I am wanting to add a "rate this app" pop up to my app, and am currently looking at doing this through a UIAlertView.
I have the Alert showing fine, with title and cancel/done buttons.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Rate this App"
message:#"My message" delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"OK", nil];
[alert show];
What I need to do now is to replace the "my message" section with 5 custom buttons (stars).
How can I add a row of custom buttons to the middle part of the uialertview?!
You have two options
Use [alertView addSubview:[[UIButton alloc] init:...]]
Inherit a new view from UIAlertView and do it internally
If it is only shown in one spot, 1 is a quick and easy solution. You can setTag for each button and add the same click event
// Interface.h
NSArray *allButtons;
// Implementation.m
UIAlertView *alert = [[UIAlertView alloc] init:...];
UIButton *one = [UIButton buttonWithType:UIButtonTypeCustom];
UIButton *two = [UIButton buttonWithType:UIButtonTypeCustom];
...
// Load "empty star" and "filled star" images
UIImage *starUnselected = ...;
UIImage *starSelected = ...;
[one setImage:starUnselected forControlState:UIControlStateNormal];
[one setImage:starSelected forControlState:UIControlStateSelected];
// repeat for all buttons
...
[one setTag:1];
[two setTag:2];
...
[one addTarget:self action:#selector(buttonPressed:)
forControlEvents:UIControlEventTouchUpInside];
// repeat for all buttons
allButtons = [NSArray arrayWithObjects:one, two, three, four, five];
// all buttons should subscribe
- (void)buttonPressed:(UIButton)sender
{
int tag = [sender getTag]; // The rating value
for (int i = 0; i < [allButtons length]; i++)
{
BOOL isSelected = i < tag;
[(UIButton)[allButtons objectAtIndex:i] setSelected:isSelected];
}
// Set alertTag to store current set one
// read [alert getTag] when OK button is pressed
[alert setTag:tag];
}

I am trying to create a UIAlertView with three buttons (which will be stacked). I would like the Cancel button to be in the middle, between the two other buttons. I have tried setting the cancelButtonIndex to 1, but if there are two other buttons, it simply places them at indexes 0 and 1. I know I could just change the names of the buttons, but I want the darker blue formatting of the cancel button.
EDIT: **
Please note - I know how to get the three buttons with the titles in the correct order, but only if all three buttons essentially look like 'other' buttons; I want the cancel button to have the cancel button dark blue background so that it will look like a regular cancel button.
**
I've tried
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:button1Title,button2Title,nil] autorelease];
alert.cancelButtonIndex = 1;
[alert show];
and
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:nil] autorelease];
alert.cancelButtonIndex = 1;
[alert addButtonWithTitle:button1Title];
[alert addButtonWithTitle:button2Title];
[alert show];
and
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:addButtonWithTitle:button1Title,nil] autorelease];
alert.cancelButtonIndex = 1;
[alert addButtonWithTitle:button2Title];
[alert show];
to no avail. Is it even possible to accomplish what I am trying to do?
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:nil otherButtonTitles:nil] autorelease];
[alert addButtonWithTitle:button1Title];
[alert addButtonWithTitle:#"Cancel"];
[alert addButtonWithTitle:button2Title];
[alert show];
Might Help,
Cheers.
I have two ancillary points to this answer.
1) While, to the best of my knowledge, Apple has not rejected an app for reasonable modification of a UIAlertView; They have said that the view hierarchy of classes like UIAlertView should be considered private.
2) This question is a good example of why you should ask a question more about your end goal rather than the steps to get there. The only reason I know what this question is about is as a result of a comment left at my answer here.
Answer:
Because of your comment I know that you are looking to create a UIAlertView that has stacked buttons even when there are only 2 buttons.
I find the most logical place for code like this is in a category. Since generally the code needed to manipulate the alert-view needs to be around the show call, I created a category method I call instead of show and the method in turn calls show itself.
-(void)showWithButtonsStacked{
static NSString *tempButtonTitle = #"SomeUnlikelyToBeUsedTitle";
BOOL willAddFakeButton = (self.numberOfButtons == 2); // Button are only side by side when there's 2
if (willAddFakeButton){
self.clipsToBounds = YES;
[self addButtonWithTitle:tempButtonTitle]; // add temp button so the alertview will stack
}
BOOL hasCancelButton = (self.cancelButtonIndex != -1); // If there is a cancel button we don't want to cut it off
[self show];
if (willAddFakeButton){
UIButton *cancelButton = nil;
UIButton *tempButton = nil;
for (UIButton *button in self.subviews) {
if ([button isKindOfClass:[UIButton class]]){
if (hasCancelButton && [button.titleLabel.text isEqualToString:[self buttonTitleAtIndex:self.cancelButtonIndex]]){
cancelButton = button;
} else if ([button.titleLabel.text isEqualToString:tempButtonTitle]) {
tempButton = button;
}
}
}
if (hasCancelButton){ // move in cancel button
cancelButton.frame = tempButton.frame;
}
[tempButton removeFromSuperview];
// Find lowest button still visable.
CGRect lowestButtonFrame = CGRectZero;
for (UIButton *button in self.subviews) {
if ([button isKindOfClass:[UIButton class]]){
if (button.frame.origin.y > lowestButtonFrame.origin.y){
lowestButtonFrame = button.frame;
}
}
}
// determine new height of the alert view based on the lowest button frame
CGFloat newHeight = CGRectGetMaxY(lowestButtonFrame) + (lowestButtonFrame.origin.x * 1.5);
self.bounds = CGRectMake(0, 0, self.bounds.size.width, newHeight);
}
}
The way this method accomplishes it's goal is to add a temporary button to the alert-view to force the alert-view to stack the buttons, then it removes the temporary button and adjusts the height. Since it's a category method you use it simply by calling:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Test title" message:#"message" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"OK", nil];
[alert showWithButtonsStacked];
This code results in an alert like this:
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:nil otherButtonTitles:nil] autorelease];
[alert addButtonWithTitle:button1Title];
[alert addButtonWithTitle:#"Cancel"];
[alert addButtonWithTitle:button2Title];
[alert setCancelButtonIndex:1]; // to make it look like cancel button
[alert show];
Set the cancel button to nil and just add it in the other buttons instead
I've added a UIAlertView in my application that grabs user input but I'm unsure as to how I can add a third button. Ideally the three buttons would be across the alert horizontally or two would be above the "cancel" button. The code snippet below is what I'm using to add the UIAlertView.
- (IBAction)initiateSave{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Archive"
message:#"Enter a name to save this as:"
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Save Session",#"Save",nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
UITextField * alertTextField = [alert textFieldAtIndex:0];
alertTextField.keyboardType = UIKeyboardTypeDefault;
alertTextField.placeholder = #"eg. My awesome file...";
alert.tag = 1;
[alert show];
[alert release];
self.name = [[alert textFieldAtIndex:0]text];
}
Apple really doesn't want you messing with UIAlertView. If the way it naturally formats itself doesn't meet your needs, consider putting up a custom presented ("modal") view instead.
This can definitely be achieved, first of all you'll need to set up something like this.
// Create Alert
UIAlertView* av = [UIAlertView new];
av.title = #"Find";
// Add Buttons
[av addButtonWithTitle:#"Cancel"];
[av addButtonWithTitle:#"Find & Bring"];
[av addButtonWithTitle:#"Find & Go"];
[av addButtonWithTitle:#"Go to Next"];
// Make Space for Text View
av.message = #"\n";
// Have Alert View create its view heirarchy, set its frame and begin bounce animation
[av show];
// Adjust the frame
CGRect frame = av.frame;
frame.origin.y -= 100.0f;
av.frame = frame;
// Add Text Field
UITextField* text = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)];
text.borderStyle = UITextBorderStyleRoundedRect;
[av addSubview:text];
[text becomeFirstResponder];

Then you'll want to animate moving the UIAlertView up when the keyboard is called up... something like this...
