How to convert int to NSString?
Objective CObjective C Problem Overview
I'd like to convert an int to a NSString in Objective C.
How can I do this?
Objective C Solutions
Solution 1 - Objective C
Primitives can be converted to objects with @() expression. So the shortest way is to transform int to NSNumber and pick up string representation with stringValue method:
NSString *strValue = [@(myInt) stringValue];
or
NSString *strValue = @(myInt).stringValue;
Solution 2 - Objective C
NSString *string = [NSString stringWithFormat:@"%d", theinteger];
Solution 3 - Objective C
int i = 25;
NSString *myString = [NSString stringWithFormat:@"%d",i];
This is one of many ways.
Solution 4 - Objective C
If this string is for presentation to the end user, you should use NSNumberFormatter. This will add thousands separators, and will honor the localization settings for the user:
NSInteger n = 10000;
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
formatter.numberStyle = NSNumberFormatterDecimalStyle;
NSString *string = [formatter stringFromNumber:@(n)];
In the US, for example, that would create a string 10,000, but in Germany, that would be 10.000.
