I create a dictionary with this data:
NSString *fileContentMap = [[NSString alloc] initWithContentsOfFile:MapPath];
SBJsonParser *parserMap = [[SBJsonParser alloc] init];
NSDictionary *dataMap = (NSDictionary *) [parserMap objectWithString:fileContentMap error:nil];
NSArray *MaparrayLongitude = [dataMap objectForKey:#"longitude"];
NSArray *MaparrayLatitude = [dataMap objectForKey:#"latitude"];
NSDictionary* DictionaryMap = [NSDictionary dictionaryWithObjects:MaparrayLatitude forKeys:MaparrayLongitude];
..then I read it with this code:
NSArray *allKeys2 = [DictionaryMap allKeys];
NSString *key2 = [allKeys2 objectAtIndex:i];
NSObject *obj2 = [DictionaryMap objectForKey:key2];
...but the keys are not ordered, and I want them to be ordered in the original order. How can I do this??

I can't save my new data to plist file for some reason. This is code I have been using for saving data:
-(void)saveData:(NSMutableDictionary *)dictionaryData toFile:(NSString *)filename {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDir = [paths objectAtIndex:0];
NSString *path = [docDir stringByAppendingPathComponent:filename];
NSMutableArray *data = [[NSMutableArray alloc] initWithContentsOfFile:path];
[data addObject:dictionaryData];
[data writeToFile:filename atomically:YES];
}
this is code I used to copy file from bundle to app directory in case if it is not there :
-(NSMutableArray *)loadFromFile:(NSString *)filename {
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDir = [paths objectAtIndex:0];
NSString *path = [docDir stringByAppendingPathComponent:filename];
NSFileManager *fileMgr = [NSFileManager defaultManager];
if(![fileMgr fileExistsAtPath:path]) {
NSArray *fileArray = [filename componentsSeparatedByString:#"."];
NSString *name = [fileArray objectAtIndex:0];
NSString *ext = [fileArray objectAtIndex:1];
NSString *bundle = [[NSBundle mainBundle] pathForResource:name ofType:ext];
[fileMgr copyItemAtPath:bundle toPath:path error:&error];
}
NSMutableArray *data = [[NSMutableArray alloc] initWithContentsOfFile:path];
return data;
}
For some reason I can't save new data to plist file. When I try to add new NSMutableDictionary object to my plist file (with saveData:toFile: method) and than reload my array variable with the plist file data - new object is not there. Am I doing something wrong?
this is how I load plist file :
#property (nonatomic, strong) NSMutableArray *modules;
#property (nonatomic, strong) NSMutableDictionary *module;
- (void)viewDidLoad {
[super viewDidLoad];
self.modules = [self loadFromFile:#"ModulesList.plist"];
self.module = [self.modules objectAtIndex:0];
for (int i = 0; i < self.modules.count; i++ ) {
NSLog(#"Modules array from plist file, module at index %i : %#",i, [self.modules objectAtIndex:i]);
}
than for testing purpose I have this code to add new module object:
- (IBAction)leftButton:(id)sender {
NSString *mytitle = [[NSString alloc] initWithFormat:#"my title"];
NSString *myauthor = [[NSString alloc] initWithFormat:#"my author2"];
NSUInteger myean = 22023423;
NSString *mytitle2 = [[NSString alloc] initWithFormat:#"my title 2"];
NSString *myauthor2 = [[NSString alloc] initWithFormat:#"my author2"];
NSUInteger myean2 = 29032432;
