ShareKit email form not always displaying - objective-c

I'm using ShareKit to share objects to Twitter, Facebook, and Email. Twitter and Facebook works fine, but email doesn't. And I don't really know why.
It seems like it works quite randomly.
I set it up like this:
[self.customView.shareButton addTarget:self action:#selector(sharePost:) forControlEvents:UIControlEventTouchUpInside];
- (void)sharePost:(UIButton *)sender
{
NSURL *url = [NSURL URLWithString:self.currentPost.link];
// Add image.
NSString *imageUrlString = [NSString stringWithFormat:[link]];
NSURL *imageUrl = [NSURL URLWithString:imageUrlString];
UIImageView *postImage = [[UIImageView alloc] init];
[postImage setImageWithURL:imageUrl];
SHKItem *item = [SHKItem image:postImage.image title:[NSString stringWithFormat:#"%#", self.currentPost.title]];
[item setURL:url];
[item setMailBody:[NSString stringWithFormat:#"%# %#", self.currentPost.title, self.currentPost.link]];
// Get the ShareKit action sheet
// This works
SHKActionSheet *actionSheet = [SHKActionSheet actionSheetForItem:item];
// ShareKit detects top view controller (the one intended to present ShareKit UI) automatically,
// but sometimes it may not find one. To be safe, set it explicitly.
[SHK setRootViewController:self];
// Display the action sheet.
[actionSheet showInView:self.view];
}
Any ideas or what I'm missing or doing wrong?

Try to change the RootViewController and view you are using:
[SHK setRootViewController:self.view.window.rootViewController];
[actionSheet showInView:self.view.window.rootViewController.view];
Most likely your view controller hierarchy is somewhat messed up.

Objective-C MPMediaItem with null URL

I have a project that makes use of a MPMediaPickerController to select audio files from the Media Player. However, when trying to store it's URL, I am getting nothing but null returned. My code can be seen below:
- (void)showMediaPicker:(NSString *)title {
MPMediaPickerController *picker = [[MPMediaPickerController alloc] initWithMediaTypes:MPMediaTypeAny];
picker.delegate = self;
picker.prompt = title;
picker.allowsPickingMultipleItems = NO;
picker.showsCloudItems = NO;
[self.viewController presentViewController:picker animated:YES completion:NULL];
}
- (void)mediaPicker: (MPMediaPickerController *)mediaPicker didPickMediaItems:(MPMediaItemCollection *)mediaItemCollection {
MPMediaItem *item = [mediaItemCollection.items firstObject];
NSURL *assetURL = [item valueForProperty:MPMediaItemPropertyAssetURL];//returning null
NSString *type = [self contentTypeForFile:assetURL.lastPathComponent];
NSString *title = [item valueForProperty:MPMediaItemPropertyTitle];
[self callbackWithName:title type:type url:assetURL];
}
For whatever reason, my *assetURL is nil upon selecting a single audio item from the device's library. The only answers i could find with respect to this problem often relate to the url being null when a cloud item is selected from the MediaPicker. However, as seen above, I have set showCloudItems = NO.
I would greatly appreciate any help; let me know if you need any additional information!
Turns out, music from the "iCloud Music Library" is DRM protected and therefore, the assetURL is left null when selected in the MPMediaPickerController. The simple fix was to turn off the "iCloud Music Library" setting from within the settings for the "Music" app. I would expect picker.showsCloudItems = NO; to prevent this, but apparently I was mistaken.

How can I add 'Follow us on facebook' button to an iOS app?

