检测iphone设备是否越狱

detectDevice.h@interface UIDevice (Helper)  - (BOOL)isJailbroken;  @end

detectDevice.m@implementation UIDevice (Helper)  - (BOOL)isJailbroken {  BOOL jailbroken = NO;  NSString *cydiaPath = @"/Applications/Cydia.app";  NSString *aptPath = @"/private/var/lib/apt/";  if ([[NSFileManager defaultManager] fileExistsAtPath:cydiaPath]) {  jailbroken = YES;  }  if ([[NSFileManager defaultManager] fileExistsAtPath:aptPath]) {  jailbroken = YES;  }  return jailbroken;  }  @end

然后在你代码中调用[UIDevice currentDevice] isJailbroken], 如果返回YES说明被破解了，为NO，则没被破解。
