How to convert int to NSString?

Closed 8 years ago.
Good morning,
First of all excuse me for my english.
A partner has made an app that place an image in the ios display depending the placement id you write on a textfield. He defined the textfield and the variable as a integer, but when he finished he realized that it should be an string. Now its all coded for a int, is there an easy way to parse it to string?

See this other SO question: How can I convert an int to an NSString?
In short, with the code NSString *string = [NSString stringWithFormat:#"%d", theinteger];

int yourIntVar = ??;
NSString *intIntoString = [NSString stringWithFormat:#"%d", yourIntVar];

use this:
myTextfield.text = [NSString stringWithFormat:#"%d",myInt];

int num = 2;
NSString *yourString = [NSString stringWithFormat:#"%d",num];

How can I extract the first 3 characters from a NSString?
For example if I have a string "1234820" How can I extract the numbers 123 from the string and store the result in a new string with the format "1.23 Million" ?
I am counting the the number of characters in the string by using
-(NSString *)returnFormattedString:(NSString *)stringToFormat{
NSString *formatedString;
NSUInteger characterCount = [stringToFormat length];
if (characterCount > 6) {
//???? How do I extract and add a decimal
stringWithThreeCharactersAndDecimal = ????;
NSString *string = [NSString stringWithString:stringWithThreeCharactersAndDecimal];
formatedString = [string stringByAppendingString:#"Million"];
}
return formatedString;
}
do like
assume that is your String
yourString = #"1234820";
// use substringToIndex for fetch First Three Character
yourString=[yourString substringToIndex:3];
// finally convert string to as like 1.23
NSString *finalStr = [NSString stringWithFormat:#"%.2f Million", [yourString floatValue]];
Choice -2
as per Droppys short and good answer is
NSString *finalStr = [NSString stringWithFormat:#"%.2f Million", [yourString floatValue] / 100.0f];

I have a NSString:
NSString *string1 = #"http://example.com/this-is-an-example-post"
By removing a range of characteres I have substringed it to:
NSString *string2 = #"this-is-an-example-post"
But I am struggling to get it into the form of:
NSString *string3 = #"this is an example post"
Any help? Much appreciated.
For example this way
string3 = [string2 stringByReplacingOccurrencesOfString:#"-" withString:#" "];

retrieving integer value from the UITextField into a NSInteger variable
I have users fill in a text box with a number. I want to use this number in a calculation; how can i put it in a variable? So far I only have:
NSInteger *answer = results........
Use intValue or integerValue from the NSString class.
int answer = [myTextField.text intValue];
or
NSInteger answer = [myTextField.text integerValue];
You can also use floatValue and doubleValue for floating-point inputs.
NSInteger answer = [textField.text integerValue];
OR
int answer = [textField.text intValue];

I am trying to convert (or copy?) a NSMutableArray into a NSString. I guess my problem is that I don't really understand the structure of a NSString. In my limited knowledge, a string could look like this: in iphone
Try this code:-
NSString *string = [array componentsJoinedByString:#","];
take the NSMutableString and append every array string into your string
like
string = [string appendString:[NSString stringWithFormat:"%#", [array objectAtIndex:i]]];
