In my app I sent a request to my PHP file to download some info. Whenever I use the code below it will terminate:
-(void)downloadItems
{
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
NSString *myString = [prefs stringForKey:#"commentsId"];
NSLog(#"The comments id is : %#",myString);
// Download the json file
NSString *urlstring = [NSString stringWithFormat:#"http:/MyWebSite.com/checkphp.php?title=%#", myString];
NSURL *jsonFileUrl = [NSURL URLWithString:urlstring];
NSLog(#"The qasida id is: %#", jsonFileUrl);
// Create the request
NSURLRequest *urlRequest = [[NSURLRequest alloc] initWithURL:jsonFileUrl];
// Create the NSURLConnection
[NSURLConnection connectionWithRequest:urlRequest delegate:self];
}
But if I remove myString from urlString like this:
NSURL *jsonFileUrl = [NSURL URLWithString:#"http:/myWebSite/checkphp.php?title=%#"];
the app will not terminate and it will retrieve data.
Can any one tell me what is wrong with my code?
Thanks

In my app for Mac I use the NSSharingServicePicker for mailing some items. My problem is that I want to set the default email address to be sent. How can I set this value to show it when the mail client opens??
I have this code:
NSMutableArray *shareItems = [NSMutableArray arrayWithObject:#"MyText"];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fileName = [NSString stringWithFormat:#"%#/MyFile.pdf", documentsDirectory];
NSURL* tempFileURL = [NSURL fileURLWithPath:fileName];
[shareItems addObject:tempFileURL];
NSSharingServicePicker *sharingPicker = [[NSSharingServicePicker alloc] initWithItems:shareItems];
sharingPicker.delegate = self;
This is what I want. I need to set the default destination address in the email.
Sorry for my poor english. Thanks in advance.
SOLVED:
-(id<NSSharingServiceDelegate>)sharingServicePicker:(NSSharingServicePicker *)sharingServicePicker delegateForSharingService:(NSSharingService *)sharingService
{
[sharingService setRecipients:#[#"email#email.com"]];
[sharingService setSubject:#"MySubject"];
return self;
}
NSSharingServiceNameComposeEmail is generally the standard way to achieve this:
NSSharingService *service = [NSSharingService sharingServiceNamed:NSSharingServiceNameComposeEmail];
service.delegate = self;
service.recipients = #[#"tim.cook#apple.com"];
service.subject = [ NSString stringWithFormat:#"%#",NSLocalizedString(#"Re: Requested PDF",nil)];
[service performWithItems:shareItems];
It's not exactly clear what you are doing with NSSharingServicePicker, although this code can be used with shareItems, so the file would be attached along with the body text.
I have an iPad that has a routine to create a pdf and send as an attachment to an email. It all seems to work with the email composer opening showing the pdf document attached. However when tested on an iPad, when the email is received there is no attachment. Any ideas?
[mailComposer addAttachmentData:data mimeType:#"application/pdf" fileName:#"pdffile.pdf"];
[self presentViewController:mailComposer animated:YES completion:nil];
Many thanks
Detail:
The pdf file is created and called pdffile.pdf. The following is the full email routine:
MFMailComposeViewController *mailComposer;
mailComposer = [[MFMailComposeViewController alloc] init];
mailComposer.mailComposeDelegate = self;
[mailComposer setModalPresentationStyle:UIModalPresentationFormSheet];
[mailComposer setSubject:[NSString stringWithFormat: #"i-observe Lesson Observation for: %s", "date"]];
[mailComposer setMessageBody:[NSString stringWithFormat: #"i-observe Lesson Observation for: %s", "name"] isHTML:NO];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *file = [documentsDirectory stringByAppendingFormat:#"pdffile.pdf"];
NSMutableData *data=[NSMutableData dataWithContentsOfFile:file];
[mailComposer addAttachmentData:data mimeType:#"application/pdf" fileName:#"pdffile.pdf"];
[self presentViewController:mailComposer animated:YES completion:nil];
Try This Method:
if([MFMailComposeViewController canSendMail]){
MFMailComposeViewController *mail=[[MFMailComposeViewController alloc]init];
mail.mailComposeDelegate=self;
[mail setSubject:#"Email with attached pdf"];
NSString *newFilePath = #"get path where the pdf reside";
NSData * pdfData = [NSData dataWithContentsOfFile:newFilePath];
[mail addAttachmentData:pdfData mimeType:#"application/pdf" fileName:#"yourpdfname.pdf"];
NSString * body = #"";
[mail setMessageBody:body isHTML:NO];
[self presentModalViewController:mail animated:YES];
[mail release];
}
else
{
NSLog(#"Message cannot be sent");
}
The next solutions is based assuming that the pdf file is in your main bundle:
NSBundle *mainBundle = [NSBundle mainBundle];
NSString *myFile = [mainBundle pathForResource: #"RealNameofFile" ofType: #"pdf"];
NSData *pdfD = [NSData dataWithContentsOfFile:myFile];
[mailViewController addAttachmentData:pdfData mimeType:#"application/pdf" fileName:#"Nametodisplayattached.pdf"];
make sure that the file has the same name as the table cell
I have a Mac application that is supposed to fetch Twitter followers and friends for a given username and then, in turn, ask Twitter for the user NAMES for each of those returned UserIDs. As you can see below, I have a method that will call the Twitter API to get friends/followers (which works fine). It is the userNameForUserID:delegate: method that is causing me problems. I used to do these requests synchronously and return the NSString for the username right then. That (now commented out) line always broke, so I tried doing it with an NSURLConnection asynchronously. Still doesn't work. I don't understand why
[[NSString alloc] initWithContentsOfURL:...] works for the fetchFollowers... method, but not when I do it the EXACT SAME way in the other...
