推荐答案
这一切都可以轻松完成，但Apple会拒绝。
This can all be done easily, but will be rejected by Apple.
可以通过更改 com.apple.SpringBoard.plist 来更改铃声，特别是铃声密钥。
The ringtone can be changed by altering com.apple.SpringBoard.plist, specifically the ringtone key.
以下代码可用于读取自定义铃声的实际铃声标题（由iTunes同步）。
The following code can be used to read the actual ringtone title of custom ringtones (synced by iTunes).
NSMutableDictionary *custDict = [[NSMutableDictionary alloc] initWithContentsOfFile:@"/private/var/mobile/Media/iTunes_Control/iTunes/Ringtones.plist"];
NSMutableDictionary *dictionary = [custDict objectForKey:@"Ringtones"];
NSArray *keys = [dictionary allKeys];
id key = [keys objectAtIndex:indexPath.row];
NSMutableDictionary *customRingtone = [dictionary objectForKey:key];
NSString *name = [customRingtone objectForKey:@"Name"];
cell.textLabel.text = name;
可以在以下位置覆盖壁纸：
The Wallpapers can be overwritten at:
NSString *homePath1 = @"/private/var/mobile/Library/SpringBoard/HomeBackground.jpg";
NSString *homePath2 = @"/private/var/mobile/Library/SpringBoard/HomeBackgroundPortrait.jpg";
NSString *lockPath1 = @"/private/var/mobile/Library/SpringBoard/LockBackground.jpg";
NSString *lockPath2 = @"/private/var/mobile/Library/SpringBoard/LockBackgroundPortrait.jpg";
这些示例用于我的一个Cydia应用程序中。对他们来说并不多，但这些应该让你朝着正确的方向前进。
These examples were used in one of my Cydia apps. Theres not really much more to them, but these should get you going in the right direction.
