使用toolchain开发iphone程序之连连看

画了几个小时时间，使用cygwin + toolchain做了一个iphone上的简单程序。

很简陋，并且未作过多的刷新等处理。效果如下。

Makefile为：

CC=/usr/local/bin/arm-apple-darwin9-gcc CXX=/usr/local/bin/arm-apple-darwin9-g++ LD=$(CC) CFLAGS=-I/usr/local/lib/gcc/arm-apple-darwin9/4.2.1/include / -isysroot /usr/local/iphone-sysroot LDFLAGS=-framework CoreFoundation -framework CoreGraphics -framework Foundation -framework UIKit -framework GraphicsServices / -lobjc -bind_at_load -isysroot /usr/local/iphone-sysroot all: MyExample MyExample: MyExample.o $(LD) $(LDFLAGS) -o $@ $^ %.o: %.m $(CC) -c $(CFLAGS) $(CPPFLAGS) $< -o $@ clean: rm -rf *.o HelloWorld HelloWorld.app
