I have a UISegmentControl that select nothing through IB, after the user selects the segment it becomes selected. How do i do it so that it doesnot gets selected?
//Show question method
-(void)question:(NSInteger)i
{
// Path to the plist
NSString *path = [[NSBundle mainBundle] pathForResource:#"Question" ofType:#"plist"];
// Set the plist to an array
NSArray *array = [NSArray arrayWithContentsOfFile:path];
//Check the number of entries in the array
NSInteger numCount = [array count];
if(i <numCount)
{ NSDictionary *dict = [array objectAtIndex:i];//load array index 0 dictionary data
self.title = [NSString stringWithFormat:#"Question %d", i+1];//set the nav bar title
quest.text = [dict valueForKey:#"Question"];//Set the Question to storage
ans.text = [dict valueForKey:#"Answer"];//Set the Answer to storage
NSInteger option = [[dict valueForKey:#"NumberOfOption"] integerValue ];//Check options to determine the question type
//check if the option is is a QRCode or Multiple Choices Question
if (option ==0)
{
QRbutton.alpha = 1; //show the QR Code Button If there is no options
OptionsAnswer.alpha = 0;//Hide Option if there is no options
}
else
{
QRbutton.alpha = 0.0;//Hide QR Code Button if there is options
OptionsAnswer.alpha = 1;//Show Option if there is options
[OptionsAnswer setTitle:[dict valueForKey:#"Option1"] forSegmentAtIndex:0];//Set Option Answer Value
[OptionsAnswer setTitle:[dict valueForKey:#"Option2"] forSegmentAtIndex:1];//Set Option Answer Value

[OptionsAnswer setTitle:[dict valueForKey:#"Option4"] forSegmentAtIndex:3];//Set Option Answer Value
[OptionsAnswer addTarget:self action:#selector(OptionAnswerCheck) forControlEvents:UIControlEventValueChanged];//Call action when options is being selected
}
}
else {
//if question is all answered, it will prompt an alert for end game video.
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:#"Well Done"
message:#"You Have Answered All The Questions, Oh Wait A Minute I Heard A Cracking Sound...." delegate:self

Just search for setMomentary: in your developer documentation inside Xcode.
I'm not entirely sure what you're asking here, but I think that you want to set the momentary property toYES.
The property is in the inspector of IB as well. (Can't post a screenshot, I'm on my iPhone).

I'm trying to display two objects or "classNames" into a PFQueryTableViewController. Here is my code so far with only one object. I can't seem to be able to add more than one object.
-(id)initWithCoder:(NSCoder *)aDecoder {
self = [super initWithCoder:aDecoder];
if (self) {
// Customize the table
// The className to query on
self.className = #"Funny";
//self.className = #"Story";
// The key of the PFObject to display in the label of the default cell style
self.textKey = #"title";
// Whether the built-in pull-to-refresh is enabled
self.pullToRefreshEnabled = YES;
// Whether the built-in pagination is enabled
self.paginationEnabled = YES;
// The number of objects to show per page
self.objectsPerPage = 100;
}
return self;
}
Just add more #propertys to your view controller. Make sure to add the necessary ones (className2, textKey2, etc) and to modify the datasource methods of your table view to display the data.
That being said, it seems strange the the view controller is initiated with initWithCoder. That is usually the method invoked by storyboard for views.
I used two object when saving the post. It worked perfectly!
