如何将[AnyHashable: Any]转换为NSmutableDictionary

Question

如标题所述，如何将[AnyHashable: Any]转换为nsmutabledictionary?我需要做一些Obj-c到Swift的关系。

Answer 1

非常直接

var d = [AnyHashable: Any]()
d["name"] = "Jay"
d[0] = "Jay"
print(d)
//[AnyHashable(0): "Jay", AnyHashable("name"): "Jay"]

let nsD = NSDictionary(dictionary: d)
print(nsD)
//{
//    0 = Jay;
//    name = Jay;
//}

let nsMD = NSMutableDictionary(dictionary: d)
print(nsMD)
//{
//    0 = Jay;
//    name = Jay;
//}

桥接的例子:

你的swift类可能看起来像这样

@objc class Swft: NSObject {
@objc var d = [AnyHashable: Any]()

override init() {
super.init()
d["name"] = "jay"
}

@objc func method() ->[AnyHashable: Any] {
return d
}
}

你的Objective-C类可能看起来像这样，.m

#import "Objc.h"
#import "{Your_project_name}-Swift.h"
@interface Objc ()
@end
@implementation Objc
- (void)someMethod {

Swft *s = [[Swft alloc] init];
NSLog(@"1234567890 %@", s.d);
//    1234567890 {
//        name = jay;
//    }
NSLog(@"0987654321 %@", [s method]);
//    0987654321 {
//        name = jay;
//    }
}
@end
