I have MBProgressHUD implemented into my objective-c project and while the progressHUD starts my app crashes. Here is my log

Also this line of code gets a signal SIGABRT error:
[targetForExecution performSelector:methodForExecution withObject:objectForExecution];
Edit:
// MBProgressHUD
HUD = [[MBProgressHUD alloc] initWithView:self.view];
HUD.labelText = #"Uploading to Cloud...";
HUD.detailsLabelText = #"Just relax";
HUD.mode = MBProgressHUDModeAnnularDeterminate;
[self.view addSubview:HUD];
[HUD show:YES];
[HUD showWhileExecuting:#selector(load) onTarget:self withObject:nil animated:YES];
-(NSArray*) load: (NSString *) componentName
{
float progress = 0.0;
while (progress < 1.0) {
progress += 0.01;
HUD.progress = progress;
usleep(50000);
}
}
Try edit this code:
[HUD showWhileExecuting:#selector(load) onTarget:self withObject:nil animated:YES];
To:
[HUD showWhileExecuting:#selector(load:) onTarget:self withObject:nil animated:YES];
Transform load method in (void)
- (void) load {
}
Your code:
- (void) load {
{
float progress = 0.0;
while (progress < 1.0) {
progress += 0.01;
HUD.progress = progress;
usleep(50000);
}
}

I am trying to populate a table view with the file names of the files located in the documents directory but when the button is clicked to show the table view the app crashes saying that the object at index is 0. but there are 14 objects in the array. What could be the fault?

The Segue:
-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
NSIndexPath *selectedPath = [self.tableView indexPathForCell:sender];
AirconsoleDevice *selectedDevice = self.manager.defaultDevice;
if (selectedPath.section == 0) {
selectedDevice = self.currentDevices[selectedPath.row];
}
if ([segue.identifier isEqualToString:#"session_details"]) {
AirconsoleSession *session = [[AirconsoleSession alloc] initWithDevice:selectedDevice];
currentSession = session;
SessionDetailsVC *sdvc = segue.destinationViewController;
sdvc.session = session;
} else {
// we are presenting the Device Details
DeviceDetailsTVC *ddvc = [segue.destinationViewController viewControllers][0];
ddvc.device = selectedDevice;
}
}
The problem is in this line
DeviceDetailsTVC *ddvc = [segue.destinationViewController viewControllers][0];
ddvc.device = selectedDevice;
The destination controller is I assume a Navigation controller. And you are accessing the first controller in the stack.
Check this is actually set up correctly in the Storyboard. Because thats what the line of code expects, but the crash says it cannot find any member in the viewControllers array.
AFAIK it has nothing to do with the table view and 14 items.
I'm using the UNIRest library and I'm trying to switch to another ViewController on the response of an HTTP GET method.
[[UNIRest get:^(UNISimpleRequest *request) {
[request setUrl:GEtFamilyMembers];
}] asJsonAsync:^(UNIHTTPJsonResponse* response, NSError *error) {
NSLog(#"res: %#", response.body);
if (response.code == 200) {
GCHFamilyMembersViewConroller* fmViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"gchFamilyMembers"];
self.navigationController.viewControllers = #[fmViewController];
[self.mm_drawerController setCenterViewController:self.navigationController withCloseAnimation:YES completion:nil];
} else {
[self showToast:#"Something went wrong, Please try again after some time."];
}
}];
Even after printing the response using NSLog. Nothing happens for about 30 seconds. Then suddenly app crashes.
I thought it's because Asynch call blocks UI so I tired a method like:
- (void) gotoSelectFamilyMembers {
dispatch_async(dispatch_get_main_queue(), ^{
GCHFamilyMembersViewConroller* fmViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"gchFamilyMembers"];
self.navigationController.viewControllers = #[fmViewController];
[self.mm_drawerController setCenterViewController:self.navigationController withCloseAnimation:YES completion:nil];
});
}
but still the app crashes.
Earlier when I was using a Synchronous call it was working. But not now.
Please help!

});
You're using the asynchronous calls of Unirest and the response should be called on the UI thread (Main thread). Usually libraries similar to this deliver the result on the main thread. Therefore, I think you do not need to specifically call dispatch_async on the main queue. However, you can use the following check to see whether it gets called on the main thread or not.
[[NSThread currentThread] isMainThread] ? NSLog(#"MAIN THREAD") : NSLog(#"NOT MAIN THREAD");
Here's what I suspect
Your ViewController creation method has some fault and is consuming time
Your response is very large
I suggest that you call the following without any web service calls to confirm that they do not cause the crash.
GCHFamilyMembersViewConroller* fmViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"gchFamilyMembers"];
self.navigationController.viewControllers = #[fmViewController];
[self.mm_drawerController setCenterViewController:self.navigationController withCloseAnimation:YES completion:nil];
Please help me with my school project, currently i suppose to retrieve a set of record from the database and display the record based on their category.
I am new to IOS programming so please help me.
If possible please explain to me what is my mistake and possible solution to solve it.
Sorry to be rude, i need the solution to solve it as soon as possible cause i also need to work on other part of the project.

From the crash log posted, it seems that your problem is in PFObject *searchUser = [self.SearchResults objectAtIndex:indexPath.row];
But that would be strange if you already use return self.SearchResults.count; in - (NSInteger) Tableview: (UITableView *) Tableview numberOfRowsInSection: (NSInteger) section
The first thing that comes to my mind is where you call [self.SearchResults removeAllObjects]; in - (void) filterResults: (NSString *)searchTerm , I suggest using the below code:
- (void) filterResults: (NSString *)searchTerm{
PFQuery * query = [PFQuery queryWithClassName: self.parseClassName]; // table in which you are looking for
[query whereKeyExists: # "mName"]; // column which you are looking for
[query whereKey: # "mName" containsString : searchTerm];
NSArray * results = [query findObjects];
self.SearchResults = [results mutableCopy];
}
Update:
Since it crashes with the first typing, then make sure that numberOfRowsInSection returns self.SearchResults.count not self.objects.count, if it does but doesn't return zero, try replacing self.searchResults = [NSMutableArray array]; with self.searchResults = [[NSMutableArray alloc] init]; in your viewDidLoad
Hope it solves your issue.
I think you don't initializate the mutable array change
self.searchResults = [NSMutableArray array];
to
self.searchResults = [NSMutableArray alloc]init];
I've been working on this for a few days. Any idea what this means? please help!
let me know if more info is required

I found a solution with help from other posts. It turned out to be a timing issue. I created another method to reset my location manager and I call it with a delay. This fixed everything. Hope this helps you too.
