ios7 swipe back bug

[code1303009]

when push a new viewcontroller,set the tabbar hide, then in the new viewcontroller, swipe to go back to first viewcontroller,offset of the contentview will be abnormal. It shows only in ios7.0+.

I had fix it by writing follow in your method - (void)setTabBarHidden:(BOOL)hidden animated:(BOOL)animated {
_tabBarHidden = hidden;
__weak DMTabBarController *weakSelf = self;

void (^block)() = ^{
    CGSize viewSize = weakSelf.view.bounds.size;
    CGFloat tabBarStartingY = viewSize.height;
    CGFloat contentViewHeight = viewSize.height;
    CGFloat tabBarHeight = CGRectGetHeight([[weakSelf tabBar] frame]);

    if (!tabBarHeight) {
        tabBarHeight = 49;
    }

    if (!hidden) {
        tabBarStartingY = viewSize.height - tabBarHeight;
        if (![[weakSelf tabBar] isTranslucent]) {
            contentViewHeight -= ([[weakSelf tabBar] minimumContentHeight] ?: tabBarHeight);
        }
        [[weakSelf tabBar] setHidden:NO];
    }

    [[weakSelf tabBar] setFrame:CGRectMake(0, tabBarStartingY, viewSize.width, tabBarHeight)];
    if ([[UIDevice currentDevice] systemVersion].floatValue >= 7.0 && [[UIDevice currentDevice] systemVersion].floatValue < 8.0) {
        [[weakSelf contentView] setFrame:[UIScreen mainScreen].bounds];
    }else{
        [[weakSelf contentView] setFrame:CGRectMake(0, 0, viewSize.width, contentViewHeight)];
    }
};

void (^completion)(BOOL) = ^(BOOL finished){
    if (hidden) {
        [[weakSelf tabBar] setHidden:YES];
    }
};

if (animated) {
    [UIView animateWithDuration:0.24 animations:block completion:completion];
} else {
    block();
    completion(YES);
}

}

you have fix this bug ,but the other bug come appear . The fram is not correct .

would you have better ideas？

这个bug，ios8已经完美解决了这个bug。但是毕竟不开源，我似乎找到了原因，问题就出现在pop这个方法里，苹果估计是在ios8修改了这个方法，所以要fix这个bug就要重写这个pop方法，或者你设置隐藏tabbar的时候animation改为NO就没有这个问题了。

虽然可能不是我需要的效果 但是还是谢谢你了

iOS8 侧滑 会crash, POP 也可能crash,这个有解决么？
