例如接收者類型'UIView'消息沒有聲明帶有選擇器'addAnimation：forKey：'的方法

Question

CABasicAnimation *theAnimation; 
theAnimation=[CABasicAnimation animationWithKeyPath:@"transform.translation.y"]; 
theAnimation.duration=0.5; 
theAnimation.repeatCount=0; 
theAnimation.autoreverses=NO; 
theAnimation.fromValue=[NSNumber numberWithFloat:100]; 
theAnimation.toValue=[NSNumber numberWithFloat:0]; 
//[self.quntityView animationDidStart:theAnimation]; 
[self.quntityView addAnimation:theAnimation forKey:@"animateLayer"]; 

Answer 1

addAnimation:forKey:是CALayer上的方法。你不能只在UIView上調用它。

嘗試：

[self.quntityView.layer addAnimation:theAnimation forKey:@"animateLayer"];
