Question

I have an reversed array

 NSArray *reversedArray = [[arr reverseObjectEnumerator] allObjects];

It contains following value

Reversed Array: (
0,
0,
“0.1702998”,
“0.4936719”,
0,
“0.1861508”,
)

So the value which are comming are dynamic, So i want the first non zero value from this array.

How can i do this?

Answer 1

double firstNonZeroValue = 0.0;
for (NSString* stringValue in [array reverseObjectEnumerator]) {
    double value = [stringValue doubleValue];
    if (value != 0.0) {
        firstNonZeroValue = value;
        break;
    }
}

if (firstNonZeroValue != 0.0) {
    ... yay found a non zero value ...
}
