Not only browsers portatitli desktop or browsing the sites developed by us, now the era of mobile - the mobile browser - is widespread, thanks to devices like the Apple iPhone, Android, etc ... Furthermore, even for developers for the Apple iPhone has become mandatory to understand to which device the application is running.
On the Web, the situation is similar to that displayed in the Browser or Mobile Browser? , with the variant:
In this last period I worked on three applications for Apple iPhone, virtually simultaneously. Two have already been approved by Apple and are located on the App Store: thefirst and iMakeLove .
In both applications have adopted the use of an object UIWebView to display the instructions.
The object UIWebView ilevato was really comfortable in this case. It allowed me to quickly view and a nice text, images, and accompanied, if anything else is displayed on a Web page (Flash on iPhone not included).
The object UIWebView is really versatile and needs very few settings to be used. The only defect is the presence of a mysterious shadow that appears when you make a scroll out of the area of control is at the bottom than at the top:
After several searches I realized that this behavior depends on the SDK, especially the latest updates. And Apple has not released any official statement on how to remove it, on the contrary, he rejected as code is not allowed a series of hacks that make use of sensitive functions, or documenting. Eventually I gave up, both in terms of time, and because the solutions seemed all out of the box Apple.
Fortunately I got the solution, I hope fairly regular basis, which seems to solve the problem (thanks to Adolfo ):
1 2 3 4 5 6 | / / WebView is the control UIWebView [ webView.subviews objectAtIndex : 0 ] ; id = scroller [webView.subviews objectAtIndex: 0]; UIView * subView in [ scroller subviews ] ) for (UIView * subView in [scroller subviews]) subView class ] description ] isEqualToString : @ "UIImageView" ] ) if ([[[subView class] description] isEqualToString: @ "UIImageView"]) ; subView.hidden = YES; |
As pointed out by Adolfo , however this is a hack that may stop working with future releases of the SDK.
Sometimes you just move an item, changing the point of view, to solve a problem seems insurmountable. When one has to do with compatibility between browsers and CSS, inventing solutions "spectacular" (stunts would say) is on the agenda. , per Safari e Google Chrome. What I show you an easy way to apply rounded corners to images using -moz-border-radius , which is available for Mozilla FireFox and -webkit-border-radius , Safari and Google Chrome.
In any browser developed starting from the rendering engine WebKit (by appointment as Safari or Google Chrome ), the fields textarea show, bottom right, the characteristic feature of resizing. If this peculiarity may prove very useful in some cases, in others it becomes a nuisance element.
It's not that I always take it with Internet Explorer, it's just that damn thing every Web development (HTML and CSS) seems not to work with the browser - still - the most common (one day someone will explain why). ; ad esempio ecco come posizionare un div al centro dello schermo: A very convenient method to place an item in the middle of the browser window is to the property sfrutture auto style margin , for example, here is how to position a div in the center of the screen:
I always find some "ill" when tackling the subject "compatibility between browsers." Also, and I have yet to understand the real reason, of all the browsers I know the most "annoying" him remains: Microsoft Internet Explorer 6! Unfortunately, the release of IE 6 is still in circulation and there are frequent reports of problems when viewing pages.
Because of the different rendering across browsers, Microsoft Internet Explorer definitely see that in mind, we must always resort to tricks to apply special effects that now should be a standard. The award-discussed rounded edges are a classic example of "disaster" produced by the complete inability to make a serious standards on page rendering HTML / CSS. , etc… There are many solutions that allow the network to obtain the "effects" (effects of exempting existing HTML as rounded edges, shadow effects, reflections, etc ...) with patches on the leaves of styles, special tricks with the use of div grafted, libraries JavaScript, use of canvas , etc ...
On a purely technical teaching I would like to explain further (cross-browser) to apply the rounded edges of the images:
Mozilla Firefox allows you to manage multiple profiles , which is useful to those who, like me, develops Web sites and requires a series of extensions dedicated to debugging and analysis of Web pages via the use of profiles you can configure different settings FireFox:
Firefox saves your personal information such as bookmarks, passwords and preferences in a file called profile group located in a different position compared to the Firefox program files.
On Windows Vista ( see here for other operating systems) can access the profile management from the command Esegui using:
1 | firefox-ProfileManager |
One of the advantages in the use of profiles is that you can have a FireFox to browse without the toolbar and then all the extensions for debugging and FireFox to develop, accompanied by FireBug and all other development tools.
I just do not ...

Comment Article Net + Television of Tessarolo Thomas , considered by some " [...] a long time , "other" [...] [...] an attempt to justify , "by others" [. ..] [...] resignation ! " But all this could be the real crux of the matter, in my opinion, is far from being gutted! N3TV , the project where I had the good fortune to participate actively, has been a fantastic experience, experienced by all participants with large genuine enthusiasm (I say this because I was there). Not all, unfortunately, myself included, have been able to devote time and resources! I do not deny - and Thomas knows - that the evolution of the project was which seem curious, changing its original form into something that at the end - I think - had little to do with the Web, the so-called Net-Television, in short ! At least he had nothing more to do with the initial premise of the project. But this is normal! An innovative project evolves and changes over time, due to unforeseen events, and is therefore reason to wonder if the initial conditions change.
