Ok, so I would like to create an NSDictionary, but the pointer should be followed by the value of an NSString that has been put in by the user. Is this possible? I imagine it would be something along the lines of this...
someNSString = _someTextField.text;
NSDictionary * {someNSString} = [NSDictionary dictionaryWithObjectsAndKeys:
[NSNumber numberWithInt:someUnimportantVariable], #"someUnimportantKey",...nil]
Thanks in advance, I realize that this is either completely not possible or there is a pretty simple solution. Either way, I'm sorry if I wasted your time.
you could try creating a "dictionary of dictionaries". something to the effect of:
someNSString = _someTextField.text;
NSDictionary *myDictionary = [[NSDictionary alloc] init];
[myDictionary setObject:[NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:someUnimportantVariable], #"someUnimportantKey",...nil] forKey:someNSString];
and if you wanted to get back that dictionary
NSDictionary someNSStringDictionary = [myDictionary objectForKey:someNSString];
let me know if it helps in any way.

I am trying to show the User different Phone Numbers on Apple Watch and he clicks on one than phone call alert should appear. I'll do it like this but the Alert is just dismissed without call action:
NSMutableArray *tempArray = [[NSMutableArray alloc] initWithCapacity:0];
WKExtension *myExt = [WKExtension sharedExtension];
for (NSString *phone in arr) {
NSString *tel = [NSString stringWithFormat:#"tel:%#",phone];
WKAlertAction *act = [WKAlertAction actionWithTitle:tel style:WKAlertActionStyleDefault handler:^(void){
[myExt openSystemURL:[NSURL URLWithString:phone1]];
}];
[tempArray addObject:act];
}
NSString *titleMessage = #"Call";
NSString *textMessage = #"Please select the number you want to call.";
NSString *cancel = #"Cancel";
WKAlertAction *act = [WKAlertAction actionWithTitle:cancel style:WKAlertActionStyleDestructive handler:^(void){
}];
[tempArray addObject:act];
[self presentAlertControllerWithTitle:titleMessage message:textMessage preferredStyle:WKAlertControllerStyleAlert actions:tempArray];
Buttons are shown as expected and the Handler is also called with the correct Phone Number. But it does not openSystemURL. Does somebody know why and how to fix? Thanks!
I think you forgot to add "tel" scheme ,Use below code :
[WKAlertAction actionWithTitle:#"tel" style:WKAlertActionStyleDefault handler:^(void){
[[WKExtension sharedExtension]openSystemURL:[NSURL URLWithString:[NSString stringWithFormat:#"tel:%#",#"YOUR NUMBER"]]];
}];

I have an application where i am storing japanese text in a coredata sqlite database. Populating the data seems to work ok (as far as I can tell), but when I search on any string field it returns no records. If I search on one of my integer fields it does.
The string data is unicode (ie, Japanese characters), so my question is will core data not work with Unicode? Seems unlikely. Does something special have to be done so a search (fetch) will work?
Code to populate the data looks like this:
WordProgress *newWordProgress = [NSEntityDescription insertNewObjectForEntityForName:#"WordProgress" inManagedObjectContext:progressContext];
newWordProgress.kanji = kanji;
newWordProgress.kanji = kana;
newWordProgress.senseIndex = [NSNumber numberWithInt:senseIndex];
newWordProgress.skillType = [NSNumber numberWithInt:skillType];
newWordProgress.leitnerDeck = leitnerDeck;
newWordProgress.dateLastShown = lastShownDate;
Code to test my fetch, looks like this:
NSPredicate *pred = [NSPredicate predicateWithFormat:#"kanji = %#", #"彼"];
NSFetchRequest *testRequest = [[NSFetchRequest alloc] init];
[testRequest setPredicate:pred];
[testRequest setEntity:[NSEntityDescription entityForName:#"WordProgress" inManagedObjectContext:progressContext]];
NSArray *results = [progressContext executeFetchRequest:testRequest error:&error];
But returns no records, when I know that records were populated.
Just tried this too, and even this seems to fail. I'm sure I must be doing something fundamentally wrong:
WordProgress *newWordProgress = [NSEntityDescription insertNewObjectForEntityForName:#"WordProgress" inManagedObjectContext:progressContext];
newWordProgress.kanji = #"彼";
newWordProgress.kanji = kana;
newWordProgress.senseIndex = [NSNumber numberWithInt:senseIndex];
newWordProgress.skillType = [NSNumber numberWithInt:skillType];
newWordProgress.leitnerDeck = leitnerDeck;
newWordProgress.dateLastShown = lastShownDate;
NSPredicate *pred = [NSPredicate predicateWithFormat:#"kanji = %#", #"彼"];
NSFetchRequest *testRequest = [[NSFetchRequest alloc] init];
[testRequest setPredicate:pred];
[testRequest setEntity:[NSEntityDescription entityForName:#"WordProgress" inManagedObjectContext:progressContext]];
NSArray *results = [progressContext executeFetchRequest:testRequest error:&error];
It's not a Unicode problem, it's an NSPredicate error that would affect any string. You have:
NSPredicate *pred = [NSPredicate predicateWithFormat:#"kanji = '%#'", #"彼"];
The single quotes in there are the problem. You're creating a predicate that looks for a literal %# in the data. The single quotes prevent substituting the #"彼" for the %#. Take the single quotes out and it should work as expected:
NSPredicate *pred = [NSPredicate predicateWithFormat:#"kanji = %#", #"彼"];
My god, I'm completely retarded, sorry. Doing some more playing I saw the line...
newWordProgress.kanji = kanji;
newWordProgress.kanji = kana;
Doh! It was completely overwriting my key field. It should have read...
newWordProgress.kanji = kanji;
newWordProgress.kana = kana;
Thanks for the replies, guys. Sorry!
