Updating Parse Data in UiTableview - ios

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 (which is just going to be the screen where you save the data from) then be able to save it and it update in the parse class on the cloud. I saw this code on the parse developer website regarding updating objects Updating Objects Here
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 can I change this so that when a user clicks on the tableview cell the query runs by that specific ObjectId in parse so that I can edit the strings associated with the ObjectId. Any tutorials or guidance is really appreciated!
Here is my Tableview.m
#implementation ViewController

Display alert if no recipients are selected iOS

I have a page where we select recipients (who are friends) to send an image to. but if no recipients are selected we can still send the message. i want it so that if no recipients are selected we can show a UIAlertView. for me its not working when i try to display an alert please see my code below.
.h
#property (nonatomic, strong) NSArray *friends;
#property (nonatomic, strong) PFRelation *friendsRelation;
#property (nonatomic, strong) NSMutableArray *recipients;
- (IBAction)send:(id)sender;
.m
- (void)viewDidLoad
{
[super viewDidLoad];
self.recipients = [[NSMutableArray alloc] init];
}
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
self.friendsRelation = [[PFUser currentUser] objectForKey:#"friendsRelation"];
PFQuery *query = [self.friendsRelation query];
[query orderByAscending:#"username"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (error) {
NSLog(#"Error %# %#", error, [error userInfo]);
}
else {
self.friends = objects;
[self.tableView reloadData];
}
}];
//display camera modally etc......
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
PFUser *user = [self.friends objectAtIndex:indexPath.row];
cell.textLabel.text = user.username;
if ([self.recipients containsObject:user.objectId]) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else {
cell.accessoryType = UITableViewCellAccessoryNone;
}
return cell;
}
#pragma mark - Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self.tableView deselectRowAtIndexPath:indexPath animated:NO];
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
PFUser *user = [self.friends objectAtIndex:indexPath.row];
if (cell.accessoryType == UITableViewCellAccessoryNone) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
[self.recipients addObject:user.objectId];
}
else {
cell.accessoryType = UITableViewCellAccessoryNone;
[self.recipients removeObject:user.objectId];
}
NSLog(#"%#", self.recipients);
}
here is the part where i try to display my alert
- (IBAction)send:(id)sender {
if (!self.recipients) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Sorry" message:#"Select some friends" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
} else {
[self uploadMessage];
//we upload the message in method to parse.com
}
}
it does not seem to show for some reason so we can send messages to no one. how can i show the alert view?
Try this. Check objects of recipients is equal to 0 or not.
- (IBAction)send:(id)sender {
if ([self.recipients count]==0) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Sorry" message:#"Select some friends" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
} else {
[self uploadMessage];
//we upload the message in method to parse.com
[self.tabBarController setSelectedIndex:1];
}
}
The problem with your code is the condition that you are checking::
if (!self.recipients)
here self.recipients will always give true value as it will look for memory address of this object, which you have assigned to it in your viewDidLoad method.
You have to check for the count of the array in your scenario.

pass web link from UItableViewCell to UIWebView using parse backend

I have been stuck on this all day and I'm looking for some help. I am making an app where someone can type in a web address that web address will be stored in a table view. When the user taps on that cell it will take them to the web view where they can view that site. I am using parse as my backend to store the user input. ( I am not using PFQueryTableView)
Here is my code for the tableViewController:
interface MenuTableViewController : UITableViewController

