Ios UITapgestureRecognitor在第一个选项卡中不工作

这太奇怪了，我创建了一个新项目来测试我是否疯了

2014-02-14 09:04:19.167 TapTest[3395:60b] The frame is {{0, 0}, {320, 568}}
2014-02-14 09:04:19.174 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {320, 519}}
2014-02-14 09:04:27.814 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {568, 271}}

你可以在这里看到这个项目

2014-02-14 09:04:19.167 TapTest[3395:60b] The frame is {{0, 0}, {320, 568}}
2014-02-14 09:04:19.174 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {320, 519}}
2014-02-14 09:04:27.814 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {568, 271}}

我创建了一个项目，初始视图是

UITabBarController

2014-02-14 09:04:19.167 TapTest[3395:60b] The frame is {{0, 0}, {320, 568}}
2014-02-14 09:04:19.174 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {320, 519}}
2014-02-14 09:04:27.814 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {568, 271}}

第一个控制器选项卡有两个UIImageView。每个图像视图上都有一个UITapgestureRecognitor，其操作只记录“点击1”或“点击2”

2014-02-14 09:04:19.167 TapTest[3395:60b] The frame is {{0, 0}, {320, 568}}
2014-02-14 09:04:19.174 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {320, 519}}
2014-02-14 09:04:27.814 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {568, 271}}

如果不使用TabBarController，则一切正常。但是，如果使用TabBarController，则只有第一个tap识别器工作，第二个不工作

2014-02-14 09:04:19.167 TapTest[3395:60b] The frame is {{0, 0}, {320, 568}}
2014-02-14 09:04:19.174 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {320, 519}}
2014-02-14 09:04:27.814 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {568, 271}}

但是，如果您切换到另一个选项卡，然后再切换回来，那么两个识别器都可以工作

2014-02-14 09:04:19.167 TapTest[3395:60b] The frame is {{0, 0}, {320, 568}}
2014-02-14 09:04:19.174 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {320, 519}}
2014-02-14 09:04:27.814 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {568, 271}}

此外，我还尝试在代码中添加Tao手势识别器，同样的情况也发生了

2014-02-14 09:04:19.167 TapTest[3395:60b] The frame is {{0, 0}, {320, 568}}
2014-02-14 09:04:19.174 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {320, 519}}
2014-02-14 09:04:27.814 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {568, 271}}

有人能解释为什么会发生这种情况以及如何解决吗？

我认为这是因为你的应用程序改变了方向。如果启动应用程序并点击第二个UIImageView的左侧（约为图像的前三分之一），它会正确记录“点击2”。我认为你的应用程序会以纵向模式启动，切换到横向模式，并扰乱手势识别器的动作框架。当您离开并返回选项卡时，应用程序已处于横向，因此框架已正确更新

2014-02-14 09:04:19.167 TapTest[3395:60b] The frame is {{0, 0}, {320, 568}}
2014-02-14 09:04:19.174 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {320, 519}}
2014-02-14 09:04:27.814 TapTest[3395:60b] The frame in viewwillappear is {{0, 0}, {568, 271}}

解决方法：一点线索也没有。我只在人像应用上工作，所以我真的不知道这个方向会发生什么。话虽如此，问题的根源可能并不完全是我所说的。但我想说这是需要调查的

识别手势的最大x位置似乎是…320，这是人像应用程序的宽度。这似乎证实了我的观点，即定向对你们的观点有所帮助
