How to create a pop up animation on iPhone? I want show my uiview as a popup view, like uialertview design.
- (void) killHUD
{
[alertView dismissWithClickedButtonIndex:0 animated:YES];
[alertView release];
alertView = nil;
}
- (void)presentSheet:(NSString *)message withFrame:(CGRect)frame
{
if(!alertView)
{
alertView = [[CustomAlertView alloc] initWithFrame:frame onView:self.window];
alertView.autoresizingMask = UIViewAutoresizingFlexibleBottomMargin;
[alertView setNeedsDisplay];
[alertView setText:message];
[alertView show];
}
}
You can use these functions creaed by me to show an hide the loading animation popup..
Happy Coding..

I've added UITextView as a sub view of UIAlertView, I've added UIToolBar with a Done button (using UIBarButtonItem) as inputAccessoryView to allow user to resign keyboard`. It's just working fine in iOS6.0. And not in iOS5.0.
I've break point and checked in all the way I can, for reconfirming my self, I've made a sample project and checked the same in both the iOS versions, and the problem is same.
Here's the code, that's messing with me,
-(UIToolbar *)accessoryView
{
if (!accessoryView) {
accessoryView = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 44.0)];
UIBarButtonItem *btn = [[UIBarButtonItem alloc]initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(hideKeyBoard)];
UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:nil
action:nil];
accessoryView.items = [NSArray arrayWithObjects:flexibleSpace,btn, nil];
[accessoryView setTintColor:[[UIColor blackColor]colorWithAlphaComponent:0.5]];
}
return accessoryView;
}
-(IBAction) showAlertWithTextView: (id) sender
{
UIAlertView *alert = [[UIAlertView alloc] initWithFrame:CGRectMake(0, 50, 320, 200)];
alert.title = nil;
alert.message = nil;
alert.delegate = self;
//textview I've added in .h file
textView = [[UITextView alloc] initWithFrame:alert.bounds];
textView.text = #"This is a UITextView";
textView.keyboardAppearance = UIKeyboardAppearanceAlert;
textView.editable = YES;
textView.inputAccessoryView = [self accessoryView];
[alert addSubview:textView];
[alert show];
}
- (void)hideKeyBoard {
[textview resignFirstResponder];
//[self.view endEditing:YES]; //this is also not worked
}
Here's list of steps I'm doing,
Showing Alert with Textview
Focus to Textview
Tap on Done button to resign TextView
Its not resigning in iOS5 but resigning in iOS6
Any idea? What's going wrong?
Actually your textview is not the first responder. The first responder is your alertView.
So you should try this....
[textField resignFirstResponder];
[alertView resignFirstResponder];
To use this code you must declare your alertView object in your.h file
I've solved it, as solution given by #iOS Developer, but as I've so many UIAlertView objects to handle, I've added a property of UIAlertView in delegate, and assigning it with the object of my alertview like this,
-(void)willPresentAlertView:(UIAlertView *)alertView
{
//set current alertview
[[AppDelegate sharedDelegate] setCurrentAlertView:alertView];
}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
//will remove current alertview reference
[[AppDelegate sharedDelegate] setNilCurrentAlertView];
}
- (void)hideKeyBoard {
[textView resignFirstResponder];
//when need to resign UITextView, get current alertview object
UIAlertView *alertView = [[AppDelegate sharedDelegate] getCurrentAlertView];
if(alertView) {
[alertView resignFirstResponder];
}
}
In AppDelegate.m file,
#pragma mark - UIAlertView Resign
- (void) setCurrentAlertView:(UIAlertView *)alert{
self.alertObj = alert;
}
- (void) setNilCurrentAlertView {
self.alertObj = nil;
}
- (UIAlertView *)getCurrentAlertView {
return (UIAlertView *)self.alertObj;
}
As it is somewhat late but I am wondering that your code will not work in iOS7 or not as from iOS7 onwards UIAlertView is not allowing to add any subview (As you are adding UITextView as subview of UIAlertView).
If your requirement is not to compulsory using the UITextView then you can use UIAlertView with following configuration with default textfield in alert.
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"Title"
message:#"Message"
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Ok", nil];
[message setAlertViewStyle:UIAlertViewStylePlainTextInput];
[message show];
And you can get value of this textfield in delegate of UIAlertView like this,
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
[alertView textFieldAtIndex:0].text;
}
I have 3 buttons in my UIActionsheet.
