仿今日头条SegmentedControl
几行代码搞定
```
MLViewController *vv = [[MLViewController alloc] init]; OneViewController * alloc] init];
TwoViewController *two = [[TwoViewController alloc] init];
ThrViewController *thr = [[ThrViewController alloc] init];
FouViewController *fou = [[FouViewController alloc] init];

MLBasePageViewController *vc = [[MLBasePageViewController alloc] init];
vc.VCArray = @[vv, one, two, thr, fou]; vc.secti @"玛丽玛丽", @"玛丽玛", @"玛丽", @"玛丽玛"];
[self.navigationController pushViewController:vc animated:YES];
```
