我正在尝试在联系人列表中获取某人的电话号码,并且在尝试比较两个CFString时遇到问题,因为我似乎无法迅速找到kCFCompareEqualTo属性

在ObjectiveC中,您可以执行以下操作:

ABMultiValueRef phonesRef = ABRecordCopyValue(person, kABPersonPhoneProperty);

for (int i=0; i < ABMultiValueGetCount(phonesRef); i++) {
    CFStringRef currentPhoneLabel = ABMultiValueCopyLabelAtIndex(phonesRef, i);
    CFStringRef currentPhoneValue = ABMultiValueCopyValueAtIndex(phonesRef, i);

    if (CFStringCompare(currentPhoneLabel, kABPersonPhoneMobileLabel, 0) == kCFCompareEqualTo) {
        [contactInfoDict setObject:(__bridge NSString *)currentPhoneValue forKey:@"mobileNumber"];
    }

我尝试过这样的事情:
    var phoneRef :ABMultiValueRef = ABRecordCopyValue(person, kABPersonPhoneProperty).takeRetainedValue()
    var i = 0
    for i ; i < ABMultiValueGetCount(phoneRef) ; i++ {

        var currentPhoneLabel : CFString = ABMultiValueCopyLabelAtIndex(phoneRef, i).takeRetainedValue()
        var currentPhoneValue : CFString = ABMultiValueCopyValueAtIndex(phoneRef, i).takeRetainedValue() as CFString

        if ( CFStringCompare(currentPhoneLabel, kABPersonPhoneMobileLabel, 0) == ???)  {

        }

    }

你能告诉我如何解决这个问题吗?

编辑:
我尝试了这个,现在它并没有失败
var smth = CFStringCompare(currentPhoneLabel, kABPersonPhoneMobileLabel,CFStringCompareFlags.CompareCaseInsensitive) as CFComparisonResult
if  smth == CFComparisonResult.CompareEqualTo   {

}

最佳答案

尝试这个:

if ( CFStringCompare(currentPhoneLabel, kABPersonPhoneMobileLabel, 0) == CFComparisonResult.CompareEqualTo)  {

}

希望这可以帮助.. :)

关于ios - kCFCompareEqualTo不能立即使用吗?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/25481459/
