I know that there has been one question about this but it is not clear to me. I want to add a UISlider to UIAlertView. In the UIAlertView, I also add one UILabel to show the value of UISlider. What I have been done so far is:
UIAlertView *alert= [[UIAlertView alloc]
initWithTitle: #"Set delay"
message: #" "
delegate: nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
UISlider *mySlider=[[UISlider alloc] initWithFrame:CGRectMake(20, 50, 200, 20)];
mySlider.maximumValue=10.00;
mySlider.minimumValue=1.00;
UILabel *myLabel=[[UILabel alloc] initWithFrame:CGRectMake(220, 50, 50, 40)];
int x=.........;//x should get value of mySlider
[myLabel setText:[NSString stringWithFormat:#"%d",x]];
[alert addSubview:myLabel];
[alert addSubview:mySlider];
[alert show];
[alert release];
so I want variable x to get value of mySlider and the myLabel will show the value of x. I get stuck at this point. Any suggestion is really appreciated.
Here what you need to do:
Make the UILabel global, that mean declare it on the header file (this is to reach the label easily).
Then add a target to the slider, with ValueChanged event.
[mySlider addTarget:self action:#selector(sliderHandler:) forControlEvents:UIControlEventValueChanged];
next, implement the sliderHandler method:
- (void) sliderHandler: (UISlider *)sender {
int x = sender.value;
[myLabel setText:[NSString stringWithFormat:#"value = %d",x]];
}
That will work with you.

I want to add a UISlider on a UIAlerView but I am not able to do that. I also google that but I found only two answers and both of them are not showing any any result here is code what I found and applied in my project:
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"title" message:#"msg" delegate:self cancelButtonTitle:#"cancel" otherButtonTitles:#"ok", nil];
alertView.title = #"title";
CGRect frame = CGRectMake(alertView.frame.origin.x+10,alertView.frame.origin.y+20,100, 100.0);
UISlider *slider = [[UISlider alloc] initWithFrame:frame];
[slider addTarget:self action:#selector(sliderAction:) forControlEvents:UIControlEventValueChanged];
[slider setBackgroundColor:[UIColor clearColor]];
slider.minimumValue = 0.0;
slider.maximumValue = 10.0;
slider.continuous = YES;
slider.value = 25.0;
[alertView addSubview:slider];
[alertView show];
I think the frame of slider is not proper thats why its not being displayed.
can anyone help me in that.....
Thank you in advance...
You are adding the Slider in Alert view not in parent view of Alert view.
So your frame value will add the slider some where wide in alert view, result will be hidden on alert view.
so replace this line
CGRect frame = CGRectMake(alertView.frame.origin.x+10,alertView.frame.origin.y+20,100, 100.0);
To
CGRect frame = CGRectMake(10,20,100, 100.0);
The UIAlertView is also a UIView. I indeed, you could add the subview in it. But Apple says
"The UIAlertView class is intended to be used as-is and does not support subclassing. The view hierarchy for this class is private and must not be modified."
So Better to have custom view which will act as alertview.Like this one
i have a problem like this:
i want to show a customized view inside a alert view. so i create a separate xib file and designed my interface.and implemented the class for it too.but when i apply below code,it gives me an error.
this is the code :
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Confirm your Action"
message:#"Click OK to confirm"
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:#"Cancel",nil];
NSArray *subviewArray = [[NSBundle mainBundle] loadNibNamed:#"customDialogViewController" owner:self options:nil];
customDialogViewController *myView = (customDialogViewController*) [subviewArray objectAtIndex:0];
[alert setValue:myView forKey:#"accessoryView"];
//alert.alertViewStyle = UIAlertViewStylePlainTextInput;
alert.tag = KAlertViewthree;
[alert show];
and this is my error :
Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'child view controller:<ScheduleView: 0x8adf1a0> should have parent view controller:<_UIModalItemAccessoryViewControllerForLegacyAlert: 0xa888b70> but actual parent is:<UINavigationController: 0x8add8c0>'
i really new to iOS development.did i do this wrong ? where is the mistake ? i don't know what is this Nib file talking here "loadNibNamed:#bla boa " i just gave my xib name for that. can anyone give me a better way to do this or can you tell me the where i have to change to fix this issue ?
please guide me some one..
thank you.
