Is there a way to detect if the Facebook Javascript SDK loaded successfully?

阅读更多关于 Is there a way to detect if the Facebook Javascript SDK loaded successfully?

问题 I use Facebook as the membership system of my website. It uses the code to generate a login control, allowing users to login via their facebook account. It's essentially one click if they're already a member, 2 if they're not (for granting permissions). I got a problem though... feedback is suggesting the login button isn't always loading correctly.

问题 For those who helped me out earlier regarding this project, thank you very much! My code no longer has any problems, and I made extra tweaks. Now that the app is actually robust now, I want to do one more thing. See screenshot of the layout here. Normally, the toast view appears at the bottom center of the screen. I want to make it appear just below (8dp) the Submit button once OnClick is called. How can I accomplish this. See my updated complete project here. package com.lookjohn.guessnumber

Edited (2014-02-27) : I still do not fully understand all the tools. The following is my

Easy way to dismiss keyboard?

阅读更多关于 Easy way to dismiss keyboard?

问题 I have quite a few controls scattered throughout many table cells in my table, and I was wondering if there's an easier way to dismiss the keyboard without having to loop through all my controls and resigning them all as the first responder. I guess the question is.. How would I get the current first responder to the keyboard? 回答1: Try: [self.view endEditing:YES]; 回答2: You can force the currently-editing view to resign its first responder status with [view endEditing:YES] . This hides the
