我正在创建一个包含UINavigationBar
和UITabBar
的视图。我在标签栏上添加了一个按钮,点击按钮,我隐藏标签栏并在底部显示工具栏。我的代码是针对当前以及之前的iOS版本编写的。我在iOS7中使用此代码self.edgesForExtendedLayout = UIRectEdgeNone;
这是我的代码:
- (void)hideTabBar {
UITabBar *tabBar = self.tabBarController.tabBar;
UIView *parent = tabBar.superview; // UILayoutContainerView
UIView *content = [parent.subviews objectAtIndex:0]; // UITransitionView
UIView *window = parent.superview;enter code here
[UIView animateWithDuration:0.5
animations:^{
CGRect tabFrame = tabBar.frame;
tabFrame.origin.y = CGRectGetMaxY(window.bounds);
tabBar.frame = tabFrame;
// CGRect contentFrame = content.frame;
// contentFrame.size.height -= tabFrame.size.height;
content.frame = window.bounds;
}];
if ([[[UIDevice currentDevice] systemVersion] intValue] < 7.0)
{
CGRect frame = tbl_AllFiles.frame;
frame.size.height -=tabBar.frame.size.height;
tbl_AllFiles.frame = frame;
}
}
- (void)showTabBar {
UITabBar *tabBar = self.tabBarController.tabBar;
UIView *parent = tabBar.superview; // UILayoutContainerView
UIView *content = [parent.subviews objectAtIndex:0]; // UITransitionView
UIView *window = parent.superview;
if ([[[UIDevice currentDevice] systemVersion] intValue] < 7.0)
{
CGRect frame = tbl_AllFiles.frame;
frame.size.height +=tabBar.frame.size.height;
tbl_AllFiles.frame = frame;
}
[UIView animateWithDuration:0.5
animations:^{
CGRect tabFrame = tabBar.frame;
tabFrame.origin.y = CGRectGetMaxY(window.bounds) - CGRectGetHeight(tabBar.frame);
tabBar.frame = tabFrame;
CGRect contentFrame = content.frame;
contentFrame.size.height -= tabFrame.size.height;
content.frame = contentFrame;
}];
}
- (void)loadToolBar {
toolbar = [UIToolbar new];
toolbar.barStyle = UIBarStyleBlackTranslucent;
moveButton = [UIButton buttonWithType:UIButtonTypeCustom];
[moveButton setFrame:CGRectMake(10, 10, 120, 25)];
[moveButton setBackgroundColor:[UIColor redColor]];
[moveButton setTitle:@"Move" forState:UIControlStateNormal];
[moveButton addTarget:self action:@selector(moveFile_Folder:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *moveItem = [[[UIBarButtonItem alloc] initWithCustomView:moveButton] autorelease];
moveItem.style = UIBarButtonItemStyleBordered;
NSArray *items = [NSArray arrayWithObjects:moveItem, nil];
toolbar.items = items;
[toolbar sizeToFit];
CGFloat toolbarHeight = [toolbar frame].size.height;
CGRect mainViewBounds = self.view.bounds;
if ([[[UIDevice currentDevice] systemVersion] intValue] < 7.0)
{
[toolbar setFrame:CGRectMake(CGRectGetMinX(mainViewBounds),
CGRectGetMinY(mainViewBounds) + CGRectGetHeight(mainViewBounds) - (toolbarHeight),
CGRectGetWidth(mainViewBounds),
toolbarHeight)];
}
else
{
[toolbar setFrame:CGRectMake(CGRectGetMinX(mainViewBounds),
CGRectGetMinY(mainViewBounds) + CGRectGetHeight(mainViewBounds),
CGRectGetWidth(mainViewBounds),
toolbarHeight)];
}
[self.view addSubview:toolbar];
[toolbar bringSubviewToFront:self.view];
}
我的问题是在按钮上单击hideTabBar并调用loadToolBar方法。一切都运行正常,除了我的按钮现在在工具栏上无法点击。 请帮帮我。
答案 0 :(得分:0)
在viewdidload中将此行添加到viewcontroller,
self.view.frame = [UIScreen mainScreen].bounds;
希望有所帮助
