presentModalViewController可以用来弹出一个模态对话框
[[self parentViewController]
dismissModalViewControllerAnimated:YES];用这个来取消对话框
获取资源文件路径
[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:(fileName)]
这样就可以识别.摇动了,真诡异:
- (BOOL)canBecomeFirstResponder {
return
YES;
}
- (void)viewDidAppear:(BOOL)animated
{
[self
becomeFirstResponder];
}
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {
if ( event.subtype ==
UIEventSubtypeMotionShake ) {
// Do something
NSLog(@"Don't shake me!!");
}
}