This API has solution for your problem use this and have fun
https://github.com/Darktt/DTAlertView
https://github.com/Scott90/SDCAlertView
https://github.com/lmcd/LMAlertView
for all who having this problem,
i have followed this link..and for the star marks, i used this..
all you have to do is add below files to the project
CustomIOS7AlertView.h
CustomIOS7AlertView.m
JSFavStarControl.h
JSFavStarControl.m
and put below code where you want to pop up the alert view
// Here we need to pass a full frame
CustomIOS7AlertView *alertView = [[CustomIOS7AlertView alloc] init];
// Add some custom content to the alert view
[alertView setContainerView:[self createDemoView]];
// Modify the parameters
[alertView setButtonTitles:[NSMutableArray arrayWithObjects:#"Close1", #"Close2", #"Close3", nil]];
[alertView setDelegate:self];
// You may use a Block, rather than a delegate.
[alertView setOnButtonTouchUpInside:^(CustomIOS7AlertView *alertView, int buttonIndex) {
NSLog(#"Block: Button at position %d is clicked on alertView %d.", buttonIndex, [alertView tag]);
[alertView close];
}];
[alertView setUseMotionEffects:true];
// And launch the dialog
[alertView show];
and inside the method of createDemoView,you have to implement your customised view.in my case it is like this
UIView *demoView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 290, 100)];
//alertView.tag=2;
UILabel *rateLbl=[[UILabel alloc]initWithFrame:CGRectMake(10, 10, 290, 45)];
rateLbl.backgroundColor=[UIColor clearColor];
rateLbl.font=[UIFont boldSystemFontOfSize:15];
rateLbl.text=#"Rate";
UILabel *cmntLable=[[UILabel alloc]initWithFrame:CGRectMake(10, 45, 290, 45)];
cmntLable.backgroundColor=[UIColor clearColor];
cmntLable.font=[UIFont boldSystemFontOfSize:15];
cmntLable.text=#"Add Comment";
UIImage *dot, *star;
dot = [UIImage imageNamed:#"dot.png"];
star = [UIImage imageNamed:#"star.png"];
JSFavStarControl *rating = [[JSFavStarControl alloc] initWithLocation:CGPointMake(150, 20) dotImage:dot starImage:star];
[rating addTarget:self action:#selector(updateRating:) forControlEvents:UIControlEventValueChanged];
UILabel *lblAlertTItle=[[UILabel alloc]initWithFrame:CGRectMake(5, 5, 290, 45)];
lblAlertTItle.backgroundColor=[UIColor clearColor];
lblAlertTItle.textAlignment=UITextAlignmentCenter;
lblAlertTItle.font=[UIFont boldSystemFontOfSize:18];
lblAlertTItle.text=#"Choose your sharing option";
UITextField *text = [[UITextField alloc]initWithFrame:CGRectMake(150, 57, 100, 25)];
text.backgroundColor=[UIColor whiteColor];
//[demoView addSubview:lblAlertTItle];
[demoView addSubview:text];
[demoView addSubview:rating];
[demoView addSubview:rateLbl];
[demoView addSubview:cmntLable];
return demoView;
so my output is like this.
use it and have fun :)
thank you for everyone who helped me.
In to native Alert-view in ios7 that not possible to adding custom View as a sub-view of alert-view. You can use ios-custom-alertview for doing this kind of task you can do what you want. Hope this helpful to you.
I am using this ios-custom-alertview with Adding two Bellow file in to my project.
CustomIOS7AlertView.h
CustomIOS7AlertView.m
and how to use there is quick-start-guide
I am creating an Alert view on click of a button. I have placed a UITextfield in it. But the Alertview is shifted upwards in the screen. I am not able to bring it back at the center of the screen.
