這篇文章主要為大家詳細(xì)介紹了iOS購(gòu)物分類模塊的實(shí)現(xiàn)方案，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下
本文實(shí)例分享了iOS購(gòu)物分類模塊的實(shí)現(xiàn)方案，供大家參考，具體內(nèi)容如下
啟動(dòng)
在AppDelegate中創(chuàng)建主視圖控制器。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
Basetabarcontroller*base=[[Basetabarcontroller alloc]init];
self.window.rootViewController=base;
return YES;
}
UI框架設(shè)計(jì)
Basetabbarcontroller基于UITabBarController，作為主視圖控制器。
頭文件如下：
@interface Basetabarcontroller : UITabBarController
@end
實(shí)現(xiàn)文件中主要做了2點(diǎn)：創(chuàng)建視圖控制器ClassViewController，并將它設(shè)置到新創(chuàng)建的創(chuàng)建導(dǎo)航控制器中。
- (void)viewDidLoad {
[super viewDidLoad];
self.tabBar.tintColor = [UIColor redColor];
// self.tabBar.barTintColor = [UIColor blackColor];
ClassViewController*classList=[[ClassViewController alloc]init];
//classList.title=@"分類";
[self addChildViewController:classList title:@"分類" image:@""];
UIButton *menuBtn = [UIButton buttonWithType:UIButtonTypeCustom];
menuBtn.frame = CGRectMake(0, 0, 20, 18);
[menuBtn setBackgroundImage:[UIImage imageNamed:@"1.png"] forState:UIControlStateNormal];
[menuBtn addTarget:self action:@selector(openOrCloseLeftList) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:menuBtn];
//self.tabBar.barTintColor = [UIColor redColor];
}
- (void)addChildViewController:(UIViewController *)childController title:(NSString *)title image:(NSString *)image{
UINavigationController *childVC = [[UINavigationController alloc]initWithRootViewController:childController];
childVC.tabBarItem.title = title;
childVC.tabBarItem.image = [UIImage imageNamed:image];
childVC.navigationBar.barTintColor = [UIColor whiteColor];
[self addChildViewController:childVC];
}
主要的界面視圖控制器定義：
@interface ClassViewController : UIViewController @end
實(shí)現(xiàn)文件中：
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
UIBarButtonItem *searchBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSearch target:self action:@selector(searchBarButtonItemAction)];
self.navigationItem.rightBarButtonItem = searchBarButtonItem;
[self setdata];
[self setimage];
[self setdeatil];
_a=1;
_b=1;
_segement=[[UISegmentedControl alloc]initWithItems:@[@"攻略",@"詳情"]];
_segement.frame=CGRectMake(90, 20, kwidth-180, 30);
_segement.tintColor=[UIColor blackColor];
_segement.selectedSegmentIndex=0;
[_segement addTarget:self action:@selector(changevalue:) forControlEvents:(UIControlEventValueChanged)];
self.navigationItem.titleView =_segement;
self.scrollview=[[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, kwidth, KHeight)];
_scrollview.directionalLockEnabled=YES;
_scrollview.contentSize=CGSizeMake(kwidth*2, KHeight);
_scrollview.delegate=self;
[self.view addSubview:self.scrollview];
UICollectionViewFlowLayout*flow=[[UICollectionViewFlowLayout alloc]init];
//列距
flow.minimumInteritemSpacing=20;
//行距
flow.minimumLineSpacing=40;
//分區(qū)內(nèi)邊距
flow.sectionInset=UIEdgeInsetsMake(0, 20, 20, 20);
CGFloat totalwidth=self.view.frame.size.width;
CGFloat itemwidth=(totalwidth-2*20-3*20)/4.0;
CGFloat itemheight=itemwidth;
flow.itemSize=CGSizeMake(itemwidth, itemheight);
flow.headerReferenceSize=CGSizeMake(0, 40);
//滾動(dòng)方向
flow.scrollDirection= UICollectionViewScrollDirectionVertical;
;
//區(qū)頭大小
flow.headerReferenceSize=CGSizeMake(0, 100);
_collection=[[UICollectionView alloc]initWithFrame:[UIScreen mainScreen].bounds collectionViewLayout:flow];
_collection.backgroundColor=[UIColor whiteColor];
_collection.tag=1;
_Srr=@[@"1",@"s",@"2",@"r"];
for (NSString*St in _Srr) {
[_collection registerClass:[UICollectionReusableView class] forSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:St];}
//設(shè)置 數(shù)據(jù)源 和代理
_collection.dataSource=self;
_collection.delegate=self;
[_collection registerClass:[ClassCollectionViewCell class] forCellWithReuseIdentifier:@"mycell"];
// _collection.backgroundColor=[UIColor yellowColor];
_collection.directionalLockEnabled=YES;