UITableView Won't Display Data

I have a UITableView and it refuses to show any data, Xcode isn't showing any errors or warnings. Not sure why this is because the same code was working in a different app (obviously the names of array and tableview were different). I have the delegate and datasource both set as the view view-controller. If there is anything i missed please tell me!
Here is my code:
#import "ViewController.h"
#interface UIViewController ()
#end
#implementation ViewController
#synthesize CafeTableView;
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[self performSelector:#selector(RetriveData)];
[CafeTableView reloadData];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)RetriveData {
PFQuery *query = [PFQuery queryWithClassName:#"CafeList"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
NSLog(#"%#",objects);
NSLog(#"Successfully retrieved %d Cafes.", objects.count);
cafeListArry = [[NSArray alloc] initWithArray:objects];
}else{
UIAlertView *theAlert = [[UIAlertView alloc] initWithTitle:#"Error"
message:(#"There has been an error loading the Cafe List Please Try Again!")
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[theAlert show];
NSLog(#"%#",error);
}
}];
[CafeTableView reloadData];
}
//-------------------TABLE VIEW-----------------------
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return cafeListArry.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"CafeCell";
CafeListCell *cell = [CafeTableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
// Configure the cell...
PFObject *tempObject = [cafeListArry objectAtIndex:indexPath.row];
cell.title.text = [tempObject objectForKey:#"CafeName"];
cell.detail.text = [tempObject objectForKey:#"NumberOfStars"];
return cell;
}
#end
Move your call to reloadData inside the block as others have suggested and change the if condition as follows:
- (void)RetriveData {
PFQuery *query = [PFQuery queryWithClassName:#"CafeList"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (objects) {
NSLog(#"%#",objects);
NSLog(#"Successfully retrieved %d Cafes.", objects.count);
cafeListArry = [[NSArray alloc] initWithArray:objects];
[CafeTableView reloadData]; // HERE
}else{
UIAlertView *theAlert = [[UIAlertView alloc] initWithTitle:#"Error"
message:(#"There has been an error loading the Cafe List Please Try Again!")
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[theAlert show];
NSLog(#"%#",error);
}
}];
}
Also, as suggested by Lyndsey in the comments, change the following line
cell.detail.text = [tempObject objectForKey:#"NumberOfStars"];
to
cell.detail.text = [[tempObject objectForKey:#"NumberOfStars"] stringValue];
because you said that it's a number, not a string.
Please check the delegates are connected in xib file or not if not then please connect properly and please call the [tableview reloadData]; method at the time when you want bind the data with table

Nothing shows in custom headerView

When I run the application, the header view container space is there, and is visible. I'm trying to display the username inside the header view, but nothing is showing up. Here is my code so far in the tableView:

#interface HomeView () <UIActionSheetDelegate, UIImagePickerControllerDelegate>

The code above, you are updating the headerview UI from a background thread. You need to wrap the UI part so it performs on the main thread.
dispatch_async(dispatch_get_main_queue(), ^{
[headerView.userButton setTitle:username forState:UIControlStateNormal];
};
You need to be careful though, you are performing a background operation and then updating the header which you are reusing. There is a chance that the header is reused for a new section before the operation finishes and it is then set with the wrong username for that section. You can take care of this by not reusing the header or canceling the network operation if the header scrolls off screen before the operation finishes.

Retrieving objects from parse into table view cell

I have created an object and saved it to the backend named NewCar and there are 4 strings attached to which are year, make, model, horsepower I'm having troubles pulling the data from parse and placing it into my table here is a few pieces of my code.
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
PFQuery *query = [PFQuery queryWithClassName:#"NewCar"];
[query whereKey:#"year" equalTo:[[PFUser currentUser] objectId]];
[query orderByAscending:#"createdAt"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (error) {
} else {
self.cars = objects;
[self.tableView reloadData];
}
}];
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [self.cars count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"garageCell";
garageCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil)
{
cell = [[garageCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.usernameDisplay.text = [[PFUser currentUser] objectForKey:#"username"];
//I need to display the year, make and model below here.
cell.carYearLabel.text = [[PFObject objectWithClassName:#"NewCar"] objectForKey:#"year"];
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 236;
}
I am able to display the username in my custom cell, but can't figure out how to display the year, make and model values. Any help would be much appreciated.
I have been looking through the documentation in Parse and can't seem to figure it out just in case you are wondering if I tried there.
I also want to add in the code where I added the object to Parse this might help in figuring this out as well.
- (IBAction)save:(id)sender {
NSString *year = self.carYear.text;
NSString *make = self.carMake.text;
NSString *model = self.carModel.text;
NSString *horsepower = self.carHorsepower.text;
if ([year length] == 0 || [make length] == 0 || [model length] == 0 || [horsepower length] == 0) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:nil message:#"You might have missed a field" delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alertView show];
} else {
PFObject *newCar = [PFObject objectWithClassName:#"NewCar"];
newCar[#"year"] = year;
newCar[#"make"] = make;
newCar[#"model"] = model;
newCar[#"horsepower"] = horsepower;
[newCar saveInBackground];
[self.navigationController popToRootViewControllerAnimated:YES];
}
}
Okay so instead of using
cell.carYearLabel.text = [[PFObject objectWithClassName:#"NewCar"] objectForKey:#"year"];
You can use the following
cell.carYearLabel.text = [self.cars objectForKey:#"NewCar"] valueForKey:#"year"];
