我尝试使用 theos 编译一个调整，这是一个令人惊叹的框架，可以在许多不同的平台上轻松创建调整。在这里，我每次重新启动并慢慢淡出它时都尝试显示一个设置图标，但它无法编译。我有所有需要的头文件和框架，并且正在运行一个真正的 Mac（尽管你在我的终端上看到了这个名字：P），安装了最新的 Xcode 和以前安装的 Xcode 4.2。这是tweak.xm：

#import <UIKit/UIKit2.h>
#import <objc/runtime.h>
#import <SpringBoard/SpringBoard.h>
#import <Foundation/Foundation.h>
#import <AudioToolbox/AudioToolbox.h>
#import <substrate2.h>
#import <IOSurface/IOSurface.h>
#import <QuartzCore/QuartzCore2.h>
#import <CoreGraphics/CoreGraphics.h>
#import <CaptainHook/CaptainHook.h>
#import <Foundation/Foundation.h>
#import <objc/runtime.h>
#import <AVFoundation/AVAudioPlayer.h>
#import <Celestial/Celestial.h>
#import <SpringBoardServices/SpringBoardServices.h>
#import <CoreFoundation/CFNotificationCenter.h>
#import <ChatKit/ChatKit.h>

%hook CKConversationListController

- (void)composeButtonClicked:(id)clicked {
}
%end

%hook SpringBoard
-(void)applicationDidFinishLaunching:(id)application {
NSArray *animationArray = [NSArray arrayWithObjects:[UIImage imageNamed:@"/Applications/Preferences.app/BlobIcon@2x.png"], nil];


         [NSTimer scheduledTimerWithTimeInterval:.75 target:self selector:@selector(crossfade) userInfo:nil repeats:YES];

    mainImageView.animationImages = animationArray;


    mainImageView.animationDuration = 4.5; //mainImageView is instance of UIImageView

    mainImageView.animationRepeatCount = 0;

    [mainImageView startAnimating];


    CABasicAnimation *crossFade = [CABasicAnimation animationWithKeyPath:@"contents"];
    crossFade.autoreverses = YES;
    crossFade.repeatCount = 1;
    crossFade.duration = 1.0;
}

%new
- (void) crossfade {
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; // user dependent transition acn be set here
    mainImageView.alpha = !mainImageView.alpha;
    [UIView commitAnimations];
}
%end

makefile 看起来像这样：

include theos/makefiles/common.mk
export GO_EASY_ON_ME=1

TWEAK_NAME = Goofy
Goofy_FILES = Tweak.xm
Goofy_FRAMEWORKS = Foundation UIKit CoreGraphics ChatKit
Goofy_PRIVATE_FRAMEWORKS = ChatKit VoiceServices AppSupport

include $(THEOS_MAKE_PATH)/tweak.mk

我不断得到

 Preprocessing Tweak.xm...

我在这里想念什么？

问题是 mainImageView 没有被声明为任何东西......

做就是了UIImageView *mainImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"/Applications/Preferences.app/BlobIcon@2x.png"]];

除非你试图移动一个已经在锁屏上的对象，比如时钟，在这种情况下，你需要找出这个对象是什么，将它包含在文件中#import，然后像你已经拥有的那样对其进行动画处理。
