oc中componentsSeparatedByString用法 分割 NSString 返回一个数组NSArray

#import <Foundation/Foundation.h>

int main(int argc, constchar * argv[])
{
    @autoreleasepool {
        //将字符串切割成数组
        NSString *pStr=@"ID:01213221312
@TITLE:nba
@DATE:2007-01-20
@AUTHOR:laowang
@";
        NSArray  *pArr=[pStr componentsSeparatedByString:@"
@"];
        NSString *pStr1=[pArr objectAtIndex:2];
        NSLog(@"%@",pStr1);//DATE:2007-01-20
        NSArray *pArr1=[pStr1 componentsSeparatedByString:@":"];//再次使用componentsSeparatedByString
        NSLog(@"%@",[pArr1 objectAtIndex:1]);//输出第二个元素 2007-01-20  
    }
    return0;
}
