“Apple Mach-O (id) linker” error when adding external libraries to project

由 眉间皱痕 提交于 2019-12-10 17:29:59
问题 I added FMDB to my project then added the frameworks libsqlite3.dylib and libsqlite3.0.dylib, but I still get the build error. If I remove the FMDB classes from my project then it builds just fine. What other things should I check? Detailed info on the error: Ld /Users/gmi/Library/Developer/Xcode/DerivedData/iNROMockUp5->gjmgpakyszrgwbbxnkdxehexacxm/Build/Products/Debug->iphonesimulator/iNROMockUp5.app/iNROMockUp5 normal i386 cd /iOSDev/Testing/iNROMockUp5 setenv MACOSX_DEPLOYMENT_TARGET 10.6

FMDB not inserting into DB

由 余生长醉 提交于 2019-12-10 12:07:55
问题 I am trying to use FMDB to insert a few queries into the DB. When I check the query for insert it is saying that it is inserting. Later I can actually read the data from the Tables. But what happens is that if I try to read the information from the DB, it comes back as null. When I checked the DB in the Xcode Project, not seems to have updated. It kind of confusing me. Any suggestion what the problem could be? 回答1: Your code is wrong. This is what I use to write: NSArray *paths =

iOS sqlite/FMDB update not working

由 纵然是瞬间 提交于 2019-12-08 11:35:18
问题 This isn't as easy and specific to ask as I'd like, but I'm really stuck with something. I followed this tutorial, recreating it very similar for an iPad app: http://www.highoncoding.com/Articles/836_Persisting_iOS_Application_Data_in_SQLite_Database_Using_FMDB.aspx The issue I'm running into is the edit customer and save portion. I've thrown in NSLog's with the customers new name that I edit, and it gets pushed through all the functions, so I'm thinking it's breaking in the update command.

问题 My apps UI stucks because of semaphore_wait_trap . I don't know how to track it. I've checked if I am updating any UI from background thread. But did not find any. Here is the stack trace.

How do I make FMDB's database a singleton

由 做~自己de王妃 提交于 2019-12-07 08:38:48
问题 I have been using SQLite for awhile now, and have decided to go to FMDB. I need to make it a singleton. Here's my code below; what do I have to change to have FMDB access the singleton d/b? #pragma mark Singleton Methods + (SQLiteDB *) sharedSQLiteDB { if(!sharedSQLiteDB) { sharedSQLiteDB = [[SQLiteDB alloc] init]; [sharedSQLiteDB openCreateDB]; // check to see if d/b exists } return sharedSQLiteDB; } and this is the code I use to initialize the d/b using FMDB: //-----------------------

memory leak (?) after sqlite+fmdb vacuum command

由 给你一囗甜甜゛ 提交于 2019-12-06 04:17:07
I'm using sqlite in my app via the FMDB wrapper. Memory usage in my app sits at 2.25 MB before a call to VACUUM: [myFmdb executeUpdate: @"VACUUM;" ]; Afterwords its at 5.8 MB, and I can't seem to reclaim the memory. Post-vacuum, the Instruments/Allocations tool shows tons of sqlite3MemMalloc calls with live bytes, each allocating 1.5 K. Short of closing the database and reopening it (an option), how can I clean this up? Edit : closing and reopening the database connection does clear up the memory. This is my solution unless someone can shed some further insight to this. I posted this question

how do we open an already existing database fmdb and where to include it?

由 纵饮孤独 提交于 2019-12-06 04:07:55
问题 I am using fmdb but i am not knowing where to add the db file. I found this old answer that i think it doesn't fit for xcode 4.2 (since we dont have 'Resources' folder anymore). I created a database in 'Lita', added the extension .sqlite and added the db file as follows : then tried to use the following NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *docsPath = [paths objectAtIndex:0]; NSString *path = [docsPath
