***Updated Question ******
The JSON data is the Gym Classes for all week .
At the moment I am downloading and saved the JSON data to An NSObject SearchResult then display on my UItableviewController one row per gym Class.
But I want to Group items (Gym Classes) By Day and display each day on is own table.
So my question is do I need to group items by date "DAY_OF_WEEK" and store each day in to is own array (MonArray ... SunArray)?
or collect all the data Like I am doing now and sort the array in to groups for each day?
I hope this make sense.
thanks for your help .

I'm working on a tableview that displays data about a company. I want to divide the data over 3 sections, to make it look more organized.
The data about a company is retreived from a mysql database and I receive it in one array, which looks like this:
{
companyAdress = "the street 9";
companyCity = "city";
companyFacebook = "facebook.com/companyname";
companyName = "name";
companyPhoneNumber = "0123 456 789";
companyTwitter = "www.twitter.com/companyname";
companyWebsite = "www.companyname.com";
companyZip = "0000 AA";
imageNumber = "3067913";
}
I want the companyName and imageNumber in the first section, the companyAdress, companyZip and companyCity in the second, and all the remaining variables in the third section.
I do not know how to properly do this, and I haven't found a useful answer/solution for this on SO or any other website I know.
How to I do this? any help, sample code and/or tutorial would be much appreciated, thank you in advance!
One approach would be to separate the data when you receive it into a two-dimensional array. So the array's first entry would be an array holding companyName and imageNumber, and so on.
With this implementation, numberOfSectionsInTableView would simply return myArray.count and numberOfRowsInSection would return myArray[section].count.
To access the appropriate values from there, you would do something like ((NSMutableArray*)myArray[indexpath.section])[indexpath.row]
You must use a Array of NSDictionary items,
then you get info for sections and tables rows.
adding a key for each record type.
This is a sample project for explain the use of NSArray and NSDictonary, I hope this help you.
You can download the xcode project from here http://www.germinara.it/download/FGTestTableView.zip and this is the result of the sample http://www.germinara.it/download/FGtesttableview.png

Im developing an app, need to load some data in background , then show the data using UITableView.
Here are some codes,
loading data in background:
- (void)loadRelatedItems
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
for (NSString *mediaType in allMediaTypes)
{
[self performSelector:#selector(loadRelatedItems:) withObject:mediaType];
}
NSString *notificationName = [CommonFunction allRelatedItemsLoadedNotificationName];
[[NSNotificationCenter defaultCenter] postNotificationName:notificationName object:self userInfo:nil];
[pool release];
}
- (void)loadRelatedItems:(NSString *)mediaType
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
for (NSString *keyword in _keywords)
{
NSURL *URL = [NSURL URLWithString:[NSString stringWithFormat:#"%#&mediaType=%#&keyword=%#", API, mediaType, keyword]];
NSMutableArray *items = [CommonFunctions arrayFromURL:URL];
if ([items count] == 0) continue;
NSString *notificationName = [CommonFunction partialRelatedItemsLoadedNotificationName];
NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys:items, #"items", mediaType, #"mediaType", nil];
[[NSNotificationCenter defaultCenter] postNotificationName:notificationName object:self userInfo:dic];
}
[pool release];
}
showing the data in UITableView:

{
NSDictionary *dic = [sender userInfo];
NSString *mediaTypeString = [dic objectForKey:#"mediaType"];
NSMutableArray *items = [dic objectForKey:#"items"];
dispatch_async(dispatch_get_main_queue(), ^{
if ([_relatedItems count] == 0)
{
[_relatedItems setObject:items forKey:mediaTypeString];
[_tableView reloadData];
}
else
{

if (mediaTypeItems)
{
// section exist

I'm very confused that it works fine some times, but some times it crashed with message:
*** Assertion failure in -[UITableView _endCellAnimationsWithContext:], /SourceCache/UIKit_Sim/UIKit-1912.3/UITableView.m:1030
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of sections. The number of sections contained in the table view after the update (0) must be equal to the number of sections contained in the table view before the update (2), plus or minus the number of sections inserted or deleted (0 inserted, 0 deleted).
What's the problem? please help.
Please make sure after updating, your number of sections should be equal to number of sections before the update.
As per your code :
the number of sections are defined as like this:
if ([_relatedItems count] == 0) {
return 1;
} else {
return [_relatedItems count];
}
and in this case you are creating new section right ?
else { // new section
[_relatedItems setObject:items forKey:mediaTypeString];
NSInteger section =[[[_relatedItems allKeys] sortedArrayUsingSelector:#selector(mediaTypeCompare:)] indexOfObject:mediaTypeString];
NSIndexSet *indexSet = [NSIndexSet indexSetWithIndex:section];
[_tableView beginUpdates];
[_tableView insertSections:indexSet withRowAnimation:UITableViewRowAnimationNone];
[_tableView endUpdates];
}
If you are creating new section then your [_relatedItems count] is increasing. So, please make sure after the inserting also your count should be same.
Right ?
Try This :
if ([_relatedItems count] == 0) {
return 1;
} else {
if([_relatedItems count]>previousCount)
return [_relatedItems count];
return previousCount;
}
when ever you are making any updates to the [_relatedItems]; then change update your previousCount also.. this will be solved
I think your problem is with the number of rows method in the datasource just do one thing define int noOfRows in your .h file .assign your table view array count with the noOfRows. noOfRows=[yourtableArray count];
then return noOfRows from table views numberOfRowsInSection method.
Add 1 to noOfRows if you insert row in the table.
Make noOfRows-- when you delete row from the table
You will not get this exception .Update your array as per your requirement.
If this is a repost, I apologize, but I have been scouring the net and cant seem to find anything that works. I have a list of workouts that I display in a tableview that are gathered in plists in the bundle. There is a also a separate tab that I have that allows a user to build their own workouts and save them in the documents folder plist file. Once they are saved, they are added to the table view. In the simulator, everyuhting works fine. But on the actual device, it is not updated unless I close the program for an extended period of time, reload the program from xcode, or turn the phone off. I have tried adding [[self tableview] reload] to "viewDidLoad", "viewWillappear", and "viewDidAppear" and none of them work. Once again, the file is saved, the updating does work in the simulator, and it doesn't update in the phone right away. Any suggestions? Thanks.
Edit: i know it is a long piece of code, but should be straight forward (hopefully lol)

