Instead of create IBOutlet, you have to make IBActionto directly get click event
而不是创建IBOutlet，你必须IBAction直接获取点击事件
check out this image...
看看这张图片...
This Is .mfile where i create IBActiondirectly
这是.m我IBAction直接创建的文件
and if you want to give click event programatically then follow @Nicolas Buquet answer
如果您想以编程方式提供点击事件，请按照@Nicolas Buquet 回答

Add this to your code:
将此添加到您的代码中：
[OkBtn addTarget:self action:@selector(okButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
and add this method to your class:
并将此方法添加到您的课程中：
- (void)okButtonTapped:(UIButton *)sender {
NSLog(@"Ok button was tapped: dismiss the view controller.");
}
The okButtonTapped:method will be called when you tap iside the button and remove your finger (the 'up" part).
okButtonTapped:当您点击按钮旁边并移开手指（“向上”部分）时，将调用该方法。

CreateIBActionforNSButton. And connect IBActionto the button.
创建IBAction的NSButton。并连接IBAction到按钮。
in interface file (.h) file write,
在接口文件 (.h) 文件中写入，
- (IBAction) okButtonAction : (id) sender;
and in your implementation file (.m)
并在您的实现文件 (.m) 中
- (IBAction) okButtonAction : (id) sender {
NSLog(@"OK Button action here");
}
