Iphone IB行动表与程序化行动表

大家好

我正在尝试实现Nate Weinders的“ShareKit”框架。一切顺利，直到最后一步

我在Interface Builder中设置了一个名为“shareBtn”的通用操作按钮

在我的.h中，我有：

-(IBAction)shareBtn;

在my.m中，我设置了一个通用（工作）UIActionSheet：

我将ShareKit框架拉到顶部：#导入“SHK.h”

我的按钮有：

 -(IBAction)shareBtn {
         UIActionSheet *actionsheet = [[UIActionSheet alloc] 
                                       initWithTitle:@"Which do you prefer?"
                                       delegate:self 
                                       cancelButtonTitle:@"Cancel" 
                                       destructiveButtonTitle:@"Destuctive Button" 
                                       otherButtonTitles:@"Button 1", @"Button 2", @"Button 3", nil
                                       ];
         [actionsheet showInView:[self view]];
         [actionsheet release];

}

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
    NSLog(@"button %i clicked", buttonIndex );
}

这一切都很好。现在，根据ShareKit的安装页面上的说明，我将把下面的代码放到ShareKit框架中，使actionsheet挂钩：

- (void)myButtonHandlerAction
{
    // Create the item to share (in this example, a url)
    NSURL *url = [NSURL URLWithString:@"http://getsharekit.com"];
    SHKItem *item = [SHKItem URL:url title:@"ShareKit is Awesome!"];

    // Get the ShareKit action sheet
    SHKActionSheet *actionSheet = [SHKActionSheet actionSheetForItem:item];

    // Display the action sheet
    [actionSheet showFromToolbar:navigationController.toolbar];
}

这看起来相当直截了当，我对语法进行了一些研究（使用self.toolbar等），我只是在努力理解这个概念以及我所缺少的东西。我阅读了关于这方面的iOS文档，参考了我仅有的几本书，并进行了大量的在线搜索

只是希望能看到一个明显的错误或帮助我一点

多谢各位

以下是我尝试的内容和错误：

第一次尝试

 -(IBAction)shareBtn {
    // Create the item to share (in this example, a url)
    NSURL *url = [NSURL URLWithString:@"http://getsharekit.com"];
    SHKItem *item = [SHKItem URL:url title:@"ShareKit is Awesome!"];

    // Get the ShareKit action sheet
    SHKActionSheet *actionSheet = [SHKActionSheet actionSheetForItem:item];

    // Display the action sheet
    [actionSheet showFromToolbar:navigationController.toolbar];
}

错误：“navigationController未声明”

此外： 我现在正在阅读“大书呆子指南——iPhone编程”。 作为学习的一种方式，我尝试应用我一直在学习的一些概念（其中一些稍微超出我目前的知识）。我大致了解具体的错误，但不知道如何实施此操作

让我困惑的是，这张行动单与我所学的第一种方法配合得非常好。我现在正试图通过引入ShareKit框架并使其执行来扩展这些知识。这看起来很直截了当，我真的很沮丧

这是ShareKit安装（上面写着“三行简单的代码”） 步骤4： 我让它工作了

最终代码：

-(IBAction)shareBtn {
    // Create the item to share (in this example, a url)
    NSURL *url = [NSURL URLWithString:@"http://getsharekit.com"];
    SHKItem *item = [SHKItem URL:url title:@"ShareKit is Awesome!"];

    // Get the ShareKit action sheet
    SHKActionSheet *actionSheet = [SHKActionSheet actionSheetForItem:item];

    // Display the action sheet
    [actionSheet showInView:[self view]];
    [actionSheet release];
}

给我带来的是两件愚蠢的事情，一件是我在showInView或发行版的行动表中没有大写“S”。第二个是使用showInView:[自我查看]；而不是.toolbar方法

谢谢，我知道只要一点提示就能帮我调试。

还有，如果有人看到这个。删除行：“[actionSheet release]”；如果有人看到此情况，也可以删除行：“[actionSheet release]”；
