对字典进行排序

字典排序

NSDictionary* dict = @{@"class":@"1",@"group":@"a",@"day":@"day2",@"month":@"12",@"year":@"2016"};

NSArray* keys = [dict allKeys];

NSArray* array = [keys sortedArrayUsingComparator:^NSComparisonResult(id obj1, id obj2) {

return [obj1 compare:obj2 options:NSNumericSearch];

}];

NSLog(@"%@",array);
