當(dāng)一段數(shù)組里面的字符串,需要進(jìn)行排序的時(shí)候,:原文鏈接

英文通過字母排序:

中文通過拼音排序:

這里有一個(gè)算法,直接使用就可以進(jìn)行排序

-(void)testSort

{ NSArray *stringsArray = [NSArray arrayWithObjects:@"string 1", @"你好",@"你在", @"String 11", @"上海", nil];

? ?static NSStringCompareOptions comparisonOptions = NSCaseInsensitiveSearch | NSNumericSearch | NSWidthInsensitiveSearch | NSForcedOrderingSearch;

????NSLocale *currentLocale = [NSLocale currentLocale];

?????NSComparator finderSortBlock = ^(id string1, id string2) {

??????? NSRange string1Range = NSMakeRange(0, [string1 length]);

??? return [string1 compare:string2 options:comparisonOptions range:string1Range locale:currentLocale];

??? };

??? NSArray *finderSortArray = [stringsArray sortedArrayUsingComparator:finderSortBlock];

??? NSLog(@"finderSortArray: %@", finderSortArray);

}

輸出結(jié)果：

<__NSArrayI 0x109622d90>(

你好,

你在,

上海,

string 1,

String 11

)
