Remove duplicate member from CSV file Contant and store in array? - ios
i have an csv file having some duplicate member, i want to delete duplicate and store sort values in an array, i am using following procedure , but its don't give me unique array.
here is my csv value file content

How to convert string to array in iOS?
NSString *strdetails = [NSString stringWithFormat:#"%#",[[products objectAtIndex:i] valueForKey:#"details"]]; NSLog(#"%#",strdetails); When I add on array but it's convert to previous data. But I want array not string.
Here is your code: NSString *strdetails = [NSString stringWithFormat:#"%#",[[products objectAtIndex:i] valueForKey:#"details"]]; NSLog(#"%#",strdetails); I update this code here: NSData *objectData = [strdetails dataUsingEncoding:NSUTF8StringEncoding]; NSDictionary * dict = [NSJSONSerialization JSONObjectWithData:objectData options:NSJSONReadingMutableContainers error:&jsonError]; // Here you are getting dictionary, Now from this you will get array in this way // Print this dict NSLog(#"dict details = %#",dict); NSArray * arrV = dict[#"variants"]; // check your array
NSString *str=#"Hi,I LOVE IOS"; NSArray *arr = [str componentsSeparatedByString:#","]; NSString *strSecond = [arr objectAtIndex:1]; NSMutableArray *arrIOS = [strSecond componentsSeparatedByString:#" "]; NSString *strI = [arrIOS objectAtIndex:0]; NSString *strLOVE = [arrIOS objectAtIndex:1]; NSString *strIOS = [arrIOS objectAtIndex:2]; [arr removeObjectAtIndex:1]; [arr addObject:#","]; [arr addObject:strI]; [arr addObject:strLOVE]; [arr addObject:strIOS];
I guess you are converting jsonString into Array I am using below function to convert my jsonString.
ViewController
public class func JSONParseArray(jsonString: NSString) -> [AnyObject]?{
if let data = jsonString.dataUsingEncoding(NSUTF8StringEncoding){
if let array = (try? NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions(rawValue: 0))) as? [AnyObject] {
return array
}
}
return nil
}
If You Want Specific value from Array:
NSArray *outputArray = [array valueForKey:#"YourKey"];
NSMutableArray parsing csv not working?
I have this code where I use NSMutableArray to parse a csv file. There are no errors that stop me from running the app however the map doesn't display anything.
NSString *csvFilePath = [[NSBundle mainBundle] pathForResource:#"Data2" ofType:#"csv"];
NSString *dataStr = [NSString stringWithContentsOfFile:csvFilePath encoding:NSUTF8StringEncoding error:nil];
NSMutableArray *allLinedStrings = [[NSMutableArray alloc]initWithArray:[dataStr componentsSeparatedByString:#"\r"]];
NSMutableArray *latitude = [[NSMutableArray alloc]init];
NSMutableArray *longitude = [[NSMutableArray alloc]init];
NSMutableArray *description = [[NSMutableArray alloc]init];
NSMutableArray *address = [[NSMutableArray alloc]init];
NSMutableArray *temperature = [[NSMutableArray alloc]init];
NSMutableArray *time = [[NSMutableArray alloc]init];
NSMutableArray *ambient = [[NSMutableArray alloc]init];
NSMutableArray *filteredLocations = [NSMutableArray array];
MKMapPoint* pointArr = malloc(sizeof(MKMapPoint) * filteredLocations.count);
for (int idx = 0; idx < [allLinedStrings count]; idx++)
{
NSMutableArray *infos = [[NSMutableArray alloc]initWithArray:[[allLinedStrings objectAtIndex:idx] componentsSeparatedByString:#","]];
if ([infos count] > 1)
{
[latitude addObject:[infos objectAtIndex:4]];
[longitude addObject:[infos objectAtIndex:5]];
[description addObject:[infos objectAtIndex:0]];
[address addObject:[infos objectAtIndex:10]];
[temperature addObject:[infos objectAtIndex:6]];
[time addObject:[infos objectAtIndex:15]];
[ambient addObject:[infos objectAtIndex:8]];
if([[latitude objectAtIndex:4] isEqualToString:#"NULL"] || [[longitude objectAtIndex:5] isEqualToString:#"NULL"] || [[description objectAtIndex:0] isEqualToString:#"NULL"] || [[address objectAtIndex:10]isEqualToString:#"NULL"] || [[temperature objectAtIndex:6] isEqualToString:#"NULL"] || [[time objectAtIndex:15]isEqualToString:#"NULL"] || [[ambient objectAtIndex:8] isEqualToString:#"NULL"]) {continue;}
CLLocationCoordinate2D coordinate;
coordinate.latitude = [[latitude objectAtIndex:4] doubleValue];
coordinate.longitude = [[longitude objectAtIndex:5] doubleValue];
Location *annotation = [[Location alloc] initWithName:[description objectAtIndex:0] address:[address objectAtIndex:10] temperature:[temperature objectAtIndex:6] time:[time objectAtIndex:15] ambient:[ambient objectAtIndex:8] coordinate:coordinate] ;
[mapview addAnnotation:annotation];
[filteredLocations addObject:annotation];
