您好,在我的应用程序中,我将一些 uiButtons 作为子视图添加到如下图所示的视图中。 替代文字 http://img99.imageshack.us/img99/5244/portraitc.png
当用户横向旋转手机时,视图和按钮的位置必须更改为: alt text http://img193.imageshack.us/img193/5931/landscapeq.png
最初,当视图处于纵向模式时,按钮会响应触摸。如果我倾斜手机按钮移动,一切看起来都像第二张图片一样,按钮响应触摸。如果我将手机倾斜回纵向模式,按钮会向后移动,它们看起来不错,但对触摸没有反应。如果我改回横向按钮工作...
我的按钮是这样创建的:
nextNewsP = [[UIButton alloc] initWithFrame:CGRectMake([[UIScreen mainScreen] bounds].size.width - 40, 10, 25, 25)];
[nextNewsP setImage:[UIImage newImageFromResource:@"next_arrow.png"] forState:UIControlStateNormal];
[nextNewsP addTarget:self action:@selector(nextNewsAction:) forControlEvents:UIControlEventTouchUpInside];
[nextNewsP setShowsTouchWhenHighlighted:TRUE];
[bottomTools addSubview:nextNewsP];
[nextNewsP release];
previousNewsP = [[UIButton alloc] initWithFrame:CGRectMake([[UIScreen mainScreen] bounds].size.width - 85, 10, 25, 25)];
[previousNewsP setImage:[UIImage newImageFromResource:@"previous_arrow.png"] forState:UIControlStateNormal];
[previousNewsP addTarget:self action:@selector(previousNewsAction:) forControlEvents:UIControlEventTouchUpInside];
[previousNewsP setShowsTouchWhenHighlighted:TRUE];
[bottomTools addSubview:previousNewsP];
[previousNewsP release];
bottomTools 是一个视图,也作为子视图添加,如下所示:
[self.view addSubview:bottomTools];
[bottomTools release];
我的 shouldAutorotateToInterfaceOrientation 函数如下所示:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
[UIView beginAnimations:@"moveViews" context: nil];
if(interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
{
NSLog(@"set frames for portrait");
closeView.frame = CGRectMake([[UIScreen mainScreen] bounds].size.width - 30, 2, 23, 25);
newsInfo.frame = CGRectMake(10, 10, [[UIScreen mainScreen] bounds].size.width - 10, 22);
internetActivityIndicator.frame = CGRectMake([[UIScreen mainScreen] bounds].size.width - 55, 5, 18, 18);
industryLabel.frame = CGRectMake([[UIScreen mainScreen] bounds].size.width/2.0 - [industryTitle sizeWithFont:[UIFont systemFontOfSize:14]].width/2, 3, [industryTitle sizeWithFont:[UIFont systemFontOfSize:14]].width, 22);
bottomTools.frame = CGRectMake(0, [[UIScreen mainScreen] bounds].size.height-40, [[UIScreen mainScreen] bounds].size.width, 40);
nextNewsP.frame = CGRectMake([[UIScreen mainScreen] bounds].size.width - 40, 10, 25, 25);
previousNewsP.frame = CGRectMake([[UIScreen mainScreen] bounds].size.width - 85, 10, 25, 25);
}
else
{
NSLog(@"set frames for landscape");
closeView.frame = CGRectMake([[UIScreen mainScreen] bounds].size.height - 30, 2, 23, 25);
newsInfo.frame = CGRectMake(10, 10, [[UIScreen mainScreen] bounds].size.height - 10, 22);
internetActivityIndicator.frame = CGRectMake([[UIScreen mainScreen] bounds].size.height - 55, 5, 18, 18);
industryLabel.frame = CGRectMake([[UIScreen mainScreen] bounds].size.height/2.0 - [industryTitle sizeWithFont:[UIFont systemFontOfSize:14]].width/2, 3, [industryTitle sizeWithFont:[UIFont systemFontOfSize:14]].width, 22);
bottomTools.frame = CGRectMake(0, [[UIScreen mainScreen] bounds].size.width-40, [[UIScreen mainScreen] bounds].size.height, 40);
nextNewsP.frame = CGRectMake([[UIScreen mainScreen] bounds].size.height - 40, 10, 25, 25);
previousNewsP.frame = CGRectMake([[UIScreen mainScreen] bounds].size.height - 85, 10, 25, 25);
}
[UIView commitAnimations];
return YES;
}
你有过类似的问题吗?提前谢谢你,索林
