IOS 不像android一样,有神view。gone的方法,可以既隐藏当前控件,也可以使底下控件上移。因此,这个自己写个方法:
例如:
//类似于android里的View.Gone - (void)ViewGone:(UIView *)senderView{ if (senderView.hidden == NO) { senderView.hidden = YES; //获取源控件的View NSInteger targetY = senderView.frame.origin.y; NSInteger targetHeightY = senderView.frame.origin.y+senderView.frame.size.height+10; // // NSLog(@"%d",targetY); BOOL isHidden = senderView.hidden; if (isHidden) { for (UIView *view in self.view.subviews) { // NSLog(@"%@",view); NSInteger tempY = view.frame.origin.y; //如果遇到view的Y坐标等于目标的Y坐标,且不为hidden的话,则暂停,恐会覆盖调 if(tempY == targetY && !view.hidden){ break; } if (tempY >= targetHeightY ) { if ([view isMemberOfClass:[UIImageView class]]) { continue; } //上移到目标位置,达到隐藏的效果 CGRect tmpFrame = CGRectMake(view.frame.origin.x, view.frame.origin.y-senderView.frame.size.height-10, view.frame.size.width, view.frame.size.height); view.frame = tmpFrame; } } //senderView = nil; } } }
同理,显示出来的效果是:
//类似于android里的View.Gone - (void)ViewVis:(UIView *)senderView{ if (senderView.hidden == YES) { senderView.hidden = NO; //获取源控件的View NSInteger targetY = senderView.frame.origin.y; NSInteger targetHeightY = senderView.frame.origin.y+senderView.frame.size.height+10; // // NSLog(@"%d",targetY); BOOL isHidden = senderView.hidden; if (!isHidden) { for (UIView *view in self.view.subviews) { // NSLog(@"%@",view); NSInteger tempY = view.frame.origin.y; //如果遇到view的Y坐标等于目标的Y坐标,且不为hidden的话,则暂停,恐会覆盖调 if(tempY == targetY && !view.hidden && view != senderView){ if ([view isMemberOfClass:[UIImageView class]]) { continue; } //上移到目标位置,达到隐藏的效果 CGRect tmpFrame = CGRectMake(view.frame.origin.x, view.frame.origin.y+senderView.frame.size.height+10, view.frame.size.width, view.frame.size.height); view.frame = tmpFrame; } if (tempY >= targetHeightY) { if ([view isMemberOfClass:[UIImageView class]]) { continue; } //上移到目标位置,达到隐藏的效果 CGRect tmpFrame = CGRectMake(view.frame.origin.x, view.frame.origin.y+senderView.frame.size.height+10, view.frame.size.width, view.frame.size.height); view.frame = tmpFrame; } } //senderView = nil; } } }
