I've been looking for this, but can't find the answer.
I have an NSMutableArray with values who_1, what_2, where_3 etc.
I want to transform this into who, what, where etc.
I already have the value of the integer as a variable, and _ is just a string.
What steps should I take to have all these arrayvalues transformed?

Answer 1

NSArray * arrB = [[NSArray alloc]initWithObjects:#"apple_a",#"ball_b",#"cat_c",#"doll_d",nil];
NSMutableArray * arrA = [[NSMutableArray alloc]init];
for(NSString *strData in arrB)
{
NSArray *arr = [strData componentsSeparatedByString:#"_"];
[arrA addObject:[arr objectAtIndex:0]];
}
and this would be your output
arrA:(
apple,
ball,
cat,
doll
)

Answer 2

You need to apply logic for that, You cant find answers to tricky Questions :)
You need to run a loop.
Separate string with '_'
Loop
for(NSString *s in ary)
{
NSArray *a = [s componentsSeparatedByString:#"_"];
[anotherArray addObject:[a objectAtIndex:0]];
}
and update your array..

Answer 3

Following might help you -
NSRange range = [string rangeOfString:#"_"];
NSString *finalString = [originalString substringToIndex:range.location];
you can have this in loop.
Or you can go for componentSeperatedByStrings.

This might help you
NSMutableArray *tmpAry = [[NSMutableArray alloc] init];
for(NSString *_string in _StringAry)
{
NSCharacterSet *charSet = [NSCharacterSet characterSetWithCharactersInString:#"_0123456789"];
_string = [[_string componentsSeparatedByCharactersInSet:charSet] componentsJoinedByString:#""];
[tmpAry addObject: [[_string copy] autorelease]];
}
NSLog(#"%#", tmpAry); // Gives the modified array
[tmpAry release];
