I created an NSMutableArray and am searching/matching the content of array with NSString's substring but how to do it?
NSMutableArray *tmparray = {#"PPG" , #"AG" , #"HD" };
NSString *tmpstring = #"MAAPPG";
if ([tmparray containsObject:tmpstring] ) {
NSLog(#"String found");
}
But it's not happening because tmparray contain "PPG" not "MAAPPG" how to search for substring matching ?
You can use an NSPredicate to do this, but it may be slow. Here's a simpler approach along the lines of what your trying:
NSMutableArray *tmparray = {#"PPG" , #"AG" , #"HD" };
NSString *tmpstring = #"MAAPPG";
NSRange *tmprange;
for(NSString *string in tmparray) {
tmprange = [tmpstring rangeOfString:string];
if (tmprange.location != NSNotFound) {
NSLog(#"String found");
break;
}
}
how about this
for(NSString *arrString in tmparray){
if([tmpstring rangeOfString:arrString].location != NSNotFound){
NSLog(#"String found");
}
}
NSArray *tmparray = [NSArray arrayWithObjects:#"PPG" , #"AG" , #"HD",nil];
NSString *tmpstring = #"MAAPPG";
NSRange textRange;
for(NSString *string in tmparray)
{
textRange =[tmpstring rangeOfString:string];
if(textRange.location != NSNotFound)
{
NSLog(#"String found ");
}
}
check this by using other substrings also...

Code Snippet:
NSString *tempStr = self.consumerNumber.text;
if ([tempStr hasPrefix:#"0"] && [tempStr length] > 1) {
tempStr = [tempStr substringFromIndex:1];
[self.consumerNumbers addObject:tempStr];>
}
I tried those things and removing only one zero. how to remove more then one zero
Output :001600240321
Expected result :1600240321
Any help really appreciated
Thanks in advance !!!!!
Try to use this one
NSString *stringWithZeroes = #"001600240321";
NSString *cleanedString = [stringWithZeroes stringByReplacingOccurrencesOfString:#"^0+" withString:#"" options:NSRegularExpressionSearch range:NSMakeRange(0, stringWithZeroes.length)];
NSLog(#"Clean String %#",cleanedString);
Clean String 1600240321
convert string to int value and re-assign that value to string,
NSString *cleanString = [NSString stringWithFormat:#"%d", [string intValue]];
o/p:-1600240321
You can add a recursive function that is called until the string begin by something else than a 0 :
-(NSString*)removeZerosFromString:(NSString *)anyString
{
if ([anyString hasPrefix:#"0"] && [anyString length] > 1)
{
return [self removeZerosFromString:[anyString substringFromIndex:1]];
}
else
return anyString;
}
so you just call in your case :
NSString *tempStr = [self removeZerosFromString:#"000903123981000"];
NSString *str = #"001600240321";
NSString *newStr = [#([str integerValue]) stringValue];
If the NSString contains numbers only.
Other wise use this:
-(NSString *)stringByRemovingStartingZeros:(NSString *)string
{
NSString *newString = string;
NSInteger count = 0;
for(int i=0; i<[string length]; i++)
{
if([[NSString stringWithFormat:#"%c",[string characterAtIndex:i]] isEqualToString:#"0"])
{
newString = [newString stringByReplacingCharactersInRange:NSMakeRange(i-count, 1) withString:#""];
count++;
}
else
{
break;
}
}
return newString;
}
Simply call this method:-
NSString *stringWithZeroes = #"0000000016909tthghfghf";
NSLog(#"%#", [self stringByRemovingStartingZeros:stringWithZeroes]);
OutPut: 16909tthghfghf
Try the `stringByReplacingOccurrencesOfString´ methode like this:
NSString *new = [old stringByReplacingOccurrencesOfString: #"0" withString:#""];
SORRY: This doesn't help you due to more "0" in the middle part of your string!
How do I parse HTML file?
I'm getting an HTML file in the below code,I just want to get data in between BinarySecurityToken XML node.
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
if(_data)
{
//Here am getting the below HTML content
NSString* content = [[NSString alloc] initWithData:_data
encoding:NSUTF8StringEncoding];
}
}
<input type="hidden" name="wa" value="wsignin1.0" />
<input type="hidden" name="wresult"
value="<t:RequestSecurityTokenResponse xmlns:t="http://schemas.xmlsoap.org/ws/2005/02/trust">
<t:Lifetime>
<wsu:Created >2013-04-29T11:50:29.895Z</wsu:Created>

aHR0cCUzYSUyZiUyZnNjaGVtYWd0Sjk0JTNk
</wsse:BinarySecurityToken>
Any ideas? Thanks in advance.
