项目中有引用insta360SDK采集图片,使用opencv库进行图像处理,但是发现图片无法读取,导致后续处理crash
读取图片代码:
cv::imread(@"var/image.png")
cv::resize(123)
crash 截图如下:
resize crash.png
问题原因:
opencv库和insta360SDK冲突
解决办法:修改link顺序
- 1 如果是直接拖入工程引用
修改Build Phases 中 link Binary With Libraries 调整opencv库和insta360SDK顺序 - 2 如果是pod引入(我就是这样的),需要在podfile里写脚本修改
Pods-XXX.debug.xcconfig 中的OTHER_LDFLAGS value中framework顺序,脚本奉上
post_install do |installer|
puts "Updating "
installer.pods_project.targets.each do |target|
puts "Updating "
if target.name == "Pods-CaptureSDKDemo"
puts "Updating #{target.name} OTHER_LDFLAGS"
target.build_configurations.each do |config|
xcconfig_path = config.base_configuration_reference.real_path
# read from xcconfig to build_settings dictionary
build_settings = Hash[*File.read(xcconfig_path).lines.map{|x| x.split(/\s*=\s*/, 2)}.flatten]
# modify OTHER_LDFLAGS
vlc_flag = ' -framework "INSCoreMedia"'
build_settings['OTHER_LDFLAGS'].gsub!(vlc_flag, "")
build_settings['OTHER_LDFLAGS'].gsub!("\n", "")
build_settings['OTHER_LDFLAGS'] += vlc_flag + "\n"
# write build_settings dictionary to xcconfig
File.open(xcconfig_path, "w") do |file|
build_settings.each do |key,value|
file.write(key + " = " + value)
end
end
end
end
end
end
修改.xcconfig详细见链接