MKMapPoint point = MKMapPointForCoordinate(coordinate);
pointArr[idx] = point;
}
}
self.routeLine = [MKPolyline polylineWithPoints:pointArr count:filteredLocations.count];
[self.mapview addOverlay:self.routeLine];
free(pointArr);
MKMapRect zoomRect = MKMapRectNull;
for (id <MKAnnotation> annotation in mapview.annotations)
{
MKMapPoint annotationPoint = MKMapPointForCoordinate(annotation.coordinate);
MKMapRect pointRect = MKMapRectMake(annotationPoint.x, annotationPoint.y, 0.1, 0.1);
zoomRect = MKMapRectUnion(zoomRect, pointRect);
}
[mapview setVisibleMapRect:zoomRect animated:YES];
self.mapview.delegate = self;
}
I guess there must be something wrong with how I'm calling the objects or maybe the MKMapPoint but I don't manage to find what's blocking the app from displaying the data. I've tried using both "initWithObjects" and removing "if ([infos count] > 1){" but when ran it crashed showing a breakdown point in "NSMutableArray *latitude = [[NSMutableArray alloc]init];".
Based on your previous questions about this project, you want to do the following at a high level:
Parse a CSV file where each line has coordinate data. Ignore lines that have "null" data. (For the purpose of this answer, let's ignore that one could use a pre-built CSV parser, or use a different format altogether.)
Show annotations for lines with "good" data.
Connect all the annotations with a line.
For requirement 1 (R1), you already know how to load the CSV file, loop through the lines, and identify the lines with "null" data.
For requirement 2 (R2), after some research, you know that you can create and add annotations to the map one at a time and the map doesn't need to know ahead of time how many you will add so that means the first two requirements could be done in the same loop.
For requirement 3 (R3), after some research, you know that to create and add a polyline to the map, you need to know ahead of time how many points will be in the line.
For R1 and R2, you will be looping through the lines of the CSV and identify the non-null lines.
So that means you will know how many points will be in the polyline after the loop that handles R1 and R2. That means the polyline must be created after that loop.
But to create the polyline, you need not just the point count but the coordinates for each point as well.
That means while looping through the lines in the CSV, you need to save the coordinate data somewhere (in the same order it appeared in the CSV).
In Objective-C, a convenient structure that allows you to add data to it without knowing in advance how many objects will be added is an NSMutableArray.
So now we have this very high-level plan:
Loop through the CSV file, ignore lines with null data, create and add annotations, add the line data to an NSMutableArray (NSMA).
Create a polyline using the point data in NSMA, add the polyline to the map.
With this plan, we see we need one NSMutableArray. Notice that in the existing code, you have a Location class that holds (or could hold) all the data from each line of the CSV.
That means we could simply add these Location objects to the NSMA. NSMutableArrays can hold any type of object (they don't have to be just NSStrings).
So here's a slightly more detailed plan:
Initialize an NSMutableArray called filteredLocations (eg. NSMutableArray *filteredLocations = [NSMutableArray array];).
Loop through the CSV file, ignore lines with null data, create a Location object and add as an annotation, add the Location object to filteredLocations (eg. [filteredLocations addObject:annotation];).
Initialize (malloc) a C array to hold the points of the polyline with the point count being the count of filteredLocations.
Loop through filteredLocations, add point from filteredLocations to the C array.
Create and add a polyline to the map.
In this plan note we have two separate loops: The first one is for R1 and R2. The second one is for R3.
If required, I will post sample code that implements this plan.
First, just to explain your latest NSRangeException error, it is happening on this line:
if([[latitude objectAtIndex:4] isEqualToString:#"NULL"] || ...
because you've declared latitude as an array and the first time the if executes in the loop, latitude only has one object (a few lines above this if you do [latitude addObject:...). The index of an array starts at zero so the bounds of an array with one object are zero to zero hence the error message saying index 4 beyond bounds [0 .. 0].
There are many other issues with the rest of the code.
There is not enough room in this answer to explain in detail.
