I have a UIAlertView which is very narrow for its content.
As a result, entire message is not readable. When the message exceeds usual size, the area becomes white instead of default blue.
Also, I have 3 buttons in total. They all appear in vertical instead of horizontal line.
How can I change this?
I have very simple requirement and do not want to subclass it as far as possible.
You can not do that by the default alert view because the text area inside it is not accessible,
you have to subclass it to get what you want, read this demo to subclass the uialertview it is easy and straight to point

Right now I have a standard UITableView that is empty by default and the user can add cells to it.
I noticed this app starts with no cells and is empty (like you cant see lines) but my standard view always has the lines like standard table view.
I thought it may be a grouped table style but the edges are not curved like the grouped style is.
Does anyone have any ideas?
The lines between cells are controlled by the separatorStyle property of your tableView. To remove the lines simply set:
tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
Your other options are UITableViewCellSeparatorStyleSingleLine and UITableViewCellSeparatorStyleSingleLineEtched.
You can hide the separator lines by setting their color to the same color as your background, e.g.
tableView.separatorColor = [myApp theColorOfMyBackground]; // A UIColor object
Make sense?
The cells in your picture are likely custom cells, but you didn't really ask about that. :-)
EDIT: As noted in another answer seperatorStyle can be used to simply "turn off" the lines. That's a better way to do it.
This is a good question. +1 What app is this? Does the view you show above actually "scroll" even though only 2 rows are showing? I am wondering if it is a truly a table view. It could be a series of UIViews added to a UIScrollView with a dark background.
Assuming the programmer knows how tall the "rows" are, then they can add them with a pixel spacing over the charcoal background. With the UIScrollView, the programmer can define the contentSize.
If more views were added to extend past off the screen and the contentSize was appropriately defined, the USScrollView would automatically allow scrolling at that point.
Selecting a "row" could be easily handled by UIGesture controls on each UIView.
*EDIT
After seeing the app, Delivery by JuneCload, it is definitely using a UITableView with custom cell views. As Mark and Matt have answered.
I need to present a UIActionSheet that will show 10 buttons. When I do that on iPad, the UIActionSheet shows on a popover that is very long vertically (not aesthetically pretty). Is that possible to specify the UIActionSheet size to a maximum size?
I have tried this
myActionSheet.frame = CGRectMake(0,0,300,300);
myActionSheet.bounds = CGRectMake(0,0,300,300);
and have also tried to put these lines inside
- (void)willPresentActionSheet:(UIActionSheet *)actionSheet {
without success.
any clues?
thanks
I think this is one of the cases where you can't really use a built-in class like the UIActionSheet to accomplish your goal. I don't think it is designed to be used for cases where you have as many buttons as 10. It just doesn't scale very well, just as you have discovered.
But let's pretend that it would be possible to change the size. What should happen when you change the size? There is a minimum size for each button for it to be tapable. And you also need some space between the buttons as to not cause a misstap. So even if you could change the size it couldn't be reduced by very much. And since it's not intended to be able to change the size you would have to try and access all the buttons and resize and move them as well. One could argue that perhaps the buttons could be placed in columns but since that is not implemented it would still not help if you made the UIActionSheet any wider.
I would recommend that you either:
Create your own custom view with all 10 buttons placed just as you liked.
Use a table view to present the options. Since the table view can be scrolled you can get the size you like.
If you set modalInPopover to YES on the UIViewController you present in the popover the user must make a choice before she can move on.
try with `- (void)showFromRect:(CGRect)rect inView:(UIView *)view animated:(BOOL)animated
because in apple documentation they said:
"On iPad, this method displays the action sheet in a popover whose arrow points to the specified rectangle of the view. The popover does not overlap the specified rectangle."
`
All I see is a list (which looks like a rolodex), how do I make this like the combo box option?
I haven't tried this, so I can't say that it will 100% work, but ths is what I would attempt to do:
Extend UIPickerView and initially give it only enough height for one row
In the new class, intercept touchesBegan: so that if the control is in the 1 row mode it will first expand to the full height (using an animation of course). I would probably NOT pass touches on to the super class in this mode
If the control is already in the full height mode, let the touch pass on through to the super class.
Add some other communication with other components on the screen so that when the user touches them, the extended UIPickerView shrinks back to it's 1 line height form, with more animation.
To make all of that work you probably need all your controls in a scroll view that does proper auto layout so that as you change the frame size of the UIPickerView thingie the other controls move around appropriately.
I agree with Henrik that this is very non-Apple however. It seems the prescribed Apple implementation would involve a tableview cell with a disclosure button that takes you to another screen containing the picker. I know the Apple HUI guidelines don't cover all cases, but it seems they probably cover this one.
I am having some trouble getting my application to properly resize the text of UILabels when the user does a swipe to delete or other type of delete. Currently, the delete button is covering up the text that is in the cell (if it is really long). I would like for them to operate like how SMS (move clipped text down a line) or iPod (delete button resizing text).
I am using a custom UITableViewCell I am working with two labels, UIImageView and a couple of subviews for backgroundView and selectedBackgroundView. I have been playing with the springs and struts of the labels in the cell and partially attained my desired effect however, the text has a weird, quick resizing bug where it becomes deformed and stretched out and then is returned proper size when the delete button is done animating.
As far as other things that I have tried, I have made sure that my text does not adjust-to-fit and I have made my minimum font size the font size that I set for the label. I have also tried over-riding layoutSubviews but that didn't seem to have any effect at all.
If a screenshot (of the deforming label) or code would be helpful, I can post both but since nothing I have done is working, I figured they would be of little value.
fixed it by setting the "mode" of the label in the view panel to "left"
It sounds like you need to set the number of lines property and the wrap property for the labels.
If your actively changing the size of the label itself, you might want to animate that change.
I am using a UITextView and enabling paging (in both IB and programatically toggling it on and off). There's a lot of text and when scrolling with paging enabled sometimes the first and/or last line of the currently viewable text ends up halfway in view and half out of view at the bottom or top of the frame so you can only see the top or bottom half of that line of text. (I hope I'm explaining that correctly)
Does anyone know a way to insure that it pages correctly so it there's no lines of text half cut off??
A few notes
1. The font size is adjustable by the user.
2. I've tried setContentOffset,setContentInset,setContentSize and it's not helping (unless I'm using them wrong)
3. I am using a txt file to populate the UITextView
Thanks in advance!!
UITextView is a subclass of UIScrollView. As such I do not believe UITextView actually supports paging as this is a feature of UIScrollView. Can you please take a step back and explain the end goal, as it sounds like rendering an NSString in to a UIScrollView might be actually what you want, instead of a UITextView.
