iOS,GMSMapView, MapView:didTapMarker app crash - ios

my app is crashed when the user tapped on a marker (GMSMapVIew: didTapMarker) and myApp works good in 99% of the time, But sometimes it shows a crash on crashlytics. And it's so random occurred.
The crash report shows the following.

Does anybody have an idea?
Please help me, Because I'm facing this issue form a very long time
Thanks!

MLKit Digital Ink Recognition in unity error when download model

I'm developing an app with Unity that uses Digital Ink Recognition of ML Kit to recognize handwriting.
To fetch ios plugin via unity, I use this script:
public static void Initialize(string languageTag = "en-US")
{
if (_instance != null)
{
return;
}
Debug.Log("Initializing...");
GameObject owner = new GameObject("HandwriteRecognitionIOSPluguin");
_instance = owner.AddComponent<HandwriteRecognitionIOSPluguin>();
_InitializeNew(languageTag);
}
from the above function will be directed to the objective-c script with the following script:
static DigitalInkRecognition* recognition = nil;
extern "C" void _InitializeNew(const char* languageTag)
{
if (recognition == nil)
recognition = [[DigitalInkRecognition alloc] init];
[recognition downloadModel];
}
the following is the script in the objective-c file
#import <GoogleMLKit/MLKit.h>
#interface DigitalInkRecognition : NSObject
#property(nonatomic) MLKDigitalInkRecognitionModel *model;
#property(nonatomic) MLKModelManager *modelManager;

What can I do to solve the problem I'm having?
Thanks in advance for any idea.

Why does my app crash when backgrounding when using [NSAttributedString initWithData]

I have a viewController that manages a UICollectionView. I have a helper method that is called from cellForItemAtIndexPath that provides an NSAttributedString for a label in the cell. The helper method formats an NSAttributedString from an html string. The app will crash when moving to the background, but only if the indexPath.item is greater than 1. In other words, I can exit the app without crashing from the first or second cell, but crash consistently on the third, forth, ... cell.
Here are my helper method and stack trace. Any idea why I am crashing on exiting the app?

libc++abi.dylib: terminating with uncaught exception of type NSException
I've come across this issue too, after a few hours, i've found a solution for this one.
You'll just need to wrap the code for converting the NSAttributedString into dispatch_async.
For example:
DispatchQueue.MainQueue.DispatchAsync(() =>
{
var encodingData = ((NSString)html).Encode(NSStringEncoding.Unicode, true);
NSAttributedString data = new NSAttributedString(
encodingData,
new NSAttributedStringDocumentAttributes()
{
DocumentType = NSDocumentType.HTML,
}, ref error);
});
I'm using Xamarin, so these are C# code, but i believe they're similar in Swift and Obj C.
Look like when the system is making transition between pages (view controller), it will try to prevent any heavy task running on UI Thread. Which cause this issue.

Objective-C crash

I'm checking self.next_id is not null why would this line crash? I can't reproduce the issue on my test devices. I only get crash reports from Crashlytics at this line.
-(Second*)getNextSecond:(BOOL)returnSelf{
Second* retValue = nil;
if(self.next_id){
//this line !!!!
retValue = [[SecondDatabase sharedManager] getSecond:[self.next_id stringValue]];
}
if (retValue == nil && returnSelf) {
return self;
}else{
return retValue;
}
}
This is my SecondDatabase sharedManager function:
#property NSMutableDictionary* dictionary;
- (id)init {
if (self = [super init]) {
_dictionary = [#{} mutableCopy];
}
return self;
}
+ (id)sharedManager {
static SecondDatabase *sharedMyManager = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
sharedMyManager = [[self alloc] init];
});
return sharedMyManager;
}
This is my getSecond function:
-(Second*)getSecond:(NSString*)idString{
return [_dictionary objectForKey:idString];
}
Where should I be investigating? Would this crash if dictionary didn't have object for key so that it returns NULL?