-(void)keyboardWillShow: (id) notification {
if(showAlert==YES)
{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
[createNewAlert setTransform:CGAffineTransformMakeTranslation(0,-60)];
[createNewAlert show];
[UIView commitAnimations];
}
}
-(void)keyboardWillHide: (id) notification {
if(showAlert==YES)
{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
[createNewAlert setTransform:CGAffineTransformMakeTranslation(0,+60)];
[UIView commitAnimations];
}
}

Of course you can find additional info on custom UIAlertViews in the following Apple sample code!
https://developer.apple.com/library/ios/#samplecode/UICatalog/Introduction/Intro.html
Good Luck!!!!
It's works fine to me. After showing lot of thread finally i found solution
UIAlertView* getWebUrl = [[UIAlertView alloc] initWithTitle:#"Enter URL"
message:nil
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Save",
#"Save Url", nil];
getWebUrl.transform=CGAffineTransformMakeScale(1.0, 0.75);
getWebUrl.alertViewStyle=UIAlertViewStylePlainTextInput;
[getWebUrl show];
and align buttons and textfield after present alertview
-(void)willPresentAlertView:(UIAlertView *)alertView {
for (UIView *view in alertView.subviews) {
if ([view isKindOfClass:[UITextField class]]||
[view isKindOfClass:[UIButton class]] || view.frame.size.height==31) {
CGRect rect=view.frame;
rect.origin.y += 65;
view.frame = rect;
}
}
}
I don't think you can manually resize a UIAlertView, but a trick I use for including a UIActivityIndicatorView is to use "/n" in the message string to make the "message" larger (one extra line per each "/n"), therefore making enough space for everything else.
This is somewhat tricky, Here is the solution for this.You need to use \n in the message string to increase the height of the UIAlertView.
- (IBAction)initiateSave{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Archive"
message:#"\n\n\n\n\n" // Trick to increase the height
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Save Session",#"Save",nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
After increasing the height of Alert, now you can add a label to set the message in the label : "Enter a name to save this as:" at appropriate position.
[alert addSubView: messageLbl];
UITextField * alertTextField = [alert textFieldAtIndex:0];
alertTextField.keyboardType = UIKeyboardTypeDefault;
alertTextField.placeholder = #"eg. My awesome file...";
alert.tag = 1;
[alert show];
[alert release];
self.name = [[alert textFieldAtIndex:0]text];
}
Here, a bit late but should do the trick. (Work for me).
Create UIAlertView
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"TITLE"
message:#"BODY"
delegate:self
cancelButtonTitle:#"CANCEL"
otherButtonTitles:#"OK",#"SEARCH",nil];
alert.tag = kAlertTag;
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
UITextField *alertTextField = [alert textFieldAtIndex:0];
alertTextField.keyboardType = UIKeyboardTypeDefault;
alertTextField.placeholder = #"ENTER STH";
[alert show];
[alert release];
And implement delegate method.
-(void)willPresentAlertView:(UIAlertView *)alertView {
if (alertView.tag == kAlertTag) {
[alertView setFrame:CGRectMake(17, 30, 286, 188)];
NSArray *subviewArray = [alertView subviews];
UILabel *messageLB = (UILabel *)[subviewArray objectAtIndex:2];
[messageLB setFrame:CGRectMake(10, 46, 260, 20)];
UIButton *cancelBT = (UIButton *)[subviewArray objectAtIndex:3];
[cancelBT setFrame:CGRectMake(10, 130, 100, 42)];
UIButton *okBT = (UIButton *)[subviewArray objectAtIndex:4];
[okBT setFrame:CGRectMake(194, 130, 80, 42)];
UIButton *searchBT = (UIButton *)[subviewArray objectAtIndex:5];
[searchBT setFrame:CGRectMake(112, 130, 80, 42)];
UITextField *plateTF = (UITextField *)[subviewArray objectAtIndex:6];
[plateTF setFrame:CGRectMake(10, 80, 266, 50)];
UITextField *placeTF = (UITextField *)[subviewArray objectAtIndex:7];
[placeTF setFrame:CGRectMake(15, 70, 256, 50)];
}
}
FYI [subviewArray objectAtIndex:1] is for title of alertview.