I want one cancel button at the bottom of it.
I also want that all of the buttons should be able to dismiss UIActionsheet.
Currently, none of them does the job for me.
Here is how I display it:
UIActionSheet *actionSheet = nil;
NSArray *otherButtons = nil;
otherButtons = [NSArray arrayWithObjects:#"Button1", #"Button2", #"Button3",
nil];
actionSheet = [[UIActionSheet alloc] initWithTitle:title
delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil, nil];
for( NSString *btntitle in otherButtons)
{
[actionSheet addButtonWithTitle:btntitle];
}
[actionSheet addButtonWithTitle:#"Cancel"];
actionSheet.cancelButtonIndex = actionSheet.numberOfButtons - 1;
actionSheet.actionSheetStyle = UIActionSheetStyleDefault;
[actionSheet showInView:self.view];
In my delegate, I do this:
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
//some code
[actionSheet dismissWithClickedButtonIndex:buttonIndex animated:YES];
}
But it does not dismiss. I do not want to change my design and position of any buttons.
What should I do?
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
[actionSheet dismissWithClickedButtonIndex:buttonIndex animated:YES];
[self performSelector:#selector(OtherOperations) withObject:nil afterDelay:0.0];
}
-(void)OtherOperations{ //some code
}
Be careful when opening an action sheet from a lpgr. Only open it on "Began", not again on "Ended".
- (void) handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{
CGPoint p = [gestureRecognizer locationInView:self.tblYourVids];
if (gestureRecognizer.state == UIGestureRecognizerStateBegan) {
NSIndexPath *indexPath = [self.aTable indexPathForRowAtPoint:p];
if (indexPath == nil)
NSLog(#"long press on table view but not on a row");
else {
NSLog(#"long press on table view at row %d", indexPath.row);
self.selectedCell = [self.aTable cellForRowAtIndexPath:indexPath];
DLog(#"open action sheet only once");
[self showActionSheet];
}
} else if (gestureRecognizer.state == UIGestureRecognizerStateEnded) {
// eat this one
}
}
you have to add this to yours .h file.
<UIActionSheetDelegate>
Also add this line to yours .m file.
actionSheet.delegate = self;
Let me know, this is working or not. If works, accept it as right answer
just try to use the below code.it will automatically dismiss.
UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:#""
delegate:self
cancelButtonTitle:#"cancel"
destructiveButtonTitle:#"Printer"
otherButtonTitles: nil];
[sheet showInView:self.view];
[sheet release];
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
}
let me know whether it is working or not
Happy Coding!!!!!
This is not the right way to cancel UIActionSheet firstly you have to disable to default UIActionSheet by javascipt
and go through this web

I'm using the following inside a button click or (IBAction)
- (IBAction)HistoryBtn:(id)sender {
self startReport];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
//============================
so some long processing code
//============================
[self stopReport];
});
}
Where
-(void) startReport
{
alert = [[UIAlertView alloc] initWithTitle:#"Generating PDF" message:#" " delegate:self cancelButtonTitle:nil otherButtonTitles:nil];
UIActivityIndicatorView *progress= [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(125, 50, 30, 30)];
progress.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;
[alert addSubview:progress];
[alert setDelegate:self];
[progress startAnimating];
[alert show];
}
-(void) stopReport
{
NSLog(#" Stop Called ");
[self.alert dismissWithClickedButtonIndex:0 animated:NO];
self.alert = nil;
NSLog(#" Stop Called ");
}
The problem is The AlertView popups up and I can see the button work, then StopReport IS called But the AlertView stays there How can I get the AlertView to go away
Thanks in advance
You must work with the UI only on the main thread.
- (IBAction)HistoryBtn:(id)sender {
self startReport];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
//============================
so some long processing code
//============================
dispatch_async(dispatch_get_main_queue(), ^{
[self stopReport];
});
});
}
I have one UIAlertView containing one UITextField with ok and cancel button. When I click on ok button i am calling webService. I want to return keyboard before calling webservice. Keyboard is not returning till response is not coming from webservice. Because of that half screen not visible to user during loading webservice. Here is my code which i did.
