I made TUSplitSyncScrollView like below images. <img src="https://i.stack.imgur.com/plBWX.png" alt="enter image description here"> <img src="https://i.stack.imgur.com/2MCfp.png" alt="enter image description here"> <img src="https://i.stack.imgur.com/As7qi.png" alt="enter image description here"> In this code, I used KVO for observing another window's behavior as below: <pre><code>- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context; { if (keyPath == @"observedPresentScale") { // 自身のzoomScaleに監視しているobservedPresentScaleの値を代入する // まず拡大縮小可能にする self.maximumZoomScale = 1000.0; self.minimumZoomScale = 0.001; self.zoomScale = [change[@"new"] floatValue]; // ここで拡大縮小禁止にする self.maximumZoomScale = self.zoomScale; self.minimumZoomScale = self.zoomScale; printf("zoomScale = %f\n", self.zoomScale); } else if (keyPath == @"observedContentOffsetY") { self.contentOffset = CGPointMake(self.contentOffset.x, [change[@"new"] floatValue]); } } </code></pre> And both two views observe each other. <pre><code>int opt = NSKeyValueObservingOptionOld | NSKeyValueObservingOptionNew; // rightSplitedScrollViewをleftSplitedScrollViewのオブザーバにする [leftSplitedScrollView addObserver:rightSplitedScrollView forKeyPath:@"observedPresentScale" options:opt context:NULL]; [leftSplitedScrollView addObserver:rightSplitedScrollView forKeyPath:@"observedContentOffsetY" options:opt context:NULL]; // leftSplitedScrollViewをrightSplitedScrollViewのオブザーバにする [rightSplitedScrollView addObserver:leftSplitedScrollView forKeyPath:@"observedContentOffsetY" options:opt context:NULL]; // [rightSplitedScrollView addObserver:leftSplitedScrollView forKeyPath:@"observedPresentScale" options:opt context:NULL]; </code></pre> You can run the actual project from here:<a href="https://github.com/weed/TUSplitSyncScrollView" rel="nofollow noreferrer">https://github.com/weed/TUSplitSyncScrollView</a>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
