iOS通讯录联系人列表较完整(中文排序)
代码已上传GitHub https://github.com/6357/YUChineseSorting.git
参考http://www.cnblogs.com/syxchina/archive/2012/10/11/2720257.html
一、需要导入头文件pinyin.h这里有下载地址http://download.csdn.net/detail/u013873967/6991579
这是我写的完整代码，欢迎大家学习交流，帮我改进。http://download.csdn.net/detail/u013873967/6992825
二、ChineseString.h
#import <Foundation/Foundation.h> #import "pinyin.h" @interface ChineseString : NSObject @property(strong,nonatomic)NSString *string; @property(strong,nonatomic)NSString *pinYin; //----- 返回tableview右方indexArray +(NSMutableArray*)IndexArray:(NSArray*)stringArr; //----- 返回联系人 +(NSMutableArray*)LetterSortArray:(NSArray*)stringArr; ///---------------------- //返回一组字母排序数组(中英混排) +(NSMutableArray*)SortArray:(NSArray*)stringArr; @end
三、ChineseString.cpp
#import "ChineseString.h"
@implementation ChineseString
@synthesize string;
@synthesize pinYin;
#pragma mark - 返回tableview右方 indexArray
+(NSMutableArray*)IndexArray:(NSArray*)stringArr
{
NSMutableArray *tempArray = [self ReturnSortChineseArrar:stringArr];
NSMutableArray *A_Result = [NSMutableArray array];
NSString *tempString ;
for (NSString* object in tempArray)
{
NSString *pinyin = [((ChineseString*)object).pinYin substringToIndex:1];
//不同
if(![tempString isEqualToString:pinyin])
{
// NSLog(@"IndexArray----->%@",pinyin);
[A_Result addObject:pinyin];
tempString = pinyin;
}
}
return A_Result;
}
#pragma mark - 返回联系人
+(NSMutableArray*)LetterSortArray:(NSArray*)stringArr
{
NSMutableArray *tempArray = [self ReturnSortChineseArrar:stringArr];
NSMutableArray *LetterResult = [NSMutableArray array];
NSMutableArray *item = [NSMutableArray array];
NSString *tempString;
//拼音分组

NSString *string = ((ChineseString*)object).string;
//不同
if(![tempString isEqualToString:pinyin])
{
//分组
item = [NSMutableArray array];
[item addObject:string];
[LetterResult addObject:item];
//遍历
tempString = pinyin;
}else//相同
{
[item addObject:string];
}
}
return LetterResult;
}
///////////////////
//
//返回排序好的字符拼音
//
///////////////////
+(NSMutableArray*)ReturnSortChineseArrar:(NSArray*)stringArr
{
//获取字符串中文字的拼音首字母并与字符串共同存放
NSMutableArray *chineseStringsArray=[NSMutableArray array];
for(int i=0;i<[stringArr count];i++)
{
ChineseString *chineseString = [[ChineseString alloc]init];
chineseString.string = [NSString stringWithString:[stringArr objectAtIndex:i]];
if(chineseString.string == nil){
chineseString.string = @"";
}
//去除两端空格和回车
chineseString.string = [chineseString.string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
//此方法存在一些问题 有些字符过滤不了

//chineseString.string = [chineseString.string stringByTrimmingCharactersInSet:set];
//这里我自己写了一个递归过滤指定字符串 RemoveSpecialCharacter
chineseString.string = [ChineseString RemoveSpecialCharacter:chineseString.string];
// NSLog(@"string====%@",chineseString.string);
//判断首字符是否为字母
NSString *regex = @"[A-Za-z]+";
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex];
NSString *initialStr = [chineseString.string length]?[chineseString.string substringToIndex:1]:@"";

}

}else{

}
}

//按照拼音首字母对这些Strings进行排序
NSArray *sortDescriptors = [NSArray arrayWithObject:[NSSortDescriptor sortDescriptorWithKey:@"pinYin" ascending:YES]];

// }
NSLog(@"-----------------------------");
return chineseStringsArray;
}
#pragma mark - 返回一组字母排序数组
+(NSMutableArray*)SortArray:(NSArray*)stringArr
{
NSMutableArray *tempArray = [self ReturnSortChineseArrar:stringArr];
//把排序好的内容从ChineseString类中提取出来
NSMutableArray *result = [NSMutableArray array];

return result;
}
//过滤指定字符串 里面的指定字符根据自己的需要添加 过滤特殊字符
+(NSString*)RemoveSpecialCharacter: (NSString *)str {
NSRange urgentRange = [str rangeOfCharacterFromSet: [NSCharacterSet characterSetWithCharactersInString: @",.？、 ~￥#&<>《》()[]{}【】^@/￡¤|§¨「」『』￠￢￣~@#&*（）——+|《》$_€"]];
if (urgentRange.location != NSNotFound)
{
return [self RemoveSpecialCharacter:[str stringByReplacingCharactersInRange:urgentRange withString:@""]];
}
return str;
}
四、UITableViewController.cpp
- (void)viewDidLoad
{
self.title = @"我的好友";
[super viewDidLoad];
NSArray *stringsToSort=[NSArray arrayWithObjects:
@"￥hhh, .$",@" ￥Chin ese ",@"开源中国 ",@"www.oschina.net",
@"开源技术",@"社区",@"开发者",@"传播",
@"2013",@"100",@"中国",@"暑假作业",
@"键盘", @"鼠标",@"hello",@"world",
nil];
self.indexArray = [ChineseString IndexArray:stringsToSort];
self.letterResultArr = [ChineseString LetterSortArray:stringsToSort];
}
