I am giving an UIImageView in the UIAlertView's accessoryView by the following code:
UIAlertView *alertView = [[UIAlertView alloc]init];
[alertView addButtonWithTitle:#"Cancel"];
[alertView addButtonWithTitle:#"OK"];
UIImageView *someImageView = /*initialization code */;
[someImageView setFrame:CGRectMake(0,0,40 ,20)];
[alertView someImageView forKey:#"accessoryView"];
[alertView show];
The above code works fine with iOS7 but since the update to iOS8 the alertView looks elongated and disoriented. I have tried changing the constraints and the aspect ratio of the image that is set in the UIImageView.
Can someone help me with this?
This is not a supported use of UIAlertView:
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.
Additionally, UIAlertView is deprecated in iOS 8.
You should build your own view to present, or use one of the many open-sourced options on GitHub/CocoaControls, like SDCAlertView or ios-custom-alertview.

The related code below worked perfect when i was building for iOS 7, but it seems now in iOS 8, it's not working properly.
By properly, I mean in the sense where it's not actually sending the file or whatever to the chosen app.
Example: If I selected Mail, it would open the mail app with the image or zip I chose in the text field. Now it won't send and it takes forever to call/dismiss the UIDocumentInteractionController.
What am I doing wrong?
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[self.tableView deselectRowAtIndexPath:indexPath animated:NO];
NSString *fileName = [directoryContents objectAtIndex:indexPath.row];
NSString *path;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
path = [[paths objectAtIndex:0] stringByAppendingPathComponent:#"Downloads"];
path = [path stringByAppendingPathComponent:fileName];
documentController = [[UIDocumentInteractionController alloc] init];
documentController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:path]];
[documentController setDelegate:self];
[documentController presentOptionsMenuFromRect:CGRectZero inView:self.view animated:YES];
[documentController retain];
}
I have been playing around with the UIDocumentInteractionController and Delegate trying to fix a similar problem, the controller opened-up alright but selecting an application caused it to close without doing anything, my delegate method documentInteractionControllerDidDismissOpenInMenu also run alright afterwards.
In the console i got the notification enabledRemoteNotificationTypes is not supported in iOS 8.0 and later.
It turns out that this problem will accrue when one of these delegate methods is called :
documentInteractionControllerDidDismissOpenInMenu
documentInteractionControllerDidDismissOptionsMenu
(and possibly others, i did not check all of them)
I did not find any comment in the IOS Development Library or the UIDocumentInteractionController.h about these methods not supported for IOS 8.1 but at this point i cant find any other explanation.
Solution :
i replaced documentInteractionControllerDidDismissOpenInMenu
with didEndSendingToApplication
and it solved the problem for me.
OK, I have an app that runs a timer. If the user is watching the app's timer count down (e.g. the app is awake and active in the foreground) I want an alert to be shown to the user. I've added this code to my timer when it reaches 0:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Reminder" message:#"It's time!" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
The problem I'm having is that if I put the phone to sleep or make the app inactive in some other fashion I have a local notification setup to handle this alerting so when the user goes back to the app I don't want them to see the alert mentioned above. It's an unnecessary "click" they have to make.
Is there a way to auto dismiss this alert when the app either goes into the background or enters the foreground if it's been triggered?
You have to use NSNotificationcenter at the UIAlertview definition.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:message delegate:nil cancelButtonTitle:nil otherButtonTitles:#"OK",nil];
[alert show];
[[NSNotificationCenter defaultCenter] addObserverForName:UIApplicationWillResignActiveNotification object:nil queue:[NSOperationQueue mainQueue] usingBlock:^(NSNotification* notification){
[alert dismissWithClickedButtonIndex:0 animated:NO];
}];
There is no auto dismiss.
You have to communicate that your app become active (from UIApplicationDelegate) to your UIAlertView.
To do so, many techniques exists, you could keep reference of that alert in AppDelegate to dismiss it, or use some NSNotification posted from delegate and observed in your ViewController or anywhere you are showing this alert.
Alternatively you could use... https://github.com/sdarlington/WSLViewAutoDismiss
Please forgive me is this is too vague. I have an app that has populated arrays based on where the user browses to. One is just all sites visited and is accessible in another viewcontroller and another is all text input in to the textview which is displayed while the user types. I don't know if any of that is important but my question is, I would like to have a settings page that has the option to clear that data. I can do it from the header file in that view its self but not sure how to send the removeallobjects command to other views or arrays.
