Question

- （void）setID :( long long） 是方法，我想检索传递的参数（整数）在警报视图中显示它。我是新手，请帮助我。如果可能的话，如何将这个论点传递给另一种方法 - （void）setSelectedID :( long long） ，如果这是我想传递参数的方法，我将如何在 Tweaks中执行此操作。 xm 文件。
任何帮助将不胜感激，谢谢这也可以使用Cycript吗？

此代码未经测试但我希望它可以提供帮助（假设setSelectedID:是您制作的方法）：

// Use parenthesis to avoid creating a duplicate definition of TheClassToHook
@interface TheClassToHook ()

// Put your new method definitions here

- (void)setSelectedID:(long long)passedID;

@end


%hook TheClassToHook

// This is the original method from TheClassToHook
- (void)setID:(long long)passedID {

    // Call your new method
    [self setSelectedID:passedID];

    // Create an NSString from the passed id,
    // it will be used to show it in the alert as a message
    NSString *msg = [NSString stringWithFormat:@"%lld", passedID];

    // Show an alert using UIAlertView, note that TheClassToHook should implement UIAlertViewDelegate
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"The passed id is..."
                                                    message:msg
                                                   delegate:self
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil];

    [alert show];

    // Optional: Make sure the memory used to allocate the alert and its message are released,
    // this may be unnecessary
    [alert release];
    [msg release];

    /* NOTE:
        UIAlertView is deprecated since iOS 8,
        if you don't want to target older iOS versions,
        you should consider using UIAlertController instead
    */

    // Call the original method with the original arguments
    %orig;
}


// Use the "%new" logos directive to implement a new method
%new
- (void)setSelectedID:(long long)passedID {
    // Your code
}

%end // close %hook

如果setSelectedID:是默认情况下存在的方法，您只需从@interface块中删除其定义及其在%hook块中的实现。

另外，由于我不使用Cycript，我不知道是否可以使用Cycript，抱歉。

使用theos挂钩到iOS中的实例方法并检索正在传递的参数
