Unable to handle setEditing method through UIBarButtonItem - objective-c

I have added a bar button item in my tool bar and I implemented its functionality in the method given below. I am not able, however, to display a delete button in each row. How can I do this?
-(void)setEditing:(BOOL)editing
animated:(BOOL)animated
{
[super setEditing:editing
animated:animated];
[editButton setEnabled:!editing];
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
NSString *selectedFile = (NSString*) [directoryContents objectAtIndex: indexPath.row];
NSString *selectedPath = [directoryPath stringByAppendingPathComponent:selectedFile];
BOOL canWrite = [[NSFileManager defaultManager] isWritableFileAtPath:selectedPath];
if(!canWrite)
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"status"
message:#"path isnt writable"
delegate:nil
cancelButtonTitle:#"cancel"
otherButtonTitles:nil];
[alert show];
[alert release];
}
NSError *err = nil;
if(! [[NSFileManager defaultManager] removeItemAtPath:selectedPath error:&err])
{
UIAlertView *alert1 = [[UIAlertView alloc] initWithTitle:#"status"
message:#"cannot delete"
delegate:nil
cancelButtonTitle:#"cancel"
otherButtonTitles:nil];
[alert1 show];
[alert1 release];
}
// Delete the row from the data source.
NSArray *deletedPaths = [NSArray arrayWithObject: indexPath];
[self loadDirectoryContents];
[self.tableview deleteRowsAtIndexPaths:deletedPaths withRowAnimation:YES];
}
}

The button on the toolbar will need to be connected to an interface action in the custom table view controller subclass. Define the action as follows -
- (IBAction)startEditing {
[self setEditing:YES animated:YES];
}
-(void)setEditing:(BOOL)editing
animated:(BOOL)animated
{
[super setEditing:editing
animated:animated];
[editButton setEnabled:!editing];
}
You will have to implement the delegate method tableView:editingStyleForRowAtIndexPath and return UITableViewCellEditingStyleDelete for the rows you wish to enable it.

Updating/Editing Parse Object by UITableview Cell (Objective C)

I have a tableview that is full of current user data that is stored in parse. I want to be able to click on the cell of the parse data and be able to edit that data in a edit screen then be able to save it and it update in the parse class. I saw this code on the parse developer website regarding updating objects https://parse.com/docs/ios/guide#objects-updating-objects
PFQuery *query = [PFQuery queryWithClassName:#"GameScore"];
[query getObjectInBackgroundWithId:#"xWMyZ4YEGZ"
block:^(PFObject *gameScore, NSError *error) {
gameScore[#"cheatMode"] = #YES;
gameScore[#"score"] = #1338;
[gameScore saveInBackground];
}];
but the problem is that in the
[query getObjectInBackgroundWithId:#"xWMyZ4YEGZ"
block:^(PFObject *gameScore, NSError *error)
is a query by the specific ObjectId that is stated. How do I change this so that when a user clicks on the tableview cell the query runs by that specific ObjectId in parse so I can edit the strings associated with the ObjectId. Any tutorials or guidance is really appreciated!
Here is my Tableview.m
#implementation ViewController
- (id)initWithCoder:(NSCoder *)aCoder
{
self = [super initWithCoder:aCoder];
if (self) {
// Custom the table
// The className to query on
self.parseClassName = #"rep";
// The key of the PFObject to display in the label of the default cell style
self.textKey = #"name";
// Whether the built-in pull-to-refresh is enabled
self.pullToRefreshEnabled = YES;
// Whether the built-in pagination is enabled
self.paginationEnabled = NO;
// The number of objects to show per page
//self.objectsPerPage = 10;
}
return self;
}