In each view I have a button to call this:
-(IBAction)clearPreText {
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:#"clear all predictive typing?"
message:#"press ok to clear"
delegate: self
cancelButtonTitle:#"cancel"
otherButtonTitles:#"ok", nil];
[alert show];
}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 1) {
[pastUrls removeAllObjects];
[[NSUserDefaults standardUserDefaults] setObject:autocompleteUrls forKey:#"PastUrls"];
[self.autocompleteTableView reloadData];
}}
I would like to place those buttons in a new view, a settings page.
Thanks for anything.
Both controllers will have access to the app delegate and the app delegate will have access to each of your controllers. When I need to do something like this, I usually do it through the app delegate.
Hi I have a splitview app that is working fine until I add a TabBar in the rootview section. The problem is that when I add the TabBar to the rootview the app does not rotate to landscape, if I change the orientation the view remains in portrait mode.
How can I solve this?. Hope you can help

The answer below is correct. If you are adding tabs which include using the CoreDataTableView controller (that is used with the CS193P course), be sure to add a method to allow for any orientation. If not, your split view will not work correctly.
SOLVED:
I had the same issue.
Without the TabBar all is well, add the TabBar and the rotation breaks.
I guessed that there is something broken in the responder chain or view hierarchy.
So I was about to submit as a bug. So wrote a test app to demo to Apple (because they ALWAYS ask for one), and it worked. Hooray, but why?
These are my findings from the Apple docs.
From the View Programming Guide for iOS.
Split View Controller
"A split view controller must always be the root of any interface you create."
Thus they should not be embedded within a TabBar View, although I understand that there is a workaround out in the wild.
Also:
Creating a Tab Bar Interface
"Install it as one of the two root views in a split view interface. (iPad only)"
Solution:
After much more investigation, and some trial and error, I found the issue.
Of course it seems so obvious NOW.
When the SplitView tests for shouldAutorotateToInterfaceOrientation, it tests every possible view on the whole hierarchy, that is EVERY view in the MasterView, thus EVERY view in the TabBar, and EVERY view in the DetailView, thus EVERY view in the current NavigationStack.
The fly in the ointment is that a newly created ViewController does not support Landscape by default.
Where I had gone wrong was: I had created ALL of the TabBar subviews, but not written any more code yet, because I wanted to get the SplitView with TabBar working first, thus 1 of my Tab Views had not been changed from the default.
A buddy of mine asked for a quick sample of code for an app skeleton that would use a TableView to call a TabView. I estimated an hour.
After more hours than I want to admit messing around in IB, I gave up and implemented the following code.
Can anyone tell me how to do this in IB? I was careful (I thought) to make all the right connections, but no go. I even had another (working) app where I went through and step-by-step made the same connections. I got errors about "Changing the delegate of a tab bar managed by a tab bar controller is not allowed..." (This when I connected the TabBar's delegate to the File's owner, even though another app was working fine with that setting)
Until I wrote this code, I never got the tabbar view, only the view that came with the view xib... (I tested by putting a label on the view).
Thanks in advance...
UITabBarController *tabBarController = [[[UITabBarController alloc] initWithNibName:nil bundle:nil] autorelease];
NumberOneViewController *numberOneViewController = [[[NumberOneViewController alloc] initWithNibName:#"NumberOneViewController" bundle:nil] autorelease];
NumberTwoViewController *numberTwoViewController = [[[NumberTwoViewController alloc] initWithNibName:#"NumberTwoViewController" bundle:nil] autorelease];
NumberThreeViewController *numberThreeViewController = [[[NumberThreeViewController alloc] initWithNibName:#"NumberThreeViewController" bundle:nil] autorelease];
NumberFourViewController *numberFourViewController = [[[NumberFourViewController alloc] initWithNibName:#"NumberFourViewController" bundle:nil] autorelease];
tabBarController.viewControllers = [NSArray arrayWithObjects:numberOneViewController, numberTwoViewController,
numberThreeViewController, numberFourViewController, nil];
[self.navigationController pushViewController:tabBarController animated:YES];
self.view = tabBarController.view; in the viewDidLoad method of the TabBarController delegate class fixed it...
Ah well, surely someone else will run into the same thing and hopefully this will help them...