I urge you, if possible, to stop, step back and re-start with a much simpler project or tutorials and, most importantly, learn the absolute basics of programming in general.
Here is an example of code that should work based on your sample data:
-(void)viewDidLoad
{
[super viewDidLoad];
self.mapview.delegate = self;
NSString *csvFilePath = [[NSBundle mainBundle] pathForResource:#"Data2" ofType:#"csv"];
NSString *dataStr = [NSString stringWithContentsOfFile:csvFilePath encoding:NSUTF8StringEncoding error:nil];
NSArray *allLinedStrings = [dataStr componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]];
NSMutableArray *filteredLocations = [NSMutableArray array];
for (int idx = 0; idx < [allLinedStrings count]; idx++)
{
NSArray *infos = [[allLinedStrings objectAtIndex:idx] componentsSeparatedByString:#","];
if ([infos count] > 15)
{
NSString *latitude = [infos objectAtIndex:4];
NSString *longitude = [infos objectAtIndex:5];
NSString *description = [infos objectAtIndex:0];
NSString *address = [infos objectAtIndex:10];
NSString *temperature = [infos objectAtIndex:6];
NSString *time = [infos objectAtIndex:15];
NSString *ambient = [infos objectAtIndex:8];
if([latitude isEqualToString:#"NULL"]
|| [longitude isEqualToString:#"NULL"]
|| [description isEqualToString:#"NULL"]
|| [address isEqualToString:#"NULL"]
|| [temperature isEqualToString:#"NULL"]
|| [time isEqualToString:#"NULL"]
|| [ambient isEqualToString:#"NULL"])
{
continue;
}
CLLocationCoordinate2D coordinate;
coordinate.latitude = [latitude doubleValue];
coordinate.longitude = [longitude doubleValue];
Location *annotation = [[Location alloc] initWithName:description
address:address
temperature:temperature
time:time
ambient:ambient
coordinate:coordinate];
[mapview addAnnotation:annotation];
[filteredLocations addObject:annotation];
}
}
MKMapPoint* pointArr = malloc(sizeof(MKMapPoint) * filteredLocations.count);
for (int flIndex = 0; flIndex < filteredLocations.count; flIndex++)
{
Location *location = [filteredLocations objectAtIndex:flIndex];
MKMapPoint point = MKMapPointForCoordinate(location.coordinate);
pointArr[flIndex] = point;
}
self.routeLine = [MKPolyline polylineWithPoints:pointArr count:filteredLocations.count];
[self.mapview addOverlay:self.routeLine];
free(pointArr);
[self.mapview showAnnotations:self.mapview.annotations animated:YES];
}
Put multiple arrays in Dictionary
I am parsing a CSV file multiple times with for loop, here I need to store these arrays one by one dictionary. There are very less questions in stack about adding NSArray to NSDictionary. I am parsing CSV with below code but I strucked at storing in NSDictionary, The program is terminating and showing warning at assigning string to dictionary
for (i=0; i<=57; i++) {
NSString *keysString = [csvArray objectAtIndex:i];
NSArray *keysArray = [keysString componentsSeparatedByString:#","];
NSLog(#"Serail No %d %#",i,keysArray);
NSString *string = [NSString stringWithFormat:#"%d", i];
NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithObjects: keysArray forKeys: string];
}
NSMutableDictionary *dict = [[NSMutableDictionary alloc]init];
for (i=0; i<=57; i++) {
NSString *keysString = [csvArray objectAtIndex:i];
NSArray *keysArray = [keysString componentsSeparatedByString:#","];
NSString *key = [NSString stringWithFormat:#"serial%d",i];
[dict setObject:keysArray forKey:key];
}
To get back data from dictionary,
NSArray *array = [dict valueForKey:#"serial24"];//to get array 24.
If I understand you correctly, you want to add the arrays to a dictionary, with the key being the string value of integer i ? What you need to do is allocate the dictionary outside your loop -
NSMutableDictionary *dict=[NSMutableDictionary new];
for (i=0; i<=57; i++) {
NSString *keysString = [csvArray objectAtIndex:i];
NSArray *keysArray = [keysString componentsSeparatedByString:#","];
NSLog(#"Serial No %d %#",i,keysArray);
NSString *string = [NSString stringWithFormat:#"%d", i];
dict[string]=keysArray;
}
I am not sure why you would want to do this, because this is basically an array. You could simply do -
NSMutableArray *outputArray=[NSMutableArray new];
for (NSString *keysString in csvArray) {
NSArray *keysArray = [keysString componentsSeparatedByString:#","];
[outputArray addObject:keysArray];
}
Create a Custom Formatted Dictionary Array from CSV File of Data
I've created an iPhone app that has a dictionary array of locations (lat,long,point). I created the array by manually entering each value.
myLocationArray = #[
#{
kStation : #"1",
kLatitude : #( 41.656467),
kLongitude : #(-81.277963)
},
#{
kStation : #"2",
kLatitude : #(41.657118),
kLongitude : #(-81.276545)
},
#{
kStation : #"3",
kLatitude : #(41.658493),
kLongitude : #(-81.273542)
},
...
