NSArray排序

排序

• 数值排序
  NSArray *tempArr=[NSArray arrayWithObjects:@"1",@"12",@"4",@"05",nil];
  NSArray *sortArr_=[tempArr sortedArrayWithOptions:NSSortConcurrent usingComparator:^NSComparisonResult(id _Nonnull obj1, id Nonnull obj2) {
  if ([obj1 floatValue]>[obj2 floatValue]) {
  return NSOrderedDescending;
  }else if ([obj1 floatValue]<[obj2 floatValue]){
  return NSOrderedAscending;
  }else{
  return NSOrderedSame;
  }
  }];
  NSLog(@"数值排序=%@",sortArr);
