I could reproduce it in iOS 13.0 beta 4 with a sample app showing a UITextView with a special attributed string including a link. It crashes when tap-holding or dragging the link.
NSMutableAttributedString *aString = [[NSMutableAttributedString alloc] initWithString:#""];
NSTextAttachment *attachment = [[NSTextAttachment alloc] init];
attachment.image = [[UIImage imageNamed:#"weblink"] imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
attachment.bounds = CGRectMake(0, 0, 15, 15);
[aString appendAttributedString:[NSAttributedString attributedStringWithAttachment:attachment]];
[aString appendAttributedString:[[NSAttributedString alloc] initWithString:#" More Information"]];
[aString addAttribute:NSLinkAttributeName value:[NSURL URLWithString:#"https://www.apple.com"] range:NSMakeRange(0, aString.length)];
self.textView.attributedText = aString;
Filed on Feedback Assistant as FB6738178.
I had the same issue when use the method of UITextInput
replaceRange:(UITextRange *)range withText:(NSString *)text;
I cannot find the best solution, but I fix the crash by avoiding using special characters
'
in the 2nd parameter of replaceRange method
ps:the issue only occurred in iOS 11

I get this crash on iOS 7,
Assertion failed: (result == KERN_SUCCESS), function + [XPCMachSendRight wrapSendRight:], file /SourceCache/XPCObjects/XPCObjects-46/XPCMachSendRight.m, line27.
Steps which lead to this crash are,
Opening MFMailComposeViewController
Press home button
App crashed.
Here is crash report,

I found similar problem mentioned here: app get crashed while navigating to RootViewController from Message popup
Crash occurs rarely. I don't know what [XPCMachSendRight wrapSendRight:] this is and how to prevent it from crashing my app?
Before using MFMailComposeViewController class, you must always check to see if the current device is configured to send email at all using the canSendMail method. If the user’s device is not set up for the delivery of email, you can notify the user or simply disable the email dispatch features in your application. You should not attempt to use this interface if the canSendMail method returns NO.
Use this code....
if ([MFMailComposeViewController canSendMail])
{
MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
mailer.mailComposeDelegate = self;
[mailer setSubject:#"A Message from Bloomingkids"];
NSArray *toRecipients = [NSArray arrayWithObjects:#"support#bloomingkids.com", nil];
[mailer setToRecipients:toRecipients];
UIImage *myImage = [UIImage imageNamed:#"bloomingKidsLogo.png"];
NSData *imageData = UIImagePNGRepresentation(myImage);
[mailer addAttachmentData:imageData mimeType:#"image/png" fileName:#"Images"];
NSString *emailBody = #"Have you seen the Bloomingkids web site?";
[mailer setMessageBody:emailBody isHTML:NO];
[self presentViewController:mailer animated:YES completion:nil];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Failure"
message:#"Your device doesn't support the composer sheet"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles: nil];
[alert show];
}
Add any email account in your device first means setup an email account...
I have a UITableView that is successfully populated from a database, put into a NSArray and every cell is clickable and performs the correct action when selected, however the list is out of alphabetical order. In order to sort them into alphabetical order, I use the following code:
NSSortDescriptor *sort = [NSSortDescriptor sortDescriptorWithKey:#"Name" ascending:YES];
sortedArray = [buildings sortedArrayUsingDescriptors:[NSArray arrayWithObject:sort]];
The alphabetizing works correctly, however when some of the cells (in this example it was the first cell in the list) are clicked the app terminates with an uncaught exception:
'NSRangeException' '*** -[__NSArrayM objectAtIndex:]: index 1 beyond bounds [0 .. 0]'
I'd be happy to post more code excerpts, I am just unsure of what relevant information would be needed to help answer this question.
Edit:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSInteger r = [indexPath row];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
if(infoInst != nil) {
infoInst = nil;
}
infoInst = [[DirInfoListing alloc] initWithNibName:#"DirInfoListing" bundle:nil building:[self.listData objectAtIndex:r] map:mapUI];
NSLog(#"infoInst building: %#", [self.listData objectAtIndex:r]);
NSString *deviceType = [UIDevice currentDevice].model;
if([deviceType isEqualToString:#"iPad"] || [deviceType isEqualToString:#"iPad Simulator"]){
[self presentModalViewController:infoInst animated:YES];
} else {
[self.navigationController pushViewController:infoInst animated:YES];
}
}

