A Boolean value that indicates whether the view controller should automatically adjust its scroll view insets. |
|
|
The default value of this property is YES, which allows the view controller to adjust its scroll view insets in response to the screen areas consumed by the status bar, navigation bar, and toolbar or tab bar. Set to NO if you want to manage scroll view inset adjustments yourself, such as when there is more than one scroll view in the view hierarchy. |
这是指示ViewController是否自动调整subview中的scrollView位置的布尔变量。
此属性的默认值是YES,它使得视图控制器来调节响应的状态栏,导航栏占用的屏幕区域的scrollview,和toolbar或tabBar。,如果你要自己管理插入调整scrollView就设置为NO。
1 [[[UIDevice currentDevice] systemVersion] floatValue]
1 UITableView *tableView; 2 3 float Version=[[[UIDevice currentDevice] systemVersion] floatValue]; 4 5 if(Version>=7.0) 6 7 { 8 9 tableView = (UITableView *)self.superview.superview; 10 11 } 12 13 else 14 15 { 16 17 tableView=(UITableView *)self.superview; 18 19 } 20 21 NSIndexPath *indexPath= [tableView indexPathForCell:self]; 22 23 indexPath = [NSIndexPath indexPathForRow:kImage1IndexinSection:indexPath.row]; 24 25
但是今天所做的项目里用到了tabbarController中一个VC的childVC中使用tableView时候,在切换tabbar的VC时,ChildVC的table会掉64(navigationBar的高度),设置automaticallyAdjustsScrollViewInsets 也无效,
所以只好拿到UITableviewWrapperView强行设置frame:
1 for (UIView *subview in tableView.subviews) 2 { 3 if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewWrapperView"]) 4 { 5 subview.frame = CGRectMake(0, 0, tableView.bounds.size.width, tableView.bounds.size.height); 6 } 7 }
应该是automaticallyAdjustsScrollViewInsets的问题,以后研究
