On the iPhone, in the Calendar App when you press the "Delete Event" button a confirmation slides in from the bottom. Does anyone know of any example code for this, or is it just a short view presented modally with a custom background?
If this is made using a custom view, do you know where I can get a background graphic the same as the one used in the Calendar App?
Thanks in advance!
NB: I am not talking about a UIAlertView dialog box, but the slide-in confirmation with multiple buttons.
UIActionSheet is what you are looking for.
Here is some code example to get you started with:
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#"Save photo?" delegate:self cancelButtonTitle:#"No" destructiveButtonTitle:#"Yes" otherButtonTitles:nil];
[actionSheet showInView:self.view];
[actionSheet release];
This will slide in an action sheet from the bottom. It has 2 buttons. Yes and No.
When a user selects any button the actionSheet:didDismissWithButtonIndex: method gets called
-(void) actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex{
//your code here
}
Your controller class will have to subscribe to the < UIActionSheetDelegate > protocol
Hope this helps!
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#"title" delegate:self cancelButtonTitle:#"cancel" destructiveButtonTitle:#"destructive" otherButtonTitles:#"other", nil];
[actionSheet showInView:self.view];
[actionSheet release];

I'm new to iOS and working on Google Map SDK and able to show the map on the view but now
I want to add a UITextField and enter the location over there
On buttons click that location should be shown in the map
So please kindly help me out.
I would suggest you to add buttons on the UINavigationBar or by placing a UIToolBar on the top of the map view and then by clicking on it show a UIAlertView with textfield that takes in the input and after the alert's ok is pressed take the location entered and do your stuff. Don't add buttons on the map,it would bring down the usability factor.
If you have a navigation bar already, try this
UIBarButtonItem *locationButton = [[UIBarButtonItem alloc] initWithTitle:#"location" style:UIBarButtonItemStyleBordered target:self action:#selector(showAlertWithTextField)];
self.navigationItem.rightBarButtonItem=locationButton;
-(void)showAlertWithTextField{
UIAlertView* dialog = [[UIAlertView alloc] initWithTitle:#"Enter Location" message:#"" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Add", nil];
[dialog setAlertViewStyle:UIAlertViewStylePlainTextInput];
[dialog show];
}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if (buttonIndex == 1)
NSLog(#"%#",[[alertView textFieldAtIndex:0]text]);
}
UIActionSheet, how to dismiss it with a single click?
I have to click a button 2 times so it gets dismissed, what should I do to make it dismissble after the first click?! Here is my code:
-(void)buttonHeld:(id)sender
{
UIActionSheet *popupQuery = [[UIActionSheet alloc] initWithTitle:#"Delete Contact?!" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:#"Delete" otherButtonTitles: nil];
popupQuery.actionSheetStyle = UIActionSheetStyleBlackOpaque;
[popupQuery showInView:self.view];
[popupQuery release];
}
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0) {
NSLog(#"Delete button clicked Button Clicked");
else if (buttonIndex == 1) {
NSLog(#"Cancel Button Clicked");
}
}
Based on the name of your method "buttonHeld", my assumption is that you are trying to launch the UIActionSheet from a UILongPressGestureRecognizer. You will need to use the code listed below if you want it to work as expected. The problem stems from UILongPressGestureRecognizer being a 'continuous gesture' which fires multiple times and progresses through several different states. You'll need to monitor for the correct state and then load your UIActionSheet. I had the exact same problem and this is what solved it for me.
- (IBAction) buttonHeld:(UILongPressGestureRecognizer *)sender {
if (sender.state == UIGestureRecognizerStateBegan) {
UIActionSheet *popupQuery = [[UIActionSheet alloc]
initWithTitle:#"Delete Contact?!"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:#"Delete"
otherButtonTitles:nil];
popupQuery.actionSheetStyle = UIActionSheetStyleBlackOpaque;
[popupQuery showInView:self.view];
}
}
This is how i dismiss the actionsheet...
[actionSheet dismissWithClickedButtonIndex:0 animated:YES];
Hope this helps
It took me a few taps to get it to cancel as well. The problem ended up being which view I attached it to.
[action showInView:self.view];
self.view was only referenced in IB. I changed it to a different view and it worked.
No need to declare in this delegate when you alloc the actionsheet you have make cancel Button that by default dismiss the ActionSheet some thing like this
[[UIActionSheet alloc] initWithTitle:#"" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil otherButtonTitles:btnTitle,#"Send for a date range",nil];
from any other event you can use this method
- (void)dismissWithClickedButtonIndex:(NSInteger)buttonIndex animated:(BOOL)animated
In your code there is a syntax error you are putting else block in if block.
