I am new to iOS. I need to show the Label in timeDelay in UITableViewCell only when its visible?
Create a custom UITableView cell. In your cellForRowIndexPath, call the function performSelectorWithDelay which will show your UILabel.
When the cellForRowIndexPath is called, it's pretty certain that the cell will now be shown.

When the user taps the accessory view, the profile image in the UITableViewCell gets darkened by a black view that gets added on as a subview.
Here is what the cell looks like with the black subview:
Here's the issue: When I tap on another cell, the subview gets removed from the first cell and added to the second:
I would like to keep the subview for all cells that have been tapped.
Here is the code in which I handle that functionality:
self!.profileImageBlackView.cornerRadius = cell.followUserImage.frame.height/2
self!.profileImageBlackView.frame = cell.followUserImage.frame
cell.followUserImage.addSubview(self!.profileImageBlackView)
cell.followButton.hidden = false
For some reason, the follow button gets added to both cells, but the "profileImageBlackView" gets moved from cell to cell depending upon which one was activated.
You cannot display the same view in different cells. If you add the view to another cell it's removed from the first one. You must create a separate view for each cell.
I developed custom cell. which have one UITextfield. i want to clear textfield text on UIButton event. UIButton is also in tableView in another section.

I have a UICollectionView in every UITableViewCell of my UITableView.
The program should perform a segue there is a click on the UITableViewCell but the cell is clickable just out of the UICollectionView.
It is clickable just in the red portions.
Do you have any ideas?
You need to disable user interaction in each collection view:
In your storyboard uncheck here:
Or in your cellForRowAtIndexPath:
cell.collectionView.userInteractionEnabled = NO;
I have a UIViewController with a calendar and below it is a UITableView with a UITableViewCell that has a series of UIButtons that I change the button text depending on the data that I retrieve. When a date is selected I update a NSArray and call [self.tableView reloadData]. The first row populates as it should, the UIButton titles show the correct data. The rest of the rows show the default values for the UIButtons from the storyboard. If I scroll a cell off the screen and let it come back it displays the correct data (i.e. updates the titles of the UIButtons). I'm not sure why this is happening. I tried adding
[cell setNeedsLayout] before the cell is returned but it has not helped.
Are you modifying the testLabels directly? UIButtons have iffy behavior sometimes if you do. Try using the UIButton methods to change the textLabel's properties, such as setTitle: forState:
In tableviewcells i have a buttons and webViews, with some array count.so when i tap on particular tableViewcells button action. i have to hide that particular tables cells webview?
You can do it like this, In UIButton action, you will get cell index if you've given tag to your button, using that tag, you can make cell object with NSIndexPath for the cell you've tapped, hide UIWebView subviews within that cell, you may need to set its height base on some condition which you've made in heightForRowAtIndexPath of UITableView. Another way to get the cell is, [button superview]; here you'll get containerview for particular cell, and apply the same logic, this would only work if you've added button and webview in contentview.
[cell.webView setUserInteractionEnabled:NO];
Make the webView can't get the user touch focus, so that the cell will get the user interaction : )
