I'm trying to use UIActivityViewController to share an image from my app. This is the source code:
UIImage *sourceImage = [[UIImage alloc] initWithContentsOfFile:[[self currentMedia] path]];
NSArray *activityItems = #[sourceImage];
UIActivityViewController *avc = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
avc.excludedActivityTypes = [NSArray arrayWithObjects:UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeAssignToContact, UIActivityTypeSaveToCameraRoll, nil];
[self presentViewController:avc animated:YES completion:nil];
[avc release];
[sourceImage release];
Everything works fine except for one issue: I don't see service names (Email, Twitter, Facebook etc) in the service picker. Look at the screenshot below:
Am I doing something wrong?
I am using ARC and don't have such problem. As far as UIActivityViewController is hardly rely on multithreading and blocks it is possible to affect some objects lifetime. So I would try to switch to ARC as recommends Apple or at least to make retained class property for UIActivityViewController.
If you pass nil for the activity types and you specify excluded types, nothing will show up.
However if you just pass nil for the first parameter, all the available built-in service types will show up.
I'm still having a bit of trouble getting this API to behave as I want it to, but that's one thing I did find.
You can use UIActivity class for this purpose. Activity objects are used in conjunction with a UIActivityViewController object, which is responsible for presenting services to the user.
look into activityTitle method of UIActivity class it returns string that describes the service.
Here is Example project.
Hope it helps you.

i want to share app info on social network with all social networking application that are previously installed in device. i have one demo images just like this, if any idea please give me.
Thanks in advance
Using UIActivityViewController you can Share, apple doc
Example:
UIImage *anImage = [UIImage imageNamed:#"SampleImg.png"];
NSArray *Items = [NSArray arrayWithObjects:
#"your app info",
anImage, nil];
UIActivityViewController *ActivityView =
[[UIActivityViewController alloc]
initWithActivityItems:Items applicationActivities:nil];
[self presentViewController:ActivityView animated:YES completion:nil];
Here’s a UI control called REActivityViewController from Roman Efimov that looks like a UIActivity view, but allows for full color icons, total customization, and the control works with iOS 5.0. The control looks and works as expected on iPhone and iPad.
This is not simply a control that looks like UIActivityController, but also makes it much easier to create custom activities.
Here’s an example from the readme showing how easy it is to create a custom activity controller:
REActivity *customActivity = [[REActivity alloc] initWithTitle:#"Custom"
image:[UIImage
imageNamed:#"REActivityViewController.bundle/Icon_Custom"]
actionBlock:^(REActivity *activity, REActivityViewController *activityViewController){
{
[activityViewController dismissViewControllerAnimated:YES completion:^{NSLog(#"Hey, there!");}
];
}];
Try this.Happy coding.
Posted this on Apple with no luck, but now that the iOS 6 NDA is up, hoping more eyes will see it here.
I am attempting to modify an app to only allow a user to select music that has been downloaded locally. I have the following code under iOS 6 GM:
MPMediaPickerController* mpc = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeAnyAudio];
mpc.allowsPickingMultipleItems = YES;
mpc.modalPresentationStyle = UIModalPresentationCurrentContext;
mpc.showsCloudItems = NO;
[self presentViewController:mpc animated:YES completion:nil];
From the documentation:
The default behavior for a media item picker is YES, which means the
the picker shows available iCloud items. A media item is considered an
iCloud item if it is available via iTunes Match and is not already
stored on the device.
I take this to mean that if iTunes Match is enabled, only items that have been downloaded to the device will show in the picker, however I always see the entire iTunes Match library. I filed a radar for this, because it seems like a serious bug. If anyone can tell me otherwise, I'd love to know what I'm missing here.
This seems to be an OS problem.
Using picker.showsCloudItems = NO; correctly shows fewer songs, instead of the whole list... The songs listed there are songs that either were manually downloaded in the Music app or songs that were streamed and therefore cached.
The problem, at least in my case, is dealing with the cached ones.
If I select a song that was manually downloaded the value of MPMediaItemPropertyIsCloudItem is NO, which is correct. I can also access the asset's URL through the MPMediaItemPropertyAssetURL property.
On the other hand, selecting a song that was cached returns YES on MPMediaItemPropertyIsCloudItem and nil on MPMediaItemPropertyAssetURL, making the song virtually useless to me.
Sorry I don't have an actual answer but I don't have enough reputation to simply comment.
Hope my 2 cents help somehow, but it truly seems to me that this issue can only be resolved by Apple in a future update.
A better solution to test if an item comes from iCloud in the didPickMediaItems delegate:
MPMediaItem *selectedItem = [selectedItems objectAtIndex:0];
if (![[selectedItem valueForProperty:MPMediaItemPropertyIsCloudItem] boolValue])
You don't really need to play it, it is more efficient to use the embedded property in the MPMediaItem.
