ios7中使用scrollview来横向滑动图片，自动产生偏移竖向的偏移问题

如图红色为scrollview的背景色，在scrollview上加了图片之后，总会有向下的偏移

设置contentOffset也不管用

在ios7中controller有个

automaticallyAdjustsScrollViewInsets属性，默认为YES

if (iOS7&&[self respondsToSelector:@selector(automaticallyAdjustsScrollViewInsets)]) {self.automaticallyAdjustsScrollViewInsets = NO;}

@property(nonatomic, assign) BOOL automaticallyAdjustsScrollViewInsets
Description	Specifies whether or not the view controller should automatically adjust its scroll view insets.
Default value isYES, which allows the view controller to adjust its scroll view insets in response to the screen areas consumed by the status bar, navigation bar, and toolbar or tab bar. Set toNOif you want to manage scroll view inset adjustments yourself, such as when there is more than one scroll view in the view hierarchy.
Availability	iOS (7.0 and later)