NSCFDictionary - Unrecognized selector sent to instance

I have two modes - Mode 1 and Mode 2 which can be switched by a central button. Switch between modes allows user to see two different types of clustered annotations.
I can switch from Mode 1 to Mode 2 easily, but when I switch back to Mode 1 I'm getting this nasty error
-[__NSCFDictionary componentsSeparatedByString:]: unrecognized selector sent to instance 0x7fb1308cca50
I'm opening my code and in the TBClusteredAnnotations.m (script I'm using for clusterization). I have the following snippet of code relating to componentsSeparatedByString:
TBQuadTreeNodeData TBDataFromLine(NSString *line)
{
NSString *separator=#">>>>>>>>";
NSArray *components = [line componentsSeparatedByString: separator];
double latitude = [components[0] doubleValue];
double longitude = [components[1] doubleValue];
TBUserInfo* userInfo = malloc(sizeof(TBUserInfo));
NSString *userName = [components[2] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
userInfo->userId = malloc(sizeof(char) * userName.length + 1);
strncpy(userInfo->userId, [userName UTF8String], userName.length + 1);
NSString *userId = [components [3] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
userInfo->userImage = malloc(sizeof(char) * userId.length + 1);
strncpy(userInfo->userImage, [userId UTF8String], userId.length + 1);
return TBQuadTreeNodeDataMake(latitude, longitude, userInfo);
}
but I'm loading my annotations with the following code in the MainViewController:
-(void)annotationsmode1:(NSMutableArray*)marr
{
if(marr.count>0)
{
NSMutableArray *newMarr1=[NSMutableArray new];
NSString *separatestuff=#">>>>>>>>";
for(NSMutableDictionary *dic in marr)
{
NSString *newStr=[NSString stringWithFormat:#"%#%#",[dic[#"latitude"] isEqualToString:#""]?#" ":dic[#"latitude"],separatestuff];
newStr=[NSString stringWithFormat:#"%#%#%#",newStr,[dic[#"longitude"] isEqualToString:#""]?#" ":dic[#"longitude"],separatestuff];
newStr=[NSString stringWithFormat:#"%#%#%#",newStr,[dic[#"id"] isEqualToString:#""]?#" ":dic[#"id"],separatestuff];
newStr=[NSString stringWithFormat:#"%#%#",newStr,[dic[#"image"] isEqualToString:#""]?#" ":dic[#"image"]];
[newMarr1 addObject:newStr];
}
//NSLog(#"NEW Array: %#",newMarr);
[self.coordinateQuadTree buildTree:newMarr1];
}
}
-(void)annotationsmode2:(NSMutableArray*)marr
{
if(marr.count>0)
{
NSMutableArray *newMarr=[NSMutableArray new];
NSString *separatestuff2=#">>>>>>>>";
for(NSMutableDictionary *dic in marr)
{
NSString *newStr=[NSString stringWithFormat:#"%#%#",[dic[#"lat"] isEqualToString:#""]?#" ":dic[#"lat"],separatestuff2];
newStr=[NSString stringWithFormat:#"%#%#%#",newStr,[dic[#"lang"] isEqualToString:#""]?#" ":dic[#"lang"],separatestuff2];
newStr=[NSString stringWithFormat:#"%#%#%#",newStr,[dic[#"id"] isEqualToString:#""]?#" ":dic[#"id"],separatestuff2];
newStr=[NSString stringWithFormat:#"%#%#",newStr,[dic[#"image"] isEqualToString:#""]?#" ":dic[#"image"]];
[newMarr addObject:newStr];
}
//NSLog(#"NEW Array: %#",newMarr);
[self.coordinateQuadTree buildTree:newMarr];
}
}
UPDATE: This is the block of code where the TBDataFromLine is used
- (void)buildTree:(NSMutableArray *)lines
{
#autoreleasepool {
NSInteger count = lines.count - 1;
TBQuadTreeNodeData *dataArray = malloc(sizeof(TBQuadTreeNodeData) * count);
for (NSInteger i = 0; i < count; i++) {
dataArray[i] = TBDataFromLine(lines[i]);
}
//TBBoundingBox world = TBBoundingBoxMake(19, -166, 72, -53);
TBBoundingBox world = TBBoundingBoxMake(0,0,100,100);
_root = TBQuadTreeBuildWithData(dataArray, count, world, 4);
}
}
I've been working on this issue for hours now and still have no clue.
UPDATE: Here is the debugger's log I'm getting

Add an Exception break point and it will take to exactly to that line where that crash is happening. Also check 'line' cause it is changed to dictionary but you code expect it
to be a string
There is no [] operator on NSArray or NSMutableArray.
You need this:
for (NSInteger i = 0; i < count; i++) {
dataArray[i] = TBDataFromLine([lines objectAtIndex:i]);
}
Using [] on NSArray* effectively acted like "lines" was really a pointer to an array of NSMutableArray instances, whereas you wanted to get one of the items out of the array to which it pointed.

Crash on KVO code, how do I fix this?

[self.kvoController observe:user keyPath: #"fullName" options:NSKeyValueObservingOptionNew block:^(id observer, id object, NSDictionary *change) {
dispatch_async(dispatch_get_main_queue(), ^{
NSString *fullname = [change objectForKey:NSKeyValueChangeNewKey];
if ([fullname isKindOfClass:[NSString class]]) {
if (![weakSelf.fullnameLabel.text isEqualToString: fullname]) {
weakSelf.fullnameLabel.text = fullname;
[weakSelf.fullnameLabel sizeToFit];
}
}
});
}];
This code crashes on the 3rd line NSString *fullname = [change objectForKey:NSKeyValueChangeNewKey];
The crash log is as below:
