远程推送

首先 ,先导入第三方 UMessage_Sdk_1.5
在 AppDelegate.m中导入头文件 #import "UMessage.h"

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{

[UMessage startWithAppkey:@"your appkey" launchOptions:launchOptions];

//注册通知,如果要使用category的自定义策略,可以参考demo中的代码。

[UMessage registerForRemoteNotifications];

//iOS10必须,加下面这段代码。

UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];

center.delegate=self;

UNAuthorizationOptions types10=UNAuthorizationOptionBadge|  UNAuthorizationOptionAlert|UNAuthorizationOptionSound;

[center requestAuthorizationWithOptions:types10    completionHandler:^(BOOL granted, NSError * _Nullable error) {

if (granted) {

//点击允许

//这里可以添加一些自己的逻辑

} else {

//点击不允许

//这里可以添加一些自己的逻辑

}

}];

return YES;

}

//iOS10新增:处理前台收到通知的代理方法

-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{

NSDictionary * userInfo = notification.request.content.userInfo;

if([notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {

//应用处于前台时的远程推送接受

//关闭U-Push自带的弹出框

[UMessage setAutoAlert:NO];

//必须加这句代码

[UMessage didReceiveRemoteNotification:userInfo];

}else{

//应用处于前台时的本地推送接受

}

//当应用处于前台时提示设置,需要哪个可以设置哪一个

completionHandler(UNNotificationPresentationOptionSound|UNNotificationPresentationOptionBadge|UNNotificationPresentationOptionAlert);

}

//iOS10新增:处理后台点击通知的代理方法

-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{

NSDictionary * userInfo = response.notification.request.content.userInfo;

if([response.notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {

//应用处于后台时的远程推送接受

//必须加这句代码

[UMessage didReceiveRemoteNotification:userInfo];

}else{

//应用处于后台时的本地推送接受

}

}

在ViewController.m

创建 LoadData.h

#import

#import

#import "Model.h"

@interface LoadData : NSObject{

sqlite3 *ss;

}

//单例类

+(instancetype)initShaertData;

//打开数据库

-(void)initOpenData;

//添加

-(void)addData:(Model *)mm;

//查询

-(NSMutableArray *)getAllData;

//关闭

-(void)close;

在LoadData.m

#import "LoadData.h"

static LoadData *ld = nil;

@implementation LoadData

//单例类

+(instancetype)initShaertData{

static dispatch_once_t onceToken;

dispatch_once(&onceToken, ^{

ld = [[LoadData alloc]init];

});

return ld;

}

+(instancetype)allocWithZone:(struct _NSZone *)zone{

if (!ld) {

ld = [super allocWithZone:zone];

}

return ld;

}

-(id)copy{

return self;

}

-(id)mutableCopy{

return self;

}

//打开数据库

-(void)initOpenData{

NSString *path = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0];

NSString *newpath = [path stringByAppendingPathComponent:@"sy.db"];

NSLog(@"new == %@",newpath);

if (sqlite3_open([newpath UTF8String],&(ss)) == SQLITE_OK) {

NSLog(@"打开了");

[self initTable];

}

}

//初始化

-(void)initTable{

const char *sql = "create table if not exists zoo(id intager primary key, imgName text,img BLOB)";

sqlite3_stmt *stmt;

sqlite3_prepare(ss, sql, -1, &stmt, nil);

sqlite3_step(stmt);

sqlite3_finalize(stmt);

}

//添加

-(void)addData:(Model *)mm{

const char *sql = "insert into zoo values(null,?,?)";

sqlite3_stmt *stmt;

sqlite3_prepare(ss, sql, -1, &stmt, nil);

sqlite3_bind_text(stmt, 1, [mm.imgName UTF8String], -1, SQLITE_TRANSIENT);

sqlite3_bind_text(stmt, 2, [mm.img bytes],  (int)[mm.img length], SQLITE_TRANSIENT);

if (sqlite3_step(stmt) == SQLITE_DONE) {

NSLog(@"添加成功");

}

sqlite3_finalize(stmt);

}

//查询

-(NSMutableArray *)getAllData{

const char *sql = "select *from zoo";

sqlite3_stmt *stmt;

sqlite3_prepare(ss, sql, -1, &stmt, nil);

NSMutableArray *arr = [[NSMutableArray alloc]init];

while (sqlite3_step(stmt) == SQLITE_ROW) {

Model *mm = [[Model alloc]init];

mm.imgName = [NSString stringWithUTF8String:(const char *) sqlite3_column_text(stmt, 1)];

mm.img = [NSData dataWithBytes:sqlite3_column_blob(stmt, 2) length:sqlite3_column_bytes(stmt, 2)];

[arr addObject:mm];

}

sqlite3_finalize(stmt);

return arr;

}

//关闭

-(void)close{

sqlite3_close(ss);

}

创建新的 Model

在 .h中写入以下

#import

@interface Model : NSObject

@property(nonatomic,strong)NSString *imgName;

@property(nonatomic,strong)NSData *img;

@end
