1、向Bmob里边存入图片数组
- (void)right:(UIBarButtonItem *)sender{
BmobUser *bUser = [BmobUser getCurrentUser];
if (bUser) {
//进行操作
friends = [BmobObject objectWithClassName:@"Friends"];
[friends setObject:bUser.username forKey:@"name"];
NSString *iconURLString = [[bUser objectForKey:@"imageURL"]lastObject];
[friends setObject:iconURLString forKey:@"iconImageName"];
[friends setObject:_writeNewsView.text forKey:@"newsContent"];
if (pictureData.count>1) {
NSMutableArray * dicArr = [NSMutableArray array];
int num;
for (num = 0; num < pictureData.count; num++) {
NSDictionary * dic = [[NSDictionary alloc]initWithObjectsAndKeys:@"image.jpg",@"filename",[pictureData objectAtIndex:num],@"data", nil];
[dicArr addObject:dic];
}
[BmobProFile uploadFilesWithDatas:dicArr resultBlock:^(NSArray *filenameArray, NSArray *urlArray, NSArray *bmobFileArray, NSError *error) {
if (error) {
NSLog(@"错误");
}else{
NSMutableArray * bmobFileArr = [NSMutableArray array];
for (BmobFile *file in bmobFileArray) {
[bmobFileArr addObject:file.url];
}
[friends addObjectsFromArray:bmobFileArr forKey:@"pictureArray"];
[friends saveInBackgroundWithResultBlock:^(BOOL isSuccessful, NSError *error) {
if (isSuccessful) {
[self showAlectControllerWithTitle:@"提示" Message:@"发表成功"];
[self.navigationController pushViewController:[WriteNewsViewController new] animated:YES];
}else{
[self showAlectControllerWithTitle:@"提示" Message:@"发表失败"];
}
}];
}
} progress:^(NSUInteger index, CGFloat progress) {
}];
}else{
NSLog(@"budayu1");
}
}else{
//对象为空时，可打开用户注册界面
[self showAlectControllerWithTitle:@"提示" Message:@"请登录账号"];
}
NSLog(@"%@,%lu",_writeNewsView.text,(unsigned long)pictureData.count);
}
2、读取多条数据
- (void)loadData{
BmobQuery *bquery = [BmobQuery queryWithClassName:@"Friends"];
bquery.limit = 2;
[bquery findObjectsInBackgroundWithBlock:^(NSArray *array, NSError *error) {
for (BmobObject *obj in array) {
NSLog(@"%@",[obj objectId]);
[bquery getObjectInBackgroundWithId:[obj objectId] block:^(BmobObject *object,NSError *error){
if (error){
//进行错误处理
NSLog(@"....");
}else{
if (object) {
NSLog(@"%@",[object objectForKey:@"newsContent"]);
NSLog(@"%@",[object objectForKey:@"iconImageName"]);
[list addObject:[object objectForKey:@"name"]];
[list addObject:[object objectForKey:@"newsContent"]];
[list addObject:[object objectForKey:@"iconImageName"]];
[list addObject:[object objectForKey:@"pictureArray"]];
[list addObject:[obj objectForKey:@"createdAt"]];
[dataList addObject:list];
list = [NSMutableArray array];
NSLog(@"...%@",dataList);
[self.dataArray addObjectsFromArray:[self createModelWithCount]];
}
}
[self.tableView reloadData];
}];
}
}];
}
3、复合查询读取名字和创建时间
BmobQuery *bquery = [BmobQuery queryWithClassName:@"Friends"];
[bquery whereKey:@"name" equalTo:alloc.nameLabel.text];
BmobQuery *bquery1 = [BmobQuery queryWithClassName:@"Friends"];
[bquery1 whereKey:@"createdAt" equalTo:alloc.timeLabel.text];
BmobQuery *main = [BmobQuery queryWithClassName:@"Friends"];
[main add:bquery];
[main add:bquery1];
[main orOperation];
[main findObjectsInBackgroundWithBlock:^(NSArray *array, NSError *error) {
for (BmobObject *obj in array) {
//打印playerName
NSLog(@"...%@",[obj objectForKey:@"createdAt"]);
NSLog(@"obj.playerName = %@", [obj objectForKey:@"name"]);
createTime = [obj objectForKey:@"createdAt"];
userName = [obj objectForKey:@"name"];
}
}];
4、添加多条数据
- (void)sure:(UIButton *)sender{
NSLog(@"....%@",commentTextView.text);
BmobUser *bUser = [BmobUser getCurrentUser];
if (bUser) {
//进行操作
BmobObject *comment = [BmobObject objectWithClassName:@"CommunityComment"];
[comment setObject:bUser.username forKey:@"name"];
NSString *iconURLString = [[bUser objectForKey:@"imageURL"]lastObject];
[comment setObject:iconURLString forKey:@"iconImageName"];
[comment setObject:createTime forKey:@"createTime"];
[comment setObject:userName forKey:@"userName"];
[comment setObject:commentTextView.text forKey:@"comment"];
[comment saveInBackgroundWithResultBlock:^(BOOL isSuccessful, NSError *error) {
if (isSuccessful) {
[self showAlectControllerWithTitle:@"提示" Message:@"评论成功"];
[self.navigationController pushViewController:[WriteNewsViewController new] animated:YES];
}else{
[self showAlectControllerWithTitle:@"提示" Message:@"评论失败"];
}
}];
}else{
//对象为空时，可打开用户注册界面
[self showAlectControllerWithTitle:@"提示" Message:@"请登录账号"];
}
}
