[Objective-C] 剛轉入寫iOS Objective的一些簡單筆記~

記錄一下菜到不行的初學者(我本人XD)Objective-C 寫的筆記

變數宣告strong跟weak

用segue轉到另一個view如何退上去的方法

[self dismissViewControllerAnimated:true completion:nil];

用Navigation控制轉viewController

By using below line we can go to parent view controller

[self.navigationController popViewControllerAnimated:YES];


By using below line we can move to main/root view controller

[self.navigationController popToRootViewControllerAnimated:YES];


By using below line we can move to any view controller

[self.navigationController popToViewController:viewControllerObject animated:YES];

UIthread不同步的處理方法

dispatch_async(dispatch_get_main_queue(), ^{

[self.accessTokenText setText:userAccessToken];

[self.refreshTokenText setText:userRefreshToken];

});

                                                          

UIAlertView iOS9 停用後請改用UIAlertController

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Title" message:@"Message" preferredStyle:UIAlertControllerStyleAlert]; UIAlertAction* ok = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:nil]; [alertController addAction:ok]; [self presentViewController:alertController animated:YES completion:nil];
