objective-c - Objective-C : Get Substring between Double Quotes

Question

获取双引号之间的每个子字符串并将其放入数组的最佳方法是什么？

例如，如果字符串(NSString)是:

@"abcd \"efgh\" ijklm \"no\" p \"qrst\" uvwx \"y\" z"

我想要的结果是:

{@"efgh", @"no", @"qrst", @"y"}

作为一个 NSArray。

Answer 1

这应该让你开始:

NSString *str = @"abcd \"efgh\" ijklm \"no\" p \"qrst\" uvwx \"y\" z";
NSMutableArray *target = [NSMutableArray array];
NSScanner *scanner = [NSScanner scannerWithString:str];
NSString *tmp;

while ([scanner isAtEnd] == NO)
{
    [scanner scanUpToString:@"\"" intoString:NULL];
    [scanner scanString:@"\"" intoString:NULL];
    [scanner scanUpToString:@"\"" intoString:&tmp];
    if ([scanner isAtEnd] == NO)
        [target addObject:tmp];
    [scanner scanString:@"\"" intoString:NULL];
}

for (NSString *item in target)
{
    NSLog(@"%@", item);
}
