Is there any way to decrease the standard width of grouped UITableViewCell and put a custom button on the left side(outside of cell boundary)? I tried to change the cell size but it keeps same
You are going to have to fake the editing mode.
What I mean by that is that as AtomRiot said you have to subclass UITableViewCell so that when in editing mode you show the button you want on the left, outside the cell.
But first things first.
To change the indentation level for your cells all you need to do is implement this delegate method for the UITableView
- (NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath
So that takes care of it. Then in your UITableViewCell subclass all I would do is to implement the method
- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
which I assume is called when the table the cell belongs to has changed to editing mode.
There I would fade in (or animate in any way you want) a button to appear on the left of your cell.
I have done it inside a grouped-style cell but never on the outside.
Give it a try!
You could subclass UITableCell and add your own custom views inside of it. I have not personally added a button inside one but it should work. It may get confused with the row selected call the tableview makes if you are implementing that.
The Cocoanetics blog seems to have a pretty good solution to this:

I know this question has been asked before but I couldn't find an answer that applied to my problem.
I've got a UITableViewController that has a third row that is filled with a UITextView.
I'm quite happy with the way it looks and the way text is typed into it.
However I'm unable to find a way of getting rid of the keyboard once the user is done entering text. I'd like to be able to use the return button for actual \n in the text.
I've gotten this far that pressing the upper two rows will make the textView te resignFirstTransponder but is there a way to catch a tap on the greyish background?
This is all in a UITableViewController loaded from a nib file.
Btw, I'm quite new to iOS programming so the more elaborate your answer the better :)
Thanks!
A pattern many apps follow is to show a horizontal bar with buttons on it just above the keyboard. It can contain a done button clicking on which you can hide the keyboard. And of course you will have to create that horizontal view yourself.
Another way would be to enable a touch recognizer elsewhere, and on a tap outside hide the keyboard
One alternative would be to add a toolbar to the keyboard with something like a "done" button that will dismiss it. You can find some sample code about that here. One second approach would be to dismiss the keyboard when the user selects a different cell or even when the tableView scrolls. In order to do that, you can add relevant code in -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath or in -(void)scrollViewDidScroll:(UIScrollView *)scrollView respectively.
This can get a little tricky if your new at iOS. The way I handle a UITextView in a UITableViewCell is I make a custom UITableViewCell subclass with an outlet for the UITextView.
Then set your cell in interface builder to be of that subclass. In the CellForRowAtIndexPath:
set the delegate to self. Then in the DidSelectRowAtIndexPath you call the delegate for the TextView based on the indexPath, this way the keyBoard will dismiss for the correct row if you touch the background. If you want it to dismiss when the user touches any cell just call the delegate without specifying the indexPath. The Delegate is TextViewShouldEndEditing:.Ill post some code if you want.
I have a TableView with one cell and I want to insert in this cell a lot of text so I think I'll need to use a ScrollView for scroll the text.
How can I insert? Is correct this method?
This is a help in the application, is correct use this modality?
Sorry but I'm a beginner and I don't have an iPhone or iPod, thanks!
While I concur with 7KV7's original comment, it doesn't look like there is need of a tableview in this scenario...
Just in case someone else happens upon this looking for an answer to the "Scrollview in a Tableview" question here are few clarifying points for the above comments.
The technical problem with having a tableview and a scrollview together on the same view is that UITableView is already a descendent of UIScrollView and if you attempt to handle both in the same view then you will end up with quite a mess with conflicting delegate messages.
As suggested by iPhonePgr, you can create a custom UITableViewCell. The first thought would be to let the UITableViewCell act as the delegate for it's own scroll view. The problem here is that the cell and it's contents could be discarded or reused at any moment as part of tableview's dequeue functionality.
So some ground rules to guide your implementation:
Whatever your solution, you're probably going to end up making a custom controller class, possibly derived from NSObject and implementing UIScrollViewDelegate.
The custom controller object acts as the mediator between the model object and the cell.
You will probably have an array or array-of-arrays that mirrors the model hierarchy driving the UITableView structure.
Because the cells can be discarded at any time you will have restore the scroll view state on cell initialization and preserve the state has part of handling your delegate actions or through a custom UITableViewCell implementing prepareForReuse.
