有没有办法获得变量列表和类的功能？
例如：
如果我的课程如下
class Person {
var age: Int!
var name: String!
func isOlder(from person: Person) -> Bool { }
func hasSameName(as person: Person) -> Bool { }
}
我想获得2个名单：
1. [age,name] 2. [isOlder( _ : ),hasSameName( _ : )]
或类似的东西.
谢谢
解决方法
在目标C中
#import <objc/runtime.h>
getDetailsOfClass(Class clz) {
unsigned int methodCount = 0;
Method *methods = class_copyMethodList(clz,&methodCount);
printf("Found %d methods on '%s'\n",methodCount,class_getName(clz));
for (unsigned int i = 0; i < methodCount; i++) {
Method method = methods[i];
printf("\t'%s' has method named '%s' of encoding '%s'\n",class_getName(clz),sel_getName(method_getName(method)),method_getTypeEncoding(method));
}
free(methods);
}
调用：getDetailsOfClass(class)

遵循SO Post.已实施相同并取得成功.
func printMethodNamesForClass(cls: AnyClass) {
var methodCount: UInt32 = 0
let methodList = class_copyMethodList(cls,&methodCount)
if methodList != nil && methodCount > 0 {
enumerateCArray(methodList,methodCount) { i,m in
let name = methodName(m) ?? "unknown"
println("#\(i): \(name)")
}
free(methodList)
}
}
func enumerateCArray<T>(array: UnsafePointer<T>,count: UInt32,f: (UInt32,T) -> ()) {
var ptr = array
for i in 0..<count {
f(i,ptr.memory)
ptr = ptr.successor()
}
}
func methodName(m: Method) -> String? {
let sel = method_getName(m)
let nameCString = sel_getName(sel)
return String.fromCString(nameCString)
}
func printMethodNamesForClassNamed(classname: String) {
// NSClassFromString() is declared to return AnyClass!,but should be AnyClass?
let maybeClass: AnyClass? = NSClassFromString(classname)
if let cls: AnyClass = maybeClass {
printMethodNamesForClass(cls)
}
else {
println("\(classname): no such class")
}
}
快乐编码..
