ios oc调用swift framework
1.oc 调用swift
/*oc调用swift, project name为DeomOC: 1.oc工程DemoOC中显式创建一个swift文件,生成DemoOC-Bridging-Header.h 2.#import "DemoOC-Swift.h" https://developer.apple.com/library/content/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html */ #import "DemoOC-Swift.h" - (void)viewDidLoad { [super viewDidLoad]; swifttest *tests = [swifttest new]; NSLog(@"%@", [tests test]); } // swifttest.swift // DemoOC import Foundation class swifttest:NSObject { func test() -> String { return "hi " } }
2.调用swift framework
碰到问题及解决方法:ios dyld: Library not loaded: @rpath/xxx.framework/xxx 之根本原因
oc调用swift framework注意点:
- class 需继承自NSObject,且public属性才能暴露给oc
- 函数名转换规则:swift func foo(para1:...) -> oc fooWithPara1
- oc不支持重载,但根据转换规则可以给第一个参数不同的名字,转换的函数名不一样就可以
- 不支持struct的转换,需用 class
- enum必须为整型才能转换
- 函数返回值不支持tuple
