嗨！我需要一种有效的方法来查找字符串是否包含来自另一个字符串的任何字符。我正在尝试查看我的patientView字符串是否包含来自donorView1,2,3等的字符。有没有办法找到我的self.patientView.text字符串是否包含来自我的self.donorView1.text字符串的字符？谢谢！

Answer 1

您似乎希望在带有分隔符的两个字符串中找到常见的字符集。例如，A33, B14, C18, DQ5, DR3, DP1,和A24, B13, C6, DQ3, DR3, DP2,会返回true，因为它们共享DR3。

然而， A33, B14, C18, DQ5, DR3, DP1,和A66, B8, C8, DQ7, DR11, DP2,将返回false，因为该集合不包含匹配项。

如果是这种情况，请尝试以下操作（我清理了您的重新随机代码以取消所有重复：

func commonElements( firstString: String, secondString: String )-> Bool
{
    let firstStringElements = firstString.componentsSeparatedByString(",")
    let secondStringElements = secondString.componentsSeparatedByString(",")

    for  firstStringElement: String in firstStringElements {
        for secondStringElement: String in secondStringElements {
            let string1 =  firstStringElement.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceAndNewlineCharacterSet())
            let string2 =  secondStringElement.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceAndNewlineCharacterSet())
            if string1.lowercaseString == string2.lowercaseString && string1 != ""
            {
                print( "Found match (%@) in strings %@ and %@", string1.lowercaseString, firstString, secondString)
                return true
            }
        }
    }

    return false
}

func randomEntryFromArray( theQuoteArray: [String]) -> String
{
    let randomRange = UInt32(theQuoteArray.count)

    return theQuoteArray [Int(arc4random_uniform(randomRange))]
}

func randomEntriesFromAllArrays() -> String
{
    let quoteArray1 = [" A1,", " A2,", " A3,", " A11,", " A23, ", " A24,", " A25,", " A26,", " A29,", " A30,", " A31,", " A32, ", " A33,", " A34,", " A36, ", " A43,", " A66,", " A68, ", " A69,", " A74,", " A80,",  ]
    let quoteArray2 = [" B7,", " B8,", " B13,", " B14,", " B15, ", " B18,", " B27,", " B35,", " B37,", " B38,", " B39,", " B40,", " B41,", " B42,", " B44,", " B45,", " B46,", " B47,", " B48,", " B49,"," B50,", " B51,", " B52,", " B53,", " B54,", " B55,", " B56,", " B57,", " B58,", " B59,", " B67,"," B73,", " B78,", " B81,", " B82,", " B83," ]
    let quoteArray3 = [" C1,", " C2,", " C3,", " C4,", " C5, ", " C6,", " C7,", " C8,", " C12,", " C14,", " C15,", " C16,", " C17,", " C18," ]
    let quoteArray4 = [" DQ1,", " DQ2,", " DQ3,", " DQ4,", " DQ5,", " DQ6,", " DQ7,", " DQ8,", " DQ9,", ]
    let quoteArray5 = [" DR1,", " DR3,", " DR4,", " DR7,", " DR8,", " DR9,", " DR10,", " DR11,", " DR12,", " DR13,", " DR14,", " DR15,", " DR16,", ]
    let quoteArray6 = [" DP1,", " DP2,"]


    let returnText = randomEntryFromArray(quoteArray1) + randomEntryFromArray(quoteArray2) + randomEntryFromArray(quoteArray3) + randomEntryFromArray(quoteArray4) + randomEntryFromArray(quoteArray5) + randomEntryFromArray(quoteArray6)

    return returnText
