debug

调试模式，会输出运行过程的一些详细信息

example("debug") {
            let bag = DisposeBag()
            var count = 1
            
            let sequenceThatErrors = Observable.create { observer in
                observer.onNext("")
                observer.onNext("")
                observer.onNext("")
                
                if count < 5 {
                    observer.onError(TestError.test)
                    print("Error encountered")
                    count += 1
                }
                
                observer.onNext("")
                observer.onNext("")

                observer.onCompleted()
                
                return Disposables.create()
            }
            
            sequenceThatErrors
                .retry(3)

                .subscribe(onNext: { print($0) })

Resources.total

可以用来查看当前所有的Observable，可便于我们查看某些资源是否释放。

使用其需要做一些特殊操作

cocoaPods

use_frameworks!

target 'RxSwiftDemo' do
    pod 'RxSwift',    '~> 4.0'
    pod 'RxCocoa',    '~> 4.0'
end

post_install do |installer|
    installer.pods_project.targets.each do |target|
        if target.name == 'RxSwift'
            target.build_configurations.each do |config|
                if config.name == 'Debug'
                    config.build_settings['OTHER_SWIFT_FLAGS'] ||= ['-D', 'TRACE_RESOURCES']
                end
            end
        end
    end
end

carthage

carthage build --configuration Debug.

example("RxSwift.Resources.total") {
    print(RxSwift.Resources.total)
    
    let disposeBag = DisposeBag()
    
    print(RxSwift.Resources.total)
    
    let variable = Variable("")
    
    let subscription1 = variable.asObservable().subscribe(onNext: { print($0) })
    
    print(RxSwift.Resources.total)
    
    let subscription2 = variable.asObservable().subscribe(onNext: { print($0) })
    
    print(RxSwift.Resources.total)
    
    subscription1.dispose()
    
    print(RxSwift.Resources.total)
    
    subscription2.dispose()
    
    print(RxSwift.Resources.total)
}
    
print(RxSwift.Resources.total)