So I'm trying to embed a toggleable (is that a word?) "Do not show this again" button inside a UIAlertView, but I'm running into some trouble that I can't seem to get around.
Here is my non-working code thus far...
EDITED: I added the button's method, and made some changes in the original code. Now I get the button to react to the press but the result is a crash. Any help?
if (![[NSUserDefaults standardUserDefaults] objectForKey:#"disclaimer"]){
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"DISCLAIMER"
message:#"This program is a blah blah"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:#"I Agree", nil];
UILabel *alertLabel = [[UILabel alloc] initWithFrame:CGRectMake(30, 230, 260, 50)];
alertLabel.backgroundColor = [UIColor clearColor];
alertLabel.textColor = [UIColor whiteColor];
alertLabel.text = #"Do not show again";
[alert addSubview:alertLabel];
[alertLabel release];
//declared alertCheckboxButton in the header due to errors I was getting when referring to the button in the button's method below
alertCheckboxButton = [UIButton buttonWithType:UIButtonTypeCustom];
alertCheckboxButton.frame = CGRectMake(200, 247, 16, 16);
alertCheckboxButton.backgroundColor = [UIColor clearColor];
UIImage *alertButtonImageNormal = [UIImage imageNamed:#"checkbox.png"];
UIImage *alertButtonImagePressed = [UIImage imageNamed:#"checkbox-pressed.png"];
UIImage *alertButtonImageChecked = [UIImage imageNamed:#"checkbox-checked.png"];
[alertCheckboxButton setImage:alertButtonImageNormal forState:UIControlStateNormal];
[alertCheckboxButton setImage:alertButtonImagePressed forState:UIControlStateHighlighted];
[alertCheckboxButton setImage:alertButtonImageChecked forState:UIControlStateSelected];
[alertCheckboxButton addTarget:self action:#selector(alertCheckboxButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
//made the button a subview of alert rather than alertLabel
[alert addSubview:alertCheckboxButton];
[alert show];
//moved alertCheckboxButton release to (void)dealloc
[alert release];
}
-(void)alertCheckboxButtonClicked{
if (![[NSUserDefaults standardUserDefaults] objectForKey:#"disclaimer"]){
[[NSUserDefaults standardUserDefaults] setBool:TRUE forKey:#"disclaimer"];
alertCheckboxButton.selected = YES;
}else {
[[NSUserDefaults standardUserDefaults] removeObjectForKey:#"disclaimer"];
alertCheckboxButton.selected = NO;
}
}
If you want to make this button as toggle then assign a tag to this button, then in its event function check for tag if it is 0 then set it to 1 and also set a BOOL there. When you are adding it to alert then check for the BOOL value if that is true change you button image and tag also.
DUH! My code works. Just had to delete the : in #selector(alertCheckboxButtonClicked:)
Isn't it always something simple?
I think you simply want to toggle the "selected" property of the UIControl. When "selected" is YES is when the image for UIControlStateSelected will be used...
The typical iOS equivalent of a checkbox is the UISwitch, with it's "on" property.
//---------Searchoing----- //
- (IBAction) Search_hadit
{
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:#"Search"
message:#" "
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Search",
nil];
CGRect frame = CGRectMake(14, 35, 255, 23);
myTextField = [[UITextField alloc] initWithFrame:frame];
myTextField.borderStyle = UITextBorderStyleBezel;
myTextField.textColor = [UIColor blackColor];
myTextField.textAlignment = UITextAlignmentCenter;
myTextField.font = [UIFont systemFontOfSize:14.0];
myTextField.placeholder = #"Enter Query";
myTextField.backgroundColor = [UIColor whiteColor];
myTextField.autocorrectionType = UITextAutocorrectionTypeNo; // no auto correction support
myTextField.keyboardType = UIKeyboardTypeDefault;// use the default type input method (entire keyboard)
myTextField.returnKeyType = UIReturnKeyDone;
myTextField.delegate = self;
myTextField.clearButtonMode = UITextFieldViewModeWhileEditing; // has a clear 'x' button to the right
[alert addSubview:myTextField];
[alert show];
[alert release];
}
When I click search button in my app alert view show...