PFObject *quoteNew = [PFObject objectWithClassName:#"New"];
[quoteNew setObject:[[self attribution] text] forKey:#"by"];
[quoteNew setObject:[[self quoteText] text] forKey:#"quoteText"];
[quoteNew setObject:[[self attributionTitle] text] forKey:#"title"];
[quoteNew saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (!error) {
[self done:self];
} else {
[[[UIAlertView alloc] initWithTitle:#"Uh oh. Somthing went wrong"
message:[[error userInfo] objectForKey:#"error"]
delegate:nil
cancelButtonTitle:#"Ok"
otherButtonTitles: nil] show];
}
}];
PFObject *quote = [PFObject objectWithClassName:#"Funny"];
[quote setObject:[[self attribution] text] forKey:#"by"];
[quote setObject:[[self quoteText] text] forKey:#"quoteText"];
[quote setObject:[[self attributionTitle] text] forKey:#"title"];
[quote saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (!error) {
[self done:self];
} else {
[[[UIAlertView alloc] initWithTitle:#"Uh oh. Somthing went wrong"
message:[[error userInfo] objectForKey:#"error"]
delegate:nil
cancelButtonTitle:#"Ok"
otherButtonTitles: nil] show];
}
}];
}
In my project I want to show the events and offers through push notification, but the problem is, I'm able to show the events or offers, not both. Is there any way to identify the message of Push notification. Here's the code:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
NSString *message = nil;
id alert = [userInfo objectForKey:#"alert"];
if ([alert isKindOfClass:[NSString class]]) {
message = alert;
} else if ([alert isKindOfClass:[NSDictionary class]]) {
message = [alert objectForKey:#"body"];
}
if (alert) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Title"
message:#"AThe message." delegate:self
cancelButtonTitle:#"button 1"
otherButtonTitles:#"button", nil];
[alertView show];
}
NSString *contentsInfo = [userInfo objectForKey:#"contTag"];
NSLog(#"Received contents info : %#", contentsInfo);
NSString *nibName = [AppDelegate fetchNibWithViewControllerName:#"EventsViewController"];
EventsViewController *evc = [[EventsViewController alloc] initWithNibName:nibName bundle:nil];
evc.newEvent = YES;
[self.navigationController pushViewController:evc animated:YES];
[UIApplication sharedApplication].applicationIconBadgeNumber = [[[userInfo objectForKey:#"aps"] objectForKey: #"badgecount"] intValue];
}
alert is always an NSDictionary with two keys: body and show-view. The value of the former is the alert message and the latter is a Boolean (false or true). If false, the alert’s View button is not shown. The default is to show the View button which, if the user taps it, launches the application.
check the docs
To identify type of the message you can provide additional fields, as described here
Example:
{
"aps":{
"badge":1,
"alert":"This is my special message!",
"mycustomvar1":"123456",
"mycustomvar2":"some text",
"myspecialtext":"This is the best!",
"url":"http://www.mywebsite.com"
}
}
I am using code to check if a word is in my array, if it is I want it to submit it and I have the code for it. If it isn't I want it to pop up a screen. now this all works, the only thing is the screen pops up 2 times, because there are 2 words in my array. here is the code to explain it a little better.
NSArray *searchContacts = [NSArray arrayWithObjects:
#"CADEAU",
#"KADERZ",nil];
NSString *myContact = labelsText.text;
for (NSString *contact in searchContacts) {
if ([contact isEqualToString:myContact]) {
this is where I put in my words, CADEAU & KADERZ in this case. When I put one of these words into labelsText.text it does exactly what I want. but for the else statement if the labels text.text word is not CADEAU or KADERZ, it pop ups a screen:
else {
UIAlertView *alert = [[UIAlertView alloc]
This screen will pup up 2 times now, so i'll have to press dismiss 2 times, how would I fix this to just have to press dismiss one time no mather how many words are in the array?
It would be more efficient to use an NSSet, but even if you use an NSArray, you can simply call containsObject: instead of looping through the collection yourself.
if (![searchContacts containsObject:myContact]) {
//show alert...
}
Put a break; after the code showing your alert:
for (NSString *contact in searchContacts) {
if ([contact isEqualToString:myContact]) {
// do something
} else {
// show screen
break;
}
}
This will 'break' out of the loop.
I think you want something like this:
BOOL contactFound = NO;
for (NSString *contact in array)
{
if ([contact isEqualToString:myContact])
{
contactFound = YES;
break;
}
}
if (!contactFound)
UIAlertView *alert = [[UIAlertView alloc]...
Use a break after your UIAlertView.
