怎样才能让我的UISwitch调用这个方法？(使用theos)

Question

如何让UISwitch调用此函数:打开时为https://ghostbin.com/paste/y2xrc，关闭时返回FALSE。(我正在使用theos编译)

(我将开关设置为在Messages.app (MobileSMS.app)中显示"CKTranscriptCollectionViewController“内部，现在我想让它在打开或关闭时执行某些操作，这就是我在上面的链接中发布的内容)。

#import <UIKit/UIKit.h>
#import <ChatKit/ChatKit.h>
#import <ChatKit/CKConversation.h>

@interface CKTranscriptCollectionViewController : UIViewController
@property (nonatomic, strong) UISwitch *mySwitch;
- (void)loadView;
@end

%hook CKTranscriptCollectionViewController

- (void)viewDidLoad {   
    %orig;
    UISwitch *mySwitch = [[UISwitch alloc] initWithFrame:CGRectMake(10, 10, 51, 31)];
    [mySwitch setOn:NO animated:YES];
    [self.view addSubview:mySwitch];
}

%end

Answer 1

对于UISwitch，您应该为UIControlEventValueChanged添加一个目标

[mySwitch addTarget:self action:@selector(switchToggle) forControlEvents:UIControlEventValueChanged];

代入你的目标并采取相应的行动。调用选择器时，您需要检查开关的值是什么。

Answer 2

您可以尝试这样做：

[yourSwitchObject addTarget:self action:@selector(generateLegendaryMessage:) forControlEvents:UIControlEventValueChanged]; 

- (void)generateLegendaryMessage:(id)sender 
{
    NSLog("Its gonna be legen...... wait for it ...... dary !!!!!!!");
}
