It took me 2 days (and a lot of head/wall pounding) to finally discover that the reason ad-hoc distribution wasn't working for me was because my app-name had UTF-8 characters. I'm still boggling over how such a widely international platform like the Apple iPhone can prohibit this. i.e., if my app were a Chinese game of Go, am I not all...
I have UIWebView within a UIScrollView. Then as I scroll, the web view displays first two pages correctly but does draws only half of the third the page. If I tap on the web view it draws the content or if I call -[UIWebView reload] in -scrollViewDidEndDecelerating, it shows the content. Is there any way I can make the web view draw co...
How can I make the iPhone camera full-screen by removing the overlay? Can I change the camera toolbar style? ...
I'm all for language diversity, but Objective C is insane. So I'm curious: is it possible to code iPhone apps with C++ while using the Cocoa API, etc? ...
Hello, I would like to create an application that downloads a PDF document from the Internet, and displays it to the user. I would like to re-use the iPhone's builtin PDF viewer that is used throughout the core apps to view a PDF document. Is there a way to do that? ...
I'd much rather code an app using pure C api such as OpenGL, rather that Cocoa Touch. So I'm wondering: is it feasible? Will I be able to maintain the same user experience that you get with Interface Builder? ...
I'm reading Erica Sadun's iPhone Developer's Cookbook, and ran into a question. She says in the book that the way to find the user's Documents directory is with the code: [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]; but that seems slightly brittle, and dissimiliar to the normal Mac way of doing it, which would be:...
I have a UITableView cell that is going to have a variable size depending on it's content (potentially several lines of text). SInce it appears that heightForRowAtIndexPath is called before I layout the cell, I just guess the correct height by calling [NSString sizeWithFont] on my text string. Is there a better way to set the height af...
It seems that all of the documentation I can find about OpenGL-ES says something to the effect of "OpenGL-ES is just like OpenGL, but without a lot of stuff. For example, there's no glBegin or glEnd." Ok, that's great. So, what ELSE isn't there any of? Or is there a list of what's in? Or maybe a porting guide? (Specifically, I'm tr...
In XCode, I can use CMD-R to run (or CMD-Y to debug), and my app will compile, install on the phone & start-up. (I've already prepped my phone & XCode so this part works as expected.) What I'd LIKE to do is type CMD-<something else> and have my program compile & install on the phone, but NOT start-up. I realize that I can just CMD-B t...
Sometimes, my UIWebView will have a grey box over part or all of the content. I can't make heads or tails of why it's happening. It happens regularly for certain content. Thanks! --Update-- It seems to occur when the webview is not immediately viewable on the screen -- ie i've got a scrollview, and the webview is below the fold. --U...
I am trying to build an iPhone web application using ASP.NET. The page is dynamically rendered once for each visitor. At this point the page can be bookmarked and it will never change again for that visitor. For this reason it should be cached locally from that point on so the application will run if referenced from the bookmark even if...
Hi all, Has anybody implemented a feature where if the user has not touched the screen for a certain time period, you take a certain action? I'm trying to figure out the best way to do that. There's this somewhat-related method in UIApplication: [UIApplication sharedApplication].idleTimerDisabled; It'd be nice if you instead had som...
In an attempt to hide the Safari UI components for an web-app bookmarked as a Homescreen Icon. I am using this meta tag <meta name="apple-mobile-web-app-capable" content="yes" /> as specified on iPhone Dev Center but the address bar and toolbar are still there when launched from the home screen icon. What do I need to do different? ...
I know that I need to tell my UITextField to resign first responder when I want to dismis the keyboard, but I'm not sure how to know when the user has pressed the "Done" key on the keyboard. Is there a notification I can watch for? ...
I created a project using the default tab-controller project. I am using interface builder to edit the .xib file and add images and buttons. I hook them up to the FirstViewController object in interface builder (that I created and set it's class to the same as the code file). I hooked everything up using IBoutlets and IbActions. Everyt...
Can any one tell me what files I need to submit to the Apple appstore when I submit my application? As an example, do the Resource file, Digital Developer certificate files and others need to be submitted? Please help me understand this process, or show me a resource on the web where I can learn more. ...
I would like to provide two different versions of my iPhone app on the App Store -- one free that is limited by the number of items displayed through the application, and another one completely unlimited. The source code for both apps will be exactly the same, the only difference would be the SQLite database that stores the items in the...
I want to display the "infinity" symbol using CGContextSelectFont(context, "HelveticaNeue", textSize, kCGEncodingMacRoman); CGContextShowTextAtPoint(context, myCenter.x, myCenter.y + textHeight, [sName cStringUsingEncoding:NSMacOSRomanStringEncoding], [sName length]); It is displayed as a square box, or a circle. I have found...
In my app users need to be able to enter numeric values with decimal places. The iPhone doesn't provides a keyboard that's specific for this purpose - only a number pad and a keyboard with numbers and symbols. Is there an easy way to use the latter and prevent any non-numeric input from being entered without having to regex the final re...
