LTMorphingLabel Swift4误差

Question

我不犯错误。

无法将类型'(_) -> ()‘的值转换为预期的参数类型'LTEmitterConfigureClosure?’(又名'Optional<(CAEmitterLayer，CAEmitterCell) -> ()>')

我怎么才能修好它？

self.emitterView.createEmitter(
                "fragments",
                particleName: "Fragment",
                duration: 0.6
                ) {_ in}.update { (layer, _) in
                    if progress > end {
                        layer.birthRate = 0
                    }
                }.play()

只需将尾随闭包{_ in}替换为configureClosure: nil，即。

self.emitterView.createEmitter(
                "fragments",
                particleName: "Fragment",
                duration: 0.6,
                configureClosure: nil).update { (layer, _) in
                    if progress > end {
                        layer.birthRate = 0
                    }
                }.play()
