的MKMapView不正确转换 [英] MKMapView not transitioning properly

问题描述

我有一个作为的MKMapView名为 MAINVIEW 另一个的UIView子视图。如果我我的过渡 MAINVIEW 在y轴带：

I've a MKMapView as a child view of another UIView called mainView. If I transition my mainView on the y-axis with:

[UIView animateWithDuration:0.3 delay:0.0 options:UIViewAnimationOptionCurveLinear animations:^{
    CGRect frame = self.mainView.frame;
    frame.origin.y += 100.0f;
    self.mainView.frame = frame;
} completion:nil];

那么 MAINVIEW 和它所有的子视图很好100点，向下转换屏幕除了的MKMapView，它保持完全在原来的位置。

then the mainView and all it's subviews nicely transition down the screen by 100 points, except of the MKMapView, which stays exactly at the original position.

于是，我就另一项实验中，也感动 frame.origin.y 中的MKMapView，然后实际的移动地图视图，而不是与其他意见的同步（它有轻微的延迟）。

So I tried another experiment and also moved the frame.origin.y of the MKMapView, which then actual moves the map view, but not synchronized with the other views (it has a slight delay).

任何一个想法，这是为什么？我认为，因为的MKMapView不是直接的UIView 子类。有没有办法来解决这个问题？

Anyone an idea why that is? I assume because MKMapView is not a direct UIView subclass. Is there a way to fix this behavior?

推荐答案

固定。问题是父的 autoresizesSubviews 属性的UIView 这是默认设置为是，并导致与的MKMapView 。设置 autoresizesSubviews 到 NO 使得它像一个魅力的工作： - ）

Fixed. The problem was the autoresizesSubviews property of the parent UIView which was set to YES by default and causes a strange behavior with the MKMapView. Setting autoresizesSubviews to NO makes it work like a charm :-)
