Question

我刚刚开始为iOS编程。我尝试为一个简单的计算器添加一个输入按钮并改变它的大小，但Xcode不断崩溃。这是报告：

Process:         Xcode [406]
Path:            /Applications/Xcode.app/Contents/MacOS/Xcode
Identifier:      com.apple.dt.Xcode
Version:         4.5.1 (1842)

Crashed Thread:  0  Dispatch queue: com.apple.main-thread

Exception Type:  EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000

Application Specific Information:
ProductBuildVersion: 4G1004
ASSERTION FAILURE in /SourceCache/IDEInterfaceBuilderCocoaTouch/IDEInterfaceBuilderCocoaTouch-1929/IBPlugin/Utilities/IBObjectMarshalling.m:651
Details:  Failed to arbitrate IBNSLayoutConstraint, IBUIButton, IBUILabel, IBUIView, and IBUIViewController.

Interface Builder encountered an error communicating with the iOS Simulator. If you choose to file a crash report or radar for this issue, please check Console.app for crash reports for "Interface Builder Cocoa Touch Tool" and include their content in your crash report.

Exception name: IBAssertionFailure
Exception reason: ASSERTION FAILURE: 
Reason:     All views needing candidate constraints have already had constraints generated. This most likely indicates a bug involving layout of the following views:
    Layout engine frame ({{20, 20}, {282, 36}}) of <UILabel: 0x81f5560; frame = (20 20; 281 36); text = '0'; clipsToBounds = YES; opaque = NO; autoresize = TM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x815cdd0>> does not match canvas frame ({{20, 20}, {281, 36}})

我已经尝试重新安装Xcode并重置iOS模拟器。我有山狮。
