我想利用Swift应用程序在iOS上使用私有框架。我很清楚为什么这不是一个好主意,但是在测试中将很有用,因此App Store的限制不是问题,我已经详尽地研究了替代方案。
我想做的事情与此类似:
dlopen("/Developer/Library/PrivateFrameworks/UIAutomation.framework/UIAutomation".fileSystemRepresentation,RTLD_LOCAL);
let eventsclass = NSClassFromString("UIASyntheticEvents") as? UIASyntheticEvents.Type
eventGenerator = eventsclass!.sharedEventGenerator() as! UIASyntheticEvents
问题是这将导致链接器错误:
Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_UIASyntheticEvents", referenced from:
type metadata accessor for __ObjC.UIASyntheticEvents in Test.o
如果我直接链接框架而不是使用dlopen(),它将在模拟器上正常工作,但无法为实际设备构建,因为SDK中提供的框架仅用于模拟器,并且不会在设备期间链接建立。
我试图在Objective-C中进行这些调用,以防万一只是类型转换.Type
引起问题,但这无济于事。如果我从Swift访问返回的对象,我仍然会遇到相同的错误。
我想我可以在Objective-C中创建一个包装器,将所有的调用直接传递给类,但这似乎是多余的。对于这个问题是否有更优雅的解决方案?
我找到了一个解决方案,它需要一些手动工作,但确实可以在纯Swift中工作。
诀窍是在Swift中创建一个与Objective-C方法匹配的@objc协议,然后对该协议类型进行不安全的转换。就我而言,该协议如下所示:
@objc protocol UIASyntheticEvents {
static func sharedEventGenerator() -> UIASyntheticEvents
//@property(readonly) struct __IOHIDEventSystemClient *ioSystemClient; // @synthesize ioSystemClient=_ioSystemClient;
var voiceOverStyleTouchEventsEnabled: Bool { get set }
var activePointCount: UInt64 { get set }
//@property(nonatomic) CDStruct_3eca2549 *activePoints; // @synthesize activePoints=_activePoints;
var gsScreenScale: Double { get set }
var gsScreenSize: CGSize { get set }
var screenSize: CGSize { get set }
var screen: UIScreen { get set }
var onScreenRect: CGRect { get set }
func sendPinchCloseWithStartPoint(_: CGPoint, endPoint: CGPoint, duration: Double, inRect: CGRect)
func sendPinchOpenWithStartPoint(_: CGPoint, endPoint: CGPoint, duration: Double, inRect: CGRect)
func sendDragWithStartPoint(_: CGPoint, endPoint: CGPoint, duration: Double, withFlick: Bool, inRect: CGRect)
func sendRotate(_: CGPoint, withRadius: Double, rotation: Double, duration: Double, touchCount: UInt64)
func sendMultifingerDragWithPointArray(_: UnsafePointer<CGPoint>, numPoints: Int32, duration: Double, numFingers: Int32)
func sendPinchCloseWithStartPoint(_: CGPoint, endPoint: CGPoint, duration: Double)
func sendPinchOpenWithStartPoint(_: CGPoint, endPoint: CGPoint, duration: Double)
func sendFlickWithStartPoint(_: CGPoint, endPoint: CGPoint, duration: Double)
func sendDragWithStartPoint(_: CGPoint, endPoint: CGPoint, duration: Double)
func sendTaps(_: Int, location: CGPoint, withNumberOfTouches: Int, inRect: CGRect)
func sendDoubleFingerTap(_: CGPoint)
func sendDoubleTap(_: CGPoint)
func _sendTap(_: CGPoint, withPressure: Double)
func sendTap(_: CGPoint)
func _setMajorRadiusForAllPoints(_: Double)
func _setPressureForAllPoints(_: Double)
func moveToPoints(_: UnsafePointer<CGPoint>, touchCount: UInt64, duration: Double)
func _moveLastTouchPoint(_: CGPoint)
func liftUp(_: CGPoint)
func liftUp(_: CGPoint, touchCount: UInt64)
func liftUpAtPoints(_: UnsafePointer<CGPoint>, touchCount: UInt64)
func touchDown(_: CGPoint)
func touchDown(_: CGPoint, touchCount: UInt64)
func touchDownAtPoints(_: UnsafePointer<CGPoint>, touchCount: UInt64)
func shake()
func setRinger(_: Bool)
func holdVolumeDown(_: Double)
func clickVolumeDown()
func holdVolumeUp(_: Double)
func clickVolumeUp()
func holdLock(_: Double)
func clickLock()
func lockDevice()
func holdMenu(_: Double)
func clickMenu()
func _sendSimpleEvent(_: Int)
func setOrientation(_: Int32)
func sendAccelerometerX(_: Double, Y: Double, Z: Double, duration: Double)
func sendAccelerometerX(_: Double, Y: Double, Z: Double)
func _updateTouchPoints(_: UnsafePointer<CGPoint>, count: UInt64)
func _sendHIDVendorDefinedEvent(_: UInt32, usage: UInt32, data: UnsafePointer<UInt8>, dataLength: UInt32) -> Bool
func _sendHIDScrollEventX(_: Double, Y: Double, Z: Double) -> Bool
func _sendHIDKeyboardEventPage(_: UInt32, usage: UInt32, duration: Double) -> Bool
//- (_Bool)_sendHIDEvent:(struct __IOHIDEvent *)arg1;
//- (struct __IOHIDEvent *)_UIACreateIOHIDEventType:(unsigned int)arg1; func _isEdgePoint(_: CGPoint) -> Bool
func _normalizePoint(_: CGPoint) -> CGPoint
//- (void)dealloc;
func _initScreenProperties()
//- (id)init;
}
这是从类转储输出手动转换的。如果有人知道更快的方法,我很想知道。
有了此协议后,您只需执行以下操作:
dlopen("/Developer/Library/PrivateFrameworks/UIAutomation.framework/UIAutomation".fileSystemRepresentation,RTLD_LOCAL)
let eventsclass = unsafeBitCast(NSClassFromString("UIASyntheticEvents"), UIASyntheticEvents.Type.self)
eventGenerator = eventsclass.sharedEventGenerator()