TapGesture by UITableView

I try to open an AlertView even I hold the tableview row 0.5 seconds.
I use for that following code:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
UILongPressGestureRecognizer *longTap = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:#selector(handleTapGesture:)];
[longTap setMinimumPressDuration:0.5];
longTap.delegate = (id)self;
[self.view addGestureRecognizer:longTap];
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
NSString *cellText = cell.textLabel.text;
[[NSUserDefaults standardUserDefaults] setObject:cellText forKey:#"CellNameToEdit"];
}
- (void)handleTapGesture:(UILongPressGestureRecognizer *)sender{
if (sender.state == UIGestureRecognizerStateBegan) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Titel" message:#"message" delegate:self cancelButtonTitle:#"cancel" otherButtonTitles:nil, nil];
alert.tag = 1;
[alert show];
}
}
This code will work, but the problem is, I have to click the row first before it opens the alert view. I hope you understand what I mean.
Why are you adding UILongPressGestureRecognizer to self.view if you want it to get called when you click table..add UILongPressGestureRecognizer to your UITableView([self.youTableViewName addGestureRecognizer:longTap]) and it will work fine.
For more insight of how to do it..check out below link..
https://stackoverflow.com/a/3924965/1865424
I have used below GestureRecognizer Code, may be Helpful to You.
#pragma mark - View Controller Life Cycle
#implementation ViewController <UIGestureRecognizerDelegate>
- (void)viewDidLoad
{
UILongPressGestureRecognizer *gesture1 = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:#selector(gestureAction:)];
[gesture1 setDelegate:self];
[gesture1 setMinimumPressDuration:1];
Tableview.userInteractionEnabled = YES;
[Tableview addGestureRecognizer:recognizer];
}
#pragma mark - DidSelcelect kindof method
-(void)gestureAction:(UITapGestureRecognizer *) sender
{
CGPoint touchLocation = [sender locationOfTouch:0 inView:self.Tableview];
//here is indexpath
NSIndexPath *indexPath = [self.Tableview indexPathForRowAtPoint:touchLocation];
NSLog(#"%ld", (long)indexPath.row);
//Do here what you want to do with Cell
[self.Tableview selectRowAtIndexPath:indexPath
animated:YES
scrollPosition:UITableViewScrollPositionNone];
}

reload data in TableView after inserting data through web service

I am using JSON parsing to upload data in UITableView. Everything is working fine but after inserting data through textView it's uploading on server but it's not refreshing in my previous and current UITableView. I need to restart my project to see the uploaded data. I want to reload my UITableView after inserting data. I used [self.myTableView reloadData] but it's not working anywhere.
-(PrayerListCustomCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:
(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
PrayerListCustomCell *cell = (PrayerListCustomCell *)[tableView
dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[NSBundle mainBundle]loadNibNamed:#"PrayerListCustomCell"
owner:self options:nil]objectAtIndex:0];
}
cell.dateLbl.text = [dateList objectAtIndex:indexPath.row];
cell.prayerLbl.text = [prayerList objectAtIndex:indexPath.row];
return cell;
}
-(void)submitClicked
{
if ([prayerTextView.text isEqualToString:#""]) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:#"Please fill
your request in text box!" delegate:self cancelButtonTitle:#"OK"
otherButtonTitles:nil, nil];
[alert show];
}
else
{
prayerSubmitData = prayerTextView.text;
SubmitPrayer *submit = [[SubmitPrayer alloc]init];
[ASKevrOperationManager submitPrayer:submit handler:^(id object , NSError *error
, BOOL success)
{
if (success) {
NSLog(#"this is request data = %#",object);
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil
message:#"Successful upload!" delegate:nil cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
prayerTextView.text = #"";
[self.requestTableView reloadData];
//Do refreshment code
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil
message:#"Please try again later!" delegate:nil cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
} ];
}
}
You need to add your committed data into your prayerList array. This should be something like this:
if (success) {
// show alert
[prayerList addObject:prayerTextView.text];
[self.requestTableView reloadData];
prayerTextView.text = #"";
//Do refreshment code
}

Multiselect table view controller items for email attachment

Here is my XCode 4.3.2 problem... I have a table displaying multi-select NSArray data in a table controller. I would like to select multiple items in the table, click a button on the bottom of the view controller, and attach the selected documents in the project that are referenced in the table's NSArray to an email message. I have the email portion working ok, but not attaching anything. I also have the multi-select check marks working correctly. Any ideas on getting multi-select attachment accomplished? I assume I have to build a mutableArray in which the table data cell text = the local PDF file name.???
Here is some of my code that I think will have to be edited for building the array?
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath];
if ([selectedCell accessoryType] == UITableViewCellAccessoryNone) {
[selectedCell setAccessoryType:UITableViewCellAccessoryCheckmark];
[selectedIndexes addObject:[NSNumber numberWithInt:indexPath.row]];
NSLog(#"Items I selected # %d:", indexPath.row);
NSLog(#"Items I selected: %#", selectedIndexes);
} else {
[selectedCell setAccessoryType:UITableViewCellAccessoryNone];
[selectedIndexes removeObject:[NSNumber numberWithInt:indexPath.row]];
NSLog(#"Items I de-selected # %d:", indexPath.row);
}
[tableView deselectRowAtIndexPath:indexPath animated:NO];
}
The mail component:
- (IBAction)sendMailButton:(id)sender {
{
if ([MFMailComposeViewController canSendMail])
{
MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
mailer.mailComposeDelegate = self;
[mailer setSubject:#"Documentation Attached"];
[mailer setMessageBody:#"Attached are documents from staff." isHTML:NO];
//[mailer setMessageBody:emailBody isHTML:NO];
//iPad presentation enhancement:
mailer.modalPresentationStyle = UIModalPresentationPageSheet;
[self presentModalViewController:mailer animated:YES];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error"
message:#"Your device doesn't support the composer sheet"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
}
}

Why does the pushViewController stop working when I remove a UIAlertView

I outsourced some iPhone development and I am trying to make a simple change to the code, but it does not make any sense to me. I am hoping that someone can help me out. I would ask the original developer, but they just left for a week long vacation and I would prefer to not wait.