I put a break point on the line that used to alloc init the NSString with contents of URL, and when I step into it, it doesn't break, return, throw an exception, crash...nothing. It's as if that line just got stepped over (but my application is still blocked.
Any ideas? Much appreciated!
NSString * const GET_FOLLOWERS = #"https://api.twitter.com/1/followers/ids.json?cursor=-1&screen_name=";
NSString * const GET_FRIENDS = #"https://api.twitter.com/1/friends/ids.json?cursor=-1&screen_name=";
NSString * const GET_USER_INFO = #"https://api.twitter.com/1/users/show.json?user_id=";
#implementation TwitterAPI
+ (void)userNameForUserID:(NSNumber *)userID delegate:(id<UserNameDelegate>)delegate
{
NSURL *url = [NSURL URLWithString:[GET_USER_INFO stringByAppendingString:[userID stringValue]]];
// NSString *JSON = [[NSString alloc] initWithContentsOfURL:url encoding:NSUTF8StringEncoding error:&error];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[NSURLConnection sendAsynchronousRequest:req queue:queue completionHandler:^(NSURLResponse *urlResponse, NSData *data, NSError *error) {
[delegate addUserNameToArray:data];
}];
}
+ (NSArray *)fetchFollowersWithUserName:(NSString *)userName
{
NSURL *url = [NSURL URLWithString:[GET_FOLLOWERS stringByAppendingString:userName]];
NSArray *followerIDs;
NSString *JSON = [[NSString alloc] initWithContentsOfURL:url encoding:NSASCIIStringEncoding error:nil];
if ([JSON rangeOfString:#"error"].location == NSNotFound)
followerIDs = [[JSON JSONValue] valueForKey:#"ids"];
return followerIDs;
}
I have two local .html files in the Resources folder. I'm trying to load them the following way, but only the final page loads. What am I doing wrong?
File = please_wait.html
This one does not work.
NSError *error;
NSString* path = [[NSBundle mainBundle] pathForResource:#"please_wait" ofType:#"html"];
NSString* htmlString = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:&error];
[webView loadHTMLString:htmlString baseURL:[NSURL fileURLWithPath:path]];
//Big "do-while" loop here. It works fine so I omitted it.
File = update_graph.html
This one does not work
path = [[NSBundle mainBundle] pathForResource:#"update_graph" ofType:#"html"];
htmlString = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:&error];
[webView loadHTMLString:htmlString baseURL:[NSURL fileURLWithPath:path]];
//Lots of code removed. All works correctly and doesn't touch webview
This last one works perfectly. Google displays.
string = #"http://google.com";
NSURL *url = [NSURL URLWithString: string];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];
It appears from your comment that your UIWebView loads just fine, but it does not get a chance to refresh itself on the screen until you exit your method. It is not enough to set a break point inside the method and wait for the view to load: you must exit the method before iOS realizes that it needs to call UIWebView's drawRect method.
To fix this, split your method in three parts, A B and C, and set UIWebView's delegate in A to invoke B on webViewDidFinishLoad:, and the delegate in B to call C.
Here is how to implement this: start with a delegate that can call a selector when the loading has completed:
#interface GoToNext : NSObject <UIWebViewDelegate> {
id __weak target;
SEL next;
}
-(id)initWithTarget:(id)target andNext:(SEL)next;
-(void)webViewDidFinishLoad:(UIWebView *)webView;
#end
#implementation GoNext
-(id)initWithTarget:(id)_target andNext:(SEL)_next {
self = [super init];
if (self) {
target = _target;
next = _next;
}
return self;
}
-(void)webViewDidFinishLoad:(UIWebView *)webView {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Warc-performSelector-leaks"
[target performSelector:next];
#pragma clang diagnostic pop
}
#end
Now split your method into three parts - loading the first page, loading the second page, and loading the third page:
-(void)loadPleaseWait {
NSError *error;
NSString* path = [[NSBundle mainBundle] pathForResource:#"please_wait" ofType:#"html"];
NSString* htmlString = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:&error];
webView.delegate = [[GoToNext alloc] initWithTarget:self andNext:#selector(loadUpdateGraph)];
[webView loadHTMLString:htmlString baseURL:[NSURL fileURLWithPath:path]];
// big do-while loop
}
-(void)loadUpdateGraph {
NSError *error;
NSString* path = [[NSBundle mainBundle] pathForResource:#"update_graph" ofType:#"html"];
NSString* htmlString = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:&error];
webView.delegate = [[GoToNext alloc] initWithTarget:self andNext:#selector(loadGoogle)];
[webView loadHTMLString:htmlString baseURL:[NSURL fileURLWithPath:path]];
// Lots of code removed
}
-(void)loadGoogle {
string = #"http://google.com";
NSURL *url = [NSURL URLWithString: string];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];
}
