普遍认为效率不错的JSONKit,与苹果官方的JSONSerialization究竟差距有多大???? ##JSONKit enter image description here

##NSSerialization enter image description here

##效率比较代码(执行100*1000次查看内存消耗)

• (void)loadJSONKit {

  NSString *path = [[NSBundle mainBundle] pathForResource:@"videos.json" ofType:nil];

  NSURL *url = [NSURL fileURLWithPath:path];

  NSURLRequest *request = [NSURLRequest requestWithURL:url];

  [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue]completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {

   CFAbsoluteTime start = CFAbsoluteTimeGetCurrent();
   for (int i=0; i<100*1000; i++) {
   [[JSONDecoder decoder] objectWithData:data];
   }
   NSLog(@"JSONKit耗时=====>%f", CFAbsoluteTimeGetCurrent() - start);
  

  }]; }

• (void)loadJSONSerialization {

  NSString *path = [[NSBundle mainBundle] pathForResource:@"videos.json" ofType:nil];

   }
   NSLog(@"NSJSONSerialization耗时=====>%f", CFAbsoluteTimeGetCurrent() - start);
  

  }]; }
