-(NSString *)substringToIndex : (NSUInterger) to 获取从字符串开头到字符串的to位置的字符串内容,包含to位置的字符; -(NSString *) substringWithRange:(NSRange) range 根据NSRange这个范围来获取字符串; 事例代码如下:
publicStringsubstring(intbeginIndex)publicStringsubstring(intbeginIndex,intendIndex) 1. 2. 第一种形式的substring方法接受一个整数参数beginIndex,表示截取的起始位置。它将从这个位置开始截取字符串的子串,并返回这个子串。 第二种形式的substring方法接受两个整数参数beginIndex和endIndex,分别表示截取的起始位置和结束位置。
在这个示例中,我们在字符串"This is a sample string."中查找子字符串"sample",输出结果为"Substring found at position 10",表示子字符串"sample"在字符串"This is a sample string."中的位置是第10个字符。 相关搜索: 使用C编程查找字符串中子字符串的出现次数 ...

1. Is the use of strtok strictly necessary, or is required (lecturer's instructions for example), if not, we can try and find other ways to get rid of the spaces and punctuations to build substring, the string reversal process can be done after that. 2. From the original post above,...