Different behaviour between the simulator and the device is often related to incorrect case being used in filenames - the simulator isn't case sensitive, and the device is. Check that you have the correct case used everywhere you reference the plist file.
Alternatively, on the simulator you are able to write directly to the application bundle, but on the device this is not possible and you can only write to certain directories in your application's sandbox, typically the documents directory. You would normally copy a plist to the documents directory on first run, and use that file thereafter.
If I understand right your code you load plist file only in viewDidLoad, but most likely this function called only when you first time load your view. To make it work you should load plist
in viewDidAppear. Something like this:
- (void)viewDidAppear {
NSBundle *bundle = [NSBundle mainBundle];
NSURL *plistURL = [bundle URLForResource:#"CrossfitWOD" withExtension:#"plist"];
//put the contents of the plist into a NSDictionary, and then into names instance variable
NSDictionary *dictionary = [NSDictionary dictionaryWithContentsOfURL:plistURL];
self.names = dictionary;
//take all the keys in the dictionary and make an array out of those key names
self.keys = [self.names allKeys];
for (NSString *nameCheck in keys){
self.details = [names valueForKey:nameCheck];
if ([[self.details valueForKey:#"Type"] isEqualToString:#"The Benchmark Girls"]) {
[buildBenchmarkGirls addObject:nameCheck];
}else if ([[self.details valueForKey:#"Type"] isEqualToString:#"The New Girls"]) {
[buildTheNewGirls addObject:nameCheck];
}else {
[buildHeroes addObject:nameCheck];
}
}
NSString *filePath = [self dataFilePath];
NSMutableDictionary *savedWorkout = [[NSMutableDictionary alloc]initWithContentsOfFile:filePath];
self.savedNames = savedWorkout;
self.savedDFGWorkouts = [[savedWorkout allKeys] sortedArrayUsingSelector:#selector(compare:)];
[self.tableView reloadData];
}
If it works in the Simulator and does not on the phone, almost for sure the problem is a timing issue. Saving files on a real phone takes much longer than on the simulator.
You should do the following:
when you save a file, log it, and log the return code from the save. If the way you save does not provide a return code, use NSFileManager to verify the file is in fact where it should be and even the size of it. This takes time to do but you should do it.
when your table is asking for the number of this and that, log it, and lot what is returned. You may find that that this comes before the files are saved.
It takes time and effort, but if you start logging all relevant things, you can find it. I just spend 6 hours today tracking down a race condition I had thought could never happen, and it was only after looking at a huge trail of messages that I was able to see the problem.
Almost for sure you will see that either file is not saved, its not where you thought it was, or that the phone timing means some events happen later than they do in the Simulator.
i am using this query to get the data by ASC order
select * from list_tbl where cat_id=%d order by names ASC
now my table view shows data based on ASC order
then i used this to get the letters from A to Z on right side
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)help
{
return [[[UILocalizedIndexedCollation currentCollation] sectionTitles] objectAtIndex:help];
}
-(NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView
{
return [[UILocalizedIndexedCollation currentCollation] sectionIndexTitles];
}
- (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index
{
return [[UILocalizedIndexedCollation currentCollation] sectionForSectionIndexTitleAtIndex:index];
}
now my problem is how to divide data based on section header like all A content goes to A and then B till Z and when user click on any alphabet on right side it should goes to that section
// UPDATES ///////////////
-(void)setUpRecordsForIndexing
{
for (NSString * recordName in appDelegate.catLists)//where app.catList contains all the value
{
NSString *firstLetter = ([recordName length] ==0)?miscKey:[[recordName substringToIndex:1]uppercaseString];
/*if(![firstLetter beginsWithCharacterInSet:[NSCharacterSet letterCharacterSet]] || [recordName isEqualToString:#""] || recordName == nil )
firstLetter = miscKey ;
*/
NSMutableArray *indexArray = [IndexedRecords objectForKey:firstLetter];
if (indexArray == nil)
{
indexArray = [[NSMutableArray alloc] init];
[IndexedRecords setObject:indexArray forKey:firstLetter];
[IndexLetters addObject:firstLetter];
[indexArray release];
}
[indexArray addObject:record];// this is not workking
// NSLog(#" index array is %#",indexArray);