NSString *mytitle3 = [[NSString alloc] initWithFormat:#"my title 3"];
NSString *myauthor3 = [[NSString alloc] initWithFormat:#"my author 3"];
NSUInteger myean3 = 21023423;
NSMutableDictionary *mybook = [[NSMutableDictionary alloc] init];
NSMutableDictionary *mybook2 = [[NSMutableDictionary alloc] init];
NSMutableDictionary *mybook3 = [[NSMutableDictionary alloc] init];
[mybook setObject:mytitle forKey:#"title"];
[mybook setObject:myauthor forKey:#"author"];
[mybook setObject:[NSNumber numberWithInteger:myean] forKey:#"ean"];
[mybook2 setObject:mytitle2 forKey:#"title"];
[mybook2 setObject:myauthor2 forKey:#"author"];
[mybook2 setObject:[NSNumber numberWithInteger:myean2] forKey:#"ean"];
[mybook3 setObject:mytitle3 forKey:#"title"];
[mybook3 setObject:myauthor3 forKey:#"author"];
[mybook3 setObject:[NSNumber numberWithInteger:myean3] forKey:#"ean"];
NSMutableArray *mybooks = [[NSMutableArray alloc] init];
[mybooks addObject:mybook];
[mybooks addObject:mybook2];
[mybooks addObject:mybook3];
[self.module setObject:mybooks forKey:#"books"];
[self.modules addObject:self.module];
for (int i = 0; i < self.modules.count; i++ ) {
NSLog(#"Modules array after add operation, module at index: %i: %#",i, [self.modules objectAtIndex:i]);
}
[self saveData:self.module toFile:#"ModulesList.plist"];
}
than when I will reload my self.modules array from plist with button action, my new data is not there:
- (IBAction)reload:(id)sender {
self.modules = [self loadFromFile:#"ModulesList.plist"];
for (int i = 0; i < self.modules.count; i++ ) {
NSLog(#"RELOAD: Modules array from plist file, module at index %i : %#",i,[self.modules objectAtIndex:i]);
}
}
this is screenshot of my plist file : http://dl.dropbox.com/u/49076351/Screen%20Shot%202013-02-27%20at%2016.27.45.png
Webservice sends me JSON that looks like that:
[
{"key":"key1","value":"value1"},
{"key":"key2","value":"value2"},
{"key":"key3","value":"value3"}
]
How should I set up RestKit mapping to get the following NSDictionary?
#{ #"key1" : #"value1", #"key2" : #"value2", #"key3": #"value3" }
This may help you, try this.
NSDictionary *dict1 = [[NSMutableDictionary alloc] init];
NSArray *arr = [[NSArray alloc] initWithArray:<Parse the array here from RESTkit>];
for (int i = 0;i < [arr count], i++)
{
NSDictionary *dict = [arr objectAtIndex:i];
NSString *key = [dict objectForKey:#"key"];
NSString *value = [dict objectForKey:#"value"];
[dict1 setObject:value forKey:key];
}
NSLog(#" Dictionary %#", dict1);
[dict1 release];
I'm using UIActivityViewController to share some text from my app. I can send the text to messages, email, copy etc but I can't send it to print.
I see UIActivityTypePrint takes a datatype of NSData. How can I create UIActivityViewController to take my string as both a string and NSData so that the view has the print option available?
NSString *textToShare = self.note.note;
NSArray *itemsToShare = [[NSArray alloc] initWithObjects:textToShare, nil];
shareVC = [[UIActivityViewController alloc] initWithActivityItems:itemsToShare applicationActivities:nil];
shareVC.excludedActivityTypes = [[NSArray alloc] initWithObjects:UIActivityTypeSaveToCameraRoll, UIActivityTypePostToWeibo, nil];
Got it. It doesn't take NSData directly, it takes UISimpleTextPrintFormatter.