Thanks in advance!
I'm wondering if it's possible to convert HTML code stored in a NSString to a NSData to parse later.
I'm reading from a BBDD the HTML code and saving it into a NSString.
NSString *htmlString =#"<html><body><p>introduccion</p><p>introducción</p></body></html>";
I want to use:
NSData *nsData = [[NSData alloc] initWithContentsOfURL:url];
But instead of initWithContentsOfURL i have to use the htmlString because I have the code stored in a BBDD and I am accessing it and storing the code to a NSString
Thanks!
Why dont you use standard methods to convert NSString to NSData like this:
NSData* data = [htmlString dataUsingEncoding:NSUTF8StringEncoding];
I have some html formatted text in my "subject.details", I add some more html formatting on the front and back. Giving me a "detailsStringForDisplay" NSString.
I convert this string to an NSData.
Set up a dictionary, which only contains one element to say that the document type is HTML.
Then finally set an attributedText using the data and the dictionary.
NSString *fontDetailsHTML = #"<div style=\"font-size:17px; text-family:Georgia; \">";
NSString *detailsString = subject.details;
NSString *endFontDetailsHTML = #"</div>";
NSString *detailsStringForDisplay = [NSString stringWithFormat:#"%#%#%#",fontDetailsHTML,detailsString,endFontDetailsHTML];
NSData *labelTextData = [detailsStringForDisplay dataUsingEncoding:NSUnicodeStringEncoding allowLossyConversion:true];
NSDictionary *attributesForText = [[NSDictionary alloc]initWithObjectsAndKeys:NSHTMLTextDocumentType,NSDocumentTypeDocumentAttribute , nil];
self.detailDescriptionLabel.attributedText = [[NSAttributedString alloc]initWithData:labelTextData options:attributesForText documentAttributes:nil error:nil];
I want to do mock for TnSettings, yes, it works if code by the following method, the problem is that we need to do write mock code for each case, if we only mock once then execute more than one case, then the second will report exception. I use the latest OCMock V2.01.
My question is that why OCMock has such restriction? Or is it my fault not to use it correctly?
Any idea or discussion will be appreciated, thanks in advance.
- (void) testFormattedDistanceValueWithMeters {
mockSettings = [OCMockObject mockForClass:[TnSettings class]];
mockClientModel = [TnClientModel createMockClientModel];
[[[mockClientModel expect] andReturn:mockSettings] settings];
[[[mockSettings expect] andReturn:[NSNumber numberWithInt:0]] preferencesGeneralUnits];
NSNumber *meters = [NSNumber numberWithDouble:0.9];
distance = [NSString formattedDistanceValueWithMeters:meters];
STAssertEqualObjects(distance, #"0.9", #"testformattedEndTimeForTimeInSeconds failed");
//------------- Another case -----------------
mockSettings = [OCMockObject mockForClass:[TnSettings class]];
mockClientModel = [TnClientModel createMockClientModel];
[[[mockClientModel expect] andReturn:mockSettings] settings];
[[[mockSettings expect] andReturn:[NSNumber numberWithInt:0]] preferencesGeneralUnits];
meters = [NSNumber numberWithDouble:100.9];
distance = [NSString formattedDistanceValueWithMeters:meters];
STAssertEqualObjects(distance, #"101", #"testformattedEndTimeForTimeInSeconds failed");
}
Not sure I understand your question or your code fully. I suspect that you stumbled over the difference between expect and stub, though.
Is this what you had in mind?
- (void) testFormattedDistanceValueWithMeters {
mockSettings = [OCMockObject mockForClass:[TnSettings class]];
mockClientModel = [TnClientModel createMockClientModel];
[[[mockClientModel stub] andReturn:mockSettings] settings];
[[[mockSettings stub] andReturn:[NSNumber numberWithInt:0]] preferencesGeneralUnits];
NSNumber *meters = [NSNumber numberWithDouble:0.9];
distance = [NSString formattedDistanceValueWithMeters:meters];
STAssertEqualObjects(distance, #"0.9", #"testformattedEndTimeForTimeInSeconds failed");
meters = [NSNumber numberWithDouble:100.9];
distance = [NSString formattedDistanceValueWithMeters:meters];
STAssertEqualObjects(distance, #"101", #"testformattedEndTimeForTimeInSeconds failed");
}
I'm trying to find out how to go through my CoreData information and find objects that have a createdAt (part of my object as an NSDate) that is within a NSTimeInterval. How do I set this up?
I've looked on the documentation at:
http://developer.apple.com/documentation/Cocoa/Conceptual/Predicates/predicates.html
But I'm not finding anything there.
Do I need to create two time stamps and use SQL's BETWEEN?
Any help would be wonderful.
First of all, it doesn't make sense to check if an NSDate is within an NSTimeInterval, because NSTimeInterval just specifies a length of time, not its location. Instead, you want to use two separate NSDates specifying the beginning and end of your intervals.
Here's what it would look like (beginningTime and endTime are NSDates).
NSFetchRequest *request = [[NSFetchRequest alloc] init];
request.entity = [NSEntityDescription entityForName:#"YourEntityName" inManagedObjectContext:yourContext];
NSPredicate *beginningPredicate = [NSPredicate predicateWithFormat:#"createdAt >= %#", beginningTime];
NSPredicate *endPredicate = [NSPredicate predicateWithFormat:#"createdAt <= %#", endTime];
request.predicate = [NSCompoundPredicate andPredicateWithSubpredicates:[NSArray arrayWithObjects:beginningPredicate, endPredicate, nil]];
NSArray *results = [yourContext executeFetchRequest:request error:NULL];
