37 | _nestTableView.headerView = _headerView; 38 | _nestTableView.segmentView = _segmentView; 39 | _nestTableView.contentView = _contentView; 40 | _nestTableView.footerView = _footerView; 41 | _nestTableView.allowGestureEventPassViews = _viewList; 42 | _nestTableView.delegate = self; 43 | _nestTableView.dataSource = self; 44 | ``` 45 | 46 | #### 2. 实现协议 47 | 48 | 在 ViewController 中实现协议 `MFNestTableViewDelegate` & `MFNestTableViewDataSource` 。 49 | 50 | #### 3. 实现 `nestTableViewContentCanScroll:` 方法 51 | 52 | 在这里设置内容可以滚动： 53 | 54 | ```objc 55 | - (void)nestTableViewContentCanScroll:(MFNestTableView *)nestTableView { 56 | 57 | self.canContentScroll = YES; 58 | } 59 | ``` 60 | 61 | #### 4. 监听 `scrollViewDidScroll:` 方法 62 | 63 | 监听 ContentView 中所有 Scrollview 的 `scrollViewDidScroll:` 方法，并在正确的时机设置 Content 不能滚动、设置 Contianer 可以滚动： 64 | 65 | ```objc 66 | - (void)scrollViewDidScroll:(UIScrollView *)scrollView { 67 | 68 | if (!_canContentScroll) { 69 | // 这里通过固定contentOffset，来实现不滚动 70 | scrollView.contentOffset = CGPointZero; 71 | } else if (scrollView.contentOffset.y <= 0) { 72 | _canContentScroll = NO; 73 | // 通知容器可以开始滚动 74 | _nestTableView.canScroll = YES; 75 | } 76 | scrollView.showsVerticalScrollIndicator = _canContentScroll; 77 | } 78 | ``` 79 | 80 | #### 5. 实现 `nestTableViewContainerCanScroll:` 方法 81 | 82 | 在这里把 ContentView 每个 ScrollView 的 contentOffset 设置为 `CGPointZero`： 83 | 84 | ```objc 85 | - (void)nestTableViewContainerCanScroll:(MFNestTableView *)nestTableView { 86 | 87 | // 当容器开始可以滚动时，将所有内容设置回到顶部 88 | for (id view in self.viewList) { 89 | UIScrollView *scrollView; 90 | if ([view isKindOfClass:[UIScrollView class]]) { 91 | scrollView = view; 92 | } else if ([view isKindOfClass:[UIWebView class]]) { 93 | scrollView = ((UIWebView *)view).scrollView; 94 | } 95 | if (scrollView) { 96 | scrollView.contentOffset = CGPointZero; 97 | } 98 | } 99 | } 100 | ``` 101 | 102 | #### 6. （可选）实现 `nestTableViewContentInsetTop:` 方法 103 | 104 | 若当前 `navigationBar.translucent == YES` ，则需要实现 `nestTableViewContentInsetTop:` 方法，并返回下面的值： 105 | 106 | ```objc 107 | - (CGFloat)nestTableViewContentInsetTop:(MFNestTableView *)nestTableView { 108 | 109 | // 因为这里navigationBar.translucent == YES，所以实现这个方法，返回下面的值 110 | if (IS_IPHONE_X) { 111 | return 88; 112 | } else { 113 | return 64; 114 | } 115 | } 116 | ``` 117 | 118 | ### MFSegmentView 119 | 120 | #### 1. 初始化 121 | 122 | ```objc 123 | _segmentView = [[MFSegmentView alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.view.bounds), 40)]; 124 | _segmentView.delegate = self; 125 | _segmentView.itemWidth = 80; 126 | _segmentView.itemFont = [UIFont systemFontOfSize:15]; 127 | _segmentView.itemNormalColor = [UIColor colorWithRed:155.0 / 255 green:155.0 / 255 blue:155.0 / 255 alpha:1]; 128 | _segmentView.itemSelectColor = [UIColor colorWithRed:244.0 / 255 green:67.0 / 255 blue:54.0 / 255 alpha:1]; 129 | _segmentView.bottomLineWidth = 60; 130 | _segmentView.bottomLineHeight = 2; 131 | _segmentView.itemList = @[@"列表1", @"列表2", @"列表3", @"图片", @"网页"]; 132 | ``` 133 | 134 | #### 2. 实现协议 135 | 136 | 在 ViewController 中实现协议 `MFSegmentViewDelegate`。 137 | 138 | #### 3. 实现方法 139 | 140 | 实现 `segmentView: didScrollToIndex:` 方法，可以监听 SegmentView 切换 Index 后的回调。 141 | 142 | ### MFPageView 143 | 144 | #### 1. 初始化 145 | 146 | ```objc 147 | _contentView = [[MFPageView alloc] initWithFrame:self.view.bounds]; 148 | _contentView.delegate = self; 149 | _contentView.dataSource = self; 150 | ``` 151 | 152 | #### 2. 实现协议 153 | 154 | 在 ViewController 中实现协议 `MFPageViewDataSource` & `MFPageViewDelegate` 。 155 | 156 | #### 3. 实现方法 157 | 158 | 1. 实现 `numberOfPagesInPageView:` 方法，返回总 Page 数。 159 | 2. 实现 `pageView: pageAtIndex:` 方法，返回每个 Index 对应的 View。 160 | 3. 实现 `pageView: didScrollToIndex:` 方法，可以监听 PageView 切换 Index 后的回调。 161 | 162 | 163 | ### MFTransparentNavigationBar 164 | 165 | 166 | #### 1. 将 NavigationBar 的类型设置为 `MFTransparentNavigationBar` 167 | 168 | 1. 通过 `initWithNavigationBarClass: toolbarClass:` 来设置。 169 | 2. 在 xib 中设置。 170 | 171 | #### 2. 设置 `MFTransparentBarButtonItem` 172 | 173 | 为 `MFTransparentBarButtonItem` 添加 `viewNormal` 和 `viewSelected` ，并将 `MFTransparentBarButtonItem` 添加到 `MFTransparentNavigationBar` 中。 174 | 175 | #### 3. 设置透明度 176 | 177 | 调用 `setBackgroundAlpha:` 来设置透明度。当 Alpha 小于 `0.95` 时， Title 隐藏 ，显示 `viewNormal` ；当大于等于 `0.95` 时， Title 显示 ，显示 `viewSelected` 。 178 | -------------------------------------------------------------------------------- /image/img1.jpg: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/lmf12/MFNestTableView/fbef62e3ab814a7633332bd8dc99fef35d734d7f/image/img1.jpg -------------------------------------------------------------------------------- /image/img2.jpg: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/lmf12/MFNestTableView/fbef62e3ab814a7633332bd8dc99fef35d734d7f/image/img2.jpg -------------------------------------------------------------------------------- /image1.gif: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/lmf12/MFNestTableView/fbef62e3ab814a7633332bd8dc99fef35d734d7f/image1.gif -------------------------------------------------------------------------------- /image2.jpg: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/lmf12/MFNestTableView/fbef62e3ab814a7633332bd8dc99fef35d734d7f/image2.jpg --------------------------------------------------------------------------------
