[UIView animateWithDuration:0.5 animations:^{ for (i = num; i > _indexOfArray+1; i--) { ((UIDragButton *)[_buttonArray objectAtIndex:i]).frame = ((UIDragButton *)[_buttonArray objectAtIndex:i-1]).frame; } ((UIDragButton *)[_buttonArray objectAtIndex:i]).frame = _frameRect; }];
在block中只需要直接赋值即可实现效果。
若使用CABasicAnimation则较为复杂
定义动画
- (CABasicAnimation *)moveX:(float)time X:(NSNumber *)x // 横向移动 { CABasicAnimation *animation=[CABasicAnimation animationWithKeyPath:@"transform.translation.x"]; animation.toValue=x; animation.duration=time; // 动画持续时间 animation.removedOnCompletion=NO; animation.fillMode=kCAFillModeForwards; animation.delegate = self; return animation; }
使用动画
[self.layer addAnimation:[self moveX:0.1 X:[NSNumber numberWithFloat:x]] forKey:nil];
委托需要协议<NSObject>
