Question

NSMutableArray *nameArray = [[NSMutableArray alloc] init];
[nameArray addObject:@"abc"];
[nameArray addObject:@"cdf"];
[nameArray addObject:@"jkl"];

//Use a for each loop to iterate through the array
for (NSString *s in nameArray) {
    NSLog(@"value is %@", s);
}

The above code shows all the values of nameArray. But I want to assign all those values to these NSString:

NSString *a;
NSString *b;
NSString *cd;

An aray can have 1 or more elements but not more than 5.

Actually,I have 5 buttons, each button on click will add a NSString value(values are: f1,f2,f3,f4 and f5) to NSMutableArray. Now its upto the user if he clicks 2 buttons or 3 or 5 in a day. Now all these values will be saved in NSMutableArray (which can be 1 or 2 but not more than 5). That NSMutableArray will be saved in NSUserDefaults. This NSMutableArray than will be used in another view where I have some UIImageView (1,2,3,4 and 5). Now when I will get the string values from that Array(f1,f2,f3). If it is f1 then an image will be assigned to UIImage 1 if it is f3 then to image 3 and so on.

How to achieve this?

Answer 1

I would do something like that:

NSArray *array = [NSArray arrayWithObjects:@"A", @"B", @"C", @"D", @"E", nil];
NSString *a = nil, *b = nil, *c = nil, *d = nil, *e = nil;
NSUInteger idx = 0;

for ( NSString *string in array )
{
    switch ( idx++ ) {
        case 0: a = string; break;
        case 1: b = string; break;
        case 2: c = string; break;
        case 3: d = string; break;
        case 4: e = string; break;
    }
}