I've about completed my iOS app but only need to add two buttons:
Follow us on facebook
Follow us on twitter
I assumed I would find a couple of simple examples here, but was surprised to find no answer to this at all (yet).
I'm pretty sure I could spend the next few hours trying to figure it out, but thought I'd reach out for a little time-saving help.
Just looking for the code to go behind a button on a view controller (XCode 4.5.1, iOS 6).
I assume the only variable I might need to supply is the company's facebook account name.
Any suggestions? (Thanks in advance!)
First, the URL schem for Facebook: fb://profile/<yourpageid> (source). A URL with this structure will open the Facebook app, if it is installed.
More on iOS URL schemes.
When your button is tapped, you can check if the Facebook is installed:
-(IBAction)fbButtonTap:(id)sender {
NSURL *fbURL = [[NSURL alloc] initWithString:#"fb://profile/<yourpageid>"];
// check if app is installed
if ( ! [[UIApplication sharedApplication] canOpenURL:fbURL] ) {
// if we get here, we can't open the FB app.
fbURL = ...; // direct URL on FB website to open in safari
}
[[UIApplication sharedApplication] openURL:fbURL];
}
For twitter, you follow the same basic steps. The Twitter URL scheme for iOS is twitter://user?id=12345 or twitter://user?screen_name=yourname (source). Again, if the Twitter app is not installed, you have open the twitter profile in safari.
As for taking direct actions, I do not think you can do that, since there is no inherent knowledge about any other applciation installed on the device. The best I think you can do is direct users to each respective account.
You could use SLRequest have someone follow you. This will only work on iOS 6 though, on iOS 5 Twitter works but not Facebook.
An example of SLRequest for someone to follow you on Twitter, make sure this is called on the background thread:
ACAccountStore *accountStore = [[ACAccountStore alloc] init];
ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
[accountStore requestAccessToAccountsWithType:accountType options:nil completion:^(BOOL granted, NSError *error) {
if (granted) {
// Get the list of Twitter accounts.
NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];
// For the sake of brevity, we'll assume there is only one Twitter account present.
// You would ideally ask the user which account they want to tweet from, if there is more than one Twitter account present.
if ([accountsArray count] > 0) {
// Grab the initial Twitter account to tweet from.
ACAccount *twitterAccount = [accountsArray objectAtIndex:0];
NSMutableDictionary *tempDict = [[NSMutableDictionary alloc] init];
[tempDict setValue:#"Your twitter name" forKey:#"screen_name"];
[tempDict setValue:#"true" forKey:#"follow"];
SLRequest *followRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodPOST URL:[NSURL URLWithString:#"https://api.twitter.com/1/friendships/create.json"] parameters:tempDict];
[followRequest setAccount:twitterAccount];
[followRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
NSString *output = [NSString stringWithFormat:#"HTTP response status: %i", [urlResponse statusCode]];
NSLog(#"%#", output);
if (error) {
dispatch_async(dispatch_get_main_queue(), ^{
//Update UI to show follow request failed
});
}
else {
dispatch_async(dispatch_get_main_queue(), ^{
//Update UI to show success
});
}
}];
}
}
}];
And for Facebook you just have to change some of it and look at their API and change the request URL.
this is my code for show people to like the community page of my app.
you can add the _webview where you want to show inside the code.
facebook gives the code for showing the page inside webview.
-(void)likeus
{
_webview =[[UIWebView alloc] initWithFrame:CGRectMake(14,94, 292, 250)];
AppDelegate *appdelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
//Load web view data
NSString *strWebsiteUlr =#"http://www.facebook.com/plugins/likebox.php?href=https%3A%2F%2Fwww.facebook.com%2Fenbuyukkim&width=292&height=258&show_faces=true&colorscheme=dark&stream=false&border_color&header=false&appId=433294056715040";
// Load URL
//Create a URL object.
NSURL *url = [NSURL URLWithString:strWebsiteUlr];
//URL Requst Object
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
//Load the request in the UIWebView.
[_webview loadRequest:requestObj];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:_webview
action:#selector(removeFromSuperView)
forControlEvents:UIControlEventTouchUpInside];
button.frame = CGRectMake(270.0, 80.0, 30.0, 30.0);
[button setBackgroundImage:[UIImage imageNamed:#"cross.png"] forState:UIControlStateNormal];
[_webview addSubview:button];
}
I am not sure if this is what you are looking for, but I think I found the solution, here at stack overflow on another thread.

iOs Custom scheme in MFMailComposeViewController

I'm trying to send via MFMailComposeViewController a custom url scheme so that the receipient could tap on the embedded link and open my application on his iphone.
So far the receipient gets an email but nothing happens when he taps on the LINK.
here is the code:
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self; // <- very important step if you want feedbacks on what the user did with your email sheet
[picker setSubject:#"Incoming task"];
// Fill out the email body text
NSString * types = #"";
for(NSString *type in task.location_types){
types = [types stringByAppendingFormat:#"%#|",type];
}
if(types.length > 1){
types = [types substringToIndex:types.length - 1];
}
NSString *desc = [task.description stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *link = [NSString stringWithFormat:#"helpy://?taskid=%d&desc=%#&types=%#\"",task.TaskId,desc,types];
NSString *emailBody = [NSString stringWithFormat:#"TAP HERE<script type=\"text/javascript\" charset=\"utf-8\">function doSomething() { window.location = \"%#\;return false;}</script>",link];
[picker setMessageBody:emailBody isHTML:YES];
picker.navigationBar.barStyle = UIBarStyleBlack;
[controller presentModalViewController:picker animated:YES];
[picker release];
helpy://?taskid=..... is my custom registered URL Scheme and if I type it from the address bar of the browser it opens up my application on the iPhone.
For some reason when this link is embedded into email, tapping it does not do anything.
Any help?
thanks
I highly doubt that Mail will execute JavaScript on iOS (even on the desktop I highly doubt it, but haven't tried it though). Simply set the URL as the href attribute of your hyperlink and everything should work fine. Any reason why you want to do it with JavaScript? I'm just curious ;-)
NSString *link = [NSString stringWithFormat:#"helpy://?taskid=%d&desc=%#&types=%#\"",task.TaskId,desc,types];
NSString *emailBody = [NSString stringWithFormat:#"TAP HERE", link];

