I've seen a lot of text fields with triggering a datepicker.
I want have only one method to make a datepicker. This datepicker must have a method selector with the identifier of the text fields. I don't know how can i make this.
Here is my code:
- (IBAction)launchPickerDate:(id)sender{
UIDatePicker *datepickerNew = [UIDatePicker new];
[datepickerNew setHidden:NO];
datepickerNew.frame = CGRectOffset(datepickerNew.frame, 0, 244);
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil
delegate:nil
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
[actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
CGRect pickerFrame = CGRectMake(0, 40, 0, 0);
UIDatePicker *launchPickerDate = [[UIDatePicker alloc] initWithFrame:pickerFrame];
[launchPickerDate addTarget:self action:#selector(SelectDatePicker:) forControlEvents:UIControlEventValueChanged];
[actionSheet addSubview:launchPickerDate];
UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:#"Ok"]];
closeButton.momentary = YES;
closeButton.frame = CGRectMake(260, 7.0f, 50.0f, 30.0f);
closeButton.segmentedControlStyle = UISegmentedControlStyleBar;
closeButton.tintColor = [UIColor blackColor];
[closeButton addTarget:self action:#selector(closeDatePicker:) forControlEvents:UIControlEventValueChanged];
[actionSheet addSubview:closeButton];
[actionSheet showInView:[[UIApplication sharedApplication] keyWindow]];
[actionSheet setBounds:CGRectMake(0, 0, 320, 485)];
}
I didn't really get your question but it seems to me you want to make some changes to your date picker based upon the text field selected. You can recognize the textfield from which the method was called using the tag property. Like
if (sender.tag==1){
//do something as first text field selected
}else if(sender.tag==2){
//do something as second text field selected
}
you can specify the tags for text field either by interface builder(if you are using xib's) or via code like. firstTextField.tag=1;
and so on.. hope this helps... if anything else just let me know

I need to set size UIActionSheet title "Select option to Copy"
with this code :
[[UIActionSheet alloc] initWithTitle:#"Select option to copy:" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil
otherButtonTitles:#"copy all ",nil];
You could take advantage of Runtime Properties to set the font. By using NSAttributedString you can achieve this.
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#"" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil
otherButtonTitles:#"copy all ",nil];
//Creating Attributed String with System Font size of 30.0f
NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:#"Select option to copy:" attributes:#{NSFontAttributeName: [UIFont systemFontOfSize:30.0f]}];
//Accessing the Alert View Controller property from Action Sheet
UIAlertController *alertController = [actionSheet valueForKey:#"_alertController"];
//Setting Attributed Title property of Alert View Controller
[alertController setValue:attrString forKey:#"_attributedTitle"];
//Displaying the Action Sheet
[actionSheet showInView:self.view];
You can change the title font of uiactionsheet by using this delgate
-(void)willPresentActionSheet:(UIActionSheet *)actionSheet {
for (UIView *_currentView in actionSheet.subviews) {
if ([_currentView isKindOfClass:[UILabel class]]) {
UILabel *l = [[UILabel alloc] initWithFrame:_currentView.frame];
l.text = [(UILabel *)_currentView text];
[l setFont:[UIFont fontWithName:#"Arial-BoldMT" size:20]];
l.textColor = [UIColor darkGrayColor];
l.backgroundColor = [UIColor clearColor];
[l sizeToFit];
[l setCenter:CGPointMake(actionSheet.center.x, 25)];
[l setFrame:CGRectIntegral(l.frame)];
[actionSheet addSubview:l];
_currentView.hidden = YES;
break;
}
}
}
I have a class variable that's an instance of UIActionSheet, called actionSheet. I add an instance of UIPickerView as well as an instance of UISegmentedControl. Though when I tap the "Done" button (instance of UISegmentedControl), my class method dismissActionSheet is never called. Can anyone help me out?
//########################################
-(IBAction)chooseTopicButtonPressed{
actionSheet = [[UIActionSheet alloc] initWithTitle:nil
delegate:nil
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
[actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
CGRect pickerFrame = CGRectMake(0, 40, 0, 0);
UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:pickerFrame];
pickerView.showsSelectionIndicator = YES;
pickerView.dataSource = singlePicker.dataSource;
pickerView.delegate = singlePicker.delegate;
[actionSheet addSubview:pickerView];
UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:#"Done"]];
closeButton.momentary = YES;
closeButton.frame = CGRectMake(10, 6, 300, 30);
closeButton.segmentedControlStyle = UISegmentedControlStyleBar;
closeButton.tintColor = [UIColor blueColor];
[closeButton addTarget:self action:#selector(dismissActionSheet:) forControlEvents:UIControlEventTouchUpInside];
//dismissActionSheet NOT BEING CALLED FOR SOME REASON!!!
