iphone 上的 NSScanner 简单问题

发布于 2024-10-14 21:18:11 字数 759 浏览 1 评论 0原文

我的字符串是 k= /Users/applefan/Library/Application Support/iPhone Simulator/3.1.3/Applications/422B3239-F521-4985-89FE-EC778C57C0AB/Documents/1.sql

现在如何获取1 from 1.sql

我做了类似的事情，

            NSScanner *scanner = [NSScanner scannerWithString:storePath];
        [scanner scanUpToString:@".sql" intoString:&k]  ;           
            NSLog(@"test is %@",k);

我也这样做了，

unsigned int intValue;

                while([scanner isAtEnd] == NO) {
                    [scanner scanHexInt:&intValue];
                    NSLog(@"HEX : %d", intValue);       
                **}

它给了我所有的 int 值**，

但我只想要 /Documents/ 之后的数值

        [scanner scanUpToString:@".sql" intoString:&k]  ;           
            NSLog(@"test is %@",k);

i did this also

unsigned int intValue;

                while([scanner isAtEnd] == NO) {
                    [scanner scanHexInt:&intValue];
                    NSLog(@"HEX : %d", intValue);

NSString *k = @"/Users/applefan/Library/Application Support/iPhone Simulator/3.1.3/Applications/422B3239-F521-4985-89FE-EC778C57C0AB/Documents/1.sql";
NSString *one = [[[[k componentsSeparatedByString:@"Documents/"] objectAtIndex:1] 
   componentsSeparatedByString:@".sql"] objectAtIndex:0];
NSLog(@"Is it one? %@", one);
