[Swift]objective-cで書かれたクラスを扱う  @ App Develop , Swift , objective-c 2015年4月14日
objective-cで書かれたクラスを扱う

1.「Common-Bridging-Header.h」というヘッダーファイルを作成する
*ファイル名は任意

2.Common-Bridging-Header.hに下記を記述する
#import "EGODatabase.h"

3.PROJECT -> Build Settings -> Swift Compiler – Code Generation
-> Objective-C Bridging Headerに作成したファイル名を設定する
Objective-C Bridging Header

4.普通に扱う
let ego:EGODatabase = EGODatabase(path: "\(NSHomeDirectory())/Documents/ultrawoman.db")
private init(){
    self._initSystemTable()
}
private func createTableWithTableName(tableName:String, columnInfo:String) -> Bool{
    let query:String = "CREATE TABLE IF NOT EXISTS '\(tableName)' (\(columnInfo));"
    let result:EGODatabaseResult = self.ego.executeQuery(query)
    if 0 < result.errorCode {
        return false
    }
    return true
}
private func _initSystemTable(){
    let table:String = "id INTEGER PRIMARY KEY AUTOINCREMENT,key TEXT DEFAULT '',value TEXT DEFAULT '',modified TEXT,created TEXT"
    let result:Bool = self.createTableWithTableName(self.tableNameOfSystem, columnInfo: table)
}
[objective-c]NSTimerがFireしない  @ App Develop , objective-c 2015年3月25日
NSTimerがFireしない
UIAlertViewのYes,Noボタンをタップしたタイミングと重なったり、
何らかの要因によりNSTimerがサブスレッドで実行されることが原因

対処法
[NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(methodName) userInfo:nil repeats:NO];
これを
dispatch_async(dispatch_get_main_queue(), ^{
    [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(methodName) userInfo:nil repeats:NO];
});
こうする