[self.scrollview addSubview:_collection];
UIView*view=[[UIView alloc]initWithFrame:CGRectMake(kwidth, 0, kwidth, 30)];
// view.backgroundColor = [UIColor whiteColor];
UIButton*label=[UIButton buttonWithType:(UIButtonTypeSystem)];
label.frame=CGRectMake(0, 20, 200, 14) ;
[label setTitle:@"選禮神器" forState:(UIControlStateNormal)];
[label addTarget:self action:@selector(xuan) forControlEvents:(UIControlEventTouchUpInside)];
[view addSubview:label];
[self.scrollview addSubview:view];
網(wǎng)絡(luò)數(shù)據(jù)封裝
基于NFNetworking，封裝了3個(gè)接口
@interface LORequestManger : NSObject
+ (void)POST:(NSString *)URL params:(NSDictionary * )params success:(void (^)(id response))success
failure:(void (^)(AFHTTPRequestOperation *operation,NSError *error))Error;
+ (void)GET:(NSString *)URL
success:(void (^)(id response))success
failure:(void (^)(AFHTTPRequestOperation *operation,NSError *error))Error;
+ (void)UPLOADIMAGE:(NSString *)URL
params:(NSDictionary *)params
uploadImage:(UIImage *)image
success:(void (^)(id response))success
failure:(void (^)(AFHTTPRequestOperation *operation,NSError *error))Error;
@end
實(shí)現(xiàn)文件：
#import "LORequestManger.h"
#define serverUrl @"http://192.168.1.1:8080/jiekou"
@implementation LORequestManger
+ (void)POST:(NSString *)URL params:(NSDictionary * )params success:(void (^)(id response))success
failure:(void (^)(AFHTTPRequestOperation *operation,NSError *error))Error
{
// 創(chuàng)建請(qǐng)求管理者
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
// 請(qǐng)求超時(shí)時(shí)間
manager.requestSerializer.timeoutInterval = 30;
NSString *postStr = URL;
if (![URL hasPrefix:@"http"]) {
postStr = [NSString stringWithFormat:@"%@%@", serverUrl,URL] ;
}
NSMutableDictionary *dict = [params mutableCopy];
// 發(fā)送post請(qǐng)求
[manager POST:postStr parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject) {
// 請(qǐng)求成功
NSDictionary *responseDict = (NSDictionary *)responseObject;
success(responseDict);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {// 請(qǐng)求失敗
Error( operation,error);
}];
}
+ (void)GET:(NSString *)URL
success:(void (^)(id response))success
failure:(void (^)(AFHTTPRequestOperation *operation,NSError *error))Error
{
// 獲得請(qǐng)求管理者
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] init];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setHTTPShouldHandleCookies:NO];
manager.requestSerializer.timeoutInterval = 30;
NSString *getStr = URL;
// NSLog(@"getStr======%@",getStr);
if (![URL hasPrefix:@"http"]) {
getStr = [NSString stringWithFormat:@"%@%@", serverUrl,URL] ;
}
// 發(fā)送GET請(qǐng)求
[manager GET:getStr parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
// NSLog(@"getStr------------%@",getStr);
NSDictionary *responseDict = (NSDictionary *)responseObject;
success(responseDict);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
if (!operation.responseObject) {
NSLog(@"網(wǎng)絡(luò)錯(cuò)誤");
}
Error( operation,error);
}];
}
+ (void)UPLOADIMAGE:(NSString *)URL
params:(NSDictionary *)params
uploadImage:(UIImage *)image
success:(void (^)(id response))success
failure:(void (^)(AFHTTPRequestOperation *operation,NSError *error))Error
{
// 創(chuàng)建請(qǐng)求管理者
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer.timeoutInterval = 30;
// [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
//
// [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];
NSString *postStr = [NSString stringWithFormat:@"%@%@", serverUrl,URL] ;
NSMutableDictionary *dict = [params mutableCopy];
[manager POST:postStr parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
NSData *imageData = UIImageJPEGRepresentation(image, 0.1);
[formData appendPartWithFileData:imageData name:@"img" fileName:@"head.jpg" mimeType:@"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSDictionary *responseDict = (NSDictionary *)responseObject;
success(responseDict);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
Error( operation,error);
}];
}
