IOS 杂技

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

自定义了leftBarButtonItem，左滑返回手势失效

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]

initWithImage:img

style:UIBarButtonItemStylePlain

target:self

action:@selector(onBack:)];

self.navigationController.interactivePopGestureRecognizer.delegate = (id<UIGestureRecognizerDelegate>)self;

scrollview不能再viewController滑到订：

self.automaticallyAdjustsScrollViewInsets = NO;

怎么在不新建一个Cell的情况下调整separaLine的位置?

_myTableView.separatorInset = UIEdgeInsetsMake(0, 100, 0, 0);

导航条返回键带的title太讨厌，去掉title
[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(0, -60)

forBarMetrics:UIBarMetricsDefault]
