正确的家伙，我刚开始进入Xcode 4，打算开始制作iPhone应用程序。没有太大的主题，不是游戏等......但我正在努力与这种捏手势....捏捏手势识别器
由于某种原因，当我使用iphone 5.0模拟器时，一切正常......但是，当涉及到出口和尝试它在我的iPhone 3G上，当我用捏设施加载屏幕时出现错误。
我使用此代码为捏合手势：
在.h文件：
-(IBAction)Zoom:(UIPinchGestureRecognizer *)recognizer;
在.m文件：
-(IBAction)Zoom:(UIPinchGestureRecognizer *)recognizer{
recognizer.view.transform = CGAffineTransformScale(recognizer.view.transform, recognizer.scale,recognizer.scale); recognizer.scale = 1;
}
但是当我点击我的按钮使用此代码加载具有手势功能（OurWorkSubOne）的屏幕：
-(IBAction)switchViewSeven:(id)sender {
OurWorkSubOne *second = [[OurWorkSubOne alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:second animated:YES];
}
我得到这样的输出：

你在哪里添加你的手势识别？你是通过Interface Builder来做的吗？ – 2012-01-27 14:29:10
您的iPhone 3G运行iOS版本是什么？ – amattn 2012-01-27 14:30:52
是的，我通过界面生成器添加它，刚删除它，并重新加载到我的iPhone上的应用程序，我没有得到任何错误和页面正在显示？ – WLyne86 2012-01-27 14:32:03
