Mat*_*uif 4 uinavigationbar uitoolbar ios ios7
在ios7上,许多应用程序(Apple Messages,Facebook Messenger,Calendar)都会在UINavigationBar下显示视图,通常会显示标准动画.由于看起来非常标准并且使用UIToolBar看起来很多,我一直在寻找实现它的标准方法但却找不到任何东西.
有没有更好的方法将UIToolBar添加到UINavigationBar?

你应该遵循这个简单的方法.
添加UIToolBar这样的.
UIBarButtonItem *flexiableItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
UIBarButtonItem *item1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:nil];
UIBarButtonItem *item2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:nil];
NSArray *items = [NSArray arrayWithObjects:item1, flexiableItem, item2, nil];
self.toolBar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, -44, self.view.frame.size.width, 44)];
[self.toolBar setItems:items];
self.toolBar.tintColor = [UIColor whiteColor];
self.toolBar.barTintColor = [UIColor colorWithRed:0.6 green:0.1 blue:0.2 alpha:1];
[self.contentView addSubview:self.toolBar];
Run Code Online (Sandbox Code Playgroud)在顶部导航项上添加菜单按钮
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Menu" style:UIBarButtonItemStyleBordered target:self action:@selector(toggleMenu:)];
Run Code Online (Sandbox Code Playgroud)现在实现toggleMenu功能.添加BOOL变量以跟踪移动.
if(!moved) {
[UIView animateWithDuration:0.5 animations:^{
self.toolBar.alpha = 1;
self.toolBar.frame = CGRectMake(0, 0, self.view.frame.size.width, 44);
}];
moved = YES;
}else {
[UIView animateWithDuration:0.5 animations:^{
self.toolBar.alpha = 1;
self.toolBar.frame = CGRectMake(0, -44, self.view.frame.size.width, 44);
}];
moved = NO;
}
