In my application i am using picker control,
I want to get the data from array to my picker view,
Array comes like this,
PickerArray:(
{
CustEmail = test#test.com;
CustFirstName = ABC;
CustID = 1;
CustLastName = Test;
CustPhoneNo = 12345;
}
My picker has one component,
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
NSString *title;
title = [[PickerArray objectAtIndex:row]valueForKey:#"CustFirstName"];
NSLog(#"title:%#",title);
return title;
}
with this I am getting just one value If i want to get CustFirstName and Email in one row of picker component.
Like ABC test#test.com;
Please any one suggest how can i do that?
You can use stringWithFormat: to construct composite strings, like this:
title = [NSString stringWithFormat:#"%# %#"
, [[PickerArray objectAtIndex:row]valueForKey:#"CustFirstName"]
, [[PickerArray objectAtIndex:row]valueForKey:#"CustEmail"]
];
Compose string according to requirement:
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
NSString *title = [NSString stringWithFormat:#"%# %#",[[PickerArray objectAtIndex:row]valueForKey:#"CustFirstName"],[[PickerArray objectAtIndex:row]valueForKey:#"CustEmail"]];
NSLog(#"title:%#",title);
return title;
}
Try
title = [NSString stringWithFormat:#"%# %#",[[PickerArray objectAtIndex:row]valueForKey:#"CustFirstName"],[[PickerArray objectAtIndex:row]valueForKey:#"CustEmail"]];

i have an UIPickerView and i want it to have 2 columns filled with items from my arrays, but i cant figure out how, there is my arrays:
-(void)fillingStandartWeightArray{
if (!standartWeightArray){
for (int i=25; i<150 ;i++){
NSString *weightString;
weightString = [NSString stringWithFormat:#"%d kg", i];
[standartWeightArray addObject:weightString];
NSLog(#"%#", weightString);
}
}
}
-(void)fillingStandartHeightArray{
if (!standartHeightArray){
for (int i=85; i<250; i++){
NSString *heightString;
heightString = [NSString stringWithFormat:#"%d cm", i];
[standartHeightArray addObject:heightString];
NSLog(#"%#", heightString);
}
}
}
To be more specific i don't know how to "tell" UIPickerView to fill one of it wheel with one array, and other one with other array. I tried this:
-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component{
if (component == 0){
return [standartWeightArray count];
} else {
return [standartHeightArray count];
}
}
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView{
return 2;
}
-(NSString*)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component{
if (component == 0)
return [standartWeightArray objectAtIndex:row];
else if (component == 1)
return [standartHeightArray objectAtIndex:row];
}
And i did call functions in viewDidLoad sections:
- (void)viewDidLoad
{
[super viewDidLoad];
[self fillingStandartWeightArray];
[self fillingStandartHeightArray];
NSLog(#"%#", standartWeightArray);
}
But that's not working.
Your datasource/delegate methods are perfect.
Take care of following things
1) Allocating standartHeightArray and standartWeightArray objects properly. Allocate array objects as below if you are not doing already.
-(void)fillingStandartWeightArray{
if (!standartWeightArray){
// Allocate the array
standartWeightArray = [NSMutableArray new];
for (int i=25; i<150 ;i++){
NSString *weightString;
weightString = [NSString stringWithFormat:#"%d kg", i];
[standartWeightArray addObject:weightString];
NSLog(#"%#", weightString);
}
}
}
-(void)fillingStandartHeightArray{
if (!standartHeightArray){
// Allocate the array
standartHeightArray = [NSMutableArray new];
for (int i=85; i<250; i++){
NSString *heightString;
heightString = [NSString stringWithFormat:#"%d cm", i];
[standartHeightArray addObject:heightString];
NSLog(#"%#", heightString);
}
}
}
2) Connect the delegate/datasource properties of picker properly. You can do it in interface builder or in code (in viewDidLoad)
Sure looks like you are setting everything up correctly to me.
But make sure you set the UIPickerView delegate and data source to the same object / class (ViewController?) where your PickerView data source methods live.
You can set this either in Xcode's Interface Builder, or at "viewDidLoad:" time programmatically (if you have your picker view set to an IBOutlet).
