2、获取当前类的名称 String.fromCString(object_getClassName(self)) 注意:通过_stdlib_getDemangledTypeName也能取到,但是如果在父类里面去就只能取到父类的名称 3、 国际化 find. \( -name'*.m'-o -name'*.h'\) -print0 |xargs-0genstrings -o en.lproj 凡是使用了NSLocalizedString的字符串都能被找到...
如果想从[CChar]数组中获取一上String字符串,则可以使用String的fromCString方法,其声明如下: 1 2 3 4 5 6 7 /// Creates a new `String` by copying the nul-terminated UTF-8 data /// referenced by a `CString`. /// /// Returns `nil` if the `CString` is `NULL` or if it contains il...

而在Swift编程语言中,由于一般数组(Array)对象都无法直接用于C语言中含有指针类型的函数参数(比如:void*),所以往往需要将数组转为指针类型,此外也需要将数组中元素内容存放到连续的存储空间。此外,Swift中的字符串对象都是String结构体对象,因此也需要将它们转换为C语言中const char *类型相兼容的类型,因此这里将给大...
首先定义一个String类型。 letstring="hello, world" 接下来,我们把它转换成cString,重新赋值。 letcString=string.cString(using:.utf8)! 因为我们知道转换必定能成功,所以这里用了“!”,常规情况编码请注意做好nil防护。 我们截取字符串的前五个字符。
