好吧,这似乎是荒谬的,但我在回答自己:P
Ok… it seems absurd, but I'm answering myself :P
我设法使工作(finaly!),我发现我正在以BAAAAD方式管理viewController,所以我改变了协调控制器中的一些代码:
I managed to make it work (finaly!) and I found I was managing the viewControllers in a BAAAAD way, so, I changed some code in the coordinating controller:
首先,我不有一个真正的mainViewController与NIB和stuf没有更多...
First, I don't have a "real" mainViewController with NIBs and stuf no more…
旧初始化
- (void) initialize{
C6Log(@"");
[self checkDevice];
_mainVC = [C6MainViewController initWithDevice:device];
_activeVC = _mainVC;
[self checkLanguage];
[self chooseFirstView];
}
新初始化
- (void) initialize{
C6Log(@"");
[self checkDevice];
[self checkLanguage];
[self chooseFirstView];
}
checkDevice 验证是iPhone还是iPad我可以选择正确的NIB。
checkDevice verifies if it's iPhone or iPad, so I can choose the right NIB.
checkLanguage 检查[NSUserDefaults standardUserDefaults]的语言
checkLanguage checks the [NSUserDefaults standardUserDefaults] for the language
Finaly,我叫selectFirstView:
Finaly, I call chooseFirstView:
OLD chooseFirstView
-(void) chooseFirstView{
// If a language was not setted, go to language settings view
if (!language) {
C6Log(@"Going to Language Settings");
C6LanguageSettingsViewController *languageVC = [C6LanguageSettingsViewController initWithDevice:device];
[_mainVC.view addSubview:languageVC.view];
}
else {
C6Log(@"Going to User Settings", language);
C6AccountSettingsViewController *accountVC = [C6AccountSettingsViewController initWithDevice:device];
[_mainVC.view addSubview:accountVC.view];
}
}
新的selectFirstView p>
NEW chooseFirstView
-(void) chooseFirstView{
// If a language was not setted, go to language settings view
_activeVC = [[UIViewController alloc] init];
UIImage *bgImage = [UIImage imageNamed:@"bg.png"];
UIImageView *bgView = [[UIImageView alloc] initWithImage:bgImage];
[_activeVC.view addSubview:bgView];
if (!language) {
C6Log(@"Going to Language Settings");
languageVC = [C6LanguageSettingsViewController initWithDevice:device];
[_activeVC.view addSubview:languageVC.view];
}
else {
C6Log(@"Going to User Settings", language);
accountVC = [C6AccountSettingsViewController initWithDevice:device];
[_activeVC.view addSubview:accountVC.view];
}
}
这个很大的变化是WHEN和如何启动_activeVC ...和_languageVC和_accountVC现在都是全局变量的事实。
The big change is WHEN and HOW I initiated the _activeVC… AND the fact that both _languageVC and _accountVC are now global variables.
嗯,这个改变之后,NIB按钮调用了IBAction方法:它是文件的所有者和协调控制器
Well, after this changes, the NIB button call both IBAction methods: it's file's owner and the coordinating controller.
使用这种模式的另一个重要事情是如何从一个视图切换到另一个视图,而不会发生爆炸性的iOS设备内存...这里是如何在协调控制器内进行的:
Another BIG thing about using this kind of pattern is how to change from one view to another without explode iOS device memory… here's how I do it inside the coordinating controller:
- (IBAction) requestViewChangeByObject:(id)object {
int buttonTag = [object tag]; // dividend
int viewTag = buttonTag / divisor; // quotient
int actionTag = buttonTag - (divisor * viewTag); // remainder
C6Log(@"ViewTag: %d", viewTag);
switch (viewTag) {
case LanguageTags:{
C6Log(@"LanguageTags - button %d", actionTag);
accountVC = [C6AccountSettingsViewController initWithDevice:device];
UIView *fromView = languageVC.view;
UIView *toView = accountVC.view;
[self switchFrom:fromView To:toView usingAnimation:AnimationPushFromRigh];
}
break;
case AccountTags:{
C6Log(@"AccountTags - button %d", actionTag);
switch (actionTag) {
case 0:{
C6Log(@"Go back");
languageVC = [C6LanguageSettingsViewController initWithDevice:device];
UIView *fromView = accountVC.view;
UIView *toView = languageVC.view;
[self switchFrom:fromView To:toView usingAnimation:AnimationPushFromLeft];
}
break;
default:
break;
}
}
break;
default:
break;
}
}
在开始的方法中,我做了很多数学...我创建了一个模式,每个NIB应该有100个倍数开始的标签...所以,语言从0开始,帐户为100 .........
In the beginning of the method, I do a lot of math… I "created" a pattern where each NIB should have it's tags beginning with 100 multiples… so, language begins with 0, account with 100………
#define divisor 100
#define LanguageTags 0
#define AccountTags 1
然后,我从一个视图更改为另一个视图的方式就在那里:
Then, the way I change from one view to another is right there:
-(void) switchFrom:(UIView*) fromView To:(UIView*) toView usingAnimation:(int) animation{
C6Log(@"");
/*************** SET ALL DEFAULT TRANSITION SETTINGS ***************/
// Get the current view frame, width and height
CGRect pageFrame = fromView.frame;
CGFloat pageWidth = pageFrame.size.width;
// Create the animation
[UIView beginAnimations:nil context:nil];
// Create the delegate, so the "fromView" is removed after the transition
[UIView setAnimationDelegate: fromView];
[UIView setAnimationDidStopSelector:@selector(removeFromSuperview)];
// Set the transition duration
[UIView setAnimationDuration: 0.4];
// Add the "toView" as subview of "fromView" superview
[fromView.superview addSubview:toView];
switch (animation) {
case AnimationPushFromRigh:{
// Position the "toView" to the right corner of the page
toView.frame = CGRectOffset(pageFrame, pageWidth,0);
// Animate the "fromView" to the left corner of the page
fromView.frame = CGRectOffset(pageFrame, -pageWidth,0);
// Animate the "toView" to the center of the page
toView.frame = pageFrame;
// Animate the "fromView" alpha
fromView.alpha = 0;
// Set and animate the "toView" alpha
toView.alpha = 0;
toView.alpha = 1;
// Commit the animation
[UIView commitAnimations];
}
break;
case AnimationPushFromLeft:{
// Position the "toView" to the left corner of the page
toView.frame = CGRectOffset(pageFrame, -pageWidth,0);
// Animate the "fromView" to the right corner of the page
fromView.frame = CGRectOffset(pageFrame, pageWidth,0);
// Animate the "toView" to the center of the page
toView.frame = pageFrame;
// Animate the "fromView" alpha
fromView.alpha = 0;
// Set and animate the "toView" alpha
toView.alpha = 0;
toView.alpha = 1;
// Commit the animation
[UIView commitAnimations];
}
break;
default:
break;
}
}
我真的希望这有助于谁试图使用这个协调控制器模式:P
I really hope this helps who's trying to use this coordinating controller pattern :P