}
}
my INDEXRECORD is not showing correct value
i can now divide the section based on ABCD but each sections are having same content , what i am doing wrong
for example: say RecordsArray contains your all the records, now in table view datasource method numberOfSectionsInTableView call one more method to index your all the records like below
-(void)setUpRecordsForIndexing
{
if(IndexedRecords)
{
[IndexedRecords release];
IndexedRecords = nil;
}
if(IndexLetters)
{
[IndexLetters release];
IndexLetters = nil;
}
IndexedRecords = [[NSMutableDictionary alloc] init];
IndexLetters = [[NSMutableArray alloc] init];
NSString *miscKey = #"#";
for (NSString * recordName in RecordsArray)
{
NSString *firstLetter = ([recordName length] ==0)?miscKey:[[recordName substringToIndex:1]uppercaseString];
if(![firstLetter beginsWithCharacterInSet:[NSCharacterSet letterCharacterSet]] || [recordName isEqualToString:#""] || recordName == nil )
firstLetter = miscKey ;
NSMutableArray *indexArray = [mIndexedRecords objectForKey:firstLetter];
if (indexArray == nil)
{
indexArray = [[NSMutableArray alloc] init];
[IndexedRecords setObject:indexArray forKey:firstLetter];
[IndexLetters addObject:firstLetter];
[indexArray release];
}
[indexArray addObject:record];
}
}
and in numberOfSectionsInTableView return the count of IndexLetters. I hope this will solve your problem.
While indexing your records, keep your records in a dictionary say IndexedRecords. Such that, for key "A" set the array of records begin with letter "A". And while populating the table view
[[IndexedRecords objectForKey:[IndexLetters objectAtIndex:indexPath.section]]objectAtIndex:indexPath.row]
IndexLetters is also an array containing your index letters for the current list.
I have a UIViewController (called AdjustViewController) that presents another UIViewController (called SourcePickerViewController) with a UIPickerView modally. I generate instances of the AdjustViewController and they in turn make a SourcePickerViewController. I make an NSDictionary and assign it and an integer to the AdjustViewController and it in turn sets the same properties in the SourcePickerController. This way I can reuse the controllers. The NSDictionary get set up in a UITableViewController that has all the AdjustViewControllers in it.
The problem comes when some of the pickers should have 1 component and some should have 2. The integer that I pass along is called numberOfComponents When I make a picker with numberOfComponents = 1 somehow it's changing to = 2 but I can't see how. I have NSLogs all over the place and I can see it happen as soon as the picker delegate method numberOfComponentsInPickerView is called. It's 1 right before and 2 right after.
There's obviously more code, but I think I have all the important parts. Although if that were true, maybe I'd know where the problem is!
Inside MenuViewController.m
- (void)viewDidLoad {
NSLog(#"ChemicalViewController launched");
self.title = #"Adjust Chemicals";
NSMutableArray *array = [[NSMutableArray alloc] init];
// Chlorine Controller
AdjustViewController *chlorineAdjustViewController = [[AdjustViewController alloc] initWithNibName:#"AdjustViewController" bundle:nil];
chlorineAdjustViewController.title = #"FC - Free Chlorine";
chlorineAdjustViewController.numberOfComponents = 2;
NSLog(#"Generating chlorine source dictionary");
NSDictionary *chlorineSourceDictionary = [self generateChlorineDictionary];
chlorineAdjustViewController.dictionaryOfSources = chlorineSourceDictionary;
[chlorineSourceDictionary release];
[array addObject:chlorineAdjustViewController];
[chlorineAdjustViewController release];
// CYA Controller
AdjustViewController *cyaAdjustViewController = [[AdjustViewController alloc] initWithNibName:#"AdjustViewController" bundle:nil];
cyaAdjustViewController.title = #"CYA - Cyanuric Acid";
cyaAdjustViewController.numberOfComponents = 1;
NSLog(#"Generating cya source dictionary");
NSDictionary *cyaSourceDictionary = [self generateCYADictionary];
cyaAdjustViewController.dictionaryOfSources = cyaSourceDictionary;
[cyaSourceDictionary release];
[array addObject:cyaAdjustViewController];

I didn't look through all of your code; Instead, I'd recommend writing out the properties for numberOfComponents instead of #synthesize'ing them. Just get rid of your #synthesize, and make:
- (int)numberOfComponents {
return m_numberOfComponents;
}
and
- (void)setNumberOfComponents(int aNumberOfComponents) {
m_numberOfComponents = aNumberOfComponents;
}
Then, set a breakpoint in your setNumberOfComponents function, and you should be able to see whenever it's getting called, so you can see what is going on. I hope that helps!