UIAlertView *alertview = [[UIAlertView alloc] initWithTitle:#"Forgot Password" message:#" " delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"OK", nil];
// Adds a username Field
alertEmailtextfield = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 29.0)];
alertEmailtextfield.layer.cornerRadius = 07.0f;
[alertEmailtextfield setBorderStyle:UITextBorderStyleRoundedRect];
alertEmailtextfield.placeholder = #"Enter Email";
[alertEmailtextfield setBackgroundColor:[UIColor whiteColor]];
alertEmailtextfield.autocapitalizationType =UITextAutocapitalizationTypeNone; //For Making Caps Off
[alertview addSubview:alertEmailtextfield];
[alertview show];
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 1) {
if ([alertEmailtextfield.text length] != 0) {
if (![self validEmail:alertEmailtextfield.text]) {
[AlertView UIAlertView:#"Enter email is not correct"];
}else{
//[alertEmailtextfield resignFirstResponder];
[NSThread detachNewThreadSelector:#selector(startSpinner) toTarget:self withObject:nil];
Boolean isForgotPassword = [serverConnection forgotPassword:alertEmailtextfield.text];
if (isForgotPassword) {
NSLog(#"Mail is send");
[AlertView UIAlertView:#"New password is send to your mail"];
[spinner stopAnimating];
}else{
[AlertView UIAlertView:#"User does not exist"];
[spinner stopAnimating];
}
}
}else{
[AlertView UIAlertView:#"Text Field should not be empty"];
}
}
}
Please if any one knows how to return keyboard in UIAlertView's UITextField, help me.
Your UI is stuck waiting for your webservice to complete. Call your webservice in a background thread your problem will be solved.
[self performSelectorInbackgroundThread:#selector(yourWebservice)];
Might be u are doing both task (webservice call and keyboard resinging) in same main thread so untill ur data is not loading from server keyboard is not resign from view. call weservice method in background thread like.
-(void)alertView:(CustomAlert *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
[textField resignFirstResponder];
UPdate
[self performSelectorInBackground:#selector(yourWebservice) withObject:nil];
}
Hey guys, I'm having trouble obtaining the value/text from a AlertView TextField. Maybe someone can look at my code and see what I'm doing wrong. Every time I press OK, the label get's a (null) value. I must be missing something here.
TextFieldINAlertViewController.h
#import <UIKit/UIKit.h>
#interface TextFieldInAlertViewController : UIViewController {
UITextField *myTextField;
IBOutlet UILabel *labelView;
NSString *FieldStr1;
}
#property (nonatomic, copy) NSString *FieldStr1;
#end
TextFieldInAlertViewController.m
#import "TextFieldInAlertViewController.h"
#implementation TextFieldInAlertViewController
#synthesize FieldStr1;
- (void)viewDidLoad {
[super viewDidLoad];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Enter Name Here" message:#"blank" delegate:self cancelButtonTitle:#"Dismiss" otherButtonTitles:#"OK!", nil];
UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12, 45, 260, 25)];
CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0, 60);
[alert setTransform:myTransform];
[myTextField setBackgroundColor:[UIColor whiteColor]];
[alert addSubview:myTextField];
[alert show];
[alert release];
}
-(void)alertView:(UIAlertView *)alert clickedButtonAtIndex:(NSInteger)index
{
if (index == 0){
return;
}
if (index == 1){
FieldStr1 = myTextField.text;
labelView.text = [NSString stringWithFormat:#"%#" , FieldStr1 ];
}
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
- (void)viewDidUnload {
}
- (void)dealloc {
[super dealloc];
}
#end
myTextField is a local variable in viewDidLoad, but it's also a member variable in your class. Get rid of the local declaration, and you should be fine. Also, I'd move this code to viewDidAppear:, rather than viewDidLoad.
Since iOS5 you can use property on the alertView which is a much simplier way to add a textField.
If you want to add a TextField to an UIAlertView, you can use this property (alertViewStyle) for UIAlertView:
- (void)showAlert{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Title" message:#"Message" delegate:self cancelButtonTitle:#"Done" otherButtonTitles:nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
((UITextField *) [alertView textFieldAtIndex:0]).text = #"Default Value";
[alert show];
}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
NSLog(#"%#", [alertView textFieldAtIndex:0].text);
}
Check UIAlertView reference: http://developer.apple.com/library/ios/#documentation/uikit/reference/UIAlertView_Class/UIAlertView/UIAlertView.html
