I need to convert this "5?8?519223cef9cee4df999436c5e8f3e96a?EVAL_TIME?60?2013-03-21" string into dictionary. Separated by "?"
Dictionary would be some thing like
{
sometext1 = "5",
sometext2 = "8",
sometext3 = "519223cef9cee4df999436c5e8f3e96a",
sometext4 = "EVAL_TIME",
sometext5 = "60",
sometext6 = "2013-03-21"
}
Thank you .
Break the string to smaller strings and loop for them.
This is the way
NSArray *objects = [inputString componentsSeparatedByString:#"?"];
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
int i = 1;
for (NSString *str in objects)
{
[dict setObject:str forKey:[NSString stringWithFormat:#"sometext%d", i++]];
}
Try
NSString *string = #"5?8?3519223cef9cee4df999436c5e8f3e96a?EVAL_TIME?60?2013-03-21";
NSArray *stringComponents = [string componentsSeparatedByString:#"?"];
//This is very risky, your code is at the mercy of the input string
NSArray *keys = #[#"cid",#"avid",#"sid",#"TLicense",#"LLicense",#"date"];
NSMutableDictionary *dictionary = [NSMutableDictionary dictionary];
for (int idx = 0; idx<[stringComponents count]; idx++) {
NSString *value = stringComponents[idx];
NSString *key = keys[idx];
[dictionary setObject:value forKey:key];
}
EDIT: More optimized
NSString *string = #"5?8?3519223cef9cee4df999436c5e8f3e96a?EVAL_TIME?60?2013-03-21";
NSArray *stringComponents = [string componentsSeparatedByString:#"?"];
NSArray *keys = #[#"cid",#"avid",#"sid",#"TLicense",#"LLicense",#"date"];
NSMutableDictionary *dictionary = [NSMutableDictionary dictionaryWithObjects:stringComponents forKeys:keys];
first separate the string into several arrays by '?'.
then add the string in you dictionary.
sth like this:
NSString *str = #"5?8?519223cef9cee4df999436c5e8f3e96a?EVAL_TIME?60?2013-03-21";
NSArray *valueArray = [str componentsSeparatedByString:#"?"];
NSMutableArray *keyArray = [[NSMutableArray alloc] init];
for (int i = 0; i <[valueArray count]; i ++) {
[keyArray addObject:[NSString stringWithFormat:#"sometext%d",i+1]];
}
NSDictionary *dic = [[NSDictionary alloc] initWithObjects:valueArray forKeys:keyArray];
For the future: If you were to store your data in JSON format (closer to what you have anyway), it'll be much easier to deal with and transfer between systems. You can easily read it...using NSJSONSerialization

I have an array and I want to split that array into 3 parts or 3 arrays.
1st array contains -> AppName
2nd array contains -> Description
3rd array contains -> Icon
Here is the json array I want to split,
Deviceinfo = (
{
Appname = App;
Description = "This is test app";
Icon = "57.png";
}
);
}
Here is my code for this,
NSMutableArray *firstArray = [NSMutableArray array];
NSMutableArray *secondArray = [NSMutableArray array];
NSMutableArray *thirdArray = [NSMutableArray array];
for (int i = 0; i < [json count]; i++) {
NSArray *tempArray = [[json objectAtIndex:i]componentsSeparatedByString:#""];
[firstArray addObject:[tempArray objectAtIndex:0]];
[secondArray addObject:[tempArray objectAtIndex:1]];
if ([tempArray count] == 3)
{
[thirdArray addObject:[tempArray objectAtIndex:2]];
}
}
NSLog(#"yourArray: %#\nfirst: %#\nsecond: %#\nthird: %#", json, firstArray, secondArray, thirdArray);
I observe a crash in the code at this line,
NSArray *tempArray = [[json objectAtIndex:i]componentsSeparatedByString:#""];
I don't understand what is going wrong here. Any pointers to solve this issue?
