如何研究iDevice？

Question

我正在尝试做一个应用程序，以重新启动和重启任何iDevice。我的代码在iOS模拟器中运行良好，但是在我的iDevice上什么也没有发生(是的，它被越狱了)。

下面是我的呼吸代码：

        if(system("killall SpringBoard"));

        if(system("killall -9 SpringBoard"));

        if (system([@ "reboot" UTF8String]));

        if ([[[UIDevice currentDevice] systemVersion] hasPrefix:@"2."])
            notify_post("com.apple.language.changed");

        if (system([@ "killall SpringBoard" UTF8String]));

下面是我的重启代码：

if (system([@ "reboot" UTF8String]));

respring只工作一次，然后停止工作：(

我的脚本：

#!/bin/sh

#  Script.sh
#  Respring

declare -a flags
[[ :${DYLD_INSERT_LIBRARIES}: == */MobileSubstrate.dylib: ]] && flags[${flags[@]}]=--substrate
exec "${C:-.}"/Respring "${flags[@]}" -- "$@" 2>>/tmp/Respring.log

这是我的alertView，用于在呼吸不起作用时使用BugReport重新启动和重新启动

示例

我将我的应用程序命名为Respring

在我的应用程序代码中，我有一个RespringViewController.h和RespringViewController.m

在ResringViewController.h中，我将添加一个按钮来调用我的respring操作。

#import <UIKit/UIKit.h>

@interface RespringViewController : UIViewController
//Creates the button
- (IBAction) respring:(id)sender;

@end

现在在RespringViewController.m内部

#import "RespringViewController.h"

@interface RespringViewController ()

@end

@implementation RespringViewController
//This calls the button created in RespringViewController.h
- (IBAction) respring: (id) sender {
setuid(0); system("killall SpringBoard");
}
//This makes the view for the button programmatically
UIButton *button9 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [button9 addTarget:self
                action:@selector(respring:)
      forControlEvents:UIControlEventTouchUpInside];
    button9.frame = CGRectMake(96.0, 262.0, 130.0, 37.0);
    button9.adjustsImageWhenDisabled = YES;
    button9.adjustsImageWhenHighlighted = YES;
    button9.alpha = 1.000;
    button9.autoresizesSubviews = YES;
    button9.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleBottomMargin;
    button9.clearsContextBeforeDrawing = YES;
    button9.clipsToBounds = NO;
    button9.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
    button9.contentMode = UIViewContentModeScaleToFill;
    button9.contentStretch = CGRectFromString(@"{{0, 0}, {1, 1}}");
    button9.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
    button9.enabled = YES;
    button9.hidden = NO;
    button9.highlighted = NO;
    button9.multipleTouchEnabled = NO;
    button9.opaque = NO;
    button9.reversesTitleShadowWhenHighlighted = NO;
    button9.selected = NO;
    button9.showsTouchWhenHighlighted = NO;
    button9.tag = 0;
    button9.titleLabel.font = [UIFont fontWithName:@"Helvetica-Bold" size:15.000];
    button9.titleLabel.lineBreakMode = UILineBreakModeMiddleTruncation;
    button9.titleLabel.shadowOffset = CGSizeMake(0.0, 0.0);
    button9.userInteractionEnabled = YES;
    [button9 setTitle:NSLocalizedString(@"APPLY SETTINGS", nil) forState:UIControlStateNormal];
    [button9 setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [button9 setTitleColor:[UIColor colorWithWhite:1.000 alpha:1.000] forState:UIControlStateHighlighted];
    [button9 setTitleShadowColor:[UIColor colorWithWhite:0.500 alpha:1.000] forState:UIControlStateNormal];

//Adds the button to the view
[view addSubview:button9];

现在，我继续构建它，并获得一个名为Respring.app的文件

例如，在Respring.app内部有以下文件

Info.plist

Icon.png

重新启动

我必须将Respring.app内部的Respring重命名为Respring_

现在我必须将下面的脚本上传到/path/to/Respring.app/

#!/bin/bash
C=/${0}
C=${C%/*}
declare -a flags
[[ :${DYLD_INSERT_LIBRARIES}: == */MobileSubstrate.dylib: ]] && flags[${#flags[@]}]=--substrate
exec "${C:-.}"/Respring_ "${flags[@]}" -- "$@" 2>>/tmp/Respring.log

并将其命名为Respring

现在，您需要使用工具ldid对二进制文件进行伪代码签名

你可以从here下载

在终端上使用以下命令

sudo ldid -S /path/to/Respring.app/Respring_

请确保对二进制文件而不是脚本进行签名

脚本必须具有正确的权限，才能以root用户身份从终端启动应用程序。您可以运行以下命令

sudo chown 0:0 /path/to/Respring.app/Respring*

sudo chmod 0755 /path/to/Respring.app/Respring

sudo chmod 4755 /path/to/Respring.app/Respring_

现在一切都设置好了，你可以启动应用程序了，任何日志都将存储在你设备的/tmp/Respring.log中，你可以使用按钮重新启动。
