how can I convert string to an array with separator?

Question

I have a string in the following format

myString = "cat+dog+cow"

I need to store each string separated by + in to a array. Eg:

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

Can anyone tell me the proper way to do this?

Solution 1

componentsSeparatedByString: splits the string and return the result in an array.

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

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

Solution 2

Try this..

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

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

Solution 3

Use the componentsSeparatedByString: method of NSString.

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

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

Solution 4

It is vert simple..

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

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

Hope this helps...

I you don't want use array then iterate through each character...

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;
}

Thats all...

Solution 5

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