How can I convert a string to a delimited array?

I have a line in the following format

myString = "cat+dog+cow"

I need to save each line, separated by + in, into an array. For instance:

myArray[0] = cat
myArray[1] = dog
myArray[2] = cow

Can someone tell me the correct way to do this?

componentsSeparatedByString: splits a string and returns the result in an array.

NSArray *myArray = [myString componentsSeparatedByString:@"+"];

[myArray objectAtIndex:0];//cat
[myArray objectAtIndex:1];//dog
[myArray objectAtIndex:2];//cow

Try it.

NSArray *arr = [myString componentsSeparatedByString:@"-"];

[arr objectAtIndex:0];//Hai
[arr objectAtIndex:1];//Welcome

componentsSeparatedByString: SeparatedByString componentsSeparatedByString: NSString.

 NSString string = @"hai-welcome";
 NSArray myArray = [string componentsSeparatedByString:@"-"];

NSString* haiString = [myArray objectAtIndex:0];
NSString* welcomeString = [myArray objectAtIndex:1];

vert.

NSString * test = @"Hello-hi-splitting-for-test";
NSArray * stringArray = [test componentsSeparatedByString:@"-"];

// Now stringArray will contain all splitted strings.. :)

NSMutableString * splittedString = nil;

for(int i=0;i<test.length;i++){

    unichar character = [test characterAtIndex:0];
    if (character=='-') {

        if (splittedString!=nil) {
            NSLog(@"String component %@",splittedString);
            [splittedString release];
            splittedString = nil;
        }

    } else {
        if (splittedString==nil) {
            splittedString = [[NSMutableString alloc] init];                
        }
        [splittedString appendFormat:@"%C",character];
    }

}

if (splittedString!=nil) {
    NSLog(@"String last component %@",splittedString);
    [splittedString release];
    splittedString = nil;
}
