Ipad UISplitViewController

这篇文章是关于一个ipad里面的视图控制器的用法

首先介绍下ipad我们用storyboard构建的界面



关于界面

1.拖UISplitViewController进入storyboard

有一点需要说明的是 关于UITextView UITextView是能自适应高度的滚动视图 我们构建界面时 只需要设置其离bottom得距离 它就会自动布局好里面的文字

tableView里面cell定制中Lable也是一样的只需要设置bottom的距离

以前就讲过关于自动生成jsonmodel 还有一点关于里面的小细节

第一：如果生成的属性名称和系统的名称有冲突

处理方法：pod yymodel.h 要修改的遵从yymodel协议

具体处理看代码：

//改之前
@property (nonatomic, copy) NSString *description;
//改之后
@property (nonatomic, copy) NSString *desc;

处理方法.m文件model中

// 关联属性和JSON的key
+ (NSDictionary *)modelCustomPropertyMapper
{
return @{@"desc" : @"description"};
}
一定要在对应的模型中哦

第二：如果模型中还有数组

那我们应该对数组做处理 数组也会自动生成一个模型

在对它们做映射

//例子
@property (nonatomic, strong) NSArray *photos;

处理方法.m文件model中
// 关联属性和类
+ (NSDictionary *)modelContainerPropertyGenericClass
{
return @{@"photos" : [PhotosModel class]};
}

//sdwebimage方法请求网络数据
#import <UIImageView+WebCache.h>

[self.iconImageView sd_setImageWithURL:[NSURL URLWithString:_model.iconUrl] placeholderImage:[UIImage imageNamed:@"favicon"]];

具体过程

master 页面
#import "MasterViewController.h"
#import "AppListCell.h"
#import "AppListModel.h"

#import <YYModel.h>
#import <AFNetworking.h>
#import <MJRefresh.h>

#define IDENTIFIER @"CELL"

@interface MasterViewController ()
- (IBAction)shareAction:(UIBarButtonItem *)sender;

@property (nonatomic, strong) NSMutableArray * dataSourceArray; // 数据源数组
@property (nonatomic, assign) NSInteger currentPage; // 记录当前请求页
@property (nonatomic, strong) AFHTTPSessionManager * sessionManager; // 网络请求对象

@end

@implementation MasterViewController

- (IBAction)shareAction:(UIBarButtonItem *)sender {
// 创建ContentVC
UIImagePickerController * pickerVC = [[UIImagePickerController alloc] init];
pickerVC.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
pickerVC.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeSavedPhotosAlbum];

// 创建UIPopoverController
UIPopoverController * popoverVC = [[UIPopoverController alloc] initWithContentViewController:pickerVC];
// 显示
[popoverVC presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
// 参数1：指定位置的Rect,在什么地方显示
//    [popoverVC presentPopoverFromRect:CGRectMake(50, 50, 200, 200) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}

// 懒加载
- (NSMutableArray *)dataSourceArray
{
if (!_dataSourceArray) {
_dataSourceArray = [NSMutableArray array];
}
return _dataSourceArray;
}

// 懒加载
- (AFHTTPSessionManager *)sessionManager
{
if (!_sessionManager) {
_sessionManager = [AFHTTPSessionManager manager];
// 设置请求数据的格式
// 返回数据格式的序列化，JSON、XML、二进制数据
//        // 二进制数据序列化
//        _sessionManager.responseSerializer = [AFHTTPResponseSerializer serializer];
//        // JSON数据序列化，默认方式
//        _sessionManager.responseSerializer = [AFJSONResponseSerializer serializer];
//        // XML数据序列化
//        _sessionManager.responseSerializer = [AFXMLParserResponseSerializer serializer];
_sessionManager.responseSerializer.acceptableContentTypes = [_sessionManager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];
}
return _sessionManager;
}

- (void)viewDidLoad {
[super viewDidLoad];

// 配置UITableView
// 要实现UITableViewCell自动计算行高，满足三个条件：
// 1. iOS 8
// 2. 单元格中只有一个可变高度的视图
// 3. 设置的视图约束，必须建立和父视图的上下约束

// 设置2个步骤：
// 1. 设置行高为：UITableViewAutomaticDimension
self.tableView.rowHeight = UITableViewAutomaticDimension;
// 2. 设置估算行高为不为0的值
self.tableView.estimatedRowHeight = 100;

__weak typeof(self) weakSelf = self;
// 设置MJRefresh
// 设置下拉刷新
self.tableView.mj_header = [MJRefreshNormalHeader headerWithRefreshingBlock:^{
weakSelf.currentPage = 1;
[weakSelf requestWithPage:weakSelf.currentPage];
}];
// 设置上拉加载更多
self.tableView.mj_footer = [MJRefreshAutoNormalFooter footerWithRefreshingBlock:^{
weakSelf.currentPage++;
[weakSelf requestWithPage:weakSelf.currentPage];
}];

// 首次请求
[self.tableView.mj_header beginRefreshing];
}

// 请求数据
- (void)requestWithPage:(NSInteger)page
{
__weak typeof(self) weakSelf = self;
// 拼接请求地址
NSString * appListURL = [NSString stringWithFormat:LimitFreeURL, page];
// 通过AFHTTPSessionManager的GET方式请求数据
[self.sessionManager GET:appListURL parameters:nil success:^(NSURLSessionDataTask *task, id responseObject) {
// 请求数据成功
// 首页数据
if (page == 1) {
// 移除数据源所有数据
[weakSelf.dataSourceArray removeAllObjects];
}
// 将新请求的数据添加到数据源中
AppListModel * model = [AppListModel yy_modelWithJSON:responseObject];
[weakSelf.dataSourceArray addObjectsFromArray:model.applications];
// 刷新视图
dispatch_async(dispatch_get_main_queue(), ^{
[weakSelf.tableView reloadData];
// 停止刷新
[weakSelf.tableView.mj_header endRefreshing];
[weakSelf.tableView.mj_footer endRefreshing];
});

} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(@"error = %@", error.localizedDescription);
if (page > 1) {
weakSelf.currentPage--;
}
// 回到主线程刷新视图
dispatch_async(dispatch_get_main_queue(), ^{