My numberOfComponentsInPickerView :
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
return 3;
}
My numberOfRowsInComponent :
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
if (component == 0)
return 100;
if (component == 1)
return 100;
if (component == 2)
return 100;
return 0;
}
My titleForRow like this:
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
if (component == 0)
return [NSString stringWithFormat:#"%d", row];
if (component == 1)
return [NSString stringWithFormat:#"%d", row];
if (component == 2)
return [NSString stringWithFormat:#"%d", row];
return 0;
}
my didSelectRow like this
after edited like Paras Joshi's said :
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
int year = [picker selectedRowInComponent:0];
int month = [picker selectedRowInComponent:1];
int day = [picker selectedRowInComponent:2];
if(viewPicker.tag == 1)
labelDate1.text = [year stringByAppendingFormat:#" : %d : %d", month, day];
else
labelDate2.text = [year stringByAppendingFormat:#" : %d : %d", month, day];
}
it still gives me error " bad receiver type 'int' " and i still don't get it how to fix it. how my label get data from titleForRow?
both input for year month and day all are number only (from 0 to 99) so that i wrote -> return [NSString stringWithFormat:#"%d", row];
i dont put data for my pickerview at - (void)viewDidLoad because i want my labelDate1 or labelDate2 got data from pickerview. is there any possible my label get data from pickerview like i wrote above? or must i write my data at - (void)viewDidLoad ?
for any help, thank you for watching my question.
In your program you are appending string to an integer that is the issue.
This code makes the issue. Because year is an integer.
labelDate1.text = [year stringByAppendingFormat:#" : %d : %d", month, day];
Please check with this code.
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
int year = [picker selectedRowInComponent:0];
int month = [picker selectedRowInComponent:1];
int day = [picker selectedRowInComponent:2];
NSString *date = #"";
if(viewPicker.tag == 1)
labelDate1.text = [date stringByAppendingFormat:#" %d : %d : %d",year, month, day];
else
labelDate2.text = [date stringByAppendingFormat:#"%d : %d : %d", year, month, day];
}
Did you set the UIPickerView's delegate?I mean, did your pickerView:didSelectRow:inComponent get called?
Hello #Piyo Piyo your
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
method is totally wrong, you are assigning NSInteger to NSString. Thats why you are getting en error. You should use NSArray for putting data in picker view row and picking data from here. Here i'm going to make a small sample code.
This is your viewController.h file...
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController<UIPickerViewDelegate, UIPickerViewDataSource>
{
UIPickerView *myPickerView;
NSMutableArray *arrayYear;
NSMutableArray *arrayMonth;
NSMutableArray *arrayDay;
UILabel *lblDay;
UILabel *lblMonth;
UILabel *lblYear;
}
#end
there are three array which will contain the data for day, month and year respectively and three UILabel for showing the data. and obviously one pickerview.
Now come to on your viewController.m part.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
// UIPickerView declaration by coding
myPickerView = [[UIPickerView alloc]initWithFrame:CGRectMake(0.0, 0.0, 320.0, 216.0)];
myPickerView.delegate = self;
myPickerView.showsSelectionIndicator = YES;
[self.view addSubview:myPickerView];
// add some day number to day array
arrayDay = [[NSMutableArray alloc]init];
for(int i=1;i<6;i++)
{
NSString *string = [NSString stringWithFormat:#"%d",i];
[arrayDay addObject:string];
}
// add some month string to month array
arrayMonth = [[NSMutableArray alloc]init];
[arrayMonth addObject:#"June"];
[arrayMonth addObject:#"July"];
[arrayMonth addObject:#"August"];
[arrayMonth addObject:#"September"];
[arrayMonth addObject:#"October"];
// add some year number to year array
arrayYear = [[NSMutableArray alloc]init];
for(int i=2006;i<2011;i++)
{
NSString *string = [NSString stringWithFormat:#"%d",i];
[arrayYear addObject:string];
}
//set initially text to day label
lblDay = [[UILabel alloc]initWithFrame:CGRectMake(10.0, 250.0, 90.0, 50.0)];
[lblDay setText:[arrayDay objectAtIndex:0]];
[self.view addSubview:lblDay];
//set initially text to month label
