HTML – Disable auto scaling on iPhone Safari when switching from portrait to landscape

Leave a comment

For iPhone users, when you are viewing a website on Safari and switch the screen orientation from portrait to landscape, you will find that the content of the page will be scaled automatically to fit the screen width. This maybe a nice feature but probably not good for responsive design.

To disable the auto scaling, you can add the following meta on your HTML inside the <head> tag.

<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0" />

 

A drawback is the above meta will disable the user scaling as well. For more information, please refer to the reference link below.

Done =)

Unlock iPhone 4s using SAM

4 Comments

Finally i have unlocked the iPhone 4s which Tinyan got it from her uncle about half a year ago. Thanks Steve for letting me know this solution. It unlocks a jailbroken iPhone 4 or iPhone 4s using SAM(Subscriber Artificial Module) which is written by Sam Bingner and it is confirmed by the MuscleNerd of iPhone Dev Team.

You can find the unlock procedures in the following 2 posts.

 

I tried a few times by following the above steps but no luck. Whenever i connect the iPhone 4s to iTunes in the final step, iTunes always returned that the phone cannot be activated.

Finally, i follow the screencast made by Jeff Benjamin from iDownloadBlog and suddenly the signal bar appears.

You can even upload the picture to the internet and share it in social networks. Continue reading Score Marker – My Second Approved iPhone App →

iPhone – Add the Return Key for UIKeyboardTypeNumberPad

But that only works in iOS SDK <= 3.2M. After i upgrade it to 4.0, that feature was broken.

It is found that the we have add the observer to the UIKeyboardDidShowNotification instead of UIKeyboardWillShowNotification. Moreover, the view prefix is changed from <UIKeyboard to <UIPeripheralHostView. Here comes the code. Continue reading iPhone – Add the Return Key for UIKeyboardTypeNumberPad in iPhone SDK 4 →

iPhone – Create an URL Link

Leave a comment

We can add an open URL action in iPhone application by the following line of code.

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://ykyuen.wordpress.com"]];

please note that it will close the application and open the URL in browser.

And if you want to have a direct link to Apple appstore, you can get the URL from iTunes Link Maker.
