Ios 在TableViewController中将TapGestureRecognitor与profileimage一起使用
下午好 我正在尝试实现一个“查看用户配置文件”按钮,它将显示一个包含用户信息的新ViewController。我在按下图像时在图像配置文件上实现了TapGestureRecognitor(它是TableViewController) 主要问题是,当我按下用户图像时,它显示了错误的ProfileViewController,因为当我按下另一行时,我的TableViewController似乎没有更新@username(它显示了我看到的最新配置文件) 我已经尝试了很多教程,但在任何情况下都不起作用,因为每当我按下配置文件图像时,它都会显示(我已经测试过)错误的用户名 如何将用户名更新为我按下的用户名? 查找我的XCode的图像: 这是我的TableViewController.m(它在@“segueprofile”中)Ios 在TableViewController中将TapGestureRecognitor与profileimage一起使用,ios,objective-c,uitableview,tableview,uitapgesturerecognizer,Ios,Objective C,Uitableview,Tableview,Uitapgesturerecognizer,下午好 我正在尝试实现一个“查看用户配置文件”按钮,它将显示一个包含用户信息的新ViewController。我在按下图像时在图像配置文件上实现了TapGestureRecognitor(它是TableViewController) 主要问题是,当我按下用户图像时,它显示了错误的ProfileViewController,因为当我按下另一行时,我的TableViewController似乎没有更新@username(它显示了我看到的最新配置文件) 我已经尝试了很多教程,但在任何情况下都不起作用,

对于(int i=0;i)您的代码不显示您添加了点击手势的位置。还显示了点击手势的选择器。i@FawadMasud,我已将点击手势识别器连接到故事板中的图像配置文件。您需要故事板的更多信息或屏幕截图吗?谢谢。您能给我performsguewithidentifier
方法的内容吗?