[actionSheet addSubview:closeButton];
[actionSheet showInView:[[UIApplication sharedApplication] keyWindow]];
[actionSheet setBounds:CGRectMake(0, 0, 320, 485)];
}
-(void)dismissActionSheet{
NSLog(#"dismissActionSheet called");
[actionSheet dismissWithClickedButtonIndex:0 animated:YES];
}
The method dismissActionSheet doesn't have any arguments so the #selector should be as follows:
[closeButton addTarget:self action:#selector(dismissActionSheet) forControlEvents:UIControlEventTouchUpInside];
I was looking for a way to make a UIPickerView show a "Done", "Cancel" buttons.
Googling around I found good posts, all of them had UIActionSheet involved.
So I did that
container is a UIView
actionSheet is a UIActinSheet
pickerView is a UIPickerView
in viewDidLoad:
container = [[[UIView alloc] initWithFrame:CGRectMake(rect.origin.x,rect.origin.y, rect.size.width, rect.size.height)] autorelease];
[self.view addSubview:container];
actionSheet = [[UIActionSheet alloc] initWithTitle:#"myTitle"
delegate:nil
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
[actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
CGRect pickerFrame = CGRectMake(0, 40, 0, 0);
pickerView = [[[UIPickerView alloc] initWithFrame:pickerFrame]autorelease];
pickerView.showsSelectionIndicator = YES;
pickerView.dataSource = self;
pickerView.delegate = self;
UIToolbar *toolbar = [[[UIToolbar alloc] init] autorelease];
toolbar.frame = CGRectMake(0, 0, self.view.frame.size.width, 44);
NSMutableArray *items = [[[NSMutableArray alloc] init] autorelease];
[items addObject:[[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:#selector(dismissActionSheet)] autorelease]];
[items addObject:[[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:#selector(goActionSheet)] autorelease]];
[items addObject:[[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(goActionSheet)] autorelease]];
[toolbar setItems:items animated:NO];
[actionSheet addSubview:toolbar];
[actionSheet addSubview:pickerView];
[actionSheet showInView:container];
[actionSheet setBounds:CGRectMake(0, 0, 320, 485)];
The app starts great, and the whole thing shows up nice as supposed to be on the line: [actionSheet showInView:container];
Now, When I try to dismiss the ActionSheet, it works great!
in dismissActionSheet:
[actionSheet dismissWithClickedButtonIndex:1 animated:NO];
The problem is, how do I make it show up again?
When I use:
[actionSheet showInView:container];
I only get the Toolbar picking from the bottom with the buttons and that's it. The whole PickerView is at the bottom and I can't see it.
What am I doing wrong here?
Action sheets are intended to be used more like alerts, in that they are standalone "make a choice now" presenters. They do normally only display part-way on the iPhone.
Your picker should be independent of the action sheet. If you want to have "Done" and "Cancel" buttons perhaps you would want to consider adding them to the picker's navigation bar?
You can use UIToolBar having Done and Cancel Button, with your PickerView, this will be easy.
I have read on another post (how to dismiss action sheet) that I can use
[actionSheet dismissWithClickedButtonIndex:0 animated:YES];
to dismiss the uiactionsheet with the close button, as defined in:
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil
delegate:nil
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
[actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
CGRect pickerFrame = CGRectMake(0, 40, 0, 0);
UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:pickerFrame];
pickerView.showsSelectionIndicator = YES;
pickerView.dataSource = self;
pickerView.delegate = self;
[actionSheet addSubview:pickerView];
[pickerView release];
UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:#"Close"]];
closeButton.momentary = YES;
closeButton.frame = CGRectMake(260, 7.0f, 50.0f, 30.0f);
closeButton.segmentedControlStyle = UISegmentedControlStyleBar;
closeButton.tintColor = [UIColor blackColor];
[closeButton addTarget:self action:#selector(dismissActionSheet:) forControlEvents:UIControlEventValueChanged];
[actionSheet addSubview:closeButton];
[actionSheet dismissWithClickedButtonIndex:0 animated:YES];
[closeButton release];
[actionSheet showInView:[[UIApplication sharedApplication] keyWindow]];
[actionSheet setBounds:CGRectMake(0, 0, 320, 485)];
However, I am not sure where to place this line, assuming this will solve my problem:
[actionSheet dismissWithClickedButtonIndex:0 animated:YES];
Also, the app crashes when I click the close button, with error message "PROGRAM RECEIVED ERROR MESSAGE SIGBRT". I assume my two problems are related. Any help out there?
Just implement dismissActionSheet and put your dismiss message there.
