《无限互联IOS开发之手势密码的实现.docVIP

手势密码解析 代码结构: GesturePasswordView ?用以?首?页布局 GesturePasswordButton ?用以设置按钮效果 GesturePasswordController ?用以实现各个功能模块 KeychainItemWrapper ?用以保存密码信息 TentacleView ?用以设置输?入密码时的线条效果并接受?手势事件 代码分析: 密码?首?页布局:GesturePasswordView通过循环九个button排列出?手势密码区,所有的button都存?入buttonArray数组当中,并添加了?一个 state Label类 ?用以显?示提?示信息 [objc]?view plaincopy -?(id)initWithFrame:(CGRect)frame?? {?? self?=?[super?initWithFrame:frame];?? //?首?页密码视图布局if?(self)?{?? //?Initialization?code?? buttonArray?=?[[NSMutableArray?alloc]initWithCapacity:0];?? view?=?[[UIView?alloc]initWithFrame:CGRectMake(frame.size.width/2-160,?frame.size.height/2-80,?320,?320)];?? //创建密码键盘?小视图?0-9for?(int?i=0;?i9;?i++)?{??
