如何在 Map 视图中检测到夹点和点击？-Java 学习之路

你们所有人我一直在研究 Map 视图，但我无法解决捏和点击检测问题 . 我想检测捏并点击 Map 视图 .

我试过在iPhone MapView中使用以下代码

UITapGestureRecognizer * Tap = [[UITapGestureRecognizer alloc] initWithTarget：self action：@selector（checktap）]; [self.mapView addGestureRecognizer：Tap]; [点击发布];

UIPinchGestureRecognizer * pinch = [[UIPinchGestureRecognizer alloc] initWithTarget：self action：@selector（checkpinch）]; [self.mapView addGestureRecognizer：pinch]; [捏释];

水龙头工作但夹点检测不起作用 .

请帮我 .

提前致谢 .

在您的视图中添加以下代码确实加载并在您的.h文件中添加Gesture识别器委托 .

[self.view insertSubview:mapView atIndex:0];

//Gesture reconizer
UIPinchGestureRecognizer *pinch = [[UIPinchGestureRecognizer alloc]initWithTarget:self action:@selector(checkpinch)];
[pinch setDelegate:self];
[pinch setDelaysTouchesBegan:YES];
[self.mapView addGestureRecognizer:pinch];
[pinch release];

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(checktap)];
[singleTap setDelegate:self];
singleTap.numberOfTapsRequired = 1;
singleTap.numberOfTouchesRequired =2;
[self.mapView addGestureRecognizer:singleTap];
[singleTap release];


UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(checktap)];
[doubleTap setDelegate:self];
doubleTap.numberOfTapsRequired = 2;
doubleTap.numberOfTouchesRequired =1;
[self.mapView addGestureRecognizer:doubleTap];
[doubleTap release];