Here is my code and Screenshot.
and the code for creating this Alert view is this:-
- (IBAction)btn_cancelAppointment_click:(id)sender
{
// Here We are Creating Alertview which asks for
UIAlertView* cancelAlert = [[UIAlertView alloc] init];
[cancelAlert setDelegate:self];
[cancelAlert setTitle:#"Are you sure you want to request cancellation of this appointment?"];
[cancelAlert setMessage:#" "];
[cancelAlert addButtonWithTitle:#"NO"];
[cancelAlert addButtonWithTitle:#"YES"];
UITextField * txt_cancelNote = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 88.0, 245.0, 30.0)];
[txt_cancelNote setBackgroundColor:[UIColor whiteColor]];
[txt_cancelNote setBorderStyle:UITextBorderStyleRoundedRect];
[txt_cancelNote setPlaceholder:#"Enter cancellation note"];
txt_cancelNote.tag = 11;
[cancelAlert addSubview:txt_cancelNote];
cancelAlert.delegate = self;
[cancelAlert show];
}
So, if somebody can tell me how to bring it back to the center of the screen. Any help will be highly appreciated.
Give a try by setting the transform property of the UIAlertView
UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:#"Test" message:nil delegate:self cancelButtonTitle:#"OK" otherButtonTitles: nil];
alertView.transform = CGAffineTransformMakeTranslation(x, y);
I use the following code to show a UIAlertView with a text field:
UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:title message:nil delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Rename", nil];
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
UITextField* textField = [alertView textFieldAtIndex:0];
textField.clearButtonMode = UITextFieldViewModeWhileEditing;
[alertView show];
The result looks like this on iOS 5.1:
and on iOS 6.1:
As you can see, the clear button is a bit higher than it should be on iOS 6.1. Any idea how to properly center the button? Adding textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter; does not help either.
(Apparently, this is a bug in iOS 6.1 but maybe someone knows a workaround. Besides, the height of the text field in alert views also seem to differ in different OS versions but that is another issue.)
This looks like a bug from Apple, but you can always add your own clear button in the textField, doing something like this :
First create a UITextField property:
#property (nonatomic, strong) UITextField *textField;
And then assign it to the alertView's textField
UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:title message:nil delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Rename", nil];
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
self.textField = [alertView textFieldAtIndex:0];
self.textField.delegate = self;
//Create a custom clear button
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 19, 19)];
[button setImage:[UIImage imageNamed:#"clearButton.png"] forState:UIControlStateNormal];
[button addTarget:self action:#selector(clearText) forControlEvents:UIControlEventAllTouchEvents];
[self.textField setRightView:button];
self.textField.rightViewMode = UITextFieldViewModeAlways;
And then in the clearText method,
- (void)clearText {
[self.textField setText:#""];
}
I tried this out and it works
Hope this helps
Another way to do this is by overriding UITextField's clearButtonRectForBounds:.
In my UIViewController <GLKViewDelegate> in need to make a simple text input when selecting a object.
Is there in UIKit a simple multiline text input popup ready to use ?
I already found UIAlertView with alertViewStyle=UIAlertViewStylePlainTextInput but it's only a simple line input.
thx
If you mean is there an equivalent of the text input UIAlertView with a UITextView rather than a UITextField, the answer is no.
Your question is not very clear. but I think UIActionSheet is what you need.
Edit
You can try this out
Set this in un .h file the the delegate like this
#interface NameOfYourClass : UIViewController <UIActionSheetDelegate>
And add this code in un .m File
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#"Action Sheet" delegate:self cancelButtonTitle:#"Cancel Button" destructiveButtonTitle:#"Destructive Button" otherButtonTitles:#"Other Button 1", #"Other Button 2", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleBlackOpaque;
[actionSheet showInView:self.view];
Edit2
So here's what to do to add a textfield to your allertview
UIAlertView *newAlert =[[UIAlertView alloc] initWithTitle:#"ADD item" message:#"Put it blank textfield will cover this" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"OK", nil];
UITextField *newTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)];
newTextField.text=#"";
[newTextField setBackgroundColor:[UIColor whiteColor]];
[newTextField setKeyboardAppearance:UIKeyboardAppearanceAlert];
[newTextField setAutocorrectionType:UITextAutocorrectionTypeNo];
[newTextField setTextAlignment:UITextAlignmentCenter];
[newAlert addSubview:newTextField];
[newAlert show];
