three20

问题 i want to make compatible my apps with iOS 5. Everything goes well with iOS 4.3. After changing the main project and target compiler settings to Apple LLVM compiler 3.0, and set the Three20 project and target settings to LLVM GCC 4.2 i ran the application. Application runs well but at the photo gallery screen there is something which i do not want. There is the screenshot. iOS 5 http://www.portxl.com/ios/5.png There is a rectangular block above the thumbnails. I ran the same application with

问题 There is a blue bar appearing on the top of my tttableview when the program is running on ios 5 beta, it was not there if I run the program on ios 4.3. The table is configured to use a list datasource. Does anyone know what the problem could be? Is it the tableview api changed in someway for ios 5? Thanks. 回答1: It is caused by a subtle but important change Apple made in the UITableView behavior for section headers and footers. If you implement the tableView:viewForHeaderInSection: or

问题 following situation: in a TTTableViewController i added some Cells with URLs. they are opening a class with @"tt://photos" for example. this works quite fine. the first thing is, i saw some urls in TT Examples like @"tt/photos/1". is it possible to fetch this "1" in my photos class and say, for example okay, please open picture one, ore is this only another URL that was declared in TTNavigatior to open a specific Class? the other thing is: is it possible to forward an object to the linked

问题 I need to cache a web-sourced image (i.e. not bundle sourced) that is going into a webview. Normally I'd just request the image and convert it into base-64 and stick it in the HTML, but if I have 100 images in line I can't quite do that. So I searched around a bit and found a way to grab the image request by subclassing NSURLCache and overriding cachedResponseForRequest . My code is below. I'm able to do the request just fine, I can get the data back and print it out, I made a UIImage from

问题 Hi I'm getting an xcode "no such file or directory" for: #import "Three20Core.h" I also note when I'm typing in the #import statement it recognises, and helps autocomplete, the "Three20Core.h" file, however when I compile I get the error? This is the main library file header for the Three20 library (from Facebook). So I've got the three20 directory at the same level as my app directory. In the Xcode application target build settings: Header Search Paths - "$(BUILT_PRODUCTS_DIR)/../../..

问题 in my app i got a TTLauncher Object with some TTLauncherItems in it. Now i want to add some Items dynamically inside my App by pressing a button. Is there a simple way to do that or do i have to create my own methods? In the original facebook application there is already something like that implemented. (You can add your Friends to the Launcher) If not, what would be the best thing to do something like that? Store all "extra items" in a plist oder even in a database and query them, each time

问题 I'm trying to add Three20 to my project, but the -ObjC and -all_load flags are messing with another library I'm using. The other library is ZXingWidget for barcode reading, but I don't think that part is relevant. I'm reasonably sure the answer is to use force_load instead of all_load and then point to my three20 libraries, but I can't get it to work. Here's what i'm using now: -force_load ../facebook-three20/Build/Products/Debug-iphonesimulator/*.a But I get an errno=22 build fail

问题 I've done plenty of iPhone work, never anything with Android. On iPhone, it was a few months in before I discovered the Three20 library (which is awesome) and began moving my code over. I don't want to make the same mistakes moving to Android, so my question: Do android developers commonly use 3rd-party UI/networking libraries like Three20 on iPhone, or do they take the ones out of the box? I realize that there is an effort to port Three20 to Android, but that's not my goal per se. I just
