Convert NSString to few NSIntegers

Question

I have getting data from plist to NSString, in result I see something like this "{{1848,594},{154,176}}". What is the best way to convert every single number to separate NSInteger?

NSString *frame = [myPlistKey objectForKey:@"frame"];

How to convert frame to 4 separate integers?

Answer 1

In this specific case, it looks like you are trying to parse the string representation of an NSRect, in which case you can just use NSRectFromString() from the Foundation framework.

Answer 2

Edit: Since you are not much specific, I will try to cover your situation. If i count with the fact you have NSString *frame filled with {{1848,594},{154,176}}:

    NSString *stringWithoutLeftBracket = [frame
                                     stringByReplacingOccurrencesOfString:@"{" withString:@""];
    NSString *stringWithoutRightBracket = [stringWithoutLeftBracket
                                     stringByReplacingOccurrencesOfString:@"}" withString:@""];
    NSArray *frameArray = [stringWithoutRightBracket componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@","]];

Then you can access objects with indexes like:

NSInteger integer = [[frameArray objectAtIndex:0] integerValue];

But also you could use a for loop like this:

for (NSInteger integer in frameArray) {

    // Do something
}

In my opinion you have a string made from rect, means you could convert it.
