Hi I have three NSMutableArray. e.g Array - a ,b c. Let say all 3 array have a size of 3.
Would like to ask how do I go about creating 3 section each section contain 3 row (according to no. of array). In each section, the 1st row from a, 2nd row from b, 3rd row from c
1st Section:
[a objectAtIndex:1]
[b objectAtIndex:1]
[c objectAtIndex:1]
2nd Section:
[a objectAtIndex:2]
[b objectAtIndex:2]
[c objectAtIndex:2]
3rd Section:
[a objectAtIndex:3]
[b objectAtIndex:3]
[c objectAtIndex:3]
Thanks!!
create another array and push a,b,c arrays into it
NSArray container =#[a,b,c];
in your tableview cellforRow
use container[indexPath.row][indexPath.section]
You could put all the arrays (a,b,c) to another array which would act as a container. Select elements for from that container like this: container[rowIndex][sectionIndex]. Please also keep in mind setting numbers for each section:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
//should return number of arrays in container
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
//this should return number of elements corresponding to each section
Those methods are a part of UITableViewDataSource Protocol
Try this code
In .h file
#import <UIKit/UIKit.h>
#interface ArrayViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>
{
NSMutableArray *ivContentsList;
}
// Properties
#property (nonatomic, retain) NSMutableArray *contentsList;
.m file
- (void)viewDidLoad
{
[super viewDidLoad];
NSArray *firstSection = [NSArray arrayWithObjects:#"one", #"two", nil];
NSArray *secondSection = [NSArray arrayWithObjects:#"three", #"four", #"five", nil];
NSArray *thirdSection = [NSArray arrayWithObject:#"six"];
NSMutableArray *array = [[NSMutableArray alloc] initWithObjects:firstSection, secondSection, thirdSection, nil];
[self setContentsList:array];
[array release], array = nil;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
NSInteger sections = [[self contentsList] count];
return sections;
}
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
NSArray *sectionContents = [[self contentsList] objectAtIndex:section];
NSInteger rows = [sectionContents count];
return rows;
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSArray *sectionContents = [[self contentsList] objectAtIndex:[indexPath section]];
NSString *contentForThisRow = [sectionContents objectAtIndex:[indexPath row]];
static NSString *CellIdentifier = #"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
[[cell textLabel] setText:contentForThisRow];
return cell;
}
You can try a NSmutableDictionary like:
NSMutableDictionary *myDict = [[NSMutableDictionary alloc] init];
[myDict setObject:Array1 forKey:#"Section1"];
[myDict setObject:Array2 forKey:#"Section2"];
[myDict setObject:Array3 forKey:#"Section3"];
NSLog(#"Result %#",myDict);
Now you can use this dictionary to configure cell.

I can't seem to find too much on this. I'm currently trying to create a swipable delete button that will delete the row that is swiped, and if that row is now empty from the section header it will delete the section header as well. For example, "Bread" is swiped to delete, and there is nothing else under the section header "B". Then this will delete both Bread, and the "B" section header. My code is below.
#interface ChoicesTableViewController () <UITableViewDelegate, UITableViewDataSource>

The basic approach is to see how many rows are in the section for the row being deleted. If the section has two or more rows, simply delete the row as you are doing now. If the section only has one row (the one being deleted), then remove the section from the data model and then delete the section from the table instead of deleting the row.

I am using the following sample code to have the section contents in "Grouped Table View". Showing the contents in "Grouped Table View" is fine.
But, the issue is, it sorts the section content based on alphabetical order, so the order of section header content is not displaying as expected. For example: I want "About" to be shown at the end of section in tableview, but here it is always shows first (because of alphabetical sort does there). How can i display the section content based on the below code without alphabetical sorting. Please advise!

[super viewDidLoad];
NSArray *arrTemp4 = [[NSArray alloc]initWithObjects:#"Quick Logon",#"Stay Logged On", nil];