You can get using this code
NSRange divRange = [content rangeOfString:#"<wsse:BinarySecurityToken>" options:NSCaseInsensitiveSearch];
if (divRange.location != NSNotFound)
{
NSRange endDivRange;
endDivRange.location = divRange.length + divRange.location;
endDivRange.length = [content length] - endDivRange.location;
endDivRange = [content rangeOfString:#"</wsse:BinarySecurityToken>" options:NSCaseInsensitiveSearch range:endDivRange];
if (endDivRange.location != NSNotFound)
{
divRange.location += divRange.length;
divRange.length = endDivRange.location - divRange.location;
NSLog(#"BinarySecurityToken : %#",[content substringWithRange:divRange]);
}
}
Output :
aHR0cCUzYSUyZiUyZnNjaGVtYWd0Sjk0JTNk
You need and XML parser for that.
There's a tutorial here
For this particular case you can get the ranges of <wsse:BinarySecurityToken> and </wsse:BinarySecurityToken>, construct new range that will provide you location of the token, and get substring in that range.
Sample code:
NSRange openingTagRange = [htmlString rangeOfString:#"<wsse:BinarySecurityToken>"];
NSRange closingTagRange = [htmlString rangeOfString:#"</wsse:BinarySecurityToken>"];
NSRange tokenRange = NSMakeRange(openingTagRange.location + openingTagRange.length, closingTagRange.location - (openingTagRange.location + openingTagRange.length));
NSString *token = [htmlString substringWithRange:tokenRange];
Since your input comes from outside, you should probably check if the ranges' locations are not equal to NSNotFound.
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"index" ofType:#"html"];
NSData * data = [NSData dataWithContentsOfFile:filePath];
TFHpple * tutorialsParser = [[TFHpple alloc] initWithHTMLData:data];
NSString *query = #"//div[#id='BinarySecurityToken']";
NSArray *nodes = [tutorialsParser searchWithXPathQuery:query];
for (TFHppleElement * element in nodes) {
NSLog(#"%#", element);
NSLog(#"%#", [element tagName]);
NSLog(#"%#", [element attributes]);
NSLog(#"%#", [element children]);
for (TFHppleElement *childElement in [element children]) {
NSLog(#"%#", childElement);
}
}
hope this will help you For more try this blog and Git Project Resource may help you and

or another option if you have all the HTML data in NSString you can get data between specific NSString with this function.
-(NSString*)stringBetweenString:(NSString*)start andString:(NSString)end {
NSRange startRange = [self rangeOfString:start];
if (startRange.location != NSNotFound) {
NSRange targetRange;
targetRange.location = startRange.location + startRange.length;
targetRange.length = [self length] - targetRange.location;
NSRange endRange = [self rangeOfString:end options:0 range:targetRange];
if (endRange.location != NSNotFound) {
targetRange.length = endRange.location - targetRange.location;
return [self substringWithRange:targetRange];
}
}
return nil;
}
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 have a string like: "mocktail, wine, beer"
How can I convert this into: "mocktail", "wine", "beer"?
the following gives you the desired result:
NSString *_inputString = #"\"mocktail, wine, beer\"";
NSLog(#"input string : %#", _inputString);
NSLog(#"output string : %#", [_inputString stringByReplacingOccurrencesOfString:#", " withString:#"\", \""]);
the result is:
input string : "mocktail, wine, beer"
output string : "mocktail", "wine", "beer"
You need to use:
NSArray * components = [myString componentsSeparatedByString: #", "];
NSString *string = #"mocktail, wine, beer";
//remove whitespaces
NSString *trimmedString = [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
//get array of string
NSArray *array = [trimmedString componentsSeparatedByString:#","];
NSMutableArray *newArray = [[NSMutableArray alloc] init];
for (NSString *trimmedString in array) {
NSString *newString = [NSMutableString stringWithFormat:#"'%#'", trimmedString];
[newArray addObject:newString];
}
//merge new strings
NSString *finalString = [NSString stringWithFormat:#"%#", [newArray objectAtIndex:0]];
for (NSInteger i = 1; i < [newArray count]; i++) {
finalString = [NSString stringWithFormat:#"%#, %#", finalString, [newArray objectAtIndex:i]];
}
Without knowing spesifically about iOS or objective-c, I assume you could use a split function.
In almost any higher level programming language there is such a function.
Try:
Objective-C split
This gets you an array of Strings. You can then practically do with those what you want to do, e.g. surrounding them with single quotes and appending them back together. :D
I'm developing a custom UIViewController for iPhone that emulates a subset of the MPMediaPickerController for files in my application's local documents directory. In particular, I'm attempting to re-create the Songs tab. I've been successful in creating my new controller, except I can't get the song titles to sort like they do in the iPod Library or the MPMediaPickerController. Here's an example of how the song names need to be sorted:
Awesome Song Title
Cool Song
The Darkest Song Ever
My Song Title
A Really Cool Song
Why Me?