Sharekit not populating facebook text box

Here is the code I use. I am able to see popup but I do not see the text pre-populated in the facebook popup.
Any suggestions?
- (IBAction) shareViaFacebook
{
[self prepareToShare];
// create the item to share
NSString *share = [NSString stringWithFormat:#"I'm tracking %# in some stuff, check it out! http://somewebsite.com/g/%d #TEST",
self.game.name,
[self.game.serverId intValue]];
SHKItem *item = [SHKItem text:share];
// share the item
[SHKFacebook shareItem:item];
}
On the same age, the following code for twitter works just fine. That is everything gets prepopulated
- (IBAction) shareViaTwitter
{
[self prepareToShare];
// create the item to share
NSString *share = [NSString stringWithFormat:#"I'm tracking %# in some stuff, check it out! http://somewebsite.com/g/%d #TEST",
self.game.name,
[self.game.serverId intValue]];
SHKItem *item = [SHKItem text:share];
// share the item
[SHKTwitter shareItem:item];
}
This is an example from my project using ShareKit:
NSString *finalPostedString = [[NSString alloc] initWithFormat:#"Check out this"];
SHKItem *item1= [SHKItem text:finalPostedString];
SHKActionSheet *actionSheet = [SHKActionSheet actionSheetForItem:item1];
[actionSheet showInView:self];
Try that out and hopefully it helps.
EDIT: Or more specifically, check this thread out that also should answer your question:
iPhone/iOS - How to use "ShareKit" to post only to Facebook or only to Twitter

Help on Objective C? My app keeps crashing?

I am creating an app for the Iphone/Itouch, but I keep on running into a couple of major leaks that just crash the app. In my game, right when I press play (from the home screen)It goes to another page that has the game on it. But, right after it appears, ind the console I get a Warning: Memory level=1. What could be happening? Here is my ViewDidLoad Method:
-(void)viewDidLoad {
[super viewDidLoad];
array = [[NSMutableArray alloc] initWithCapacity:100];
bulletArray = [[NSMutableArray alloc] initWithCapacity:100];
pos = CGPointMake(0.0,-5.0);
NSString *path = [[NSBundle mainBundle] pathForResource:#"GloriousMorning" ofType:#"mp3"];
AVAudioPlayer *theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
//float effects_Volume = [[NSUserDefaults standardUserDefaults] floatForKey:#"effectsVolume"];
//theAudio.volume = effects_Volume;
[theAudio play];
}
And also, a second question, since my game is a shooting game, the user presses a button titled "Fire". But, every time I test my app on a device, It crashes when I press the fire button. Here is my code for the fire button.
-(IBAction)Fire {
NSString *path = [[NSBundle mainBundle] pathForResource:#"gunShot" ofType:#"mp3"];
AVAudioPlayer *theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
//float effects_Volume = [[NSUserDefaults standardUserDefaults] floatForKey:#"effectsVolume"];
//theAudio.volume = effects_Volume;
[theAudio play];
//IBOutlet UIImageView *newBullet = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Bullet.png"]];
UIImageView *newBullet = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Bullet.png"]];
newBullet.frame = CGRectMake(0, 0, 10.0, 10.0);
newBullet.center = CGPointMake(239.0, 236.0);
[bulletArray addObject:newBullet];
[self.view addSubview:newBullet];
}
First, I create a sound. Then, I place a bullet right where the gun is currently located, and add it to an array so that every .01 of a second, in another bit of code, I can run through the array and check every bullet to detect collision.
Please tell me what I am doing wrong. Thanks!!!
The error when I click the Fire Button that makes the app crash is this:
GDB: Data Formatters temporarily unavailable, will retry after a 'continue'(unknown error loading shared library "
And Also I think I am making a huge leak when I try to play the audio, at least that's what someone told me. (If that is the case, please tell me how to fix it)
You alloc'd theAudio so you need to release it when you are done. Might be better to make that a ivar so you don't have to set up and tear down the audio every time they press the fire button.
