UIMenuController自定义项

我认为这是少数几个你想子类化的例子之一 UITextView 做点什么 项目。

从我的 TestViewController.m

@implementation TestViewController

- (void) doSomething: (id) sender
{
    NSLog(@"Doing something");
}

- (void) viewDidLoad
{
    UIMenuController *menuController = [UIMenuController sharedMenuController];
    UIMenuItem *item = [[[UIMenuItem alloc] initWithTitle: @"Do Something"
        action: @selector(doSomething:)] autorelease];
    [menuController setMenuItems: [NSArray arrayWithObject: item]];
}

@end

MyTextView.h :

//  MyTextView.h

#import <UIKit/UIKit.h>

@interface MyTextView :UITextView {

}

@end

代码 MyTextView.m

//  MyTextView.m

#import "MyTextView.h"

@implementation MyTextView

- (BOOL) canPerformAction:(SEL)action withSender:(id)sender
{
    return NO;
}

@end
