Question

I am just starting on Objective-C and XCode today.

I’ve made a

NSMutableArray

containing a bunch of strings.

I am looping through my array like this:

for (NSString *test in array) {
}

Now, how do I manage to show each of these values on the screen, standing underneath each other? I am not sure which UI element would be proper, and how to actually use that element (I don’t know what element it is yet, but I only have knowledge on TextField, Button and Label so far).

Answer 1

Use a UILabel and set numberOfLines to 0 to have infinite lines.

UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 300, 200)];
myLabel.numberOflines = 0;
[self.view addSubview:myLabel];

NSString *testText = @"";
for (NSString *test in array) {
    testText = [testText stringByAppendingFormat:@"%@\n", text];
}
myLabel.text = testText;
