button to change the teamMembers
UIButton *btn_setPlayers = [UIButton buttonWithType:UIButtonTypeCustom];
btn_setPlayers.frame = CGRectMake(340.0, 39.0, 120.0, 19.0);
[btn_setPlayers setBackgroundColor:[[ColorSchema sharedColorSchema] color_darkgray]];
[btn_setPlayers setTag:indexPath.row];
[btn_setPlayers.titleLabel setFont:[UIFont fontWithName:#"HelveticaNeue-Light" size:9.0]];
[btn_setPlayers setTitleColor:[[ColorSchema sharedColorSchema] color_orangeSolid] forState:UIControlStateNormal];
[btn_setPlayers setTitle:#"Change Team Members" forState:UIControlStateNormal];
[btn_setPlayers addTarget:self action:#selector(changeTeamMembers:) forControlEvents:UIControlEventTouchUpInside];
[btn_setPlayers.layer setCornerRadius:5.0f];
[vw_centered addSubview:btn_setPlayers];
[cell.contentView addSubview:vw_centered];
return cell;
}
problem is, that the created button slides in from the left until it reaches the frame location on the second, third, ... cell (not the first - probably because thats the prototype cell)
How can I stop that animation?
im running xcode 6 ios 8.1
You can avoid unwanted animations by wrapping the changes in performWithoutAnimation:
[UIView performWithoutAnimation:^{
// changes
}];
So try setting your button's frame in one of these.

I would like to resize my tableView cell when the user selects a row, the cell becomes smaller then larger again. This is what I have tried so far:
#pragma mark UITableView Delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
// My animation
cell.contentView.transform = CGAffineTransformMakeScale(0.95,0.95);
cell.contentView.alpha = 1.f;
[UIView beginAnimations:#"button" context:nil];
[UIView setAnimationDuration:0.2];
cell.contentView.transform = CGAffineTransformMakeScale(1,1);
cell.contentView.alpha = 1.0f;
[UIView commitAnimations];
}
This is my tableView data source:
#pragma mark UITableView Datasource
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
// Set up cell
static NSString *cellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
cell.backgroundColor = [UIColor clearColor];
cell.textLabel.font = [UIFont fontWithName:#"HelveticaNeue" size:21];
cell.textLabel.textColor = [UIColor whiteColor];
cell.textLabel.highlightedTextColor = [UIColor lightGrayColor];
cell.selectedBackgroundView = [[UIView alloc] init];
}
// Images in my cell
NSArray *images = #[#"Songs", #"Albums", #"Artists", #"Playlists"];
UIImageView *cellImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:images[indexPath.row]]];
cellImage.frame = CGRectMake(0, 0, 90, 90);
[cell addSubview:cellImage];
return cell;
}
But this does not work. The image in the cell simply stays the same size. Any ideas? Thanks.
I seriously advise going with a UICollectionView for something like this. With it, you only have to call performBatchUpdates and you can put any frame setting inside of it's block. It's practically magic!
I don't know if you can or should do what you ask about, but if you can it would probably be with a custom UITableViewCell. But, you might be able to fake it with a custom cell, maybe with a UIView that holds all the cell's contents. The UIView would animate inside the cell, and if you are not showing separators on the table it could look like the cell itself is animating. So basically you're hiding the actual cell, and using a UIView in the cell to simulate animating the cell. Maybe like this:
[UIView animateWithDuration:0.25 delay:0 options:UIViewAnimationOptionBeginFromCurrentState animations:^{
self.customCell.frame = CGRectMake(110, 20, 100, 20);
} completion:^(BOOL finished) {
[UIView animateWithDuration:SLIDE_TIME delay:0 options:UIViewAnimationOptionBeginFromCurrentState animations:^{
self.customCell.frame = CGRectMake(0, 0, 320, 60);
} completion:^(BOOL finished) {
}];
}];
I use custom cell on UITableView using QuickDialog
In this custom cell I have several UILabel, UIImageView and a button which has the cell size and display on the top of the others subviews.
I want this button handle touch envent and call a selector. But even though the button is at the top position, the touch event does not trigger when I touch a subview.
