IBAction 无法识别的选择器发送到实例

我有一个简单的选项卡应用程序

我创建了一个 XIB 文件并将其分配给一个选项卡，当我触摸该选项卡时，它会准确地切换

添加了一个简单的 IBAction

我在 Tab1.h 中 -(IBAction)pleasebeep:(id)发件人；

在 Tab1.m

-(IBAction)pleasebeep:(id)sender 
{
    NSLog(@"honk");
}

界面生成器中，我创建了一个按钮并将其链接到所有者和操作“pleasebeep”，

它编译并启动。

当我单击按钮时，应用程序崩溃，并收到“-[UIViewController pleasebeep:]: 无法识别的选择器发送到实例 0x7b975c0 2011-10-06 04:32:25.648 FirstProject[8029:11903] * 由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“-[UIViewController pleasebeep:]：无法识别的选择器发送到实例 0x7b975c0” * 首先抛出调用堆栈： (0x12de082 0x146fd0a 0x12dfd1d 0x1244f70 0x1244d52 0x12dfef9 0x37c542 0x37c4da 0x421576 0x421a3f 0x420cfe 0x3a1810 0x3a1a36 0x388234 0x37ba29 0x1ece10d 0x12b21f5 0x12170a2 0x121598a 0x1214e34 0x1214d4b 0x1ecc9dd 0x1eccaa2 0x379a1b 0x2749 0x26c5) 终止调用抛出异常当前语言：auto;目前objective-c”

知道在哪里寻找问题吗？

原文

I have a simple tabbar app

I have created a XIB file and assigned it to a tab, and when I touch the tab, it accurately switches

I added a simple IBAction

in Tab1.h
-(IBAction)pleasebeep:(id)sender;

in Tab1.m

-(IBAction)pleasebeep:(id)sender 
{
    NSLog(@"honk");
}

In interface builder I have created a button and linked it to the Owner and action "pleasebeep"

It compiles and launches.

When I click the button, the app crashes and I get a "-[UIViewController pleasebeep:]: unrecognized selector sent to instance 0x7b975c0
2011-10-06 04:32:25.648 FirstProject[8029:11903] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIViewController pleasebeep:]: unrecognized selector sent to instance 0x7b975c0'

Any idea where to hunt for the problem?