4 Hours Wasted
As you can see, the sorting excludes the leading articles in the song titles and also places songs that begin with a numeric value at the end of the list. Can anyone suggest an efficient sorting function that takes these tules into account?
Since it looks like no one could offer up a solution, I thought I would post the solution I came up with. First, I created a model for my data:
#interface MyModel : NSObject
{
NSString* _value;
NSString* _sortableValue;
}
#property (nonatomic,copy) NSString* value;
- (NSString*)sortableValue;
- (NSString*)comparableString:(NSString*)str;
#end
They key to the model is the comparableString method, which gets used to create the sortableValue. Here's the implementation of the model:
#implementation MyModel
#synthesize value=_value;
-(void)dealloc
{
[_value release];
[_sortableValue release];
[super dealloc];
}
- (void)setValue:(NSString*)value
{
[_value release];
_value = [value copy];
[_sortableValue release];
_sortableTValue = nil;
}
- (NSString*)sortableValue
{
if (_sortableValue == nil)
_sortableValue = [[self comparableString:_value] retain];
return _sortableValue;
}
- (NSString*)comparableString:(NSString*)str
{
if (str == nil)
return nil;
else if ([str length] == 0)
return [NSString stringWithString:str];
NSCharacterSet* numbersSet = [NSCharacterSet decimalDigitCharacterSet];
if ([str rangeOfCharacterFromSet:numbersSet options:0 range:NSMakeRange(0, 1)].location != NSNotFound)
return [NSString stringWithString:str];
NSRange range = NSMakeRange(0, [str length]);
if ([str compare:#"a " options:(NSAnchoredSearch|NSCaseInsensitiveSearch) range:NSMakeRange(0, 2)] == NSOrderedSame)
range.location = 2;
else if ([str compare:#"an " options:(NSAnchoredSearch|NSCaseInsensitiveSearch) range:NSMakeRange(0, 3)] == NSOrderedSame)
range.location = 3;
else if ([str compare:#"the " options:(NSAnchoredSearch|NSCaseInsensitiveSearch) range:NSMakeRange(0, 4)] == NSOrderedSame)
range.location = 4;
range.length -= range.location;
NSCharacterSet* lettersSet = [NSCharacterSet letterCharacterSet];
NSUInteger letterOffset = [str rangeOfCharacterFromSet:lettersSet options:0 range:range].location;
if (letterOffset == NSNotFound)
return [NSString stringWithString:str];
letterOffset -= range.location;
range.location += letterOffset;
range.length -= letterOffset;
return [str substringWithRange:range];
}
#end
In addition to the removing the leading articles from the string, it also removes any leading non-letter characters. I have a song in my iPod library entitled "$ell Your $oul", which ends up in the E section in the MPMediaPickerController. I'm not sure that's what I would have done had I crated the initial sorting algorithm, but I was going to consistency with the MPMediaPickerController, so there you go.
The final piece of the puzzle is the UILocalizedIndexedCollation class. This handy little helper class will help you sort your data to make supplying it to a UITableView via a UITableViewDataSource a piece of cake. Here's a snippet on how to use the UILocalizedIndexedCollation class in conjunction with the model:
// tableData will contain an NSArray for each populated section in the table view
NSMutableDictionary* tableData = [NSMutableDictionary dictionary];
NSMutableArray* myArray = [NSMutableArray array];
// Populate myArray with instances of MyModel
UILocalizedIndexedCollation* indexer = [UILocalizedIndexedCollation currentCollation];
for (MyModel* data in myArray)
{
NSInteger index = [indexer sectionForObject:data collationStringSelector:#selector(sortableValue)];
NSNumber* key = [[NSNumber alloc] initWithInteger:index];
NSMutableArray* array = [tableData objectForKey:key];
if (array == nil)
{
array = [NSMutableArray new]; // Will be released after creating a sorted array in the following section
[tableData setObject:array forKey:key];
}
[array addObject:data];
[key release];
}
[tableData enumerateKeysAndObjectsUsingBlock:^(id key, id array, BOOL* stop)
{
NSMutableArray* sortedArray = [[indexer sortedArrayFromArray:array collationStringSelector:#selector(sortableValue)] mutableCopy];
[tableData setObject:sortedArray forKey:key];
[array release];
}];
One quick note about UILocalizedIndexedCollation (from Apple's documentation):
If the application provides a
Localizable.strings file for the
current language preference, the
indexed-collation object localizes
each string returned by the method
identified by selector.
So make sure you provide a Localizable.strings for each language you want to support, or your table view will only have sections A-Z and #.
It took me a while to work out all of the details on this, so I hope it becomes useful for other people. If you see any ways I can improve this, please let me know!
You may need to consider certain characters with accents as well such as è, é, ò, à, ù, ì.
So I slightly modified your code to incorporate this. Your code is a great contribution to all of us iphone developers
