Trying to split the string in to array, but it is giving error "[__NSArrayI componentsSeparatedByString:]: unrecognized selector sent to instance 0x11741b20'". The string contains the value, that comes from first index of array then the string needs to be split and store in array.
This is array value.

It get killed when try to split. Why so, i am not getting. If anyone has faced such situation please guide what is wrong her.
You can split the string into an NSArray like below...
NSString *yourString = #"comment,comment,comment";
NSArray *strArray = [yourString componentsSeparatedByString:#","];
NSLog(#"\n\n Array is ==>> %#",strArray);
"[__NSArrayI componentsSeparatedByString:]:
Your error says you tried to send the above method to NSArray, which doesn't has.
As you want to split the array at index 0. you should probably do as :
NSArray *splitArray=[yourArray[0] componentsSeparatedByString:#","];
Here yourArray is the array that you get from Server.
NSString *strr = [[NSString stringWithFormat:#"%#", [self.mCommArr objectAtIndex:indexVal]];
NSArray *arr2 = [strr componentsSeparatedByString:#","];
I think you are passing str right now, which can be an array (as your error points out).
Let me know the results.

I've got a file with a bunch of string in like so:
item1,01-SR,admin,Missing or broken,undefined, 16/04/2013 18:10:10;
item1,03-SR,admin,In Use,undefined, 16/04/2013 18:10:34;
item1,01-SR,admin,In Use,undefined, 16/04/2013 18:10:45;
item1,02-SR,admin,In Use,undefined, 16/04/2013 18:10:49;
item1,05,admin,In Use,undefined, 16/04/2013 18:10:56;
I'm reading the strings in and then splitting them up so I just get one string at a time. Then I want to split up the string I've got again so each CSV is it's own variable. I've tried this like so (numLines is a count of the number of lines in the file):
while (count1 < numLines) {
NSString *message = [[strings objectAtIndex: count1] copy];
NSMutableArray *items = [[fileContents componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:#";"]] mutableCopy];
NSString *items1 = [[items objectAtIndex: count1] copy];
NSLog(#"items: %#", items1);
NSMutableArray *inditems = [[items1 componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:#","]] mutableCopy];
NSString * item1 = inditems[0];
NSString * bnum1 = inditems[1];
NSString * user1 = inditems[2];
NSString * state1 = inditems[3];
NSString * gender1 = inditems[4];
NSString * tstamp1 = inditems[5];
NSLog(#"item: %#", item1);
NSLog(#"bnum: %#", bnum1);
NSLog(#"user: %#", user1);
NSLog(#"state: %#", state1);
NSLog(#"gender: %#", gender1);
NSLog(#"tstamp: %#", tstamp1);
count1++;
}
Now, this works as far as selecting one line from the file and it puts the first two items into the array and then writes the values of item1 and bnum1 to the log but then it throws an exception for some reason. Now this would usually suggest to me that item 2 doesn't exist in the array so I did a count like so:
NSLog(#"count = %d", [inditems count]);
Which correctly returns 6. I then wanted to check that it could actually read another item from the array so I did:
NSString *tstamp1 = [[inditems lastObject] copy];
Which when logged correctly returns the time stamps like so:
16/04/2013 18:10:10
So I thought "oh at least item 5 works" and tried just getting that item:
while (count1 < numLines) {
NSString *message = [[strings objectAtIndex: count1] copy];
NSMutableArray *items = [[fileContents componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:#";"]] mutableCopy];
NSString *items1 = [[items objectAtIndex: count1] copy];
NSLog(#"items: %#", items1);
NSMutableArray *inditems = [[items1 componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:#","]] mutableCopy];
NSString * item1 = inditems[0];
NSString * bnum1 = inditems[1];
NSString * tstamp1 = inditems[5];
NSLog(#"item: %#", item1);
NSLog(#"bnum: %#", bnum1);
NSLog(#"tstamp: %#", tstamp1);
count1++;
}
But that also throws an exception! I'm probably doing something stupid here, but I would appreciate any help.
Thanks!
My guess is your NSArray *strings is including empty value which is causing your error. You need to check it first and then do your logic.
//path is your file path
NSString* fileContents = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
NSArray *strings = [fileContents componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]];
for (int i = 0; i < [strings count]; i++){
if (![[strings objectAtIndex:i] isEqualToString:#""]){
//Here do your code...
}
}
i am trying to get a random string from database i have tried to convert array in a String but when i click button i only get address can anyone help me how to show that string in my button action?
