I just built an Activity indicator view, and a popup page in Xcode. How can I get a 3 second delay in Activity indicator view, then switch to popup page?
here is my Viewcontroller.m
- (IBAction)Connect:(UIButton *)sender forEvent:(UIEvent *)event
{
[self performSelector:#selector(delay2) withObject:Nil afterDelay:6.0];
[self performSelector:#selector(delay1) withObject:ConnectAct afterDelay:0.0];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"LP01;" message:#"No Connection" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:#"Help", nil];
[alert show];
}
- (IBAction)ConnectLP02:(UIButton *)sender
{
[self performSelector:#selector(delay2) withObject:Nil afterDelay:6.0];
[self performSelector:#selector(delay1) withObject:ConnectAct afterDelay:0.0];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"LP02;" message:#"No Connection" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:#"Help", nil];
[alert show];
}
- (void)delay1 {
ConnectAct.alpha = 1.0;
}
- (void)delay2 {
}
- (IBAction)ConnectLP02:(UIButton *)sender
{
[self performSelector:#selector(delay2) withObject:Nil afterDelay:6.0];
[self performSelector:#selector(delay1) withObject:ConnectAct afterDelay:0.0];
}
- (void)delay1 {
ConnectAct.alpha = 1.0;
}
- (void)delay2 {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"LP02;" message:#"No Connection" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:#"Help", nil];
[alert show];
}

enter code hereI am having trouble with going back to the previous view controller when alert is presented.
What I am trying to do is have the user enter in data, then an alert appear saying it was successful, then return to the previous view controller.
I currently have no code doing so and am seeking assistance with what I should put in.
- (IBAction)saveLabel:(id)sender
{
NSArray *data = [[NSUserDefaults standardUserDefaults] objectForKey:#"DATA"];
NSMutableArray *currentDataArray;
if (data == nil)
{
currentDataArray = [[NSMutableArray alloc]init];
}
else
{
currentDataArray = [[NSMutableArray alloc]initWithArray:data];
}
[currentDataArray addObject:self.textField.text];
[[NSUserDefaults standardUserDefaults] setObject:currentDataArray forKey:#"DATA"];
}
- (IBAction)enterButtonPressed:(id)sender
{
NSLog(#"enterButtonPressed");
UIAlertView *enterAlert = [[UIAlertView alloc]initWithTitle:nil message:#"Entry was recorded" delegate:nil cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];
[enterAlert show];
}
//If u r using dismissing
[self dismissViewControllerAnimated:YES completion:^{
UIAlertView *enterAlert = [[UIAlertView alloc]initWithTitle:nil message:#"Entry was recorded" delegate:nil cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];
[enterAlert show];
}];
//if u r using navigation ,popViewController
[CATransaction begin];
[CATransaction setCompletionBlock:^{
// handle completion here
UIAlertView *enterAlert = [[UIAlertView alloc]initWithTitle:nil message:#"Entry was recorded" delegate:nil cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];
[enterAlert show];
}];
[self.navigationController popViewControllerAnimated:YES];
[CATransaction commit];
Set Delegate self of your UIAlertView
UIAlertView *enterAlert = [[UIAlertView alloc]initWithTitle:nil message:#"Entry was recorded" delegate:self cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];
[enterAlert show];
Use Delegate Method of UIAlertviewController.
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex==0){
// Do your Stuff Here....
[self.navigationController popViewControllerAnimated:TRUE];
}
}
Add the following UIAlertViewDelegate method to your implementation file:
- (void)alertView:(UIAlertView *)alertView
didDismissWithButtonIndex:(NSInteger)buttonIndex {
// If you are presenting this view controller
[self dismissViewControllerAnimated:YES completion:nil];
// If you are pushing this view controller
[self.navigationController popViewControllerAnimated:YES];
}
Also remember to set your UIAlertView delegate to your view controller, change to the following code:
UIAlertView *enterAlert = [[UIAlertView alloc]initWithTitle:nil message:#"Entry was recorded" delegate:self cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];
UIAlertView *enterAlert = [[UIAlertView alloc]initWithTitle:nil message:#"Entry was recorded" delegate:nil cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];
enterAlert.tag=100;
[enterAlert show];
}
-(void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
if (alertView.tag == 100) {
if (buttonIndex == 0) {
// Do something when ok pressed
// If you are presenting this view controller
[self dismissViewControllerAnimated:YES completion:nil];
// If you are pushing this view controller
[self.navigationController popViewControllerAnimated:YES];
} else {
// Do something for other alertviewButton}
else{// Do something with responses from other alertViews by giving tags
}
I have one alert view and when I click on yes button it is supposed to produce another alert view and a toast message,but it is not happening. I couldn't figure it out. Here is my code:
-(void)myMethod {
UIAlertView *saveAlert = [[UIAlertView alloc] initWithTitle:#"First Message"
message:#"My First message"
delegate:nil
cancelButtonTitle:#"No"
otherButtonTitles:#"Yes", nil];
saveAlert.tag=0;
[saveAlert performSelectorOnMainThread:#selector(show) withObject:nil waitUntilDone:NO];
}
This is the method I am using to provide the functionality for different alert views.
