UIViewController新方法的使用(transitionFromViewController:toViewController:duration:options:animations:completion:)
2024-08-26 21:38:00
iOS5中，UIViewController新添加了几个方法：
- (void)addChildViewController:(UIViewController *)childController NS_AVAILABLE_IOS(5_0);
- (void) removeFromParentViewController NS_AVAILABLE_IOS(5_0); - (void)transitionFromViewController:(UIViewController *)fromViewController toViewController:(UIViewController *)toViewController duration:(NSTimeInterval)duration options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion NS_AVAILABLE_IOS(5_0); - (void)willMoveToParentViewController:(UIViewController *)parent NS_AVAILABLE_IOS(5_0);
- (void)didMoveToParentViewController:(UIViewController *)parent NS_AVAILABLE_IOS(5_0);
代码示例：
代码结构：
其中，MainViewController添加为window的rootViewController，FirstViewController、SecondViewController、ThirdViewController就是三个简单的controller，设置不同的背景色即可,MainViewController的xib文件如下图：
MainViewController的viewDidLoad方法实现如下：
- (void)viewDidLoad
{
[super viewDidLoad]; FirstViewController * firstController = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil];
[self addChildViewController:firstController]; SecondViewController * secondController = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];
[self addChildViewController:secondController]; ThirdViewController * thirdController = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil];
[self addChildViewController:thirdController]; [contentView addSubview:firstController.view];//用于显示其它controller的view
currentController = firstController;
}
三个button的响应方法如下：
- (IBAction)onButtonClick:(id)sender {
FirstViewController * firstController = self.childViewControllers[];
SecondViewController * secondController = self.childViewControllers[];
ThirdViewController * thirdController = self.childViewControllers[];
NSInteger tag = ((UIButton *) sender).tag;
if ((currentController == firstController && tag == ) || (currentController == secondController && tag == ) || (currentController == thirdController && tag == )) {
return;
}
UIViewController * oldController = currentController;
switch (tag) {
case :{
[self transitionFromViewController:currentController toViewController:firstController duration: options:UIViewAnimationOptionTransitionFlipFromLeft animations:^{} completion:^(BOOL finished) {
if (finished) {
currentController = firstController;
}
else {
currentController = oldController;
}
}];
break;
}
case : {
[self transitionFromViewController:currentController toViewController:secondController duration: options:UIViewAnimationOptionTransitionFlipFromTop animations:^{} completion:^(BOOL finished) {
if (finished) {
currentController = secondController;
}
else {
currentController = oldController;
}
}];
break;
}
case :{
[self transitionFromViewController:currentController toViewController:thirdController duration: options:UIViewAnimationOptionTransitionFlipFromBottom animations:^{} completion:^(BOOL finished) {
if (finished) {
currentController = thirdController;
}
else {
currentController = oldController;
}
}];
break;
}
default:
break;
}
}
