AutoHome项目的学习

1.自定义UITabBar

 #import <UIKit/UIKit.h>

 @interface XHQTabBarViewController : UITabBarController
 @property(nonatomic,strong) NSMutableArray * controllers
 ;

 //@tip  创建tabbaritem
 //@para title tabbaritem标题
 //      normal 正常情况下tabbaritem图片
 //      selectedImage 选中情况下tabbaritem图片
 //      controllerName tabbaritem所对应的的控制器
 //@result  无
 -(void) addItem:(NSString*)title normalImage:(UIImage*)normal highLightImage:(UIImage*)selectedImage controller:(NSString*)controllerName ;

 #import "XHQTabBarViewController.h"

 @interface XHQTabBarViewController ()

 @end

 @implementation XHQTabBarViewController

 //初始化
 -(instancetype)init{
     if (self=[super init]) {
         _controllers = [[NSMutableArray alloc] init];
     }
     return self;
 }

 //创建tabbaritem
 -(void) addItem:(NSString*)title normalImage:(UIImage*)normal highLightImage:(UIImage*)highLight controller:(NSString*)controllerName {

     //创建tabBarItem
     normal = [normal imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
     highLight = [highLight imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
     UITabBarItem * item = [[UITabBarItem alloc] initWithTitle:title image:normal selectedImage:highLight];
     [item setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor blackColor],NSFontAttributeName: [UIFont systemFontOfSize:]} forState:UIControlStateNormal];

     //得到控制器类
     Class controllerClass = NSClassFromString(controllerName);

     //创建控制器
     UIViewController *  controller = [[controllerClass alloc] init];
     controller.navigationItem.title = title;//设置导航栏标题

     //创建导航栏
     UINavigationController * navigationController = [[UINavigationController alloc] initWithRootViewController:controller];

     //设置item
     controller.tabBarItem = item;
     //    controller.tabBarController.tabBar.barTintColor = ;
     self.tabBar.barTintColor =[UIColor colorWithRed:121.0/ green:200.0/ blue:231.0/ alpha:];

     //将控制器加入数组
     [_controllers addObject:navigationController];

 }
 @end

2.设置cell的动画:

//给cell添加动画

-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath

{

//设置Cell的动画效果为3D效果

//设置x和y的初始值为0.1；

cell.layer.transform = CATransform3DMakeScale(0.1, 0.1, 1);

//x和y的最终值为1

[UIView animateWithDuration:1 animations:^{

cell.layer.transform = CATransform3DMakeScale(1, 1, 1);

}];

}

3.表视图设置索引:

 - (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView
 {
     NSArray *array = @[@"A", @"B",@"C",@"D",@"E",@"F",@"G",@"H",@"I",@"J",@"K",@"L",@"M",@"N",@"O", @"P", @"Q", @"R", @"S", @"T", @"U", @"V", @"W", @"X", @"Y", @"Z"];
     self.tableView.sectionIndexBackgroundColor = [UIColor clearColor];//背景色
     self.tableView.sectionIndexColor = [UIColor blueColor];//字体色
     return array;
 }

 //索引点击事件
 -(NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index {

     NSLog(@"点击了第%ld个",index);
     return ;
 }

4.UICollectionView的头尾视图设置:

 #pragma mark 设置头尾视图的大小

 - (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout referenceSizeForHeaderInSection:(NSInteger)section
 {
     return CGSizeMake(XHQ_SCRWIDTH, );
 }

 #pragma mark 返回头尾视图

 - (UICollectionReusableView *)collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPath
 {
    UICollectionReusableView *reusableView = [collectionView dequeueReusableSupplementaryViewOfKind:kind withReuseIdentifier:@"HEADER" forIndexPath:indexPath];

   for(UIView *subview in reusableView.subviews)
   {
       [subview removeFromSuperview];
   }

     UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(, , XHQ_SCRWIDTH, )];

     XHQFoundCarSubModel *model = self.dataSource[indexPath.section];

     label.text = model.name;

     [reusableView addSubview:label];

     return reusableView;

 }

5.设置push动画:

//定位按钮被点击
- (void)Localself
{
    XHQFoundMoreViewController *more = [[XHQFoundMoreViewController alloc]init];

//push带动画
    [self pushNextWithType:@"suckEffect" Subtype:@"fromLeft" Viewcontroller:more];
}

 - (void)pushNextWithType:(NSString *)type Subtype:(NSString *)subtype Viewcontroller:(UIViewController *)viewController
 {
     CATransition *transition = [CATransition animation];
     transition.type = type;
     transition.subtype = subtype;
     transition.duration = ;
     viewController.hidesBottomBarWhenPushed = YES;
     [self.navigationController .view.layer addAnimation:transition forKey:nil];
     [self.navigationController pushViewController:viewController animated:nil];

 }

6.封装图形的圆角设置:

 + (void)layerCornerRadius:(CALayer *)dest radius:(float)radius width:(float)width color:(UIColor *)color
 {
     dest.cornerRadius = radius;
     dest.borderWidth = width;
     dest.borderColor = color.CGColor;
     dest.masksToBounds = YES;
 }

类方法调用:

1 [XHQAuxiliary layerCornerRadius:self.userface.layer radius: width: color:[UIColor yellowColor]];

7.实现夜间模式的开关按钮:

 if(indexPath.row == )
         {
             UISwitch *swi = [[UISwitch alloc]init];
             [swi addTarget:self action:@selector(changeValue:) forControlEvents:UIControlEventValueChanged];
             cell.accessoryView = swi;
         }

8.实现图头放大:

 #pragma mark - 实现scrollView的代理方法
 -(void)scrollViewDidScroll:(UIScrollView *)scrollView
 {
     //实现图头放大的核心思想：通过改变scrollView的偏移量来改变图片的frame
   if(scrollView == self.tableView)
   {
         //获取scrollView的偏移量
         float yOffset = scrollView.contentOffset.y;

         NSLog(@"yoffset = %f",yOffset);  //往下拉值越来越小

         //scrollView的横向偏移量是随着纵向偏移量的变化而变化
         float xOffset = (yOffset + ImageOriginHeight) / ;
         if (yOffset < -ImageOriginHeight) {
             //改变imageView的frame
             CGRect rect = _headerImageView.frame;

             rect.origin.y = -yOffset;
             rect.size.height = -yOffset * ;

             rect.origin.x = xOffset;
             rect.size.width = XHQ_SCRWIDTH + fabs(xOffset) * ;

             _headerImageView.frame = rect;
          //   NSLog(@"%f