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(alertView.tag==0) {
if (buttonIndex == 0)
{
//Code for Cancel button
}
if (buttonIndex == 1)
{
//code for yes button
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.navigationController.view animated:YES];
hud.mode = MBProgressHUDModeText;
hud.labelText = #"Successfully displayed First Message";
hud.margin = 10.f;
hud.yOffset = 150.f;
hud.removeFromSuperViewOnHide = YES;
[hud hide:YES afterDelay:3];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Second Message"
message:#"My second message"
delegate:nil
cancelButtonTitle:#"No"
otherButtonTitles:#"Yes",nil];
alert.tag=1;
[alert performSelectorOnMainThread:#selector(show) withObject:nil waitUntilDone:YES];
}
}
if (alertView.tag==1) {
if (buttonIndex == 0)
{
//Code for Cancel button
}
if (buttonIndex == 1)
{
//Code for yes Button
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.navigationController.view animated:YES];
hud.mode = MBProgressHUDModeText;
hud.labelText = #"Succesfully displayed Second Message";
hud.margin = 10.f;
hud.yOffset = 150.f;
hud.removeFromSuperViewOnHide = YES;
[hud hide:YES afterDelay:3];
}
}
}
Can anyone help in finding the issue. Why I cannot get my second alert after clicking yes button in first alert?
You have not set the delegate for your UIAlertView and also make sure your delegate conforms to UIAlertViewDelegate protocol. Find the code snippet below.
You controller conforms to UIAlertViewDelegate protocol:
#interface YourViewController : UIViewController <UIAlertViewDelegate>
Create UIAlertView and set the deleagte:
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"First Message"
message:#"Show second message"
delegate:self
cancelButtonTitle:#"No"
otherButtonTitles:#"Yes", nil];
[alertView show];
Implement UIAlertViewDelegate delegate method:
- (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if( 0 == buttonIndex ){ //cancel button
[alertView dismissWithClickedButtonIndex:buttonIndex animated:YES];
} else if ( 1 == buttonIndex ){
[alertView dismissWithClickedButtonIndex:buttonIndex animated:YES];
UIAlertView * secondAlertView = [[UIAlertView alloc] initWithTitle:#"Second Message"
message:#"Displaying second message"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[secondAlertView show];
}
}
You are specifying nil as the delegate for your alert views. You need to specify an object so the alertView:clickedButtonAtIndex: method can be called!
If you'd like to handle this more clear, you could use a block-based AlertView.
Create new file->Subclass of->UIAlertView
SuperAlertView.h
#import <UIKit/UIKit.h>
#class MySuperAlertView;
typedef void (^MySuperAlertViewBlock) (MySuperAlertView *alertView);
#interface MySuperAlertView : UIAlertView
- (instancetype) initWithTitle:(NSString *)title message:(NSString *)message;
- (void) addButtonWithTitle:(NSString *)buttonTitle block:(MySuperAlertViewBlock) block;
#end
SuperAlertView.m
#import "MySuperAlertView.h"
#interface MySuperAlertView()<UIAlertViewDelegate>
#property NSMutableArray *blocks;
#end
#implementation MySuperAlertView
- (instancetype)initWithTitle:(NSString *)title message:(NSString *)message
{
if (self = [super initWithTitle:title message:message delegate:self cancelButtonTitle:nil otherButtonTitles:nil])
{
self.blocks = [NSMutableArray array];
}
return self;
}
- (void)addButtonWithTitle:(NSString *)buttonTitle block:(MySuperAlertViewBlock)block
{
[self addButtonWithTitle:buttonTitle];
[self.blocks addObject:block ? [block copy] : [NSNull null]];
}
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
MySuperAlertViewBlock block = self.blocks[buttonIndex];
if ((id) block != [NSNull null]){
block(self);
}
}
#end
Usage:
MySuperAlertView *alertView = [[MySuperAlertView alloc] initWithTitle:#"Info" message:NSLocalizedString(#"EMAIL_SENT_SUCCESSFULL", nil)];
[alertView addButtonWithTitle:#"Ok" block:^(MySupertAlertView *alertView) {
// handle result from ok button here
}];
[alertView addButtonWithTitle:#"cancel" block:NULL];
dispatch_async(dispatch_get_main_queue(), ^{
[alertView show];
});
I am trying to use UIAlertView to pull up a get ready title then pull it off the screen to let the player know the game is starting. How do I do this using UIAlertView?
Try this Methods...
UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:#"Get Ready!" message:nil delegate:nil cancelButtonTitle:nil otherButtonTitles:nil];;
[alertView show];
[self performSelector:#selector(dismissReadyAlert:) withObject:alertView afterDelay:3.0];
-(void)dismissReadyAlert:(UIAlertView *)alertView
{
[alertView dismissWithClickedButtonIndex:0 animated:NO];
alertView.title = #"Your game is started!";
[alertView show];
[self performSelector:#selector(dismissStartAlert:) withObject:alertView afterDelay:2.0];
}
-(void)dismissStartAlert:(UIAlertView *)alertView
{
[alertView dismissWithClickedButtonIndex:0 animated:YES];
}
Thanks!