Thank you!
The only array access I see in didSelectRowAtIndexPath is [self.listData objectAtIndex:r]. So it would seem your listData array isn't in sync with the table's data model. From the code you posted, the array sortedArray should correspond to the data model, so make sure listData and sortedArray are kept in sync or just have one array. If you still can't figure it out, please post your UITableViewDataSource methods as well as the methods where you set up your various array variables.
NSSortDescriptor *sort = [NSSortDescriptor sortDescriptorWithKey:#"Name" ascending:YES];
sortedArray = [buildings count] <= 1 ? buildings : [buildings sortedArrayUsingDescriptors:[NSArray arrayWithObject:sort]];
Unless you require sortedArray to be a different instance than buildings. Then you should change the statement accordingly.
Hey fellas, while running through a debugger I am seeing the following appear the second time it sets the variables (timestamp and checksum are set through this method one after the other, it works fine when no DataFeedManager exists, but upon returning to it again it crashes when it's time to set the checksum):
Here is the function of interest:
//sets specified attribute to the passed in value while ensuring that only one instance of the DataFeedManager exists
-(void)setItemInDFMWhilePreservingEntityUniquenessForItem:(attribute)attr withValue:(id)value {
SJLog(#"CoreDataSingleton.m setItemInDFMWhilePreservingEntityUniquenessForItem");
NSError *error;
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription
entityForName:#"DataFeedManager" inManagedObjectContext:[self managedObjectContext]];
[fetchRequest setEntity:entity];
NSUInteger numEntities = [[self managedObjectContext] countForFetchRequest:fetchRequest error:&error];
if (numEntities == NSNotFound) { // ERROR
//...
} else if (numEntities == 0) {
DataFeedManager *dfm = (DataFeedManager *)[NSEntityDescription insertNewObjectForEntityForName:#"DataFeedManager"
inManagedObjectContext:[self managedObjectContext]];
if (attr == checksumAttr) { //BLOCK OF INTEREST
NSString *tempVal = [[NSString alloc] initWithString:value];
[dfm setLastUpdateCheckSum:[NSString stringWithString:tempVal]];
} else if (attr == timeStampAttr) {
[dfm setTimeStamp:value];
}
} else { // more than zero entities
if (numEntities == 1) {
NSArray *fetchedObjects = [[self managedObjectContext] executeFetchRequest:fetchRequest error:&error];
if (attr == checksumAttr) { //BLOCK OF INTEREST
NSString *tempVal = [[NSString alloc] initWithString:value];
[[fetchedObjects objectAtIndex:0] setLastUpdateCheckSum:[NSString stringWithString:tempVal]]; //crashes at this line, after successfully going through the previous BLOCK OF INTEREST area
} else if (attr == timeStampAttr) {
[[fetchedObjects objectAtIndex:0] setTimeStamp:value];
}
} else { // ERROR: more than one entity
//...
}
} // else more than zero entities
[fetchRequest release];
}//setItemInDFMWhilePreservingEntityUniquenessForItem:withValue:
I have marked the areas of interest with //BLOCK OF INTEREST comments and have indicated upon which line the crash occurs (scroll right to see it!). Here is a readout of error from the console:

I believe it has something to do with copying the string adequately (can't set a string I don't own to the store). I have tried placing [value copy] as well as &value(saw this sort of thing work for someone else, so I thought I would give it a shot) to no avail. Shouldn't my current method adequately take ownership of the string? I still can't figure out what I am doing wrong. Any help appreciated. Thanks!
Best guess (based in part on this answer) is that you're passing in a released object as the value when you call the method the second time, or possibly that value is of class NSDictionary on your second time through – it's not clear from this code snippet why your method takes an argument of type id and then blithely treats it as an instance of NSString, but this may be part of the problem.
Note that your -setItemInDFMWhilePreservingEntityUniquenessForItem:withValue: accepts an arbitrary object in its second argument (type id).
Inside the method, you do:
NSString *tempVal = [[NSString alloc] initWithString:value];
Unless value is an Objective-C string, this will crash your program. In fact, your crash log shows that in that particular execution value was an NSDictionary. You need to make sure that value is an NSString.
Also, note that you own the string you’re assigning to tempVal since you’ve used +alloc. Don’t forget to release that string.

My code:
#import <Foundation/Foundation.h>
int main (int argc, const char * argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
// insert code here...
NSMutableArray *items = [[NSMutableArray alloc] init];

I think the program should output zero, one, two, three.
What Is happening here?
You wrote:
for(int i=0 <[items count];i++;)
Was that a typo? It should be:
for(int i=0; i<[items count]; i++)
for (NSString item in items) {
NSLog(#"%#", item);
}

Is my syntax for #try #catch wrong? I attempted to add a #catch block for NSRangeException but it seems that's not the right approach (it's not a class).
Also, the server error is caused by [ratable getRemoteId] sometimes returning (null) instead of an integer. This behavior seems pretty unpredictable; if anyone has a clue why ObjectiveResource might be doing that it would be helpful. But I still would like to know how to use #try #catch.
As I now understand it, throwing exceptions should only be done to alert users of your library that they have made a programming error. I am still curious why the syntax I used did not prevent the crash. I know the error was occurring several levels down; but the #try {} #catch {} block should handle all methods called by the methods I call...
At any rate, here is the fixed code, for anyone who wants to fetch scoped objects from a Rails-style restful resource.
+ (NSArray *)findAllFor:(NSObject *)ratable {
NSString *ratingsPath = [NSString stringWithFormat:#"%#%#/%#/%#%#",
[self getRemoteSite],
[ratable getRemoteCollectionName],
[ratable getRemoteId],
[self getRemoteCollectionName],
[self getRemoteProtocolExtension]];
Response *res = [ORConnection get:ratingsPath withUser:[[self class] getRemoteUser]
andPassword:[[self class] getRemotePassword]];
NSError **aError;
if([res isError]) {
*aError = res.error;
return nil;
}
else {
return [self performSelector:[self getRemoteParseDataMethod] withObject:res.body];
}
}
You don't. You fix your code to not throw an exception under these circumstances.
