Question

I was trying to use a multiple value in a for loop. if I create two separate for loops, the code is repeated twice, so I tried this:

for ((NSString* Key in [Dictionary allKeys]) && (NSString* Key2 in [Dictionary allValues])){

But no way!! How can I do it??

Answer 1

First of all, variable names should start with a lower case letter.

Do you know the “usual” form of a for loop? The one you’re using is just a short cut for this:

for (int i = 0; i < [myArray count]; i++) {
    id obj = [myArray objectAtIndex:i];
    // do something with the object
}

So in your case, you could write

NSArray *allKeys = [dictionary allKeys];
for (int i = 0; i < [allKeys count]; i++) {
    NSString *key = [allKeys objectAtIndex:i];
    NSObject *obj = [dictionary objectForKey:key];
    // do something 
}
