通过uniqueKey获取对象中的uniqueKeyVlaue时一直报错,比如BGSqlite的509和518行代码,id uniqueKeyVlaue = [self valueForKey:uniqueKey],应该改为id uniqueKeyVlaue = [object valueForKey:uniqueKey]吧,self代表BGSqlite,不是要存储的对象,怎么可能取到相应的值
@Property (nonatomic, assign) CLLocationCoordinate2D location 存此类型会直接 crash
I persisted some objects in a table called Categories and I didn't get any issue there so far but now I want to persist some objects in another table called Channels but I get this error :
this is my code :
NSArray *channelData = [channelsResults valueForKey:@"data"];
for (id details in channelData ) {
[Channels setDebug:YES];
Channels *channelsData = [Channels new];
channelsData.channelID = [details valueForKey:@"id"];
channelsData.name = [details valueForKey:@"name"];
channelsData.picture = [details valueForKey:@"picture"];
channelsData.categoryID = [details valueForKey:@"category_id"];
channelsData.desc = [details valueForKey:@"description"];
[channelData saveOrUpdate];
}
相同的模型怎么 生成不同的数据库,表名自定义
请问为什么保存不上0.239657这样的CGFloat,保留的结果只为0;
1.239657保留的结果只为1;
小数点后面的能保留吗?
这个方法不会触发update,只会insert。bg_saveOrUpdate方法调用的是BigSqlite的+(BOOL)insertOrUpdate:(id)object ignoredKeys:(NSArray* const)ignoredKeys方法,不是+(BOOL)insertOrUpdate:(id)object,在+(BOOL)insertOrUpdate:(id)object ignoredKeys:(NSArray* const)ignoredKeys方法的511、513和519行代码,没有判断uniqueKeyVlaue是否是字符串,导致查询不出来已有的数据

saveOrUpdate does not delete removed object!
i'm persisting objects from my web service into the database, for example I removed an object from the backend ,when I refresh my app it does not remove that object
for (id details in results ) {
[Categories setDebug:YES];
Categories *categoriesData = [Categories new];
categoriesData.categoryID = [details valueForKey:@"id"];
categoriesData.picture = [details valueForKey:@"picture"];
categoriesData.display_name = [details valueForKey:@"display_name"];
categoriesData.name = [details valueForKey:@"name"];
[categoriesData saveOrUpdate];
}
NSLog(@"%@",[Categories findAll]);
