1. UINavigationController
cocos2d-x 啟動(dòng)后會(huì)調(diào)用AppController:
// main.m
#importint main(int argc, char *argv[]) {
@autoreleasepool {
return UIApplicationMain(argc, argv, nil, @"AppController");
}
}
在AppController完成啟動(dòng)的過(guò)程中，創(chuàng)建了RootViewController，綁定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];
}
可以創(chuàng)建一個(gè)UINavigationController作為_window的rootViewController，將_viewController用push的方式放到nav中。如需調(diào)用原生的UIViewController，使用一樣的方法push/pop即可。
尚未解決的問(wèn)題是：如果我只是在GLView的界面上增加一個(gè)原生API的顯示控件，兩個(gè)view是層疊的效果，上層（即原生顯示控件）部分透明地改在GLView上，這個(gè)方法需要改進(jìn)。測(cè)試結(jié)果是，上層只有一個(gè)加了局部白色的UIDatePicker時(shí)，余下的全是黑色。
2. RootViewController
我異想天開地自定義了一個(gè)UIView，就是之前白底黑字的UIDatePicker，通過(guò)addSubView的方式直接將其加到RootViewController的view上。確實(shí)可以看見了，但是，UIDatePicker根本就不相應(yīng)點(diǎn)觸，而這個(gè)UIView就是個(gè)透明蓋子，底下的GLView上的點(diǎn)觸絲毫沒受影響。
然后，我用UIViewController替換原來(lái)的UIView，把白底黑子的UIDatePicker加到這個(gè)VC的view上，Picker可以轉(zhuǎn)了，但是GLView還是繼續(xù)相應(yīng)點(diǎn)觸。加到_window就屏蔽掉了GLView的點(diǎn)觸。
當(dāng)當(dāng)當(dāng)當(dāng)！正經(jīng)的來(lái)了！文字后面再補(bǔ)吧。點(diǎn)我鏈接
// 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:{}];
}
調(diào)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]之類的不需要release的
[bg release];
[super dealloc];
}
@end