lblMonth = [[UILabel alloc]initWithFrame:CGRectMake(110.0, 250.0, 90.0, 50.0)];
[lblMonth setText:[arrayMonth objectAtIndex:0]];
[self.view addSubview:lblMonth];
//set initially text to year label
lblYear = [[UILabel alloc]initWithFrame:CGRectMake(210.0, 250.0, 90.0, 50.0)];
[lblYear setText:[arrayYear objectAtIndex:0]];
[self.view addSubview:lblYear];
//set initially selection to each component of UIPickerView
[myPickerView selectRow:1 inComponent:0 animated:NO];
[myPickerView selectRow:1 inComponent:1 animated:NO];
[myPickerView selectRow:1 inComponent:2 animated:NO];
}
//here you are returning the number of component, which are 3 in this case
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView;
{
return 3;
}
//this is your didSelectRow method and here you are assigning a new text to
//label accordingly to if condition
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
if(component == 0)
{
lblDay.text = [arrayDay objectAtIndex:row];
}
if(component == 1)
{
lblMonth.text = [arrayMonth objectAtIndex:row];
}
if(component == 2)
{
lblYear.text = [arrayYear objectAtIndex:row];
}
}
//this is your numberOf row in component in this case each component have 5
//rows thats why i wrote only return 5; here you can put if condition here for
//returning different rows for each component
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component;
{
return 5;
}
// and this is showing title on rows
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component;
{
if (component == 0)
return [arrayDay objectAtIndex:row];
else if (component == 1)
return [arrayMonth objectAtIndex:row];
else if (component == 2)
return [arrayYear objectAtIndex:row];
else
return 0;
}
I hope this tutorial will help you. Thank you!
I wrote this code for the first UIPickerView
- (void)viewDidLoad
NSURL *url = [NSURL URLWithString:
#"http://localhost:8080/Data/resources/converter.country/"];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDelegate:self];
[request startAsynchronous];
// countrys = [[UIPickerView alloc] init];
countrys.delegate = self;
countrys.dataSource = self;
countrys.showsSelectionIndicator = YES;
countryField.inputView=countrys;
- (NSString*)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
NSString *codeCity;
codeCity=[countriesArray objectAtIndex:row];
return codeCity;
}
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
return 1;
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {
return [countriesCodeArray count];
}
And then i wanted to make another UIPickerView with cities . I wrote this
citys.delegate = self;
citys.dataSource = self;
citys.showsSelectionIndicator = YES;
cityField.inputView=citys;
But when i click on it i have countries list . How should i change the datasource ? And how to use the default function of the UIPickerView, like numberOfComponentsInPickerView , numberOfRowsInComponent: ... with the second UIPickerView ?
You can assign tag to your pickerviews and then can check these tags in datasource/delegate methods
citysPickerview.tag = 2
otherPickerview.tag = 1
// then you can check for these tags in pickerview datasource/delegate methods like this -
- (NSString*)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
NSString *title;
if (pickerview.tag == 1) // this is otherPickerview
{
title=[countriesArray objectAtIndex:row]; // your logic to get title for otherpickerview
}
else if (pickerview.tag == 2) // this is citysPickerview
{
title=[countriesArray objectAtIndex:row]; // your logic to get title for cityspickerview
}
return title;
}
You should follow this same mechanism in your all datasource/delegate code :)
What you could do is set tag for the 2 UIPickerView, like so - [countryPicker setTag:1], use these tags to distinguish between the 2 picker views.
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
return 1;
}
- (NSInteger)pickerView:(UIPickerView *)pickerView
numberOfRowsInComponent:(NSInteger)component
{
if([pickerView tag] == 1)
return [countryNames count];
else
return [cityNames count];
}
- (NSString *)pickerView:(UIPickerView *)pickerView
titleForRow:(NSInteger)row
forComponent:(NSInteger)component
{
if([pickerView tag] == 1)
return [countryNames objectAtIndex:row];
else
return [cityNames count];
}
For a simpler solution, just compare the pickerView pointer. That way you save the additional complexity and maintenance of using tags.
