Question

layoutSubviews何时调用的问题

Answer 1

在ContentView中重写layoutSubviews方法，然后根据stausbar的方向判断当前视图的横竖屏。具体代码：
-(void)layoutSubviews{
[super layoutSubviews];
UIDeviceOrientation interfaceOrientation=[[UIApplication sharedApplication] statusBarOrientation];
if (interfaceOrientation == UIDeviceOrientationPortrait || interfaceOrientation == UIDeviceOrientationPortraitUpsideDown) {
//翻转为竖屏时
[self setVerticalFrame];

}else if (interfaceOrientation==UIDeviceOrientationLandscapeLeft ||
interfaceOrientation == UIDeviceOrientationLandscapeRight) {
//翻转为横屏时
[self setHorizontalFrame];
}
}

-(void)setVerticalFrame
{
NSLog(@"竖屏");
[titleLable setFrame:CGRectMake(283, 0, 239, 83)];
[leftView setFrame:CGRectMake(38, 102, 384, 272)];
[rightView setFrame:CGRectMake(450, 102, 282, 198)];
}

-(void)setHorizontalFrame
{
NSLog(@"横屏");
[titleLable setFrame:CGRectMake(183, 0, 239, 83)];
[leftView setFrame:CGRectMake(168, 122, 384, 272)];
[rightView setFrame:CGRectMake(650, 122, 282, 198)];
}

在具体的横竖屏方法中，从新设置各个组件的坐标即可。

接下来在ContentView中添加ArticleView视图。
-(id)initWithCoder:(NSCoder *)aDecoder
{
if ((self = [super initWithCoder:aDecoder])) {

NSArray *arrayContentView =[[NSBundle mainBundle] loadNibNamed:@"ArticleView" owner:self options:nil];
rightView=[arrayContentView objectAtIndex:0];
[self addSubview:rightView];
}
return self;
}
