objective c - How to parse a string format like [***]***? -

i need parse string [abc]000, , want array containing abc , 000. there easy way it?

i'm using code this:

nsstring *samplestring = @"[abc]000"; nsarray *sampleparts = [samplestring componentsseparatedbystring:@"]"]; nsstring *firstpart = [[[sampleparts objectatindex:0] componentsseparatedbystring:@"["] lastobject]; nsstring *lastpart = [sampleparts lastobject]; 

but it's inefficient , didn't check whether string in format [**]**.

for simple pattern, can parse like:

nsstring *s = @"[abc]000"; nsstring *firstpart = nil; nsstring *lastpart = nil; if ([s characteratindex: 0] == '[') {     nsuinteger = [s rangeofstring:@"]"].location;     if (i != nsnotfound) {         firstpart = [s substringwithrange:nsmakerange(1, - 1)];         lastpart = [s substringfromindex:i + 1];     } } 

or learn use nsscanner class.
