IOS类似android的view.gone/view.visable

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;
            
        }

    }
}