For example:
for (NSString *contact in searchContacts) {
if ([contact isEqualToString:myContact]) {
//do what you want to do
}
else{
UIAlertView *alert = [[UIAlertView alloc] init];
[alert show];
break; //leave for()
}
}
Or use that:
searchContacts enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
if ([contact isEqualToString:myContact]) {
//do what you want to do
}
else{
UIAlertView *alert = [[UIAlertView alloc] init];
[alert show];
*stop = YES; //stop enumeration
}
}
I'm currently working in Xcode on an iOS app...
I've set up a UIAlertView (with a question as the message ) to pop up with a text field to retrieve a response.
The desired functionality is that upon entering an incorrect value into the text field, the UIAlert would loop... Until the correct response is entered. At this point, the UIAlert would be dismissed.
Heres what I have so far...
- (void)application:(UIApplication *)application
didReceiveLocalNotification:(UILocalNotification *)notification {
NSString* correctAnswer = #"2";
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:#"Alarm"
message:#"1 + 1 ="
delegate:self
cancelButtonTitle: nil
otherButtonTitles:#"Continue", nil ];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
UITextField* answerField = [alert textFieldAtIndex:0];
answerField.keyboardType = UIKeyboardTypeNumberPad;
answerField.placeholder = #"answer";
[alert show];
// I feel like this would work, but I know it doesn't...
NSString *answerFieldString = answerField.text;
if ([answerFieldString isEqualToString: correctAnswer ])
{
[alert dismissWithClickedButtonIndex:-1 animated:YES];
}
}
I've done extensive google searching and can't come up with a solution... Any responses would be much appreciated!
try this...
- (BOOL)alertViewShouldEnableFirstOtherButton:(UIAlertView *)alertView
{
NSString *answerFieldString = answerField.text;
if ([answerFieldString isEqualToString: correctAnswer ])
{
[alertView dismissWithClickedButtonIndex:-1 animated:YES];
}
}
I'm sick of writing basic UIAlertView's, ie:
UIAlertView *alert = [[UIAlertView alloc] initWith...]] //etc
Instead of doing this, is it possible to put all this in a "helper" function, where I can return the buttonIndex, or whatever an alert usually returns?
For a simple helper function I guess you could feed parameters for the title, message, I'm not sure whether you can pass delegates in a parameter though, or bundle info.
In pseudo-code, it could be like this:
someValueOrObject = Print_Alert(Title="", Message="", Delegate="", Bundle="") // etc
Any help on this would be great.
Thanks
In 4.0+ you can simplify the alert code using blocks, a bit like this:
CCAlertView *alert = [[CCAlertView alloc]
initWithTitle:#"Test Alert"
message:#"See if the thing works."];
[alert addButtonWithTitle:#"Foo" block:^{ NSLog(#"Foo"); }];
[alert addButtonWithTitle:#"Bar" block:^{ NSLog(#"Bar"); }];
[alert addButtonWithTitle:#"Cancel" block:NULL];
[alert show];
See Lambda Alert on GitHub.
This is what I wrote, when I got sick of doing the same:
-(void)alert:(NSString *)title withBody:(NSString *)message firstButtonNamed:(NSString *)firstButtonName {
[self alert: title withBody: message firstButtonNamed: firstButtonName withExtraButtons: nil informing: nil];
}
-(void)alert:(NSString *)title withBody:(NSString *)message firstButtonNamed:(NSString *)firstButtonName informing:(id)delegate {
[self alert: title withBody: message firstButtonNamed: firstButtonName withExtraButtons: nil informing: delegate];
}
-(void)alert:(NSString *)title withBody:(NSString *)message firstButtonNamed:(NSString *)firstButtonName withExtraButtons:(NSArray *)otherButtonTitles informing:(id)delegate {
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle: title
message: message
delegate: delegate
cancelButtonTitle: firstButtonName
otherButtonTitles: nil];
if (otherButtonTitles != nil) {
for (int i = 0; i < [otherButtonTitles count]; i++) {
[alert addButtonWithTitle: (NSString *)[otherButtonTitles objectAtIndex: i]];
}
}
[alert show];
[alert release];
}
You can't write a function that will display an alert and then return a value like a buttonIndex though, because that value-returning only occurs when the user presses a button and your delegate does something.
In other words, the process of asking a question with the UIAlertView is an asynchronous one.