The dismissActionSheet method would look something like this:
-(void)dismissActionSheet {
[sheet dismissWithClickedButtonIndex:0 animated:YES];
}
I'm trying to get a UIDatePicker with a UIButton to show up in a UIActionSheet. Unfortunately it gets cropped off and the entire Date Picker is not visible. I have not even attempted to add the UIButton yet. Can anyone suggest on getting the entire view to fit properly? I'm not sure how to add the proper dimensions as UIActionSheet seems to lack an -initWithFrame: type constructor.
UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:#"Date Picker"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:nil];
// Add the picker
UIDatePicker *pickerView = [[UIDatePicker alloc] init];
pickerView.datePickerMode = UIDatePickerModeDate;
[menu addSubview:pickerView];
[menu showInView:self.view];
[pickerView release];
[menu release];
I've also tried with something similar to:
UIActionSheet *menu = [[UIActionSheet alloc] initWithFrame:CGRectMake(200.0, 200.0, 100.0f, 100.0f)];
The coords are ofcourse not realistic, but they don't seem to affect the position/size of the UIActionSheet.
You can use something like this (adjust the coordinates):
UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:#"Date Picker"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:nil];
// Add the picker
UIDatePicker *pickerView = [[UIDatePicker alloc] init];
pickerView.datePickerMode = UIDatePickerModeDate;
[menu addSubview:pickerView];
[menu showInView:self.view];
[menu setBounds:CGRectMake(0,0,320, 500)];
CGRect pickerRect = pickerView.bounds;
pickerRect.origin.y = -100;
pickerView.bounds = pickerRect;
[pickerView release];
[menu release];
But you better create a fullscreen view with a UIDatePicker and a navigation bar. For an example see UICatalog -> Pickers sample from the iPhone DevCenter.
Try adding following line to resolve disabled buttons issue
[menu sendSubviewToBack:pickerView];
Dmitry's answer is almost correct. However, the frame of the actionsheet is too small, and therefore touches near the bottom of the picker are ignored. I have corrected these problems:
UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:#"Date Picker"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:#"OK",nil];
// Add the picker
UIDatePicker *pickerView = [[UIDatePicker alloc] init];
pickerView.datePickerMode = UIDatePickerModeTime;
[menu addSubview:pickerView];
[menu showInView:_mainView];
CGRect menuRect = menu.frame;
CGFloat orgHeight = menuRect.size.height;
menuRect.origin.y -= 214; //height of picker
menuRect.size.height = orgHeight+214;
menu.frame = menuRect;
CGRect pickerRect = pickerView.frame;
pickerRect.origin.y = orgHeight;
pickerView.frame = pickerRect;
[pickerView release];
[menu release];
This works for me
NSString *title = UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation) ? #"\n\n\n\n\n\n\n\n\n" : #"\n\n\n\n\n\n\n\n\n\n\n\n" ;
UIActionSheet *actionSheet = [[UIActionSheet alloc]
initWithTitle:[NSString stringWithFormat:#"%#%#", title, NSLocalizedString(#"SelectADateKey", #"")]
delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:#"Ok", nil];
[actionSheet showInView:self.view];
UIDatePicker *datePicker = [[[UIDatePicker alloc] init] autorelease];
datePicker.datePickerMode = UIDatePickerModeDate;
[actionSheet addSubview:datePicker];
a little tricky but it works!
Buttons at top, picker at bottom:
UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:#"Date Picker"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:#"OK",nil];
// Add the picker
UIDatePicker *pickerView = [[UIDatePicker alloc] init];
pickerView.datePickerMode = UIDatePickerModeTime;
[menu addSubview:pickerView];
[menu showInView:_mainView];
CGRect menuRect = menu.frame;
menuRect.origin.y -= 214;
menuRect.size.height = 300;
menu.frame = menuRect;
CGRect pickerRect = pickerView.frame;
pickerRect.origin.y = 174;
pickerView.frame = pickerRect;
[pickerView release];
[menu release];
Make sure you show the UIActionSheet in the right view when inside a UITabBarController to avoid interactivity problems at the bottom:
[actionSheet showInView:self.parentViewController.tabBarController.view];
Possibly not directly answering the specific question (how to get the UIDatePicker to fit), but for an implementation of UIActionSheet which presents a UIDatePicker (also others) please see ActionSheetPicker. From it's Readme:
Easily present an ActionSheet with a PickerView, allowing user to select from a number of immutable options. Based on the HTML drop-down alternative found in mobilesafari.
Also:
Some code derived from marcio's post on Stack Overflow
[ Add UIPickerView & a Button in Action sheet - How? ]
Even if one doesn't use the code, it's good reading before you roll your own.
Update:
This version is deprecated: use ActionSheetPicker-3.0 instead.
