目标c中的断言失败错误

我有Json数据，但是当我尝试将这些logging插入到sqlite数据库时，我得到了这个错误断言失败。 我可以看到与NSLog的数据，但我不能插入数据库。 哪里不对？ 我该如何解决？ 感谢您的回复。 我的代码如下：

-(void)processDoneWithRequestName:(NSString*)tagName{ sqlite3_stmt *stmt=nil; //NSArray *pathsArray=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES); NSString *doumentDirectoryPath=@"/Users/ds/Desktop/SqliteTest/SqliteTest"; NSString *cruddatabase=[doumentDirectoryPath stringByAppendingPathComponent:@"SqliteTestDb.sqlite"]; if ([tagName isEqualToString:Logins]) { int keys = [[response.item objectForKey:@"Lipton"] count]; NSLog(@"count %i",keys); for (int i=0; i<keys; i++) { NSString *str1 =[[[response.item objectForKey:@"Lipton"] objectAtIndex:i]objectForKey:@"IsSuccess"]; NSString *str2 =[[[response.item objectForKey:@"Lipton"] objectAtIndex:i]objectForKey:@"ProducerId"]; NSString *str3 =[[[response.item objectForKey:@"Lipton"] objectAtIndex:i]objectForKey:@"Latitude"]; NSString *str4 =[[[response.item objectForKey:@"Lipton"] objectAtIndex:i]objectForKey:@"Longitude"]; NSString *str5 =[[[response.item objectForKey:@"Lipton"] objectAtIndex:i]objectForKey:@"Altitude"]; NSString *str6 =[[[response.item objectForKey:@"Lipton"] objectAtIndex:i]objectForKey:@"Slope"]; NSString *str7 =[[[response.item objectForKey:@"Lipton"] objectAtIndex:i]objectForKey:@"SampleDate"]; NSString *str8 =[[[response.item objectForKey:@"Lipton"] objectAtIndex:i]objectForKey:@"PackageNo"]; NSString *str9 =[[[response.item objectForKey:@"Lipton"] objectAtIndex:i]objectForKey:@"Status"]; NSString *str10 =[[[response.item objectForKey:@"Lipton"] objectAtIndex:i]objectForKey:@"Description"]; if (sqlite3_open([cruddatabase UTF8String], &cruddb)==SQLITE_OK) { const char *sql = "INSERT INTO LabUpdate (IsSuccess, ProducerId, Latitude, Longitude, Altitude, Slope, SampleDate, PackageNo, Status, Description) VALUES (?,?,?,?,?,?,?,?,?,?)"; NSInteger result = sqlite3_prepare_v2(cruddb,sql, -1, &stmt, NULL); if(sqlite3_step(stmt) == SQLITE_ROW || result == SQLITE_ROW) { sqlite3_prepare_v2(cruddb, sql, 1, &stmt, NULL); sqlite3_bind_int(stmt, 1, [str1 integerValue]); sqlite3_bind_int(stmt, 2, [str2 integerValue]); sqlite3_bind_double(stmt, 3, [str3 floatValue]); sqlite3_bind_double(stmt, 4, [str4 floatValue]); sqlite3_bind_double(stmt, 5, [str5 floatValue]); sqlite3_bind_double(stmt, 6, [str6 floatValue]); sqlite3_bind_text(stmt, 7, [str7 UTF8String], -1, SQLITE_TRANSIENT); sqlite3_bind_int(stmt, 8, [str8 integerValue]); sqlite3_bind_int(stmt, 9, [str9 integerValue]); sqlite3_bind_text(stmt, 10, [str10 UTF8String], -1, SQLITE_TRANSIENT); } else { NSAssert1(0, @"Error . '%s'", sqlite3_errmsg(cruddb)); } sqlite3_reset(stmt); sqlite3_finalize(stmt); } } sqlite3_close(cruddb); } } 

Answer 1

我不认为你的path是正确的，它不应该被硬编码，应该开始与文件：/ /。

使用它来获取文档目录并保存在那里

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

Answer 2

看看下面的代码

 if (sqlite3_open([cruddatabase UTF8String], &cruddb)==SQLITE_OK) { sqlite3_prepare_v2(cruddatabase, "BEGIN TRANSACTION", -1, &compiledStmt, NULL); sqlite3_step(compiledStmt); sqlite3_finalize(compiledStmt); const char *sql = "INSERT INTO LabUpdate (IsSuccess, ProducerId, Latitude, Longitude, Altitude, Slope, SampleDate, PackageNo, Status, Description) VALUES (?,?,?,?,?,?,?,?,?,?)"; if(sqlite3_prepare_v2(cruddatabase, sql, -1, &stmt, NULL) == SQLITE_OK){ sqlite3_prepare_v2(cruddb, sql, 1, &stmt, NULL); sqlite3_bind_int(stmt, 1, [str1 integerValue]); sqlite3_bind_int(stmt, 2, [str2 integerValue]); sqlite3_bind_double(stmt, 3, [str3 floatValue]); sqlite3_bind_double(stmt, 4, [str4 floatValue]); sqlite3_bind_double(stmt, 5, [str5 floatValue]); sqlite3_bind_double(stmt, 6, [str6 floatValue]); sqlite3_bind_text(stmt, 7, [str7 UTF8String], -1, SQLITE_TRANSIENT); sqlite3_bind_int(stmt, 8, [str8 integerValue]); sqlite3_bind_int(stmt, 9, [str9 integerValue]); sqlite3_bind_text(stmt, 10, [str10 UTF8String], -1, SQLITE_TRANSIENT); NSUInteger err = sqlite3_step(compiledStmt); if (err != SQLITE_DONE){ NSLog(@"error while binding %d %s",err, sqlite3_errmsg(database)); } sqlite3_reset(compiledStmt); sqlite3_finalize(compiledStmt); } else { NSLog(@"Invalid Query"); } sqlite3_prepare_v2(cruddatabase, "END TRANSACTION", -1, &compiledStmt, NULL); sqlite3_step(compiledStmt); sqlite3_finalize(compiledStmt); sqlite3_close(cruddatabase);
