No format security warnings in Xcode 4.4

阅读更多关于 No format security warnings in Xcode 4.4

问题 I don't get any format security warnings ( -Wformat-security ) from this code using Xcode 4.4: #import <Foundation/Foundation.h> int main(int argc, const char * argv[]) { @autoreleasepool { // a = @"%@" or a = @"%@%@" NSString *a = [@"%@" stringByAppendingFormat:@"%@", arc4random_uniform(2)? @"%@": @"", nil]; // 50% change of crash, but no warning NSLog(a, @"Hello, World!"); } return 0; } Is this normal or have I somehow disabled this warning in Xcode? I have just created the project with

Interface Builder XIB Compiler error

阅读更多关于 Interface Builder XIB Compiler error

I get this error message when connecting two UISwipeGestureRecognizers to a single view in my project inside of a XIB file (though not in a new project, curiously). Anybody know what this error means? It is a compile error, not a runtime error. I'm using Xcode 4.4 (this error doesn't happen on Xcode 4.5 actually). This is an error from inside interface builder.

New Objective-c Literals in 4.4

阅读更多关于 New Objective-c Literals in 4.4

I can write @42 , which creates an NSNumber with int value 42. Can I do this with a variable, like @someIntVar ? Obviously I tried it and it doesn't work (which sucks because then I have to go through [NSNumber numberWithInt:someIntVar] ). Is it possible with a slightly different syntax? Richard J. Ross III I strongly suggest you read the official clang documentation on the matter: http://clang.llvm.org/docs/ObjectiveCLiterals.html But, to box a variable, or any expression, you can use parentheses: id num = @(someIntVar); 来源： https://stackoverflow.com/questions/12120153/new-objective-c

How do I change teams in Xcode 4.4

阅读更多关于 How do I change teams in Xcode 4.4

问题 In 4.3 and under the first time you tried to do a team based action, such as refresh provisioning profiles, it would ask you to log in. It no longer does this in 4.4, it just assumes a team and refreshes... how do I teach Xcode there are multiple teams? It lists them under the teams in side bar of the organizer, but won't let me refresh their profiles, or select them when creating new profiles. To clarify, each team is under a different developer ID, and I can't find any way to log in to

How to make Xcode 4.4 debug console use a popup for autocomplete?

阅读更多关于 How to make Xcode 4.4 debug console use a popup for autocomplete?

问题 I am using Xcode Version 4.4.1 (4F1003) on OSX Mountain Lion 10.8.1 Say you are debugging in Xcode, and you stop at a breakpoint. Then you go to the debug console prompt and start typing po loc ... For me, one of two things will happen: 1.) The console will display a popup with options (the same way autocomplete works in the main text editing window) or 2.) The console will simply automatically autocomplete to the first thing it finds. For example po localeconv() . Even though I was going to

XCode 4.4 iOS 5.1 Simulator problems

阅读更多关于 XCode 4.4 iOS 5.1 Simulator problems

i updated my mac book to mountain lion and Xcode to the 4.4 version. In the pre version I had no problems with closing the iOS simulator and Xcode stopped automatically the building process but now if I close the iOS simulator the build process in Xcode is still running and I have to force quit Xcode because it freezes. Does anyone recognize this bug, or can you help me to solve this problem? As a workaround, I've noticed that Running (⌘ + R) and then Bulding (⌘ + B) product succesfully starts new simulator instance, although the old instances are still frozen. I just reverted to doing

Why doesn't icon composer 2.4 support the 1024x1024 size icon any more?

阅读更多关于 Why doesn't icon composer 2.4 support the 1024x1024 size icon any more?

The icon composer 2.2 in Xcode 4.3.3 supports the icns of 1024x1024. However, for icon composer 2.4, it doesn't support that any more. This is ironic, since Apple pushes for the retina display mbp and requires the newly submitted app to use 1024x1024 icon, but the icon composer doesn't support it any more. Is there any alternative or newly introduced solution by Apple for creating the icon of the size 1024x1024? I really don't understand why Apple is doing this. Thanks! Nick Haddad Icon Composer 2.4 doesn't support 1024x1024 size icons anymore because the workflow for creating application

Xcode 4.4 & 4.5 freezing on project close

阅读更多关于 Xcode 4.4 & 4.5 freezing on project close

Ever since upgrading to Xcode 4.4 and again upgrading to 4.5 (running on Lion), Xcode appears to freeze for about 3-5 minutes every time I close my app project or quit. During this time, activity monitor shows that the CPU is pegged at 95%, although little disk activity is occurring. I have tried uninstalling and re-installing Xcode and this didn't make a difference. Anyone else experiencing this? Any suggestions what I could do? Thanks in advance!