- (IBAction)randBtn:(id)sender {
SendQuoteVC *svc= [[SendQuoteVC alloc]initWithNibName:#"SendQuoteVC" bundle:nil];
DBHandler *db =[[DBHandler alloc]init];
arr =[db randomQuote];
NSMutableString * show = [[NSMutableString alloc] init];
for (NSObject * obj in arr)
{
[show appendString:[obj description]];
}
NSLog(#"The concatenated string is %#", show);
NSString *rs =[NSString stringWithFormat:#" %#",show];
svc.quote=rs;
[self.navigationController pushViewController:svc animated:YES];
}
and my log message is
2012-12-26 17:02:46.062 SendQuote[2281:c07] QUERY: SELECT * FROM quotes ORDER BY RANDOM() LIMIT 1
2012-12-26 17:02:46.097 SendQuote[2281:c07] txtQuote is (
"<quoteDC: 0xa9a94c0>"
)
2012-12-26 17:02:46.100 SendQuote[2281:c07] rand is (
"<quoteDC: 0xa9a94c0>"
)
i have changed my user entity class to quoteDC class and my Db function is
-(NSMutableArray *)randomQuote{
NSMutableArray *dataArray =[[NSMutableArray alloc]init];
NSString * sqlStr=[NSString stringWithFormat:#"SELECT * FROM quotes ORDER BY RANDOM() LIMIT 1"];
sqlite3_stmt *ReturnStatement = (sqlite3_stmt *) [self getStatement: sqlStr];
while (sqlite3_step(ReturnStatement)==SQLITE_ROW)
{
#try
{
quoteDC *worddc = [[quoteDC alloc] init];
NSString *userid = [NSString stringWithUTF8String:(char *)sqlite3_column_text(ReturnStatement, 0)];
NSString *name = [NSString stringWithUTF8String:(char *)sqlite3_column_text(ReturnStatement, 1)];
worddc.quote_id=[userid integerValue];
worddc.quotes=name;
[dataArray addObject:worddc];
}
#catch (NSException *ept) {
NSLog(#"Exception in %s, Reason: %#", __PRETTY_FUNCTION__, [ept reason]);
}
}
return dataArray;
}
the [db randomQuote] method returns an array of users not strings, you can typecast it to user object than get your desired property out of it!
It seems like your array is an array of objects of some user class rather than array of strings.
Hence the call to
[obj description]
is returning an object instead of a string.
You would need to override the description method in your user class, and return string.
This code makes the issue:
for (NSObject * obj in arr)
{
[show appendString:[obj description]];
}
Because your entity class don't have a property like description.
Instead of this write:
for (quoteDC * obj in arr)
{
[show appendString:[obj quotes]];
}
Try this i think it work for u...
- (IBAction)randBtn:(id)sender {
SendQuoteVC *svc= [[SendQuoteVC alloc]initWithNibName:#"SendQuoteVC" bundle:nil];
DBHandler *db =[[DBHandler alloc]init];
arr =[db randomQuote];
NSString *rs =(NSString *)arr;
svc.quote=rs;
[self.navigationController pushViewController:svc animated:YES];
}
Instead of for (NSObject * obj in arr) use the object that is stored in arr.
I guess it is some DBHandler object. So use
for (DBHandler * dbh in arr){
[show appendString:[dbh thePropertyYouWantToAppend]];
}
I want to add names in a data array only if the name does not previously exist in the data array. When I attempt to print these names, I do get repetitions. Is there a way to solve this?
-(NSMutableArray *)autoComplete
{
NSMutableArray *dataArray = [[NSMutableArray alloc] init];
NSString *url = [NSString stringWithFormat:#"%#45.25,-95.25&limit=100&client_id=Von0J4Bu6INiez5bGby2R&client_secret=50sUjSbg7dba8cQgtpdfr5Ns7wyYTqtmKpUU3khQ",kWSURL];
NSDictionary * returnDict = (NSDictionary *) [self callWebService:url];
if([returnDict objectForKey:#"success"])
{
NSArray *responceArray = [returnDict objectForKey:#"response"];
for (NSDictionary *dict in responceArray) {
placeDC *place = [[placeDC alloc]init];
NSDictionary *placeDict = (NSDictionary *)[dict objectForKey:#"place" ];
NSDictionary *loctionDict =(NSDictionary *)[dict objectForKey:#"loc"];
NSString * name =[placeDict objectForKey:#"name"];
NSString * stateFull =[placeDict objectForKey:#"stateFull"];
NSString * countryFull =[placeDict objectForKey:#"countryFull"];
NSString *latitude =[loctionDict objectForKey:#"lat"];
NSString *longitude = [loctionDict objectForKey:#"long"];
place.placeNmae=name;
place.countryFullName=countryFull;
place.stateFullName=stateFull;
NSLog(#"%# ",stateFull);
place.latitude=[latitude doubleValue];
place.longitude=[longitude doubleValue];
[dataArray addObject:place];
}
}
return dataArray;
}
First Check that is there any response from the Server side or not, to check response use NSLog() or Break Points.
if response is ok then put a the following check your code
if (![dataArray containsObject:#"Some Name"])
{
// add Object
}
You could add the name NSString to an NSSet and check in every cycle whether it contains it or not.
Inside your if you could write something like:
NSArray *responceArray = [returnDict objectForKey:#"response"];
NSSet *names = [[NSSet alloc] init];
for (NSDictionary *dict in responceArray) {
NSDictionary *placeDict = (NSDictionary *)[dict objectForKey:#"place" ];
NSString * name =[placeDict objectForKey:#"name"];
if (![names containsObject:name]) {
[names addObject:name];
placeDC *place = [[placeDC alloc]init];
NSDictionary *loctionDict =(NSDictionary *)[dict objectForKey:#"loc"];
NSString * stateFull =[placeDict objectForKey:#"stateFull"];
NSString * countryFull =[placeDict objectForKey:#"countryFull"];
NSString *latitude =[loctionDict objectForKey:#"lat"];
NSString *longitude = [loctionDict objectForKey:#"long"];
place.placeNmae=name;
place.countryFullName=countryFull;
place.stateFullName=stateFull;
NSLog(#"%# ",stateFull);
place.latitude=[latitude doubleValue];
place.longitude=[longitude doubleValue];
[dataArray addObject:place];
}
}
Hope this helps!