I had this same problem. Although I was unable to hide the items, here's a good workaround that I used to prevent people from being able to select them. Inside didPickMediaItems, you should temporarily load it into an AVPlayerItem and then just check the validity of that item like so:
- (void)mediaPicker:(MPMediaPickerController *)mediaPicker didPickMediaItems:(MPMediaItemCollection *)mediaItemCollection
{
MPMediaItem *selectedItem = [[mediaItemCollection items]objectAtIndex:0];
NSURL *tempURL = [selectedItem valueForProperty:MPMediaItemPropertyAssetURL];
AVPlayerItem *playerItem = [[AVPlayerItem alloc]initWithURL:tempURL];
if(playerItem.loadedTimeRanges==NULL)
{
UIAlertView *alert=[[[UIAlertView alloc]initWithTitle:NSLocalizedString(#"Invalid Song Choice",NULL) message:NSLocalizedString(#"Please choose a song that is local to your phone.",NULL) delegate:self cancelButtonTitle:NSLocalizedString(#"Okay",NULL) otherButtonTitles:nil]autorelease];
[alert show];
[playerItem release];
}
else
{
NSLog(#"Your good to go...do whatever you want with the local song");
}
}
It appears to be fixed in iOS 7.
The following code works; iCloud items are not showing:
MPMediaPickerController *picker = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeMusic];
picker.delegate = self;
picker.allowsPickingMultipleItems = NO;
picker.showsCloudItems = NO;
How to add Event in iPhone Calendar. I just want to add events in iPhone calendar using my application and wants to set pushnotification for perticuler event. Please help me out on this. Thank you.
To create an Event programmatically, you would use EventKit, more specifically the provided EKEventEditViewController. See the Apple documentation for an explanation and sample code.
In iOS 4.0+, you would also be able to access that controller without writing any EventKit code. To do that, use a UITextView configured with dataDetectorTypes = UIDataDetectorTypeCalendarEvent. The UITextView will automatically convert strings representing formatted dates, days of the week, etc. - to clickable URLs that handle the creation of events.
Please refer to the Apple iOS documentation for the rest of your question. If there is anything specific that doesn't work in your case, please post some code, show us what you have tried already, etc.
you can use this code
EKEventStore *es = [[EKEventStore alloc] init];
EKEventEditViewController *controller = [[EKEventEditViewController alloc] init];
controller.eventStore = es;
controller.editViewDelegate = self;
[self presentModalViewController:controller animated:YES];
[controller release];
I have implemented a basic add contact feature to an iOS 4 application. Following the documentation from Apple, I have created a navigation controller, and set its root view to the ABNewPersonViewController. I have implemented the delegate as well. The basic mechanics all work.
The problem I am having is when you add a photo to the new person that is very large (taking a photo or picking one from the library), the ABNewPersonViewController form returns empty when the camera controls are dismissed. No photo is in the add photo box either. If I pick a small image (say a screenshot from the iPhone), everything works. I can see from the debug output: Received memory warning. Level=1
Has anyone else run into this? Is there a way to set the photo quality to a lower setting for the ABNewPersonViewController? Any help appreciated.
ABNewPersonViewController *abNewPersonView = [[ABNewPersonViewController alloc] init];
abNewPersonView.newPersonViewDelegate = self;
UINavigationController *newNavigationController = [UINavigationController alloc];
[newNavigationController initWithRootViewController:abNewPersonView];
[self presentModalViewController:newNavigationController animated:YES];
[abNewPersonView release];
[newNavigationController release];
If ABNewPersonViewController does not handle memory warnings correctly, file a bug with apple.
I'm playing around with this application I got on last months Web Designer that's a very basic RSS reader. I would like to add a refresh button to the top navigation bar that refreshes all the content in the table but can't seem to work out how to do it. I've worked out it must somehow use the [tablename Reload] function, but have got no idea how to implement it.
I'm new to all this so simple instructions are good instructions :) I know how to add the button, its linking it to and defining the actions when the user clicks it that I'm struggling with.
You can grab the code here http://www.webdesignermag.co.uk/tutorial-files/issue-162-tutorial-files/ under iPhone Apps (it's the only one).
This is what you need to do in the RootViewController.m:
In the viewDidLoad function, add a button of type UIBarButtonSystemItemRefresh, associate to it an Action and a Target, (infact, as Alan told you, you need to learn about Outlets and Actions)
UIBarButtonItem *refreshButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:#selector(refreshTable)];
self.navigationItem.rightBarButtonItem = refreshButton;
Implement refreshTable function (if not declared in .h, have to put it above viewDidLoad())
- (void)refreshTable{
[rssParser release];
rssParser = [[RSSXMLParser alloc] init];
[rssParser parseRSSFeed];
[self.tableView reloadData];
NSLog(#"table is refreshing ....");
}
Hi Graeme and velcome to SO.
For the iphone UI, you have to define outlets and actions, and use Interface Builder to link them together.
This page has some information that should hopefully get you started.