Thanks in Advance!
Don't use sortedArrayUsingSelector:. Instead, explicitly create the key array in the order that you want. Then, create tableContents using that key array and another array created to hold all of your content arrays (using dictionaryWithObjects:forKeys:).
NSArray *keys = #[ #"About", #"Payment Preferences", #"Profile & Preferences", #"Security" ];
NSArray *values = #[ arrTemp1, arrTemp2, arrTemp3, arrTemp4 ];
self.tableContents = [NSDictionary dictionaryWithObjects:values forKeys:keys];
self.sortedKeys = keys;
Developing a iPAD app, where I'm trying to populate table, This is how i'm doing:
In view did load, I'm creating two dictionary object and adding object as Pdf and Excel.
- (void)viewDidLoad
{
[super viewDidLoad];
arrDocuments = [[NSMutableArray alloc] init];
NSArray *arr1 = [NSArray arrayWithObjects:#"PDF", nil];
NSDictionary *pdf = [NSDictionary dictionaryWithObjects:arr1 forKeys:nil];
NSArray *arr2 = [NSArray arrayWithObjects:#"Excel", nil];
NSDictionary *excel = [NSDictionary dictionaryWithObjects:arr2 forKeys:nil];
[arrDocuments addObject:pdf];
[arrDocuments addObject:excel];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return [arrDocuments count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
//return [arrReceipes count];
NSDictionary *dictionary = [arrDocuments objectAtIndex:section];
NSArray *array = [dictionary objectForKey:[self.sortedKeys objectAtIndex:section]];
return [array count];
}
-(UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = #"MyIdentifier";
UITableView *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell ==nil) {
cell = [[UITableViewCell alloc]initWithFrame:CGRectZero reuseIdentifier:MyIdentifier];
}
return cell;
}
With this implementation I'm not able to see table view.Its going to main method and showing me SIGABRT message.Where I'm going wrong??
While creating NSDictionary, you have passed nil in place of keys array,
NSDictionary *pdf = [NSDictionary dictionaryWithObjects:arr1 forKeys:nil];
You should give proper objects and keys to the dictionary. This method expects objects and keys to be given in an array as you can see in its method signature.
+ (instancetype)dictionaryWithObjects:(NSArray *)objects forKeys:(NSArray *)keys
I am trying to learn how to code a UITableView and is having some problems with the programming of the section.
I have declared 3 arrays with strings and 1 array with the 3 arrays.
firstSection = [NSArray arrayWithObjects:#"Red", #"Blue", nil];
secondSection = [NSArray arrayWithObjects:#"Orange", #"Green", #"Purple", nil];
thirdSection = [NSArray arrayWithObject:#"Yellow"];
array = [[NSMutableArray alloc] initWithObjects:firstSection, secondSection, thirdSection, nil];
To shows the headers
-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{
NSString * title;
title = [NSString stringWithFormat:#"%#" , [array objectAtIndex:section]];
return title;
}
which shows the array itself as the headers
therefore is it possible to actually show the name of the sections using the names of the arrays such as firstSection and secondSection?
In your case, it's better to store your arrays in an NSDictionary. For example, if you declare and synthesize an NSDictionary variable called tableContents and an NSArray called titleOfSections, you can do something like this:
- (void)viewDidLoad {
[super viewDidLoad];
//These will automatically be released. You won't be needing them anymore (You'll be accessing your data through the NSDictionary variable)
NSArray *firstSection = [NSArray arrayWithObjects:#"Red", #"Blue", nil];
NSArray *secondSection = [NSArray arrayWithObjects:#"Orange", #"Green", #"Purple", nil];
NSArray *thirdSection = [NSArray arrayWithObject:#"Yellow"];
//These are the names that will appear in the section header
self.titleOfSections = [NSArray arrayWithObjects:#"Name of your first section",#"Name of your second section",#"Name of your third section", nil];
NSDictionary *temporaryDictionary = [[NSDictionary alloc]initWithObjectsAndKeys:firstSection,#"0",secondSection,#"1",thirdSection,#"2",nil];
self.tableContents = temporaryDictionary;
[temporaryDictionary release];
}
Then in the table view controller methods:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return [self.titleOfSections count];
}
- (NSInteger)tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section {
return [[self.tableContents objectForKey:[NSString stringWithFormat:#"%d",section]] count];
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
//Setting the name of your section
return [self.titleOfSections objectAtIndex:section];
}
Then to access the contents of each array in your cellForRowAtIndexPath method:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *SimpleTableIdentifier = #"SimpleTableIdentifier";
NSArray *arrayForCurrentSection = [self.tableContents objectForKey:[NSString stringWithFormat:#"%d",indexPath.section]];
UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:SimpleTableIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleSubtitle
reuseIdentifier:SimpleTableIdentifier] autorelease];
}
cell.textLabel.text = [arrayForCurrentSection objectAtIndex:indexPath.row];
return cell;
}
can u do like this
NSArray *SectionArray = [[NSArray alloc]initwithArray:[array objectAtIndex:section]];
NSString * title;
title = [NSString stringWithFormat:#"%#" , [SectionArray objectAtIndex:section]];
return title;
I just started learning Xcode, read the book and now trying to implement what I read. The app needs to store certain data in arrays and dictionary, then table view extracts the data by automatically counting number of sections, number of rows and populating table cells with content, assigned to a key word.
Please, see my code, because I've been trying to run the app, but it gives me SIGABRT error. I don't know if new Xcode doesn't declare or call things this way(my book is for iOS3). I tried to find solutions from blogs, youtube, but the app is still not running at this point.
I know that I declared everything correctly in AppDelegate files, etc, because I used someone's sample code of one 1 array. And the table view got populated.
Help me, because something is wrong with my code with NSMutableDictionary and indexPath. Thank you!
