解决Xcode中文乱码及GBK转码问题

数组乱码

#import "NSArray+Log.h"
@implementation NSArray (Log)

/**
 解决数组输出中文乱码的问题
 @return 输出结果
 */

- (NSString *)descriptionWithLocale:(id)locale indent:(NSUInteger)level{
    
    NSMutableString *string = [NSMutableString stringWithString:@"[\n"];
    
    [self enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
        for (int i = 0; i <= level; i++) {
            [string appendFormat:@"\t"];
        }
        if ([obj isKindOfClass:[NSDictionary class]] || [obj isKindOfClass:[NSArray class]]) {
            [string appendFormat:@"%@,\n", [obj descriptionWithLocale:locale indent:level +1]];
        } else {
            [string appendFormat:@"%@,\n", obj];
        }
    }];
    //删除末尾的逗号
    if ([string hasSuffix:@",\n"]) {
        [string deleteCharactersInRange:NSMakeRange(string.length - 2, 1)]; // 删除最后一个逗号
    }
    
    for (int i = 0; i < level; i++) {
        [string appendFormat:@"\t"];
    }
    [string appendString:@"]"];
    
    return string;
}

@end

字典乱码

#import "NSDictionary+Log.h"

@implementation NSDictionary (Log)

/**
解决字典输出中文乱码的问题
@return 输出结果
*/

- (NSString *)descriptionWithLocale:(id)locale indent:(NSUInteger)level{

    NSMutableString *string = [NSMutableString stringWithCapacity:42];
    [string appendFormat:@"{\n"];

    [self enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {

        for (int i = 0; i <= level; i++) {
            [string appendFormat:@"\t"];
        }
        
        if ([obj isKindOfClass:[NSDictionary class]] || [obj isKindOfClass:[NSArray class]]) {
            [string appendFormat:@"%@ = %@,\n", key, [obj descriptionWithLocale:locale indent:level +1]];
        } else {
            [string appendFormat:@"%@ = %@,\n", key, obj];
        }
    }];
    
    //删除最后的一个逗号
    if ([string hasSuffix:@",\n"]) {
        [string deleteCharactersInRange:NSMakeRange(string.length - 2, 1)]; // 删除最后一个逗号
    }
       
    for (int i = 0; i < level; i++) {
        [string appendFormat:@"\t"];
    }
    [string appendString:@"}"];

    return string;
}

GBK转码

+ (NSData *)dataWithGBKData:(NSData *)data {
    NSStringEncoding gbk = CFStringConvertEncodingToNSStringEncoding(kCFStringEncodingGB_18030_2000);
    NSString *string = [[NSString alloc] initWithData:data encoding:gbk];
    return  [string dataUsingEncoding:NSUTF8StringEncoding];
}
