64 | ``` 65 | 所以，看一下contentInsetAdjustmentBehavior是何方神圣： 66 | ``` 67 | typedef NS_ENUM(NSInteger, UIScrollViewContentInsetAdjustmentBehavior) { 68 | UIScrollViewContentInsetAdjustmentAutomatic, // Similar to .scrollableAxes, but will also adjust the top & bottom contentInset when the scroll view is owned by a view controller with automaticallyAdjustsScrollViewContentInset = YES inside a navigation controller, regardless of whether the scroll view is scrollable 69 | UIScrollViewContentInsetAdjustmentScrollableAxes, // Edges for scrollable axes are adjusted (i.e., contentSize.width/height > frame.size.width/height or alwaysBounceHorizontal/Vertical = YES) 70 | UIScrollViewContentInsetAdjustmentNever, // contentInset is not adjusted 71 | UIScrollViewContentInsetAdjustmentAlways, // contentInset is always adjusted by the scroll view's safeAreaInsets 72 | } API_AVAILABLE(ios(11.0),tvos(11.0)); 73 | 74 | /* Configure the behavior of adjustedContentInset. 75 | Default is UIScrollViewContentInsetAdjustmentAutomatic. 76 | */ 77 | @property(nonatomic) UIScrollViewContentInsetAdjustmentBehavior contentInsetAdjustmentBehavior API_AVAILABLE(ios(11.0),tvos(11.0)); 78 | ``` 79 | 看起来这和iOS11搞的safeArea有关，这个先放一遍，看看怎么适配： 80 | ``` 81 | #define adjustsScrollViewInsets_NO(scrollView,vc)\ 82 | do { \ 83 | _Pragma("clang diagnostic push") \ 84 | _Pragma("clang diagnostic ignored \"-Warc-performSelector-leaks\"") \ 85 | if ([UIScrollView instancesRespondToSelector:NSSelectorFromString(@"setContentInsetAdjustmentBehavior:")]) {\ 86 | [scrollView performSelector:NSSelectorFromString(@"setContentInsetAdjustmentBehavior:") withObject:@(2)];\ 87 | } else {\ 88 | vc.automaticallyAdjustsScrollViewInsets = NO;\ 89 | }\ 90 | _Pragma("clang diagnostic pop") \ 91 | } while (0) 92 | ``` 93 | 上面是公司里面一个大神写的，这样就可以在Xcode8上面跑了。 94 | #### 2.tableView默认使用Self-Sizing 95 | 这个配合estimatedRowHeight、estimatedSectionFooterHeight、estimatedSectionHeaderHeight使用，可以预估高度。之前，设置header或者footer高度为0时，需要设置height=0.1，才会起作用，如果直接设置为0，则会使用默认高度。iOS11由于自动使用预估高度，所以，忽略了设置的高度，使原来的高度增大了。只要把这几个属性设置为0就可以解决。 96 | 97 | ### 搞事三：iPhoneX底部tabbar的高度改变 98 | iPhoneX不止多了刘海，底部还有一个半角的矩形，使得tabbar多出来了34p的高度，不过不管导航栏和tabbar一般系统都会自动适配safeArea。 99 | 100 | ![iPhoneX tabbar.png](http://upload-images.jianshu.io/upload_images/968977-be7d00e5fded4863.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 101 | 102 | ### 搞事四：iOS11 iPhoneX页面push时tabbar位置变化 103 | 直接上图： 104 | ![iOS11 iPhoneX Tabbar.gif](http://upload-images.jianshu.io/upload_images/968977-1f1703830fef106d.gif?imageMogr2/auto-orient/strip) 105 | 106 | 可以看到在页面push的时候，tabbar的frame上移了，这个只有在iPhoneX上面才能看到(因为iPhoneX的TabBar的高度不一样)，有可能是模拟器的bug，但是，具体要到真机出来才知道。下面说说修复的几种办法： 107 | ###### （1）将导航栏的代理设置为当前的controller，然后在将要展示下个页面的方法里修正TabBar的frame。 108 | ``` 109 | - (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated { 110 | if (![[[UIDevice currentDevice] modelName] isEqualToString: @"iPhone X"]) { 111 | return; 112 | } 113 | CGRect frame = self.tabBarController.tabBar.frame; 114 | if (frame.origin.y < ([UIScreen mainScreen].bounds.size.height - 83)) { 115 | frame.origin.y = [UIScreen mainScreen].bounds.size.height - 83; 116 | self.tabBarController.tabBar.frame = frame; 117 | } 118 | } 119 | ``` 120 | ###### （2）新建一个类，继承UITabBar，然后在setFrame:里面做判断修正，将改类替换系统默认的TabBar。 121 | ``` 122 | - (void)setFrame:(CGRect)frame { 123 | if ([[[UIDevice currentDevice] modelName] isEqualToString: @"iPhone X"]) { 124 | if (frame.origin.y < ([UIScreen mainScreen].bounds.size.height - 83)) { 125 | frame.origin.y = [UIScreen mainScreen].bounds.size.height - 83; 126 | } 127 | } 128 | [super setFrame: frame]; 129 | } 130 | ``` 131 | ###### （3）其他方法。 132 | 133 | ### 总结： 134 | iOS11系统改变还是比较大的，某些地方需要注意适配，不然会出现很奇怪的现象。暂时，在iOS11遇到这么多坑，以后遇到会继续分享的。 135 | 136 | 137 | ### 参考： 138 | [你可能需要为你的 APP 适配 iOS 11](http://www.10tiao.com/html/330/201707/2653579210/1.html) 139 | --------------------------------------------------------------------------------
