UIPicker / UIActionSheet works fine on iPhone but only thin line on iPad
The following Code works fine on iPhone, but not on iPad. Only get a thin line instead of the full view. Have been researching and maybe something with the rect for the picker? All size numbers seem to be reasonable.
actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:nil
cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];
[actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
CGRect pickerFrame = CGRectMake(0, 40, 0, 0);
if ( isipad ) pickerFrame = CGRectMake(0, 345, 400, 216);
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:@"Select"]];开发者_运维问答
closeButton.momentary = YES;
closeButton.frame = CGRectMake(10, 7.0f, 100.0f, 30.0f);
closeButton.segmentedControlStyle = UISegmentedControlStyleBar;
closeButton.tintColor = [UIColor blackColor];
[closeButton addTarget:self action:@selector(dismissActionSheet:) forControlEvents:UIControlEventValueChanged];
[actionSheet addSubview:closeButton];
[closeButton release];
UISegmentedControl *skipButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:@"Skip Birth Year"]];
skipButton.momentary = YES;
skipButton.frame = CGRectMake(200, 7.0f, 100.0f, 30.0f);
skipButton.segmentedControlStyle = UISegmentedControlStyleBar;
skipButton.tintColor = [UIColor blackColor];
[skipButton addTarget:self action:@selector(skipActionSheet:) forControlEvents:UIControlEventValueChanged];
[actionSheet addSubview:skipButton];
[skipButton release];
[actionSheet setBounds:CGRectMake(0, 0, self.view.frame.size.width, 216)];
[actionSheet showInView:self.view];
[actionSheet setBounds:CGRectMake(0, 0, self.view.frame.size.width, 216)];
Well, got it to work by putting most of the code in
- (void)willPresentActionSheet:(UIActionSheet *)actionSheet
including
pickerFrame = CGRectMake(0, 0, 320, 214);
AND
initWithTitle:@"\n\n\n\n\n\n\n\n\n\n\n\n\n\n"
for the action sheet. Magic I guess.
Is this correct:
CGRect pickerFrame = CGRectMake(0, 40, 0, 0); //This line sets the frame height and width equal to 0.
if ( isipad ) pickerFrame = CGRectMake(0, 345, 400, 216);
Is your isipad
bool working ok?
Thanks for your post ort11. I needed to make an iPad app and I did working copy-paste code from iPhone app and on iPad is the same: a small line :)
My needs is a language chooser only, nothing else.
Here are the codes based on your answer:
- (IBAction)btLanguageChooserPressed {
NSLog(@"btLanguageChooserPressed");
[self createLanguageSheet];
// show the sheet: will be invoked the willPresentActionSheet method
[sheet showInView:self.view];
}
- (void)createLanguageSheet {
NSLog(@"createLanguageSheet()");
// hoolly crap, need to initialize the title with: @"\n\n\n\n\n\n\n\n\n\n\n\n\n\n" to get working!!!
sheet = [[UIActionSheet alloc] initWithTitle:@"\n\n\n\n\n\n\n\n\n\n\n\n\n\n"
delegate:self
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
[sheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
}
- (void)willPresentActionSheet:(UIActionSheet *)actionSheet
{
CGRect pickerFrame = CGRectMake(0, 0, 320, 216);
pickerView = [[UIPickerView alloc] initWithFrame:pickerFrame];
pickerView.showsSelectionIndicator = YES;
pickerView.dataSource = self;
pickerView.delegate = self;
[sheet addSubview:pickerView];
// add close button:
UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:@"OK"]];
closeButton.momentary = YES;
closeButton.frame = CGRectMake(120, 12, 100, 30);
closeButton.segmentedControlStyle = UISegmentedControlStyleBar;
closeButton.tintColor = [UIColor blackColor];
[closeButton addTarget:self action:@selector(dismissSheet:) forControlEvents:UIControlEventValueChanged];
[sheet addSubview:closeButton];
[sheet setBounds:CGRectMake(0, 0, self.view.frame.size.width, 216)];
//[sheet showInView:self.view];//already called, why need again?
//[sheet setBounds:CGRectMake(0, 0, self.view.frame.size.width, 216)];
}
at runtime I do a cache in a variable:
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
NSLog(@"Selected: %@", [arrayLanguages objectAtIndex:row]) ;
selectedRow = row;
}
and here is the finish:
- (void)dismissSheet:(id)sender {
[sheet dismissWithClickedButtonIndex:0 animated:YES];
NSString* selectedLanguage = [arrayLanguages objectAtIndex:selectedRow];
NSLog(@"dismissSheet() selectedLanguage: %@",selectedLanguage);
switch (selectedRow) {
case 0://English
imgCurrentLanguage.image = [UIImage imageNamed:@"english.png"];
break;
case 1:// Deutsch
break;
case 2://Français
break;
case 3://Italiano
break;
case 4://Español
break;
default:
break;
}
// TODO: do the changes in GUI
}
I am not able to move this actionsheet from the center of the screen to botton- left corner. But I am trying...
I think this would be the cleanest solution :
@interface MyActionSheet : UIActionSheet
@property (nonatomic, strong) IBOutlet UIView * customView;
@end
@implementation MyActionSheet
-(CGRect)bounds {
return self.customView.bounds;
}
@end
then:
MyActionSheet * s = [[MyActionSheet alloc] initWithTitle:nil delegate:nil cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];
s.customView = _auxView;
[s addSubview:_auxView];
