BLOCK Code BLOCK

OC Syntax:-(NSInteger) subtract :( NSInteger) paramValue from :( NSInteger) paranFrom {return paramFrom-paramValue;} C Syntax: NSInteger subtract (NSInteger paramValue, NSInteger paramFrom) {return paramFrom-paramValue; www.2cto.com}: NSInteger (^ subtract) (NSInteger, NSInteger) = ^ (NSInteger paramValue, NSInteger paramFrom) {return paramFrom-paramValue ;}; this makes it easy to see the difference between block and oc. The simplest form of an independent Block Object: void (^ simpleBlock) (void) = ^ {/* Implement the block object here */}
