UIAlertView未响应UIAlertViewDelegate

Question

我正在使用iPhone (MobileSubstrate插件)的徽标，以及我的.h文件

@interface MyClass : NSObject <UIAlertViewDelegate>

和

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if(buttonIndex == 0) {

谢谢。

编辑:这是我得到的；

#import "Tweak.h"

%hook ASApplicationPageHeaderView

- (void)_showPurchaseConfirmation {
    UIAlertView *alert = [[UIAlertView alloc] init];
    [alert setTitle:@"title"];
    [alert setMessage:@"message"];
    [alert setDelegate:self];
    [alert addButtonWithTitle:@"button 1"];
    [alert addButtonWithTitle:@"continue"];
    [alert show];
    [alert release];
}

- (void)alertView:(UIAlertView *)alert clickedButtonAtIndex:(NSInteger)buttonIndex {    
    if (buttonIndex == 0) {  //also tried (UIAlertView *)alertView
        UIAlertView *lol = [[UIAlertView alloc] init];
        [lol setTitle:@"button 1"];
        [lol setMessage:@"button 1"];
        [lol setDelegate:self];
        [lol addButtonWithTitle:@"lol"];
        [lol show];
        [lol release];
    } else {
        %orig;
    }
}

%end

Answer 1

在某些情况下，您很可能需要将您的类注册为委托，方法如下：

 [yourAlertViewObject setDelegate:self];

正如UIAlertViewDelegate Protocol Reference文档所说(强调我的)：

如果您添加自己的按钮或自定义警报视图的行为，请实现符合此协议的委托来处理相应的委托消息。使用警报视图的delegate属性指定一个应用程序对象作为委派。

Answer 2

在该类中定义您的警报，并将警报委托声明为self，希望它开始对您起作用

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Alert View "
                      " 
                                                message:@"Would you like to do something?"
                                               delegate:self 
                                      cancelButtonTitle:@"Cancel"
                                      otherButtonTitles:@"Button1", @"Button2", nil];
[alert show];
[alert release];

Answer 3

您只需将%new放在alertView委托的前面：

 %new
 -(void) alertView:...
