最近看到iOS/Mac 开发者钟颖 Cyan 和锤子科技关于是否抄袭的争议，有感而发：这是iOS在分词功能的实现。并没有关于俩这进行谈论。
如何实现拇指大爆炸的功能
1：使用3D Touch来展示内容，这部分简单的说明：
1.1 是否有3D Touch功能
//方法里检测手机是否有3D Touch功能
- (void)viewWillAppear:(BOOL)animated {
if (self.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable) {
//有3D Touch功能
[self registerForPreviewingWithDelegate:(id)self sourceView:self.view];
}else{
//没有3D Touch功能
}
}
1.2 实现3D Touch的代理方法UIViewControllerPreviewingDelegate
pragma mark - 3D Touch Delegate
//点击进入预览模式： 实现该协议方法
- (UIViewController *)previewingContext:(id<UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location {
// check if we're not already displaying a preview controller
if ([self.presentedViewController isKindOfClass:[WJFTextVC class]]) {
return nil;
}
WJFTextVC *previewController = [WJFTextVC new];
previewController.view.backgroundColor = [UIColor blueColor];
previewController.textArray = self.words;
return previewController;
}
//继续按压进入：实现该协议
- (void)previewingContext:(id<UIViewControllerPreviewing>)previewingContext commitViewController:(UIViewController *)viewControllerToCommit {
WJFTextVC *previewController = [WJFTextVC new];
previewController.view.backgroundColor = [UIColor redColor];
previewController.textArray = self.words;
[self showViewController:previewController sender:self];
}
2 重点分词功能的实现（采用系统自带的api）
-(NSArray *)stringTokenizerWithWord:(NSString *)word{
NSMutableArray *keyWords = [NSMutableArray new];
CFStringTokenizerRef ref = CFStringTokenizerCreate(NULL, (__bridge CFStringRef)word, CFRangeMake(0, word.length),kCFStringTokenizerUnitWord,NULL);
CFRange range;
CFStringTokenizerAdvanceToNextToken(ref);
range=CFStringTokenizerGetCurrentTokenRange(ref);
NSString *keyWord;
while (range.length>0)
{
keyWord=[word substringWithRange:NSMakeRange(range.location, range.length)];
[keyWords addObject:keyWord];
CFStringTokenizerAdvanceToNextToken(ref);
range=CFStringTokenizerGetCurrentTokenRange(ref);
}
return keyWords;
}
