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];

UIActivityViewController
As shown in above the image , I want custom image and a text in marked places when I share data using UIActivityViewController from my app.
NSString *text = #"Custom Title";
NSURL *url = [NSURL URLWithString: [shareLink stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
UIImage *appIconImage = [UIImage imageNamed: #"IconImage.png"];
NSArray *array = [[NSArray alloc]initWithObjects:appIconImage,text ,url, nil];
UIActivityViewController *controller =
[[UIActivityViewController alloc]
initWithActivityItems:array
applicationActivities:nil];
[controller setValue:#"Custom title" forKey:#"subject"];
controller.excludedActivityTypes = #[UIActivityTypePostToWeibo,
UIActivityTypePrint,
UIActivityTypeAssignToContact,
UIActivityTypeSaveToCameraRoll,
UIActivityTypePostToFlickr,
UIActivityTypePostToVimeo,
UIActivityTypeAirDrop];
Just pass the image urls to UIActivityViewController not the UIImage objects.
NSArray *array = [[NSArray alloc]initWithObjects:appIconImageURL,text ,url, nil];
Hope it helps!
NSURL *url = [NSURL URLWithString:#"file://localhost/Users/admin/Desktop/JSON/vivijson.json"];
NSDictionary *regDict = [[NSDictionary alloc] initWithObjectsAndKeys:self.loginString, #"login",
self.nameString, #"name",
self.lastNameString, #"lastName",
self.emailString, #"email",
self.numberString, #"number", nil];
NSError *error;
NSMutableArray *regMutArray = [[NSMutableArray alloc] init];
[regMutArray addObject:regDict];
NSData *jsonConvRegArrayData = [NSJSONSerialization dataWithJSONObject:regMutArray options:NSJSONWritingPrettyPrinted error:&error];
NSString *jsonRegString = [[NSString alloc] initWithData:jsonConvRegArrayData encoding:NSUTF8StringEncoding];
[jsonConvRegArrayData writeToURL:url atomically:YES];
This method are re-writing JSON, and start it again, but i need to add some to my JSON.
You should first read the exiting JSON into a mutable array using JSONObjectWithData using NSJSONReadingMutableContainers as the reading options. Then add the new array element to the mutable array returned by JSONObjectWithData and then convert it back to an JSON using dataWithJSONObject
Here's the code.
NSURL *url = [NSURL URLWithString:#"file://localhost/Users/Shared/vivijson.json"];
NSDictionary *regDict = [[NSDictionary alloc] initWithObjectsAndKeys:#"self.loginString, #"login",
self.nameString, #"name",
self.lastNameString, #"lastName",
self.emailString, #"email",
self.numberString, #"number", nil];
NSError *error;
NSMutableArray *regMutArray = [[NSMutableArray alloc] init];
[regMutArray addObject:regDict];
NSData *data = [NSData dataWithContentsOfURL:url];
NSMutableArray *array = nil;
if (data)
array = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
if (array == nil)
{
array = [[NSMutableArray alloc] init];
}
[array addObjectsFromArray:regMutArray];
NSData *jsonConvRegArrayData = [NSJSONSerialization dataWithJSONObject:array options:NSJSONWritingPrettyPrinted error:&error];
NSString *jsonRegString = [[NSString alloc] initWithData:jsonConvRegArrayData encoding:NSUTF8StringEncoding];
[jsonRegString writeToURL:url atomically:true encoding:NSUTF8StringEncoding error:nil];
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??
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);
