Xcode compila los errores de .pch? (iOS)

Question

Al realizar cambios en una aplicación de iPhone que guardé y compilé; obtuve los siguientes errores ... deshice todo y ahora estoy atascado con estos errores. Intenté limpiar la construcción, copiar los archivos de esta carpeta, intenté construir en otra máquina. Nada en lo que pueda pensar lo resuelve, el cambio que hice fue en el archivo .xib; Eliminé IBOutlet porque ya no necesitaba el elemento.

¿Alguien sabe cómo puedo resolver estos problemas?> Lo siento por la salida de depuración larga, pero pensé que demasiada información sería mejor que muy poco.

Answer 1

Acabo de encontrar el mismo problema con iOS 4 SDK. Después de que cambié el compilador de compilador LLVM 1.5 a LLVM GCC 4.2 o GCC 4.2, todo volvió OK.

¿Es un error de Clang?

Answer 2

Parece ser un error en el apartado 4.1, por lo que si usted no ha actualizado (todavía) a 4,2, añadir esto a su archivo de prefijo:

#if TARGET_IPHONE_SIMULATOR 
#define __IPHONE_OS_VERSION_MIN_REQUIRED 040100 
#warning "Remove This in SDK 4.2, needed because of a bug in SDK 4.1" 
#endif
