swift - 在数组项中的字符串末尾添加附加文本

Question

想要在数组项中现有文本的末尾添加附加文本。我到目前为止的代码如下所示:

for var i = 0; i < arrMain.count; i++ {

    if (arrMain[i] as NSString).containsString("#ID-001") {

        println("OK")
        // Add additional text (eg. "Test") at the end of #ID-001 

    }  
}

每个尝试过的组合都会覆盖我#ID-001...

Answer 1

尝试:

var arrMain:[AnyObject] = ["#ID-001"]

for var i = 0; i < arrMain.count; i++ {
    if (arrMain[i] as NSString).containsString("#ID-001") {
        arrMain[i] = (arrMain[i] as String) + "Test"
    }
}
