1. 用Theos新建tweak工程“iOSREGreetings” 新建iOSREGreetings工程的命令如下： snakeninnysiMac:Code snakeninny$ /opt/theos/bin/nic.pl NIC 2.0 - New Instance Creator ------------------------------ [1.] iphone/application [2.] iphone/cydget [3.] iphone/framework [4.] iphone/library [5.] iphone/notification_center_widget [6.] iphone/preference_bundle [7.] iphone/sbsettingstoggle [8.] iphone/tool [9.] iphone/tweak [10.] iphone/xpc_service Choose a Template (required): 9 Project Name (required): iOSREGreetings Package Name [com.yourcompany.iosregreetings]: com.iosre.iosregreetings Author/Maintainer Name [snakeninny]: snakeninny [iphone/tweak] MobileSubstrate Bundle filter [com.apple.springboard]: com.apple.springboard [iphone/tweak] List of applications to terminate upon installation (space-separated, '-' for none) [SpringBoard]: Instantiating iphone/tweak in iosregreetings/... Done.
%hook SpringBoard
- (void)applicationDidFinishLaunching:(id)application
{
%orig;
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Come to http://bbs.iosre.com for more fun!" message:nil delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
[alert release];
}
%end
THEOS_DEVICE_IP = iOSIP
ARCHS = armv7 arm64
TARGET = iphone:latest:8.0
include theos/makefiles/common.mk
TWEAK_NAME = iOSREGreetings
iOSREGreetings_FILES = Tweak.xm
iOSREGreetings_FRAMEWORKS = UIKit
include $(THEOS_MAKE_PATH)/tweak.mk
after-install::
install.exec "killall -9 SpringBoard"
编辑后的control内容如下：
Package: com.iosre.iosregreetings
Name: iOSREGreetings
Depends: mobilesubstrate, firmware (>= 8.0)
Version: 1.0

Description: Greetings from iOSRE!

以上代码非常简单，当SpringBoard的applicationDidFinishLaunching:函数得到调用时，代表SpringBoard的启动过程已经结束。钩住（hook）这个函数，调用%orig完成它的原始操作，然后弹出一个自定义的UIAlertView；这样一来，每次重启SpringBoard都会弹出一个对话框。你看懂了吗？