This is good and works but now I want to create this array programmatically by getting the data from a .CSV file. I have a .CSV file (TestCSV.csv) that looks like this.
41.656467,-81.277963,27200

Specifically, I'd like to create myLocationArray (with formatting as shown) by reading straight from the TestCSV.csv. I'm not familiar with the code to achieve this and would really appreciate some direction.
Also, would it be any different or easier if the data was provided via text file instead of csv?
Try
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"Locations" ofType:#"csv"];
NSString *csvString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
NSArray *locations = [csvString componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]];
NSMutableArray *locationsArray = [NSMutableArray array];
for (NSString * location in locations)
{
NSArray *components = [location componentsSeparatedByString:#","];
double latitude = [components[0] doubleValue];
double longitude = [components[1] doubleValue];
NSString *station = components[2];
NSDictionary *dict = #{#"kLatitude": #(latitude),
#"kLongitude": #(longitude),
#"kStation": station};
[locationsArray addObject:dict];
}
CSV File
Answer inspired from
csv file IS a plain-text file. To achive what you want you can use NSScanner and NSString componentsSeparatedByString: Everything else is really simple.
Answer provided by Anupdas. Cheers!
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"Locations" ofType:#"csv"];
NSString *csvString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
NSArray *locations = [csvString componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]];
NSMutableArray *locationsArray = [NSMutableArray array];
for (NSString * location in locations)
{
NSArray *components = [location componentsSeparatedByString:#","];
double latitude = [components[0] doubleValue];
double longitude = [components[1] doubleValue];
NSString *station = components[2];
NSDictionary *dict = #{#"kLatitude": #(latitude),
#"kLongitude": #(longitude),
#"kStation": station};
[locationsArray addObject:dict];
}
IOS: problem with nsarray layout
In this code I read a file txt: this txt file have information in this way:
one#two#three#four#five;one#two#three#four#five;
- (void) readFile{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:#"File.txt"];
NSString *fileString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:NULL];
if (!fileString) {
NSLog(#"Error reading file.");
}
NSMutableArray *itemDB = [[fileString componentsSeparatedByString:#";"] mutableCopy];
[itemDB removeLastObject];
NSMutableArray *returnArray = [[NSMutableArray alloc] init];
for (int i = 0; i<[itemDB count]; i++) {
NSArray *datiItemDB = [[itemDB objectAtIndex:i] componentsSeparatedByString:#"#"];
[returnArray addObject: datiItemDB];
}
one = [[NSMutableArray alloc] initWithArray:(NSArray*)returnArray];
[returnArray release];
}
the result of nslog of this array is
2011-07-04 10:01:16.847 Project[254:707] array one:(
(
"(\n 0,\n 1,\n 12,\n \"2011-07-04 08:00:41 +0000\",\n \"2011-07-15 00:00:00 +0000\",\n \"\",\n 0,\n 0,\n (\n ),\n \"\"\n)"
)
)
but I want that the result of nslog is
2011-07-04 09:52:07.281 Project[230:707] array one:(
(
0,
1,
1,
"2011-07-04 07:45:15 +0000",
"2011-07-04 07:45:15 +0000",
"",
0,
0,
(
),
""
)
)
Why I have "/n" symbols, and how can I remove it from my array?
Do you just want to put the first part of the text file in an array? I think you are overcomplicating the problem. What about something like this: NSString *inputString = #"one#two#three#four#five;one1#two2#three3#four4#five5;"; NSArray *arrayFromInputString = [inputString componentsSeparatedByString:#";"]; NSArray *component1 = [[arrayFromInputString objectAtIndex:0] componentsSeparatedByString:#"#"]; NSLog(#"1: %#", [component1 description]); NSArray *component2 = [[arrayFromInputString objectAtIndex:1] componentsSeparatedByString:#"#"]; NSLog(#"2: %#", [component2 description]); If you run that, the output is [777:207] 1: ( one, two, three, four, five ) [777:207] 2: ( one1, two2, three3, four4, five5 ) Is this what you wanted? If not, can you try to explain better?
