从CocoaPods资源包加载图像

标签: ios iphone objective-c xcode cocoapods

我正在创建一个私有库,其中包含库中组件引用的资源。该库与使用CocoaPods的应用程序共享。在库的.podspec中,我包含了这样一行:

s.resource_bundles = {'IXMapKitResources' => ['IXMapKit/Resources/*']}

捆绑包中的一个资源是具有多个图像集的资产目录,其中一个称为“IXMKAnnotationIcons-Normal-Accident”。以下代码返回nil:

UIImage * image = [UIImage imageNamed: @"IXMKAnnotationIcons-Normal-Accident"];

我找到了一个描述如何从pod加载字体的article on mokacoding.com,但这对我不起作用:

- (UIImage *) ixmk_imageNamed: (NSString *) name
{
    NSString * IXMKResourceBundleName = @"IXMapKitResources.bundle";
    NSString * resourceName = [NSString stringWithFormat: @"%@/%@", IXMKResourceBundleName, name];

    NSString * imageTypeString = [self ixmk_stringForImageType: imageType];
    NSURL * url = [[NSBundle mainBundle] URLForResource: resourceName withExtension: imageTypeString];

    NSData * imageData = [NSData dataWithContentsOfURL: url];
    if (imageData != nil)
    {
        CGDataProviderRef provider = CGDataProviderCreateWithCFData((CFDataRef) imageData);
        CGImageRef imageRef = [self ixmk_imageFromDataProvider: provider imageType: imageType];

        UIImage * image = [UIImage imageWithCGImage: imageRef];

        CFRelease(imageRef);
        CFRelease(provider);

        return image;
    }
    else
    {
        return nil;
    }
}

CocoaPods webpage describing the resources keyword有以下警告:

  

我们强烈建议库开发人员采用资源包作为   可以使用resources属性进行名称冲突。此外   使用此属性指定的资源将直接复制到   客户端目标,因此它们没有被Xcode优化。

我不知道该怎么做。

这证明是资产目录的问题,而不是CocoaPods或bundle。将图像移出资产目录可以解决问题。看起来Apple不支持辅助资源包中的资产目录。可惜。

例如Paramount

podspec

s.resource_bundle = {
    'Paramount' => ['Sources/Paramount.bundle/*.png']
}

swift

public extension UIImage {
  static func make(name: String) -> UIImage? {
    let bundle = NSBundle(forClass: Paramount.Toolbar.self)
    return UIImage(named: "Paramount.bundle/\(name)", inBundle: bundle, compatibleWithTraitCollection: nil)
  }
}

此处Paramount.Toolbar.self可以是该框架中的任何类

至于我,我不得不将“s.resources”添加到.podspec中。在此之前失踪。

只有s.resource_bundles以这种方式设置:'BPPicker / Assets / ',也将其更改为'BPPicker / Assets / *'。

#
# Be sure to run `pod lib lint BPPicker.podspec' to ensure this is a
# valid spec before submitting.
#
# Any lines starting with a # are optional, but their use is encouraged
# To learn more about a Podspec see http://guides.cocoapods.org/syntax/podspec.html
#

Pod::Spec.new do |s|
  s.name             = 'BPPicker'
  s.version          = '0.1.11'
  s.summary          = 'This is the imito Body Part Picker.'

# This description is used to generate tags and improve search results.
#   * Think: What does it do? Why did you write it? What is the focus?
#   * Try to keep it short, snappy and to the point.
#   * Write the description between the DESC delimiters below.
#   * Finally, don't worry about the indent, CocoaPods strips it!

  s.description      = <<-DESC
TODO: Add long description of the pod here.
                       DESC

  s.homepage         = 'https://bitbucket.org/imito/bppicker'
  # s.screenshots     = 'www.example.com/screenshots_1', 'www.example.com/screenshots_2'
  s.license          = { :type => 'MIT', :file => 'LICENSE' }
  s.author           = { 'Ievgen Naloiko' => 'naloiko@gmail.com' }
  s.source           = { :git => 'https://ievgen_naloiko@bitbucket.org/imito/bppicker.git', :tag => s.version.to_s }
  # s.social_media_url = 'https://twitter.com/<TWITTER_USERNAME>'

  s.ios.deployment_target = '9.0'

  s.source_files = 'BPPicker/Classes/**/*'

  s.resource_bundles = {
    'BPPicker' => ['BPPicker/Assets/*']
  }
    s.resources = "BPPicker/**/*.{png,json}"

    s.frameworks = 'UIKit'
    s.dependency 'ObjectMapper'
end

我制作了一个可以在pod中找到资源包的pod。 我希望它能结束&#34; CocoaPods资源包&#34;问题一劳永逸。

此答案适用于 Swift3 Swift4

在pod目录下创建一个函数到文件中。

func loadImageBundle(named imageName:String) -> UIImage? {
    let podBundle = Bundle(for: self.classForCoder)
    if let bundleURL = podBundle.url(forResource: "Update with directory name", withExtension: "bundle")
    {
        let imageBundel = Bundle(url:bundleURL )
        let image = UIImage(named: imageName, in: imageBundel, compatibleWith: nil)
        return image
    }
    return nil
}

用法

imageView.image = loadImageBundle(named: "imagefile")

在您的pod文件中:images are in .xcassets so it can be easily organized with 1x, 2x, 3x

s.resources = 'PodName/Assets/**'

用法:Swift

let bundle = Bundle(for: ClassThatWillUseTheImage.self)
let image = UIImage(named: "close", in: bundle, with: .none)

用法:Objective-C

NSBundle *bundle = [NSBundle bundleForClass:[self class]];
UIImage *image = [UIImage imageNamed:@"close" inBundle:bundle withConfiguration:nil];

在版本11.4(11E146)iOS 13.0+中进行了测试

使用#imageLiteral(resourceName: "close")无效,它显示正在读取的图像,但会抛出错误。
