为数组添加类别
#import "NSArray+ToChinese.h" //类别名称
@implementation NSArray (ToChinese)
- (NSString *)descriptionWithLocale:(id)locale
{
NSMutableString *string=[[NSMutableString alloc]init];
[string appendString:@"("];
for (id obj in self) { //self就是当前可变数组,遍历数组中的对象拼接成新的字符串返回
[string appendFormat:@" %@",obj];
}
[string appendString:@" )"];
return string;
}
@end
为字典添加类别
- (NSString *)descriptionWithLocale:(id)locale
{
NSMutableString *string=[[NSMutableString alloc]init ];
[string appendString:@"{"];
NSString* value=[NSString string];
for (id obj in self) { //self就是当前可变字典,遍历字典中的对象拼接成新的字符串返回
value=[self objectForKey:obj];
[string appendFormat:@" %@ = %@",obj,value];
}
[string appendString:@" }"];
return string;
}
为集合添加类别
- (NSString *)descriptionWithLocale:(id)locale
{
NSMutableString *str=[[NSMutableString alloc]init];
[str appendString:@"("];