- (UITableViewCell *)getCellForTableView:(QuickDialogTableView *)tableView controller:(QuickDialogController *)controller
{
UITableViewCell *cell = [super getCellForTableView:tableView controller:controller];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
cell.selectionStyle = UITableViewCellSelectionStyleNone;
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = cell.frame;
[btn setEnabled:YES];
[btn setExclusiveTouch:YES];
[btn setBackgroundColor:[UIColor blueColor]]; // To check if the button is at the top position
[btn setStringTag:labelIdText];
[btn addTarget:self action:#selector(handleTap:) forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:label1];
[cell addSubview:label2];
[cell addSubview:image1];
[cell addSubview:image2];
[cell addSubview:btn];
cell.userInteractionEnabled = YES;
return cell;
}
The selector :
- (IBAction)handleTap:(id)sender
{
NSLog(#"CELL TAPPED : \n");
}
Thanks a lot.
EDIT :
New version of the code :
- (UITableViewCell *)getCellForTableView:(QuickDialogTableView *)tableView controller:(QuickDialogController *)controller
{
UITableViewCell *cell = [super getCellForTableView:tableView controller:controller];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
cell.selectionStyle = UITableViewCellSelectionStyleNone;
UIView *top = [[UIView alloc] initWithFrame:CGRectMake(0, 0, cell.frame.size.width, cell.frame.size.height)];
UITapGestureRecognizer *singleFingerTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleSingleTap:)];
[top setStringTag:labelIdText];
[top addGestureRecognizer:singleFingerTap];
[cell.contentView addSubview:label_1];
[cell.contentView addSubview:label_2];
[cell.contentView addSubview:image_1];
[cell.contentView addSubview:image_2];
[cell.contentView addSubview:top];
cell.userInteractionEnabled = YES;
image_1.userInteractionEnabled = YES;
image_2.userInteractionEnabled = YES;
return cell;
}
The selector :
- (void)handleSingleTap:(UITapGestureRecognizer *)recognizer
{
NSLog(#"CELL TAPPED : \n");
}
The event is handle when I touch the text containing in the UILabel.
But it's still don't work with the UIImageView despite userInteractionEnabled setted to YES for the images.
Thanks again.
It seams you are assigning to the button the cell frame and then add it to the cell itself. In this way the position of the button is not the one you expect, and even though you can see the button it will not respond to touch because it resides outside the cell bounds.
Try to change this:
btn.frame = cell.frame;
to this:
btn.frame = cell.bounds;
Also when working with UItableViewCell remember to add subviews to its contentView and not the cell itself:
[cell.contentView addSubview:aCustomView];
I have added 2 button in a row of table view, for all the rows, and these button clicked as it first time appear in table view , when I scroll the table list the button tapping disable,
here is my code
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"ImageOnRightCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell.selectionStyle = UITableViewCellSelectionStyleGray;
cell.userInteractionEnabled = NO;
UIButton *finalPriceBtn=[UIButton buttonWithType:UIButtonTypeCustom];
UIButton *finalPriceBtn1=[UIButton buttonWithType:UIButtonTypeCustom];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
int i=indexPath.row;
finalPriceBtn.backgroundColor=[UIColor redColor];
finalPriceBtn.tag=MAINLABEL_TAG;
finalPriceBtn.frame = CGRectMake(200, 0.0, 100, 50);
[finalPriceBtn addTarget:self action:#selector(goBtnClk:) forControlEvents:UIControlEventTouchUpInside];
finalPriceBtn.titleLabel.font=[UIFont systemFontOfSize:12];
finalPriceBtn.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight;
[finalPriceBtn setImage:[UIImage imageNamed:#"man.jpg"] forState:UIControlStateNormal ];
[cell.contentView addSubview:finalPriceBtn];
finalPriceBtn1.backgroundColor=[UIColor redColor];
finalPriceBtn1.tag=SECONDLABEL_TAG;
finalPriceBtn1.frame = CGRectMake(50.0, 0.0, 80.0, 45.0);
[finalPriceBtn1 addTarget:self action:#selector(goBtnClk:) forControlEvents:UIControlEventTouchUpInside];
finalPriceBtn1.titleLabel.font=[UIFont systemFontOfSize:12];
finalPriceBtn1.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight;
[finalPriceBtn1 setImage:[UIImage imageNamed:#"bulk-female.jpg"] forState:UIControlStateNormal ];
[cell.contentView addSubview:finalPriceBtn1];
}
else
{
finalPriceBtn = (UIButton *)[cell.contentView viewWithTag:MAINLABEL_TAG];
finalPriceBtn1 = (UIButton *)[cell.contentView viewWithTag:SECONDLABEL_TAG];
}
return cell;
}
It is happening because, each time you are scrolling the tableview, your cells are reused and in that case cell is not nil and the code above the code before the cell==nil, makes the userInteractionEnabled to NO. That's why, your button is not clickable.
