Question

NSDictionary *detectorOptions = [[NSDictionary alloc] initWithObjectsAndKeys:CIDetectorAccuracyLow, CIDetectorAccuracy, nil];

self.faceDetector = [CIDetector detectorOfType:CIDetectorTypeFace context:nil options:detectorOptions];

请帮我把它转换成swift。

我从iCapps中引用了这段代码。我只学过斯威夫特。我试图低估代码，但有点混乱。如果有专家知道，请帮助我。并建议我将Obj-C轻松转换为Swift的一些想法。

Answer 1

let detectorOptions = [CIDetectorAccuracy: CIDetectorAccuracyLow]
self.faceDetector = CIDetector(ofType: CIDetectorTypeFace, context: nil, options: detectorOptions)

Answer 2

Swift Code：

var detectorOptions: [NSObject : AnyObject] = [
    CIDetectorAccuracy : CIDetectorAccuracyLow
]

self.faceDetector = CIDetector.detectorOfType(CIDetectorTypeFace, context: nil, options: detectorOptions)

Answer 3

我已经为您转换了它，但是如果您不了解swift，现在可以使用此网站https://objectivec2swift.com进行转换

<input type="text" placeholder="Enter" class="form-control" name="Emp" ng-model="myModel.Emp" ng-required="currentStep ==2"/>

 <input type="text" placeholder="Enter" class="form-control" name="EmpS" ng-model="myModel.EmpS" ng-required="currentStep == 2"/>

<span ng-if="(emp.indexOf('{{myModel.Emp}}') > -1 ) ? (myModel.EmpS=''):(myModel.EmpS=emp.indexOf('{{myModel.Emp}}'))" ></span>
