1. 判断Cydia的URL scheme
若越狱设备没使用Cydia商店，这种判断检测不准。若设备是不完美越狱，已经回退为未越狱状态，这种判断也不准。
Swift:
func isJailBreak() -> Bool {
if let url = URL(string: "cydia://"), UIApplication.shared.canOpenURL(url) {
return true
}
return false
}
OC:
- (BOOL)isJailBreak {
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"cydia://"]]) {
return YES;
}
return NO;
}
2. 判断常见的越狱文件
可以收集常见的越狱文件，定个标准判断手机中存在一个或多个，表示手机已经越狱。
Swift:
func isJailBreak() -> Bool {
let pathArr = ["/Applications/Cydia.app", "/usr/sbin/sshd" , "/usr/sbin/sshd" , "/etc/apt"]
for path in pathArr {
if FileManager.default.fileExists(atPath: path) {
return true
}
}
return false
}
OC:
- (BOOL)isJailBreak {
NSArray *pathArr = [[NSArray alloc] initWithObjects: @"/Applications/Cydia.app", @"/usr/sbin/sshd", @"/etc/apt", nil];
for (int i = 0 ; i < pathArr.count ; i ++) {
NSString *path = pathArr[i];
if ([[NSFileManager defaultManager] fileExistsAtPath:path]) {
return YES;
}
}
return NO;
}
3. 判断能否访问系统所有应用
利用非越狱手机没权限查看Applications来判断
Swift:
func isJailBreak() -> Bool {
let appPath = "/Applications/"
if FileManager.default.fileExists(atPath: appPath) {
do {
let appList = try FileManager.default.contentsOfDirectory(atPath: appPath)
if appList.count > 0 {
return true
}
} catch let error {
print(error)
}
}
return false
}
OC:
- (BOOL)isJailBreak {
NSString *appPath = @"/Applications/";
if ([[NSFileManager defaultManager] fileExistsAtPath:appPath]) {
NSArray *appList = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:appPath error:nil];
if (appList.count > 0) {
return YES;
}
}
return NO;
}
