开发随笔

1 关于TextFiled 输入类容改变代理

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
    //text 最准确的字符串
    NSString *text = [textField.text stringByReplacingCharactersInRange:range withString:string];
    NSLog(@"---text:%@",text);//输入改变后最及时的text（眼睛能够看到的）
    NSLog(@"---textField:%@",textField.text); //入股改变前的文本
    NSLog(@"---string:%@",string); //当前操作的单个字符
    return YES;
}

过渡动画

    //添加展示动画
    CATransition *anima = [CATransition animation];
    anima.type = kCATransitionMoveIn;//设置动画的类型
    anima.subtype = kCATransitionFromRight; //设置动画的方向
    anima.duration = 0.5f;
    [_searchV.layer addAnimation:anima forKey:@"moveInAnimation"];

手势冲突

#pragma mark tapGestureRecgnizerdelegate 解决手势冲突
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
    if ([touch.view isKindOfClass:[UITableView class]]){
        return NO;
    }
    if ([NSStringFromClass([touch.view class]) isEqualToString:@"UITableViewCellContentView"]) {
        return NO;
    }
    return YES;
}

改变状态栏颜色

先将View controller-based status bar appearance设为YES，然后在该控制器内添加

//NavControllerView  重写
- (UIViewController *)childViewControllerForStatusBarStyle {
    return self.topViewController;
}

//单个子页面改变
-(UIStatusBarStyle)preferredStatusBarStyle
{
    return UIStatusBarStyleLightContent;
}