The part in question is this

On the surface it seems really simple. The change I want to make is to remove this alert
UIAlertView *LoginOK=[[UIAlertView alloc]initWithTitle:#"Authentication" message:#"Authenticated successfully!!!" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[LoginOK show];
[LoginOK release];
However, any change to the alert causes the pushViewController to stop working. I have tried commenting the alert out,
if ([self.validuser isEqualToString:#"Authenticated Successfully"])
{
if (app.Authorisation==TRUE)
{
// UIAlertView *LoginOK=[[UIAlertView alloc]initWithTitle:#"Authentication" message:#"Authenticated successfully!!!" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
//[LoginOK show];
//[LoginOK release];
}
else
{
MainViewController *main=[[MainViewController alloc]init];
[self.navigationController pushViewController:main animated:YES];
[main release];
}
}
else
{
UIAlertView *LoginError=[[UIAlertView alloc]initWithTitle:#"Authentication" message:self.validuser delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[LoginError show];
[LoginError release];
}
}
I have tried rewriting the second if
if ([self.validuser isEqualToString:#"Authenticated Successfully"])
{
if (app.Authorisation==FALSE)
{
MainViewController *main=[[MainViewController alloc]init];
[self.navigationController pushViewController:main animated:YES];
[main release];
}
}
else
{
UIAlertView *LoginError=[[UIAlertView alloc]initWithTitle:#"Authentication" message:self.validuser delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[LoginError show];
[LoginError release];
}
}
I have also tried completely removing the second if
if ([self.validuser isEqualToString:#"Authenticated Successfully"])
{
MainViewController *main=[[MainViewController alloc]init];
[self.navigationController pushViewController:main animated:YES];
[main release];
}
else
{
UIAlertView *LoginError=[[UIAlertView alloc]initWithTitle:#"Authentication" message:self.validuser delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[LoginError show];
[LoginError release];
}
}
But the pushViewController will not work unless I have the alert in the code. I don't get any error, and the app does not crash, it just stays in the current page, so I am completely at a loss. It makes me think their is some action that is triggered by clicking "OK" in the alert, but I don't see anything in the code.
I have also stepped through the code to see if I can spot the problem but it seems fine.
In case it matters I am using xcode 4.2 and iOS 5 sdk.
Another strange occurance is that if I run the code like this
if ([self.validuser isEqualToString:#"Authenticated Successfully"])
{
MainViewController *main=[[MainViewController alloc]init];
[self.navigationController pushViewController:main animated:YES];
[main release];
}
else
{
UIAlertView *LoginError=[[UIAlertView alloc]initWithTitle:#"Authentication" message:self.validuser delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[LoginError show];
[LoginError release];
}
and I get a login error (meaning it triggers the alert in the else). Then after clicking ok it moves on to the next page. I really don't understand how this could happen since they are in different part of the if. I must be missing something obvious.
The Uialertview delegate method never gets called, therefore never dismisses the modal view controller
- (void)alertView:(UIAlertView *)ConfirmationAlert didDismissWithButtonIndex:(NSInteger)buttonIndex
Just dismiss the view controller next to the commented code
[self dismissModalViewControllerAnimated:YES];
app.Authorisation=FALSE;
I may be totally off base here, but did you try removing the entire block;
if (app.Authorisation==TRUE)
{ ***STARTING HERE
UIAlertView *LoginOK=[[UIAlertView alloc]initWithTitle:#"Authentication" message:#"Authenticated successfully!!!" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[LoginOK show];
[LoginOK release];
}
else
{
MainViewController *main=[[MainViewController alloc]init];
[self.navigationController pushViewController:main animated:YES];
[main release];
} ***ENDING HERE
}
If you remove the alert then the delegate methods won't be called.
This part here:
- (void)alertView:(UIAlertView *)ConfirmationAlert didDismissWithButtonIndex:(NSInteger)buttonIndex {
if([ConfirmationAlert.title isEqualToString:#"Authentication"]) {
[self dismissModalViewControllerAnimated:YES];
app.Authorisation=FALSE;
}
}
Just put the code inside the if-block above into the block where you removed the alert.
