10个开发小技巧

1.隐藏多余的tableView的cell分割线

self.tableView.tableFooterView= [[UIView alloc]init];

2.取消系统自带的返回字样

[[UIBarButtonItem appearance]setBackButtonTitlePositionAdjustment:UIOffsetMake(0, -60) forBarMetrics:UIBarMetricsDefault];

3.滑动时隐藏navigation

self.navigationController.hidesBarsOnSwipe=YES;

4.页面跳转是隐藏tabBar

TwoViewController *twoVC = [[TwoViewController alloc] init];

twoVC.hidesBottomBarWhenPushed =YES;

5.ScrollView不能滑到顶

self.automaticallyAdjustsScrollViewInsets=NO;

6.按钮点击发光效果

button.showsTouchWhenHighlighted =YES;

7.长按手势只执行一次

if（sender.state == UIGestureRecognizerState）

8.隐藏状态栏

- (BOOL)prefersStatusBarHidden

{

returnYES;

}

9.在使用view的缩放的时候，layer.border.width随着view的放大，会出现锯齿化的问题。

self.layer.allowsEdgeAntialiasing = YES;

10、在自定义返回按钮的时候，侧滑手势返回往往默认失效了，怎么让侧滑有效呢

    UIButton  *btn =[UIButton buttonWithType:UIButtonTypeCustom];

    [btn setTitle:@"返回" forState:UIControlStateNormal];

    [btn addTarget:self action:@selector(back) forControlEvents:UIControlEventTouchUpInside];

    btn.frame=CGRectMake(0, 0, 60, 40);

    [btn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

    UIBarButtonItem  *item =[[UIBarButtonItem alloc]initWithCustomView:btn];

    self.navigationItem.leftBarButtonItem=item;

添加下面这一句代码即可

 self.navigationController.interactivePopGestureRecognizer.delegate=(id)self;
