iCloud 与 iAd---iOS

iCloud云存储

1. 在苹果开发者中心 AppID中勾选iCloud，重新生成描述文件profile
2. 在项目中|Capabilities 中打开iCloud，勾选 Key-Value ， iCloud Documents。 会自动生成项目.entitlements文件
3. 手机中设置iCloud账号

存储文档

1. 自定义UIDocument对象类

#import 

@interface YTSDocument : UIDocument

@property (nonatomic,strong) NSData *data;
@end

#import "YTSDocument.h"

@implementation YTSDocument


// 存储时调用
-(id)contentsForType:(NSString *)typeName error:(NSError * _Nullable __autoreleasing *)outError{

    if(_data){
    
        return [_data copy];
    }
    return [NSData data];
}

// 读取时调用
-(BOOL)loadFromContents:(id)contents ofType:(NSString *)typeName error:(NSError * _Nullable __autoreleasing *)outError{

    _data=[contents copy];
    return true;
}

@end

2. VC

#import "YTViewController.h"
#import "YTSDocument.h"

@interface YTViewController ()
@property (nonatomic,strong) NSMetadataQuery *dataQuery;
@property (nonatomic,strong) NSMutableDictionary *fileDic;  // @{文件名:修改时间}
@property (nonatomic,strong) YTSDocument *dcocument;
@end


@implementation YTPersonCCViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    
    // 查询icloud文档列表对象
    _dataQuery=[NSMetadataQuery new];
    _dataQuery.searchScopes=@[NSMetadataQueryUbiquitousDataScope];
    // noti
    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(queryFinish:) name:NSMetadataQueryDidFinishGatheringNotification object:_dataQuery];
    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(queryFinish:) name:NSMetadataQueryDidUpdateNotification object:_dataQuery];
    // 开始查询
    [_dataQuery startQuery];
}

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{

    
    
}

// noti
-(void)queryFinish:(NSNotification *)noti{

    // 获取查询列表，遍历
    NSArray *dataArr=_dataQuery.results;
    _fileDic=[NSMutableDictionary dictionary];
    [dataArr enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        NSMetadataItem *item=obj;
        
        // 文件名,最后修改时间
        NSString *fileName=[item valueForAttribute:NSMetadataItemFSNameKey];
        NSDate *date=[item valueForAttribute:NSMetadataItemFSContentChangeDateKey];
        NSDateFormatter *dateFormat=[NSDateFormatter new];
        [dateFormat setDateFormat:@"yy-MM-dd hh:mm"];
        NSString *dateString=[dateFormat stringFromDate:date];
        [_fileDic setObject:dateString forKey:fileName];
    }];
}

// 获取icloud文件地址
-(NSURL *)getICloudURL:(NSString *)fileName{
    return [[[[NSFileManager defaultManager]URLForUbiquityContainerIdentifier:@"entitie文件中ID"]URLByAppendingPathComponent:@"Documents"]URLByAppendingPathComponent:fileName];
}
// 新建文档
-(void)addDocument:(NSString *)fileName{

    //
    NSURL *fileURL=[self getICloudURL:fileName];
    // 新建文档对象
    YTSDocument *document=[[YTSDocument alloc]initWithFileURL:fileURL];
    [document saveToURL:fileURL forSaveOperation:UIDocumentSaveForCreating completionHandler:^(BOOL success) {
        //
        if(success){
        
            // 开始查询
            [_dataQuery startQuery];
            // reloadData
            
            
            //
            _dcocument=document;    //
        }else{
        
            //
            NSLog(@"save fail");
        }
    }];

}

//
-(void)removeDocument:(NSString *)fileName{
    
    //
    NSError *error;
    [[NSFileManager defaultManager]removeItemAtURL:[self getICloudURL:fileName] error:&error];
    if(error){
        //
        NSLog(@"error:%@",error.localizedDescription);
    }
    [_fileDic removeObjectForKey:fileName];
    
    // reloadData
}

-(void)querryDocument:(NSString *)fileName{
    // 获取文档
    NSURL *fileURL=[self getICloudURL:fileName];
    YTSDocument *document=[[YTSDocument alloc]initWithFileURL:fileURL];
    
    // 打开文档
    [document openWithCompletionHandler:^(BOOL success) {
        if(success){
        
            //
            NSString *dataText=[[NSString alloc]initWithData:document.data encoding:NSUTF8StringEncoding];
        }else{
            NSLog(@"read fail");
        }
    }];
    
    // 保存文档
    [document saveToURL:document.fileURL forSaveOperation:UIDocumentSaveForOverwriting completionHandler:^(BOOL success) {
        NSLog(@"save success");
    }];
}
@end

存储键值对

    // 用法同NSUserDefaults
    NSUbiquitousKeyValueStore *defaults=[NSUbiquitousKeyValueStore defaultStore];
    [defaults setBool:true forKey:@""];
    [defaults synchronize];
    
    
    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(valueChange:) name:NSUbiquitousKeyValueStoreDidChangeExternallyNotification object:defaults];

iAd内置广告

#import "YTViewController.h"
#import 

@interface YTViewController ()

@property (nonatomic,strong) ADBannerView *adView;
@end


@implementation YTPersonCCViewController

- (void)viewDidLoad {
    [super viewDidLoad];


    //
    _adView=[ADBannerView new];
    _adView.delegate=self;
    [_adView setFrame:self.view.frame];
    [self.view addSubview:_adView];
}

#pragma mark dele
// 广告加载完后调用
-(void)bannerViewDidLoadAd:(ADBannerView *)banner{
    NSLog(@"loaded ad");
}
// 点击广告后调用（false则不弹全屏）
-(BOOL)bannerViewActionShouldBegin:(ADBannerView *)banner willLeaveApplication:(BOOL)willLeave{
    return YES;
}
// 关闭广告后调用
-(void)bannerViewActionDidFinish:(ADBannerView *)banner{
    NSLog(@"广告已关闭");
}
// 获取广告失败后调用
-(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error{
    NSLog(@"广告加载失败:%@",error);
    _adView.hidden=true;
}

@end