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
NSInteger numberOfRows = 0;
if (pickerView == countrys) {
numberOfRows = [countriesCodeArray count];
}
else if (pickerView == citys) {
numberOfRows = [citysCodeArray count];
}
return numberOfRows;
}
Note: This answer is based on giuseppe's comment.
I need your advice in solving this issue:
I am parsing a XML File and puting the results in NSMutableDictionarys which I put in NSMutableArray:
The NSMutableArray with the Dictionarys looks like this:
Res: (
{
adresse = "Wielandg 36";
email = "office#tierarzt-riegelnegg.at";
latitude = "47.063065712289";
longitude = "15.439759954196";
ordiname = "Kleintierpraxis Jakomini Dipl Tzt Riegelnegg Gerfried";
ort = Graz;
plz = 8010;
tel = "+43316830438";
tierarztid = 3;
web = "http://www.tierarzt-riegelnegg.at";
},
{
adresse = "Rechbauerstr 3";
email = "glantschnig#kleintierambulatorium.at";
fax = "+43316321156";
latitude = "47.070320493663";
longitude = "15.448505434137";
ordiname = "KLEINTIERAMBULATORIUM - Dr. Simon Glantschnig";
ort = Graz;
plz = 8010;
tel = "+43316321156";
tierarztid = 2;
web = "http://www.kleintierambulatorium.at";
},
{
adresse = "Humboldtstr 7";
latitude = "47.079379100630";
longitude = "15.440064023548";
ordiname = "Bernhart Barbara Dr";
ort = Graz;
plz = 8010;
tel = "+43316684912";
tierarztid = 4;
}
Well this part works really fine! Now I put "ordiname" inside a UITableView, and when the User clicks the name, I am opening a "DetailView" where I want to show the results of the dictionary inside an UITableView or CustomCells - NSLog for this works fine - I can see the whole selected dictionary in the DetailView. Presenting in the TableView or CustomCells has to be done dynamically, as not all of the possible entries have to be filled (for example: Fax is not mandatory).
How can I achieve this? The order of the NSMutableDictionary is always the same...
Thanks for any help and advice!
BR,
Stefan
All you need is to have the DetailView adopt the UITableViewDataSource protocol and add the following methods,
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [myDictionary count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *name = [[myDictionary allKeys] objectAtIndex: indexPath.row];
NSString *value = [myDictionary objectForKey:name];
UITableViewCell *cell = [table dequeReusableCellWithItentifier:#"MyCell"];
if(!cell) {
//create cell
}
//set the name and value
cell.textLabel.text = [NSString stringWithFormat:#"%#:%#", name, value];
return cell;
}
I need help regarding UIPickerView, in my application i have to display UIPickerView with available countries . If any body has already implemented country picker please share the code.
Thanks
Here's a countries plist that I created for this purpose:
https://gist.github.com/vilcsak/c205dfd153a3e465f47e
Implementation should be pretty straightforward, but here's a bit of our code:
- (id)init {
if ((self = [super init])) {
self.countries = [NSArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"Countries" ofType:#"plist"]];
}
return self;
}
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
self.currentCountry = [[self.countries objectAtIndex:row] objectForKey:#"code"];
self.countryLabel.text = [[self.countries objectAtIndex:row] objectForKey:#"name"];
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {
return self.countries.count;
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
return [[self.countries objectAtIndex:row] objectForKey:#"name"];
}
You can get a list of available country names like this:
self.countryArray = [NSMutableArray new];
for (NSString *countryCode in [NSLocale ISOCountryCodes]) {
NSString *country = [[NSLocale systemLocale] displayNameForKey:NSLocaleCountryCode value:countryCode];
[self.countryArray addObject: country];
}
and here are some UIPicker delegate methods:
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
self.countryLabel.text = [self.countryArray objectAtIndex:row];
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {
return self.countryArray.count;
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
return [self.countryArray objectAtIndex:row];
}
You can take the countries.plist from the following like and use that for ur picker input
http://code.google.com/p/reviewscraper/source/browse/trunk/Countries.plist?spec=svn22&r=22
Make an array of available country and use this array in these delgate methods and data source methods
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
--> return value at index of array
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
number of elements in array
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
return 1;
here is the link to the blog post regarding country list data picker in a popover.