First time those buttons are clickable because they were not allocated, I mean the cell was not allocated and setting any attribute to non-allocated entity makes no effect. Hope you got the point.
I'm trying to add subviews to a view according to the cell of the tableview .. i've done this code already
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
VerseCell *cell = (VerseCell *)[tableView cellForRowAtIndexPath:indexPath];
rowSelected = indexPath.row;
CGRect cellRect = cell.frame;
UIView *cellView =[[UIView alloc]initWithFrame:CGRectMake(cellRect.origin.x+4, cellRect.origin.y+15, cellRect.size.width-20, 70)];
UIImageView* background =[[UIImageView alloc]initWithImage:[UIImage imageNamed:#"FavoritePanelBackground"]];
background.frame =CGRectMake(cellRect.origin.x+4, cellRect.origin.y+15, cellRect.size.width-20, 70);
[cellView addSubview:background];
[cellView setBackgroundColor:[UIColor redColor] ];
UIButton * favoritsB = [[UIButton alloc]initWithFrame:CGRectMake(cellRect.origin.x+10, cellRect.origin.y+15, 60, 40)];
[favoritsB setBackgroundImage:[UIImage imageNamed:#"MofadalatNormalIcon.png"] forState:UIControlStateNormal];
[favoritsB setBackgroundImage:[UIImage imageNamed:#"MofadalatTappedIcon.png"] forState:UIControlStateHighlighted];
[favoritsB addTarget:self action:#selector(favorite) forControlEvents:UIControlEventTouchUpInside];
[cellView addSubview:favoritsB];
cellView=nil;
}
the problem is .. that this code work as expected in the first row only.. and when click on next cell it shows the main UIVIew (which i've mark with red background) in the expected position while the sub views of it is going really far down... so what i'm doing wrong here.. and is there another approach for what i'm doing if that will not work?
Where are you trying to add these view? Inside the table view cell? If so, you never add cellView as a subview of cell. IF that's what you're trying to do, add this line just above cellView = nil:
[cell addSubview:cellView];
I've tried a bunch of stuff - adding a button from the object browser, changing attributes, searching the web, but no luck. Essentially, I'd like to do --in the storyboard--:
where you see "add to contacts" "share location" and "add to bookmarks".
You should create a UITableViewCell whose contentView holds 3 separate UIButtons.
To do this programmatically, in your tableView:cellForRowAtIndexPath: data source method, you can use code similar to the following:
- (UITableViewCell*) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString* identifier = #"cell";
UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil];
cell.backgroundColor = [UIColor clearColor];
UIButton* button1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
UIButton* button2 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
UIButton* button3 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button1.frame = UIEdgeInsetsInsetRect(cell.contentView.bounds, UIEdgeInsetsMake(0, 0, 0, 250));
button2.frame = UIEdgeInsetsInsetRect(cell.contentView.bounds, UIEdgeInsetsMake(0, 125, 0, 125));
button3.frame = UIEdgeInsetsInsetRect(cell.contentView.bounds, UIEdgeInsetsMake(0, 250, 0, 0));
button1.autoresizingMask = UIViewAutoresizingFlexibleRightMargin;
button2.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleLeftMargin;
button3.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin;
[cell.contentView addSubview:button1];
[cell.contentView addSubview:button2];
[cell.contentView addSubview:button3];
}
return cell;
}
Also, in the tableView:willDisplayCell: method of your delegate, do the following to have the default decoration of the cell totally disappear:
- (void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
cell.backgroundView = nil;
}
You should obtain a result very similar to what you posted.
Put the three buttons in a UIView that is 320 pixels wide and say 60 hight, and make that view the footer of your table.
The UITableView is styled using the UITableViewStyleGrouped stye.
The three UIButtons are programmatically added to the tableView.tableFooterView.
Alternatively, you can add three UIButtons to the contentView of the last cell.
Add buttons like:
UIButton *theButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
theButton.frame = CGRectMake(20, 20, 200, 40);
[theButton setTitle:#"Button" forState:UIControlStateNormal];
[theButton addTarget:self action:#selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:theButton];
Get the button positions correctly using trial and error :)