Hopefully these points will come in useful to anyone who runs across this entry.
You need to create a custom cell by inheriting UITableViewCell and then add UIScrollView in the customcell. Then Use that cell in the Table view.
you can put your text in UITextView and add it as a subview in your UITableViewCell,because
UITextView is inherited from UIScrollView,
No need to add UIScrollView if you use UITextView
When you create UITableView you implement a number of delegate method which you can see by pressing the window key and then double clicking the UITableView delegate . In one of the methods you can set the cell height as per your requirement. By doing this your cell height can vary.
- (CGFloat)tableView:(UITableView *)resultTableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 150;
}
As your table has a defined height, when the text in cell will be too much to contain into a scrollview will be automatically inserted.
I got a kind of problem. At this point I have made a custom tableviewcell, nothing fancy just two labels with 1px white shadow beneath the text. The problem is that when the user (me) select a cell the blue highlighting looks really awkward because of the shadow. So I need to disable/remove the shadow on highlighting.
I have not found any methods which are being called once the user selects the row, just after the user removes his finger.
So at this point I need to subclass UITableViewCell just to write two lines of code in the setSelected-method that does it. Are there any better ways to do this? And yes, I just add views to the contentView property of the cell.
And what is the layoutSubviews-method for? I don't find it in documentation but obviously it is in the iOS so...When does it get called and in what context?
Because when I subclass a UITableViewCell, what should I do with the sizes of the view-components?
Thanks in advance!
The below method is called just before the user is about to select the row....
- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
I am looking for the most direct way to make it so that when the user taps a UITableViewCell, a keyboard appears. I want to use a custom keyboard (UIPickerView) and I preferably would like to make the cell style UITableViewCellStyleValue2. I can't seem to find a very direct way of doing this. I have a navigation bar on top, and hoping to make the buttons on that change as well...
Thanks!
First and foremost, to achieve this you're going to have to handle the custom animation of the UIPickerView sliding up and down. They keyboard is handled automatically by the controls that automatically need it (UITextField, UITextView, etc.).
So when your view loads you will want to create and configure your picker and then move its Y coordinate to CGRectGetMaxY([[UIScreen mainScreen] applicationFrame]);
Then in your - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath you will call a method that is responsible for animating your picker view into place. The only problem I foresee with this approach is allowing the user to dismiss this picker view in a way that makes sense as users are used to input views sliding only when they're needed (meaning that they appear when a view becomesFirstResponder and they disappear automatically when that view resignsFirstResponder status).
I think I understand what you're trying to achieve here and I would do it a bit differently. Instead of displaying a picker with options when you select a cell I would instead push a new tableViewController with your options laid out as cells. Then when the user makes a selection, you can set a checkmark and pop back to the original view.
I am display some long text in a cell, and resizing the height of the cell using heightForRowAtIndexPath. However, when the text is displayed it is running into the area used by the (blank) disclosure indicator.
When such a row is selected, and the checkmark is displayed, the text reformats itself to not use the indicator area, causing a visual effect I do not want.
If there was a UITableViewCellAccessoryBlank accessory type (rather than UITableViewCellAccessoryNone), maybe the text wouldn't wrap into that area when displaying. Am I going to have to create a custom cell and layout my own label, or is there a simpler way?
First of all, I don't see a property call UITableViewCellAccessoryBlank in the UITableView Cell class reference so I don't think this will work.
I think you have 2 options :
Create a custom cell, like you suggest.
Configure the textLabel of your cell to change his contentMode.
I read this in UILabel class reference :
The default content mode of the
UILabel class is
UIViewContentModeRedraw. This mode
causes the view to redraw its contents
every time its bounding rectangle
changes. You can change this mode by
modifying the inherited contentMode
property of the class.
I suppose that the textLabel bounds change every time you change the accessory type, so by default it redraw himself.
You can try this in your - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath method :
cell.textLabel.contentMode = UiViewSomeContentMode;
Content mode list can be found here. I'm not sure which one you should use so I let you try.
EDIT
It seems that contentMode is not working. So you should use a custom UITableViewCell to prevent any animation when adding an accessoryView.
Hope this helps !
