我使用以下代码使用iphone插入sqllite - (无效)保存{
AlarmData *alarm=[CallSettings getAlarm];
alarm.subject=subjectText.text;
alarm.sound=tempDefault;
NSDate *dat=[datePicker date];
NSString *da=(NSString *)[NSString stringWithFormat:@"%@",dat];
alarm.date=da;
//alarmData.date=da;
NSLog([CallSettings getAlarm].subject);
NSLog([CallSettings getAlarm].no1);
NSLog([CallSettings getAlarm].lname);
NSLog([CallSettings getAlarm].name);
NSLog([CallSettings getAlarm].date);
NSLog([CallSettings getAlarm].sound);
NSString *fullName=[NSString stringWithFormat:@"%@ %@",alarm.name,alarm.lname];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0];
NSString *filePath = [documentsPath stringByAppendingPathComponent:@"appointment.sql"];
sqlite3 *database;
if(sqlite3_open([filePath UTF8String], &database) == SQLITE_OK) {
// Setup the SQL Statement and compile it for faster access
const char *sqlStatement = "select * from Alarm";
sqlite3_stmt *compiledStatement;
if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) {
// Loop through the results and add them to the feeds array
compiledStatement=NULL;
const char *sql = "insert into Alarm(name) values ('Ahmed')";
if(sqlite3_prepare_v2(database, sql, -1, &compiledStatement, NULL) != SQLITE_OK);
else {
if(SQLITE_DONE != sqlite3_step(compiledStatement))
NSAssert1(0, @"Error while inserting data. '%s'", sqlite3_errmsg(database));
else
//SQLite provides a method to get the last primary key inserted by using sqlite3_last_insert_rowid
//coffeeID = sqlite3_last_insert_rowid(database);
NSLog(@"Value is inserted");
// sqlite3_reset(compiledStatement);
}
}
}
}
sqlite3_close(database);
} //保存方法结束
调用此方法时,应用程序崩溃并发生以下错误

和应用程序下次不运行,除非我从我的设备中删除应用程序,我认为数据库文件崩溃

你应该使用sqlite3_finalize(compiledStatement)而不是compiledStatement = NULL; 只需阅读文档,您就会明白原因。或者你可以使用另一个变量sqlite3_stmt,用于INSERT。