NSString *textToShare = self.note.note;
UISimpleTextPrintFormatter *printData = [[UISimpleTextPrintFormatter alloc]
initWithText:textToShare];
NSArray *itemsToShare = [[NSArray alloc] initWithObjects:textToShare,printData, nil];
shareVC = [[UIActivityViewController alloc] initWithActivityItems:itemsToShare applicationActivities:nil];
shareVC.excludedActivityTypes = [[NSArray alloc] initWithObjects:UIActivityTypeSaveToCameraRoll, UIActivityTypePostToWeibo, nil];
Add another item of NSData type in the array itemsToShare
NSString *textToShare = self.note.note;
NSData* data = [textToShare dataUsingEncoding:NSUTF8StringEncoding];
NSArray *itemsToShare = [[NSArray alloc] initWithObjects:textToShare,data, nil];
shareVC = [[UIActivityViewController alloc] initWithActivityItems:itemsToShare applicationActivities:nil];
shareVC.excludedActivityTypes = [[NSArray alloc] initWithObjects:UIActivityTypeSaveToCameraRoll, UIActivityTypePostToWeibo, nil];
OR
use dictionary to send item
NSString *textToShare = self.note.note;
NSData* data = [textToShare dataUsingEncoding:NSUTF8StringEncoding];
NSMutableDictionary *dictionary = [NSMutableDictionary dictionary];
[dictionary setObject:textToShare forKey:#"shareString"];
[dictionary setObject:data forKey:#"shareData"];
NSArray *itemsToShare = [[NSArray alloc] initWithObjects:dictionary, nil];
[dictionary release];
shareVC = [[UIActivityViewController alloc] initWithActivityItems:itemsToShare applicationActivities:nil];
shareVC.excludedActivityTypes = [[NSArray alloc] initWithObjects:UIActivityTypeSaveToCameraRoll, UIActivityTypePostToWeibo, nil];
Its only outputting one set for NSMutableDictionary not both. I want to create an JSON request using NSMutableDictionary (JSONRepresentation).
// My code
NSArray *keysEndpoint = [NSArray arrayWithObjects:#"ID", #"Name", #"EndpointType", nil];
NSArray *objectEndpoint = [NSArray arrayWithObjects:#"622", #"Brand", #"0", nil];
NSArray *keysEndpoint1 = [NSArray arrayWithObjects:#"ID", #"Name", #"EndpointType", nil];
NSArray *objectEndpoint1 = [NSArray arrayWithObjects:#"595", #"CK-05052011", #"1", nil];
NSMutableArray *keys1 = [[NSMutableArray alloc] initWithCapacity:0];
NSMutableArray *objects1 = [[NSMutableArray alloc] initWithCapacity:0];
[keys1 addObjectsFromArray:keysEndpoint];
[keys1 addObjectsFromArray:keysEndpoint1];
NSLog(#"Key Dic: %#", keys1);
[objects1 addObjectsFromArray:objectEndpoint];
[objects1 addObjectsFromArray:objectEndpoint1];
NSLog(#"Obje Dic: %#", objects1);
NSMutableDictionary *testMut = [NSMutableDictionary dictionaryWithObjects:objects1 forKeys:keys1];
NSLog(#"Test Dic: %#", testMut);
Output is am getting is this:
Test Dic: {
EndpointType = 1;
ID = 595;
Name = "CK-05052011";
}
Expexted output i want is :
Test Dic: {
EndpointType = 1;
ID = 595;
Name = "CK-05052011";
}
{
EndpointType = 0;
ID = 622;
Name = "Brand";
}
For a dictionary, adding the same keys twice will override the first set of keys. You should have a NSMutableArray of NSMutableDictionary
NSArray *keysEndpoint = [NSArray arrayWithObjects:#"ID", #"Name", #"EndpointType", nil];
NSArray *objectEndpoint = [NSArray arrayWithObjects:#"622", #"Brand", #"0", nil];
NSArray *keysEndpoint1 = [NSArray arrayWithObjects:#"ID", #"Name", #"EndpointType", nil];
NSArray *objectEndpoint1 = [NSArray arrayWithObjects:#"595", #"CK-05052011", #"1", nil];
NSMutableDictionary *testMut = [NSMutableDictionary dictionaryWithObjects:objectsEndpoint forKeys:keysEndpoint];
NSMutableDictionary *testMut1 = [NSMutableDictionary dictionaryWithObjects:objectsEndpoint1 forKeys:keysEndpoint1];
NSMutableArray * dictArray = [NSMutableArray arrayWithObjects:testMut,testMut1,nil];
NSLog(#"Test DictArray: %#", dictArray);
I wonder if it is possible to fill rangeOfString objects of a NSArray. Because I have a long list of objects for after rangeOfString:
NSArray biglist´s count is higher than list´s count.
I want to filter away the objects from the small list of the main list.
Please tell me if this is not clear.
