1. UINavigationController

cocos2d-x 启动后会调用AppController:

// main.m

#importint main(int argc, char *argv[]) {

@autoreleasepool {

return UIApplicationMain(argc, argv, nil, @"AppController");

}

}

在AppController完成启动的过程中，创建了RootViewController，绑定GLView:

// Use RootViewController manage CCEAGLView

_viewController = [[RootViewController alloc] initWithNibName:nil bundle:nil];

_viewController.wantsFullScreenLayout = YES;

_viewController.view = eaglView;

// Set RootViewController to window

if ([[UIDevice currentDevice].systemVersion floatValue] < 6.0) {

// warning: addSubView doesn't work on iOS6

[_window addSubview: _viewController.view];

} else {

// use this method on ios6

[_window setRootViewController:_viewController];

}

可以创建一个UINavigationController作为_window的rootViewController，将_viewController用push的方式放到nav中。如需调用原生的UIViewController，使用一样的方法push/pop即可。

尚未解决的问题是：如果我只是在GLView的界面上增加一个原生API的显示控件，两个view是层叠的效果，上层（即原生显示控件）部分透明地改在GLView上，这个方法需要改进。测试结果是，上层只有一个加了局部白色的UIDatePicker时，余下的全是黑色。

2. RootViewController

我异想天开地自定义了一个UIView，就是之前白底黑字的UIDatePicker，通过addSubView的方式直接将其加到RootViewController的view上。确实可以看见了，但是，UIDatePicker根本就不相应点触，而这个UIView就是个透明盖子，底下的GLView上的点触丝毫没受影响。

然后，我用UIViewController替换原来的UIView，把白底黑子的UIDatePicker加到这个VC的view上，Picker可以转了，但是GLView还是继续相应点触。加到_window就屏蔽掉了GLView的点触。

当当当当！正经的来了！文字后面再补吧。点我链接

// AppController.mm

+ (void) showUIViewController:(UIViewController *)controller

{

if (IOS_8_OR_LATER)

{

controller.modalPresentationStyle = UIModalPresentationOverCurrentContext;

}

else

{

s_pCurrentViewController.modalPresentationStyle = UIModalPresentationCurrentContext;

}

[s_pCurrentViewController presentViewController:controller animated:YES completion:{}];

}

调用的地方

DatePicker *dp = [[DatePicker alloc] init];

[AppController showUIViewController:dp];

// DatePicker.h

#import [Foundation/Foundation.h]

#import [UIKit/UIKit.h]

@interface DatePicker : UIViewController

@property (nonatomic, retain) UIView *bg;

@property (nonatomic, retain) UIDatePicker *dp;

@property (nonatomic, retain) UIButton *bt;

@end

// DatePicker.mm

#import "DatePicker.h"

#include "AppController.h"

@implementation DatePicker

@synthesize bg;

@synthesize dp;

@synthesize bt;

- (void) viewDidLoad

{

bg = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 300, 200)];

[bg setBackgroundColor:[UIColor whiteColor]];

[self.view addSubview:bg];

dp = [[UIDatePicker alloc]initWithFrame:CGRectMake(0, 0, 300, 200)];

[dp setDatePickerMode:UIDatePickerModeDate];

[self.view addSubview:dp];

bt = [UIButton buttonWithType:UIButtonTypeRoundedRect];

bt.frame = CGRectMake(10 , 10, 75, 44);

[bt setTitle:@"完成" forState:UIControlStateNormal];

[self.view addSubview:bt];

}

- (void) dealloc

{

[dp release];

[bt release];//[UIButton buttonWithType:UIButtonTypeCustom]之类的不需要release的

[bg release];

[super dealloc];

}

@end
