I want to make separate sets based on country name, all custom class objects which contain the USA in one array, India in the array and UK one array, even single object PAK.
Data comes from the server, based on the strContry name I want to make groups.
After adding all objects to "arraydetails", try the below code for achieving the same.
NSArray *countryNames = [[NSOrderedSet orderedSetWithArray:[arrayDetails valueForKey:#"strCountryName"]] array];
for (int i =0; i < [countryNames count]; i++) {
NSMutableArray *countryArray = [[NSMutableArray alloc] init];
for (CustomClass *country in arrayDetails) {
if ([country.strCountryName isEqualToString:[countryNames objectAtIndex:i]]) {
[countryArray addObject:country];
}
}
NSLog(#"Country array[%d] is %#", i, countryArray);
}

I need to sort array (in IOS) like this...
let us suppose that i have an NSMutableArray with : 1,2,3,4,5
i need to build a new array with the last object in the middle and the middle will replace the last : 1.2.5.4.3...
please help:
this is what i doing for now, i got only the 1.2.5 but i not success to put the 4.3 ...
NSMutableArray *arr = [[NSMutableArray alloc] initWithObjects:#1,#2,#3,#4,#5, nil];
int arrCount = (int)arr.count/2;
NSMutableArray *arr2 = [[NSMutableArray alloc] init];
for (int i = 0;i < arr.count; i++) {
if (i < arrCount) {
[arr2 addObject:arr[i]];
}
else{
index = i;
[arr2 addObject:arr.lastObject];
}
}
NSMutableArray *arr = [[NSMutableArray alloc] initWithObjects:#1,#2,#3,#4,#5, nil];

id middleObject = arr2[middleIndex];
[arr2 replaceObjectAtIndex:middleIndex withObject:arr2.lastObject];
[arr2 replaceObjectAtIndex:arr2.count-1 withObject:middleObject];
NSLog(#"%#", arr2);
I am creating a table with multiple columns. In the left column I want to get the indicator name which is stored in a database and I have to check that the indicator id in database and in json (API) matches and then display the name in that column. I have tried some code

Please do help.
Well you are creating new TopicModel object which is empty! You need to use the one which you set in your viewDidLoad: method.
for (int k = 0; k < arrLeft.count; k++) {
if ([(TopicModel *)indicatorName[k] IId] == [arrLeft[k] integerValue]) {
[newArray addObject:[NSString stringWithFormat:#"%#",[(TopicModel *)indicatorName[k] IName]];
}
}
Now I create is as follow (my file.h):
UIImageView *pic1, *pic2, *pic3, *pic4, *pic5, *pic6, *pic7, *pic8, *pic9, *pic10;
Then in my (file.m):
UIImageView *pic1 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#”picName.png”]];
UIImageView *pic2 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#”picName.png”]];
……
UIImageView *pic10 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#”picName.png”]];
I need many instances of UIImageView (number triggered by other factors) of only one in this case picture.
Is there any way to create multiple instances of UIImageView automatically in my file.m, somehow as follow?:
for (int x; (x=10); x++)
{
UIImageView * pic[x] = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"myPic.png"]];
}
This example doesn’t work but I’d like to show what I want to program.
Of course you can - that is what the arrays are for:
NSMutableArray *pics = [NSMutableArray array];
for (int i = 0 ; i != 10 ; i++) {
[pics addObject:[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"myPic.png"]]];
}
In case the name of the picture depends on the index, use NSString's stringWithFormat to produce the name of the picture - for example, you can do it like this:
NSMutableArray *pics = [NSMutableArray array];
for (int i = 0 ; i != 10 ; i++) {
NSString *imgName = [NSString stringWithFormat:#"myPic%d.png"];
[pics addObject:[[UIImageView alloc] initWithImage:[UIImage imageNamed:imgName]]];
}
If the names of images follow a standard pattern you can just loop over the required amount and build the image name dynamically using the index.
If the names of the images do not follow a standard patten you can chuck them in an array and loop over them
NSArray *imageNames = #[
#"alarm.jpg",
#"bell.jpg",
#"car.jpg"
];
NSMutableArray *imageViews = [[NSMutableArray alloc] init];
for (NSString *imageName in imageNames) {
[imagesViews addObject:({
[[UIImageView alloc] initWithImage:[UIImage imageNamed:imageName]];
})];
}
Completely optional - further reading
You could write yourself a simple category that abstracts this looping and collecting the results into a new array. This would allow you to simply write
NSArray *imageNames = #[
#"alarm.jpg",
#"bell.jpg",
#"car.jpg"
];
NSArray *imageViews = [imageNames pas_arrayByMappingWithBlock:^(id obj){
return [[UIImageView alloc] initWithImage:[UIImage imageNamed:imageName]];
}];
The category to do that would look something like this:
#interface NSArray (PASAdditions)
- (NSArray *)pas_arrayByMappingWithBlock:(id (^)(id obj))block
#end
#implementation NSArray (PASAdditions)
- (NSArray *)pas_arrayByMappingWithBlock:(id (^)(id obj))block
{
NSMutableArray *result = [[NSMutableArray alloc] init];
for (id obj in self) {
[result addObject:block(obj)];
}
return [result copy];
}
#end
I'm trying to implement a basic QuickDialog view and the placement of the elements works fine.
But when I select an element the view won't scroll it into view. I thought the library would do this by itself or am I missing something?
Here is my code:
- (id)initWithCoder:(NSCoder *)aDecoder {
if ((self = [super initWithCoder:aDecoder])) {
QRootElement *root = [[QRootElement alloc] init];
root.title = #"";
root.grouped = YES;
self.root = root;
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
QSection *driverSection = [[QSection alloc] initWithTitle:#"xxx"];
QEntryElement *lblDriverSsn = [[QEntryElement alloc] initWithTitle:#"xxx" Value:#""];
lblDriverSsn.key = #"driverSsn";
QSection *vehicleSection = [[QSection alloc] initWithTitle:#"xxx"];
NSArray *component1 = #[#"xxx", #"xxx"];
QPickerElement *EventDescriptionPicker = [[QPickerElement alloc] initWithTitle:#"xxx" items:#[component1] value:#""];
EventDescriptionPicker.key = #"eventDescription";
NSMutableArray *speedValues = [[NSMutableArray alloc]init];
for (int i = 0; i <= 201; i+=5)
{
[speedValues addObject:[NSString stringWithFormat:#"%d%#", i,#" km/h"]];
}
QPickerElement *vehicleSpeed = [[QPickerElement alloc] initWithTitle:#"xxx" items:#[speedValues] value:#""];
self.damageReported = [[QBooleanElement alloc] initWithTitle:#"xxx" BoolValue:NO];
self.damageReported.onImage = [UIImage imageNamed:#"imgOn"];
self.damageReported.offImage = [UIImage imageNamed:#"imgOff"];
self.damageReported.controllerAction = #"showReportNumber:";
QEntryElement *lblReportNumber = [[QEntryElement alloc] initWithTitle:#"xxx" Value:#""];
lblDriverSsn.key = #"reportNumber";
//Sections
[driverSection addElement:lblDriverSsn];
[self.root addSection:driverSection];
[vehicleSection addElement:EventDescriptionPicker];
[vehicleSection addElement:vehicleSpeed];
[vehicleSection addElement:self.damageReported];
[vehicleSection addElement:lblReportNumber];
[self.root addSection:vehicleSection];
}
Am I missing something here?
Thanks in advance
On your initWithCoder: , set the following:
self.resizeWhenKeyboardPresented =YES;
This causes the view controller to listen for keyboard notifications , and adjust the inset accordingly.