My codes below:
NSArray *biglist = [[NSArray alloc] initWithArray:
[[NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"mainlist" ofType:#"txt"]
encoding:NSUTF8StringEncoding error:NULL] componentsSeparatedByString:#"\n"]];
NSArray *list = [[NSArray alloc] initWithArray:
[[NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"smalllist" ofType:#"txt"]
encoding:NSUTF8StringEncoding error:NULL] componentsSeparatedByString:#"\n"]];
for (NSString *listword in list);
NSMutableArray *wordlist = [[NSMutableArray alloc] init];
NSMutableArray *worindex = [[NSMutableArray alloc] init];
NSMutableIndexSet *mindexes = [[NSMutableIndexSet alloc] init];
NSMutableDictionary *mutdic = [[NSMutableDictionary alloc] init];
NSMutableArray *mutarray = [[NSMutableArray alloc] init];
for (NSString *s in mainlist)
{
NSRange ran = [s rangeOfString:listword];
if (ran.location !=NSNotFound)
{
//my codes here
}
}
EDIT:
I think I can solve this by writing
int i;
for (i = 0; i<[list count]; i++)
{
NSString *same = [list objectAtIndex:i];
NSLog (#"listword: %#", same);
}
But I am not sure where to place it, inside the for loop s in mainlist or outside.
EDIT: This for loop works inside the main for loop.
EDIT:
Tried these codes, but it doesnt work somehow..
NSArray *list = [[NSArray alloc] initWithArray:
[[NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"small" ofType:#"txt"]
encoding:NSUTF8StringEncoding error:NULL] componentsSeparatedByString:#"\n"]];
NSArray *mainlist = [[NSArray alloc] initWithArray:
[[NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"mainlist" ofType:#"txt"]
encoding:NSUTF8StringEncoding error:NULL] componentsSeparatedByString:#"\n"]];
NSMutableArray *large = [NSMutableArray arrayWithArray:mainlist];
NSArray *newlarge;
for (NSString *listword in list)
{
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"(SELF beginswith[c] %#)",listword];
newlarge = [large filteredArrayUsingPredicate:predicate];
}
NSLog (#"large: %#", newlarge);
NSLog (#"finished!");
"I want to filter away the objects from the small list of the main list."
If I understand correctly, you want to remove an array of items from another array. You don't want to do that much work and allocations inside an n^2 loop.
This removes an array of items from another array. Depending on how large your array is you may need to optimize further but this works:
NSArray *small = [NSArray arrayWithObjects:#"three", #"two", nil];
NSMutableArray *large = [NSMutableArray arrayWithObjects:#"one", #"two", #"three", #"four", nil];
[large removeObjectsInArray:small];
// print
for (NSString *current in large)
{
NSLog(#"item: %#", current);
}
This outputs:
2011-10-13 08:39:21.176 Craplet[5235:707] item: one
2011-10-13 08:39:21.178 Craplet[5235:707] item: four
I figured it out by myself and solved this :)
It works almost perfectly.
My codes:
NSArray *big = [[NSArray alloc] initWithObjects:#"hello ->mache", #"heisann hoppsann ->hiya", #"nei men ->da", #"however ->what", #"may ->april", #"mai ->maj", nil];
NSArray *small = [[NSArray alloc] initWithObjects: #"heisann ", #"nei men ", #"however ", #"mai", nil];
NSMutableArray *smallwithh = [[NSMutableArray alloc] init];
NSMutableIndexSet *mindexes = [[NSMutableIndexSet alloc] init];
for (NSString *same in small)
{
NSLog (#"listword: %#", same);
for (NSString *s in big)
{
NSRange ran = [s rangeOfString:same];
if (ran.location !=NSNotFound)
{
[smallwithh addObject:s];
NSUInteger ind = [big indexOfObject:s];
[mindexes addIndex:ind];
}
}
}
NSLog (#"smallwith: %#", smallwithh);
[smallwithh release];
NSMutableArray *newWords =[NSMutableArray arrayWithArray: big];
[newWords removeObjectsAtIndexes: mindexes];
[big release];
[small release];
NSLog (#"newWords: %#", newWords);