I want when user click search button I get the text which he enter and send this data to another function on as he click search button where I can perform search. Any idea?
I guess (acording to the title) you'll need an UIAlertViewDelegate or at least the function:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
NSString* buttonTitle = [alertView buttonTitleAtIndex:buttonIndex];
if ([buttonTitle equalToString:#"Search"]) {
[do something];
}
}
But the text in your description describes a different problem than your title. I can't provide a solution to that, though.
I'm trying to add a new cell to a tableview, and pop up an alert with a UITextField to allow the user to input the title they wish to give the new cell. I have code to pop up an alert with a UITextField when the "+" button is pressed, and the code to add a new cell, however I don't know how to get the text from the UITextField to insert it into the cell's title.
This is my code to pop up the alert:
UIAlertView* alertPopUp = [[UIAlertView alloc] init];
[alertPopUp setDelegate:self];
[alertPopUp setTitle:#"Enter event title"];
[alertPopUp setMessage:#" "];
[alertPopUp addButtonWithTitle:#"Cancel"];
[alertPopUp addButtonWithTitle:#"OK"];
UITextField * eventNameField = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)];
[eventNameField setBackgroundColor:[UIColor whiteColor]];
[alertPopUp addSubview:eventNameField];
[alertPopUp show];
and my alertView action is:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
NSString *buttonTitle=[alertView buttonTitleAtIndex:buttonIndex];
if([buttonTitle isEqualToString:#"Cancel"]) {
return;
}
else if([buttonTitle isEqualToString:#"Ok"]) {
}
}
What can I do to get the text from eventNameField when "Ok" is pressed and add it to a mutablearray named eventList? Thanks!
Set the tag on eventNameField to something meaningful
eventNameField.tag = 1001;
Then inside of the alertViewDelegate you can get the TextField by using - [UIView viewWithTag:]
UITextField* textField = (UITextField*)[alertView viewWithTag:1001];
eventNameField.text should give you the value
//declare the array
NSMutableArray* eventList = [NSMutableArray array];
//set its value
[eventList addObject:eventNameField.text];
DHamrick probably has the better solution, but found one more that could work.
You can get all the subviews inside alertView with [alertView subviews] (returns a NSCFArray), then you just have to find the one that is of class UITextField, in your case you could get it with:
[[[alertView subviews] objectAtIndex:4] text]
The old answers don't take advantage of changes in UIAlertView.
In iOS 5 and beyond, there is an easier way of using UITextfield on an alert view:
UIAlertView *alertPopUp = [[UIAlertView alloc] initWithTitle:#"Enter event title" message:#"" delegate:nil cancelButtonTitle:#"Cancel" otherButtonTitles:#"OK", nil];
alertPopUp.alertViewStyle = UIAlertViewStylePlainTextInput;
self.alertTextField = [message textFieldAtIndex:0];
self.alertTextField.keyboardType = UIKeyboardTypeAlphabet;
alertPopUp.delegate = self;
[alertPopUp show];
[self.alertTextField becomeFirstResponder];
where alertTextField was set up like this:
#propery (nonatomic, strong) UITextField *alertTextField;
Then you can access alertTextField in your delegate response:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
NSString *buttonTitle=[alertView buttonTitleAtIndex:buttonIndex];
if([buttonTitle isEqualToString:#"Cancel"]) {
return;
}
else if([buttonTitle isEqualToString:#"Ok"]) {
NSLog(#"your text string is %#", self.alertTextField.text);
}
}
You could also just give the alertView a unique tag, and compare tag numbers, rather than save a reference to it using #property.