You need to keep a reference to the alert. Then just call this method:
[alert dismissWithClickedButtonIndex:0 animated:YES];
Declare UIAlertView Object in header file.
UIAlertView *alertReady;
Then Display alertview whenever you like to display and call one method to dismiss alertview
alertReady = [[UIAlertView alloc] initWithTitle:#"Alert" message:#"Get Ready" delegate:nil cancelButtonTitle:nil otherButtonTitles: nil];
[alertReady show];
[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:#selector(hideAlertView) userInfo:nil repeats:NO];
-(void)hideAlertView
{
[alertReady dismissWithClickedButtonIndex:0 animated:YES];
}
-(IBAction) secondTwoSlotSettings: (id)sender{
UIAlertView *secondTwoSlotSettings = [[UIAlertView alloc] initWithTitle:#""
message:#""
delegate:self
cancelButtonTitle:#"キャンセル"
otherButtonTitles:#"2スロット カメラ",#"2スロット カメラロール", nil];
[secondTwoSlotSettings show];
}
-(IBAction) firstTwoSlotSettings: (id)sender{
UIAlertView *firstTwoSlotSettingsMessage = [[UIAlertView alloc] initWithTitle:#""
message:#""
delegate:self
cancelButtonTitle:#"キャンセル"
otherButtonTitles:#"1スロット",#"２スロット", nil];
[firstTwoSlotSettingsMessage show];
}
-(IBAction) oneSlotSettings: (id)sender{
UIAlertView *oneSlotSettingsMessage = [[UIAlertView alloc] initWithTitle:#""
message:#""
delegate:self
cancelButtonTitle:#"キャンセル"
otherButtonTitles:#"カメラ",#"カメラロール", nil];
[oneSlotSettingsMessage show];
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSString *title = [alertView buttonTitleAtIndex:buttonIndex];
if([title isEqualToString:#"キャンセル"])
{
NSLog(#"キャンセル was selected.");
}
else if([title isEqualToString:#"はい"])
{
NSLog(#"はい was selected.");
}
else if([title isEqualToString:#"2スロット カメラ"])
{
NSLog(#"2スロット カメラ was selected.");
}
else if([title isEqualToString:#"1スロット"])
{
NSLog(#"1スロット was selected.");
}
else if([title isEqualToString:#"2スロット"])
{
NSLog(#"2スロット was selected.");
UIAlertView *oneSlotSettingsMessage = [[UIAlertView alloc] initWithTitle:#""
message:#""
delegate:self
cancelButtonTitle:#"キャンセル"
otherButtonTitles:#"2スロット カメラ",#"2スロット カメラロール", nil];
[oneSlotSettingsMessage show];
}
else if([title isEqualToString:#"カメラ"])
{
NSLog(#"カメラ was selected.");
}
else if ([title isEqualToString:#"カメラロール"])
{
NSLog(#"カメラロール was selected.");
}
Here is my code:
I was only able to show the firstTwoSlotSettings and oneSlotSettings. but when I try to show the secondTwoSlotSettings it vanish.
No It is not possible with Apple's UIAlertView. When you present an alertView ,it will come modal to all other views and dismiss any other Alerts already present in the screen.
One thing you can do is to create a custom View as your alert and animates its present/dismiss action? Then you have the control to do whatever you want..
I use this code to share to facebook:
[appDelegate.facebook dialog:#"feed" andParams:params andDelegate:appDelegate];
How can i get the notification (like sharekit) when sharing is successful?
I want to show UIAlertView but i do not know which facebook method that i need to put the UIAlertView.
I try in this method:
- (void)dialogDidSucceed:(NSURL *)url {
if ([_delegate respondsToSelector:#selector(dialogCompleteWithUrl:)]) {
[_delegate dialogCompleteWithUrl:url];
}
UIAlertView * alert=[[UIAlertView alloc]
initWithTitle: #"Sharing to Facebook"
message: #"Success"
delegate:self
cancelButtonTitle:#"Close"
otherButtonTitles:nil, nil];
[self setAlertSuccess:alert];
[alertSuccess show];
[alert release];
NSLog(#"SUCCESS 2");
[self dismissWithSuccess:YES animated:YES];
}
It is working however, when i click cancel button, this method is also called. So where is the right one to put the success alert view?
I am new in IOS.
These are changes i made in FBDialog.m
- (void)dismissWithSuccess:(BOOL)success animated:(BOOL)animated {
if (success) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Facebook Login Sucessful!" message:#"" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
[alert release];
if ([_delegate respondsToSelector:#selector(dialogDidComplete:)]) {
[_delegate dialogDidComplete:self];
}
} else {
if ([_delegate respondsToSelector:#selector(dialogDidNotComplete:)]) {
[_delegate dialogDidNotComplete:self];
}
}
[self dismiss:animated];
}
