我在XCode中创建了一个Viewcontroller,一切正常。当有电话呼叫时,呼叫状态栏中的按钮会按下视图底部的按钮" DOWN"由于我在通话期间无法点击按钮。
我想知道即使拨打电话,如何将按钮保持在底部,同一位置。我尝试了几种方法对我没用。
- (void)statusBarFrameWillChange:(NSNotification*)notification {
NSValue* rectValue = [[notification userInfo] valueForKey:UIApplicationStatusBarFrameUserInfoKey];
CGRect newFrame;
[rectValue getValue:&newFrame];
CGRect fixedFrame = bottomBar.frame;
fixedFrame.origin.y = fixedFrame.origin.y - newFrame.size.height; //Keep the Y position as it is
bottomBar.frame = fixedFrame;
NSLog(@"statusBarFrameWillChange: newSize %f, %f, %f", fixedFrame.origin.y, newFrame.size.width, newFrame.size.height);
}
- (void)statusBarFrameChanged:(NSNotification*)notification {
NSValue* rectValue = [[notification userInfo] valueForKey:UIApplicationStatusBarFrameUserInfoKey];
CGRect oldFrame;
[rectValue getValue:&oldFrame];
CGRect fixedFrame = bottomBar.frame;
fixedFrame.origin.y = fixedFrame.origin.y + oldFrame.size.height;
bottomBar.frame = fixedFrame;
NSLog(@"statusBarFrameChanged: oldSize %f, %f, %f", fixedFrame.origin.y, oldFrame.size.width, oldFrame.size.height);
}

使用自动布局,请务必设置Bottom Space