I think you can using below code i hope this help's you :-
NSMutableArray *firstArray = [NSMutableArray array];
NSMutableArray *secondArray = [NSMutableArray array];
NSMutableArray *thirdArray = [NSMutableArray array];
NSDictionary *jsonArray = [NSJSONSerialization JSONObjectWithData: jsonResponse options: NSJSONReadingMutableContainers error: &e];
//here is first i load with Dicutionary bcz if into your Json you have may be multiple Dictuionary so you then you can load purticular dictionary as bellow line
EDIT
NSArray * responseArr = jsonArray[#"Deviceinfo"];
firstArray = [responseArr valueForKey:#"Appname"];
secondArray = [responseArr valueForKey:#"Description"];
thirdArray = [responseArr valueForKey:#"Icon"];
if you have multiple Deviceinfo dictionary in to your Json then you could use For loop
// NSArray * responseArr = jsonArray[#"Deviceinfo"];
// for (NSDictionary *dict in responseArr) {
// [firstArray addObject:[dict valueForKey:#"Appname"];
// [secondArray addObject:[dict valueForKey:#"Description"];
// [thirdArray addObject:[dict valueForKey:#"Icon"];
// }
NSMutableArray *firstArray = [[NSMutableArray alloc]init];
NSMutableArray *secondArray = [[NSMutableArray alloc]init];
NSMutableArray *thirdArray = [[NSMutableArray alloc]init];
NSDictionary *list =[NSJSONSerialization JSONObjectWithData:data
options:kNilOptions error:&error];
NSArray * tempArray = jsonArray[#"Deviceinfo"];
for (NSDictionary *list in tempArray)
{
[firstArray addObject:[list objectForKey:#"Appname"];
[secondArray addObject:[list objectForKey:#"Description"];
[thirdArray addObject:[list objectForKey:#"Icon"];
}
Then try
NSLog(#"yourArray: %#\nfirst: %#\nsecond: %#\nthird: %#", tempArray, firstArray, secondArray, thirdArray);
NSData *jsonData = [NSData dataWithContentsOfURL:[NSURL URLWithString:#"http://url.to.your.json"]];
NSArray *jsonObjects = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:nil];
NSMutableArray *appNameArray = [NSMutableArray array];
NSMutableArray *discriptionArray = [NSMutableArray array];
NSMutableArray *iconArray = [NSMutableArray array];
for(NSDictionary *dictionary in jsonObjects)
{
[appNameArray adddObject:[dictionary valueForKey:#"Appname"];
[appNameArray adddObject:[dictionary valueForKey:#"Description"];
[appNameArray adddObject:[dictionary valueForKey:#"Icon"];
}
I want to auto-incrementing a key and at to a NSMutableDictionary.
I tried to do it but it wasn't work :
NSMutableDictionary *array = [[NSMutableDictionary alloc] init];
int testAutoIndex = 0;
[array setObject:[NSNumber numberWithInt:testAutoIndex++] forKey:#"index"];
[array release];
Thanks :)
Use this:
NSMutableDictionary *array = [[NSMutableDictionary alloc] init];
int testAutoIndex = 0;
[array setObject:[NSNumber numberWithInt:++testAutoIndex] forKey:#"index"];
[array release];
If you want to create a dictionary with say N entries, then it is possible to do using the code
int N = 100; // or what ever number you want
NSArray *arrayOfObjectsYouWantToPumpIntoDictionary = ....;
NSMutableDictionary *mutableDictionary = [NSMutableDictionary dictionaryWithCapacity:100];
for(int i=0;i<N;i++){
NSString *key = [NSString stringWithFormat:#"%d"i];
[mutableDictionary setObject:[arrayOfObjectsYouWantToPumpIntoDictionary objectAtIndex:i] forKey:];
}
// Later some where else if you want to retrieve object with key of x (x can be 1, or 2 or what ever value), you can do
objectToBeRetrieved = [mutableDictionary objectForKey:[NSString stringWithFormat:#"%d",x];

I dont know man, Data is exactly printed in the console, but crashing at UILABEL(temperatureLabel). Help me out, thanks in advance
if you look at the error you are getting it is telling you that the object return for the key temperature is not a NSString or NSDictionary but a NSNumber.
Give this a try:
-(void) httpDataDidFinishLoadingWithData:(NSData *)theData {
m_activityLoaded=NO;
temp=[[NSString alloc] initWithData:[dataLoader httpData]
encoding:NSUTF8StringEncoding];
NSLog(#"TEMP IS TEMP %#", temp);
NSDictionary *dict = [[temp JSONValue] objectForKey:#"location"];
NSDictionary *dict1 = [[temp JSONValue] objectForKey:#"wind"];
NSDictionary *dict2 = [dict1 objectForKey:#"direction"];
NSDictionary *dict3 = [[temp JSONValue] objectForKey:#"atmosphere"];
NSDictionary *dict4 = [[temp JSONValue] objectForKey:#"condition"];
NSDictionary *dict5 = [dict4 objectForKey:#"text"];
NSDictionary *dict6 = [dict4 objectForKey:#"code"];
NSNumber *temperature = [dict4 objectForKey:#"temperature"];
temperatureLabel.text = [NSString stringWithFormat:#"%#", temperature];
}
You might want to look at NSNumberFormatter for formatter the temperature with something like: °F or °C.
