"Auto Layout still required after executing -layoutSubviews” iOS7上崩溃sdk缺陷

标签：ios7

在iOS7系统上，我项目工程里写了一个CinemaMemberView，添加到一个viewController中，结果崩溃了。iOS8和iOS6上则不会崩溃。

Terminating app due to uncaught exception ‘NSInternalInconsistencyException‘, reason: ‘Auto Layout still required after executing -layoutSubviews. CinemaMemberView‘simplementation of -layoutSubviews needs to call super.‘

CinemaMemberView的layoutSubviews是这样的：

-(void)layoutSubviews{
    [super layoutSubviews];
    if (self.layoutType == ECinemaViewType_Wide_button) {
        [self layoutWideType];
        [self layoutWideTypeOnlyButton];
    }else if (self.layoutType == ECinemaViewType_Wide_logo){
        [self layoutWideType];
        [self layoutWideTypeOnlyLogo];
    }
    else {
        [self layoutNarrowType];
    }
}

解决办法是，将super layoutSubviews放到layoutSubviews的最后，问题是解决了，但真正崩溃的原因还不明确。

-(void)layoutSubviews{
    /*逻辑代码*/
    ...
    /*逻辑代码*/
    [super layoutSubviews];
}
