如何集成ELCImagePickerController？

Question

我在我的应用中使用了ELCImagePickerController。根据从Github下载的演示，我使用的代码是

ELCAlbumPickerController *albumController = [[ELCAlbumPickerController alloc]    initWithNibName:@"ELCAlbumPickerController" bundle:[NSBundle mainBundle]];    

ELCImagePickerController *elcPicker = [[ELCImagePickerController alloc] initWithRootViewController:albumController];

[albumController setParent:elcPicker];

[elcPicker setDelegate:self];

ELCImagePickerDemoAppDelegate *app = (ELCImagePickerDemoAppDelegate *)[[UIApplication sharedApplication] delegate];

[app.viewController presentModalViewController:elcPicker animated:YES];

[elcPicker release];
[albumController release];

现在它不能工作了，因为ELCImagePickerDemoAppDelegate不是我的application.So的AppDelegate，应该是正确的代码来将这个图像选择器集成到我的应用程序中。我还尝试将UIViewController子类添加到我的应用程序中并调用

[self presentModalViewController:elcPicker animated:YES];

但这不会显示选取器并记录一条消息

deallocing ELCImagePickerController

有人能给我指引正确的方向吗？

Answer 1

只需按如下所示操作

在.h文件中添加以下内容

#import "ELCImagePickerController.h"

并符合ELCImagePickerControllerDelegate协议

在.m文件中，在顶部添加以下内容

#import "ELCImagePickerController.h"
#import "ELCAlbumPickerController.h"

并在要显示选取器的位置添加以下代码

ELCAlbumPickerController *albumController = [[ELCAlbumPickerController alloc] initWithNibName:@"ELCAlbumPickerController" bundle:[NSBundle mainBundle]];    
    ELCImagePickerController *elcPicker = [[ELCImagePickerController alloc] initWithRootViewController:albumController];
    [albumController setParent:elcPicker];
    [elcPicker setDelegate:self];
    [self presentModalViewController:elcPicker animated:YES];

，还包括所需的协议方法。

Answer 2

尽量不要使用initWithNibName...

#import "ELCImagePickerController.h"
#import "ELCAlbumPickerController.h"

ELCAlbumPickerController *albumController = [[ELCAlbumPickerController alloc] init];
    ELCImagePickerController *elcPicker = [[ELCImagePickerController alloc] initWithRootViewController:albumController];
[albumController setParent:elcPicker];
    [elcPicker setDelegate:self];
    [self presentModalViewController:elcPicker animated:YES];