If u're developing for the iphone it's always safe to use :
[popupQuery showFromBarButtonItem:sender animated:YES]
or showFromTabBar: or showFromToolBar etc. instead of showinView.
I'd like to create a popup menu, from my tab bar.
I've seen them, but I'm not sure what they called ?
Kind of like a speak bubble.
I think copy / paste is the sort of thing I mean.
You are searching for the UIMenuController.
This question might help you.
That could be the UIActionSheet. You might want to give it a try.
//Your delegate for pressed buttons.
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
//Your Action for pressed button.
[actionSheet release];
}
//Declare a method to show your sheet
-(void)showActionSheet
{
UIActionSheet *menu = [[UIActionSheet alloc]
initWithTitle: #"Action Sheet Title"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:#"Delete"
otherButtonTitles:#"Other Button1", #"Other Button2", nil];
[menu showInView:self.view];
}
But you said "bubble", so that could also be the UIAlertView.
Try this:
-(void)showAlertView
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Alert!"
message:#"This is the message that pops up in the bubble."
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
[alert release];
}
On the iPad, you'd want UIPopoverController, but I think that on the iPhone the same sort of interactions are meant to be performed by a separate, full screen controller or by a UIActionSheet. There's no speech bubble on the iPhone such that I'm aware.
I am implementing an action sheet. When I press "ok" button, do these, press "cancel" go back. The "ok" button is working fine, but when I press the "cancel" button, nothing happens, it doesn't retract or do anything, just hang at the actionsheet view.
Below is my code:
To create button on the nav bar:
UIBarButtonItem *clearButton = [[[UIBarButtonItem alloc] initWithTitle:#"Clear History"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(ClearHistoryAction:)] autorelease];
self.navigationItem.leftBarButtonItem = clearButton;
When I click and launch action sheet:
- (IBAction)ClearHistoryAction:(id)sender
{
UIActionSheet *actionSheet = [[UIActionSheet alloc]
initWithTitle:#"Clear History?"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:#"OK"
otherButtonTitles:nil];
// use the same style as the nav bar
actionSheet.actionSheetStyle = self.navigationController.navigationBar.barStyle;
[actionSheet showInView:self.view];
[actionSheet release];
}
if select ok do this:
- (void)actionSheet:(UIActionSheet *)actionSheet
didDismissWithButtonIndex:(NSInteger) buttonIndex
{
if (!buttonIndex == [actionSheet cancelButtonIndex])
{
//do what i want here!
}
}
In the header file, UIActionSheetDelegate is included in #interface.
Late but, a possible Explanation could be :
Seems to be an issue with the tabbar. If you call UIActionSheet's
[sheet showInView:self.view]
from a view controller that is a child of a UITabViewController, then
the hit testing on the cancel button fails in that portion of the
UIActionSheet that lies above the tabbar's view.
If you instead pass in the UITabBarController's view, then the UIActionSheet acts as expected.
[sheet showInView:self.parentViewController.tabBarController.view];
A more detailed explanation here:
UIActionSheet cancel button strange behaviour
I don't know if it'll solve this problem but you'll want to do buttonIndex != [actionSheet cancelButtonIndex] (check not-equal) instead of !buttonIndex == [actionSheet cancelButtonIndex] (invert buttonIndex (!) and check if that's equal).
You need to use showFromBarButtonItem instead of showInView. The problem is that the cancel button is being covered by another view--maybe a toolbar or tabbar--so it's not getting the touch events you think it should get. There are also showFromTabBar and showFromToolbar that should sometimes be used (see the UIActionSheet class reference).
You know how if you click and hold on a link in Safari (for iPhone obviously) it gives you a list of options like "open in new window", "Open". "Copy" etc?
How do you call this and is it possible to get a UIBarButtonItem to do this (but every time it is clicked not just when held down)?
This is how you show this menu:
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil
delegate:self
cancelButtonTitle:#"Cancel",
destructiveButtonTitle:nil
otherButtonTitles:#"Button 1", #"Button 2", #"Button 3", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleDefault;
[actionSheet showInView:[self view]];
[actionSheet release];
In order to connect it to UIBarButtonItem just point the bar button item to a selector that will include the code above.
Don't forget to implement - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex method of UIActionSheetDelegate.
