iOS开发集成Zbar编译报错

最近用到Zbar，但是集成之后编译，会报以下错误：

"_iconv", referenced from:

_qr_code_data_list_extract_text in libzbar.a(qrdectxt.o)

"_iconv_open", referenced from:

_qr_code_data_list_extract_text in libzbar.a(qrdectxt.o)

"_iconv_close", referenced from:

_qr_code_data_list_extract_text in libzbar.a(qrdectxt.o)

ld: symbol(s) not found for architecture armv7

clang: error: linker command failed with exit code 1 (use -v to see invocation)

1.检查是否导入以下库文件:

AVFoundation.framework

CoreMedia.framework

CoreVideo.framework

QuartzCore.framework

libiconv.tbd

2.检查是否完全导入了sdk。
