Question

I would like to loop through an array strings and add them to an NSString in the following way:

NSMutableArray *emailsArray = [[NSMutableArray alloc] initWithObjects:@"One", @"Two", @"Three", nil];

for (id email in emailsArray {
    NSString *emails = ??; 
}

So the final NSString should be the following:

NSString *emails = @"One|Two|Three";

Answer 1

Use [emailsArray componentsJoinedByString:@"|"] for this.

Sample:

NSMutableArray *emailsArray = [[NSMutableArray alloc] initWithObjects:@"One", @"Two", @"Three", nil];
NSString *emails = [emailsArray componentsJoinedByString:@"|"];

Here you’ll have emails = @"One|Two|Three".
