心不动则不痛 提交于 2019-12-04 02:38:43
问题 Ugh, having some trouble here... I have 4 display labels in Interface Builder set up as IBOutlets in the view controller. I've set them up with these names label1, label2, label3, label4 I'm want to change the label text for a randomly selected label I'm trying this... In the header file I declare as a property: @property (nonatomic retain) UILabel *myLabel; And then in my implementation file I synthesize and I'm trying myLabel = [UILabel valueForKey: [NSString stringWithFormat:@"label%d",

xcode 4 - custom keyboard

孤人 提交于 2019-12-04 02:17:55
问题 Is there a way to stop the default keyboard and have my custom designed keyboard when user clicks on TextField ? I already designed my buttons to be always available similar to a calculator. It has numbers from 0 to 9 , decimal dot and backspace. 回答1: Starting with iOS 3.2, you can attach any UIView to your UITextField to be used as a keyboard: myTextField.inputView = myFakeKeyboard; You can also attach a toolbar above the keyboard (system or custom one) : myTextField.inputAccessoryView =

Can you batch change per-file compiler flags in Xcode 4?

冷暖自知 提交于 2019-12-04 02:06:52
I'd like to be able to change compiler flags for a whole set of files. When accessing per-file compiler flags from the "Build Phases" area you can change flags one at a time, however say I'd like to change the flags for every file in a group (e.g., the DropBox or Facebook SDK). Anyone know how to do this in Xcode 4.0.x? Fortunately, YES :-) In Targets->Build Phaes->Compile Sources, mark all the files you like to set a compiler flag for, press RETURN (hit the enter key!), put the flag in the upcoming window and you're done! 来源: https://stackoverflow.com/questions/5768855/can-you-batch-change

xCode 4 hangs… what to do?

旧巷老猫 提交于 2019-12-04 01:56:27
xCode 4 started to hang on any project under svn control. I use a remote repository which is accessible and works just fine from a command line. The only work around I was able to find is to kill local svn and checkout the whole project again. That seems to work for a bit but then the same problem shows up: xCode just hangs solid a few seconds after I start it. I would really appreciate any help to resolve this... Can't do anything :( Please and thanks. Log shows the following: 3/22/11 9:53:22 AM Xcode[3295] [?T] ASSERTION FAILURE in /SourceCache/IDEFoundation/IDEFoundation-284/Framework

Good practice to use git together with svn

风流意气都作罢 提交于 2019-12-04 01:31:35
Subversion was popular several years ago, now git is becoming popular and more and more people want to replace Subversion with git. Problem is that a lot projects were based on Subversion. So question is how to use git together with Subversion. Do not replace svn completely, and use git. The simplest way I can figure out is to create git based on the Subversion branch code you have already checked out. Then use git to control locally. After modifications, submit to local git server, then check out to remote server with Subversion. Subversion is just like container to contain git. BTW, I am

NSLog no output in LLDB. Works in GDB

╄→尐↘猪︶ㄣ 提交于 2019-12-04 01:29:46
Since recent update Xcode 4.3 now seems to default to LLDB debugger. I just found that my NSLog statements are not showing in the console. After searching the for answers, finding none, I switched back to GDB and it works fine. I find others mention NSLog in LLDB so I don't' understand why it fails in my case. Should it not work the same? Is there a different method for LLDB? Switching from LLDB back to GDB also worked for me. For those who are not familiar with xcode, to change the runtime debugger back to GDB: Cmd ⌘ + Option ⌥ + R to bring up the pane Change the Debugger to 'GDB' This will

In Xcode4, the new interface builder says “no selection”

旧街凉风 提交于 2019-12-04 00:38:53
I am using the xcode 4.02 for iPhone programming. In the new interface builder, when I click a button (or any other GUI-element) and go to the "attributes inspector" it says "no selection". For a while I thought I could solve the problem by saving the nib-file, but it does not always work. How can I solve this problem? There seems to be a bug in Attributes Inspector in Xcode 4. When this happens to me I usually do this: Switch to another (non IB) file in the current tab Launch a new Tab (cmd T) Open the original IB file in this new tab The Attributes Inspector will magically show in the new
