我用我的UIIimageview
-(IBAction)handlePanFrom:(UIPanGestureRecognizer *)recognizer
在我的代码中,我试图使用两个州:
if([recognizer state] == UIGestureRecognizerStateBegan)
{
NSLog(@"Began");
}
if([recognizer state] == UIGestureRecognizerStateEnded)
{
NSLog(@"End");
}
每次我开始移动 UIIMage View 时, 我都会看到“ Began” 讯息, 但没有任何“ 结束” 讯息...
我做错什么了?
来自苹果文档 :
UIGestureRecognizerStateEnded:
手势识别器已收到被识别为“ / 强” 是连续手势结尾的“ 强” 。 它在运行循环的下一个周期发出动作信息( 或信息), 并将其状态重新发送到 UIGESDERRecognize State Obsable 。
plz 尝试 < 强度 > UIGestureRecognize StateCancelled