Do one thing, add your dict in another array and search in this array that data already exist or not,
[tempAry addObject: dict];
and before insertion
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"name == %#", name];
NSArray *filteredArray = [tempAry filteredArrayUsingPredicate:predicate];
if ([filteredArray count] == 0)
{
[dataArray addObject:place];
}
else{
//Already exist
}
Why don't you create a separate dictionary, as an ivar or property of you class, for storing our required value, say it as :
NSMutableDictionary *uniqueValueDict=[NSMutableDictionary new];
And keep storing your required value and key as:
[uniqueValueDict setObject:stateFull forKey:uniqueValueDict];
Your work will be done.
This is the easiest solution that i have applied and this should get you going in picking up unique elements out of array.
NSArray * claimedOfferArray = [[NSArray alloc]initWithObjects:#"A",#"B",#"A",#"C",#"B" nil];
NSArray * distinctArray = [[NSArray alloc]init];
distinctArray =[[NSSet setWithArray:claimedOfferArray] allObjects];
This code will also work with NSMutableArray
Let me know if it works for you..:).
I am having an array like fallowing,
NSArray*array = [NSArray arrayWithObjects:#"1.1 something", #"1.2 something else", #"1.3 out of left field", #"1.4 yet another!", nil];
Now,i am having the string like fallowing,
NSString*str = #"1.3";
Now i will send the str .Then it needs to find that str in array and it need to return the index of object where that text found.Means i need index 2 has to come as output.Can anyone share the code please.Thanks in advance.
Here is an example using blocks, notice the method: hasPrefix:
NSArray *array = [NSArray arrayWithObjects:#"1.1 problem1", #"1.2 problem2", #"1.3 problem3", #"1.4 problem4", nil];
NSString *str = #"1.3";
NSUInteger index = [array indexOfObjectPassingTest:
^(id obj, NSUInteger idx, BOOL *stop) {
return [obj hasPrefix:str];
}];
NSLog(#"index: %lu", index);
NSLog output:
index: 2
First a comment,
NSString *str = 1.3;
does not create an NSString object. You should instead have
NSString *str = #"1.3";
To search the NSArray, you will either have to change the string to the exact string in the array or search the NSString as well. For the former, simply do
float num = 1.3;
NSString *str = [NSString stringWithFormat:#"%.1f problem%d",num,(num*10)%10];
[array indexOfObject:str];
You can get fancier using NSPredicates as well.
Try
NSString *searchString = [str stringByAppendingFormat: #" problem%#", [str substringFromIndex: 2]];
NSUInteger index = [array indexOfObject: searchString];
Or (because you somehow like oneliners):
[array indexOfObject: [[array filteredArrayUsingPredicate: [NSPredicate predicateWithFormat: #"SELF beginswith %#", str]] objectAtIndex: 0]];
The simplest way is to enumerate through values of array and check substrings:
NSArray *array = [NSArray arrayWithObjects: #"1.1 something", #"1.2 something else", #"1.3 out of left field", #"1.4 yet another!", nil];
NSString *str = #"1.33";
int i = -1;
int index = -1;
for (NSString *arrayString in array) {
i++;
if ([arrayString rangeOfString: str].location != NSNotFound) {
index = i;
break;
}
}
NSLog(#"Index: %d", index);
Not optimal but will work.
I get a Sigabrt at the NSlog and i have no idea why - any suggestions?
NSString* contentList = [NSString stringWithContentsOfFile:currentFilePath encoding:NSUTF8StringEncoding error:nil];
NSArray* contentArray = [contentList componentsSeparatedByString:#"$$"];
NSLog(#"%#%#",contentList,[contentArray count]);
kunden = [contentArray objectAtIndex:0];
kundenView.text = kunden;
Following Joes suggestions, I now got:
NSString* contentList = [NSString stringWithContentsOfFile:currentFilePath encoding:NSUTF8StringEncoding error:nil];
NSArray* contentArray = [[contentList componentsSeparatedByString:#"$$"] retain];
if ([contentArray count] > 0) {
NSLog(#"%#%#",contentList,[contentArray count]);
kunden = [contentArray objectAtIndex:0];
kundenView.text = kunden;
}
Which gives me an EXC_BAD_ACCESS at the NSLog thing.
I get a Sigabrt at the NSlog
Your NSLog statement is trying to print an integer as if it was an object:
NSLog(#"%#%#",contentList,[contentArray count]);
^
Here!
Replace %# with %d.
You can read more on format specifiers in the String Programming Guide.
You are not checking to make sure you have at least 1 element in your array. Accessing [contentArray objectAtIndex:0] will be an issue if the contentArray is empty.
