[英]UITouches not detecting
My UItouches is not detecting in my Slideshow nib file. 我的UItouches没有在我的Slidenib文件中检测到。 What is the problem? 问题是什么? Can anyone help? 有人可以帮忙吗?
@class Slideshow;
@interface RootViewController : UIViewController{
PreferencesController *preferencesController;
Slideshow *slideshow;}
Slideshow Implementation 幻灯片实施
@implementation Slideshow
- (void) touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event
{
NSLog(@"touches begin");
}
- (void)viewDidLoad
{
UIImageView *frontView = [[UIImageView alloc] initWithFrame:self.view.bounds];
frontView.backgroundColor = [UIColor blackColor];
frontView.image = [UIImage imageNamed:@"apple.png"];
frontView.userInteractionEnabled = YES;
[self.view addSubview:frontView];
[frontView release];
}@end
Slideshow is a UIViewController
and touchesBegan
is only called on a UIView
. 幻灯片是UIViewController
, touchesBegan
仅在UIView
上调用。 You need to subclass UIView
to capture touches. 您需要将UIView
子类化以捕获触摸。
