我试图沿着字典迭代,以修剪未经证实的条目.以下Objective-C代码的
Swift 3转换不起作用：
原文链接：https://www.f2er.com/swift/319345.html[[self sharingDictionary] enumerateKeysAndObjectsUsingBlock: ^(id key,id obj,BOOL *stop) {
SharingElement* element=[[self sharingDictionary] objectForKey:key];
if (!element.confirmed){
dispatch_async(dispatch_get_main_queue(),^{
[element deleteMe];
});
[[self sharingDictionary] performSelector:@selector(removeObjectForKey:) withObject:key
afterDelay:.2];
} else{
element.confirmed=NO;
}];
所以我尝试以这种方式使用以下紧凑的enumerated()方法：
for (key,element) in self.sharingDictionary.enumerated(){
if (!element.confirmed){
element.deleteMe()
self.perform(#selector(self.removeSharingInArray(key:)),with:key,afterDelay:0.2);
} else{
element.confirmed=false
}
}
然而,编译器在处理变量’element’的使用时报告以下错误：
Value of tuple type ‘(key: Int,value: SharingElement)’ has no member
‘confirmed’
像’元素’一样,完整的元组父亲胜过其能力.
是使用enumerated()或在字典处理中的问题,我该如何解决？