Are you sure that your object is of NSString class?
Try putting in something like:
if([[dict4 objectForKey:#"temperature"] isKindOfClass:[NSString class]])
NSLog(#"lalala");
If it does not get logged to the console it means that your object is not an NSString and you could try something like:
temperatureLabel.text = [NSString stringWithFormat:#"%#", [dict4 objectForKey:#"temperature"]];
You should change the %# according to the kind of object you have stored in your dictionnary.
Your dictionary contains an NSNumber instance and you are assigning that to a property of type NSString. The crash message is your tip off there. Use stringValue or some other way to get the number's data into string form.
How to convert string to array in objective C. i.e,I have a string,
NSString *str = #"Hi,How r u";
This should be converted into an array *NSMutableArray arr , where in
arr[0] = "Hi"
arr[1] = ","
arr[2] = "How"
arr[3] = "r"
arr[4] = "u"
Can anybody help with the idea to crack this thing.
NSString *str=#"Hi,How r u";
NSArray *arr = [str componentsSeparatedByString:#","];
NSString *strSecond = [arr objectAtIndex:1];
NSMutableArray *arrSecond = [strSecond componentsSeparatedByString:#" "];
NSString *strHow = [arr objectAtIndex:0];
NSString *strAre = [arr objectAtIndex:1];
NSString *strYou = [arr objectAtIndex:2];
[arr removeObjectAtIndex:1];
[arr addObject:#","];
[arr addObject:strHow];
[arr addObject:strAre];
[arr addObject:strYou];
arr is the desired array.
I guess this link will help you.
NSString *str = #"Hi,How r u";
NSArray *listItems = [str componentsSeparatedByString:#","];
You have to do,
NSString *str = #"Hi,How r u";
NSArray *arr = [str componentsSeparatedByString:#" "];
And, in order for this to work as you expect, there should be a white-space between "Hi," and "How". Your string should look like #"Hi, How r u".
try this
NSString *str2=#"Hi,How r u";
NSMutableArray *arary = [[NSMutableArray alloc] initWithArray:[str2 componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:#", "]]];
NSLog(#"%#",arary);
if you want , as a object
NSString *str2=#"Hi,How r u";
str2 = [str2 stringByReplacingOccurrencesOfString:#"," withString:#" , "];
NSMutableArray *arary = [[NSMutableArray alloc] initWithArray:[str2 componentsSeparatedByString:#" "]];
NSLog(#"%#",arary);
You can use the NSString method componentsSeparatedByString. Take a look at the reference here.
A quick question about NSArrays and NDictionarys.
I have and NSArray containing NSDictionarys.
The NSDictionary contain a date and a string.
What I would like to do is end up with an NSDictionary with keys dates and values arrays of strings that are on that date.
What would be the best way to do this
NSMutableDictionary *result = [NSMutableDictionary dictionary];
for (NSDictionary *dict in array) {
NSDate *date = [dict objectForKey:#"dateKey"];
NSString *string = [dict objectForKey:#"stringKey"];
NSMutableArray *stringsWithDate = [result objectForKey:date];
if (!stringsWithDate) {
stringsWithDate = [NSMutableArray array];
[result setObject:stringsWithDate forKey:date];
}
[stringsWithDate addObject:string];
}
Note that NSDate is not a "calendar date", so the same day with a different time will be considered as a distinct date in your result dictionary.
As I do not see any reasonable motivation for doing this, let's call it code golf.
NSMutableArray *dates = [NSMutableArray array];
NSMutableArray *strings = [NSMutableArray array];
for (NSDictionary *dict in dictArray) {
[dates addObject:[dict objectForKey:#"date"]];
[strings addObject:[dict objectForKey:#"string"]];
}
NSArray *datesArray = [[NSArray alloc] initWithArray:dates];
NSArray *stringsArray = [[NSArray alloc] initWithArray:strings];
