objective-Cの質問です｡
int main(int argc, const char * argv[])
{
@autoreleasepool {
NSNumber *num1=[[NSNumber alloc]initWithInt:3];
NSNumber *num2=[[NSNumber alloc]initWithInt:1];
NSNumber *num3=[[NSNumber alloc]initWithInt:2];
NSArray *arrNum=[[NSArray alloc]initWithObjects:num1,num2,num3, nil];
NSString *str1=[[NSString alloc]initWithString:@"abc"];
NSString *str2=[[NSString alloc]initWithString:@"ghi"];
NSString *str3=[[NSString alloc]initWithString:@"def"];
NSArray *arrStr=[[NSArray alloc]initWithObjects:str1,str2,str3, nil];
NSArray *arrNumSorted=[arrNum sortedArrayUsingSelector:@selector(compare:)];
NSArray *arrStrSorted=[arrStr sortedArrayUsingSelector:@selector(caseInsensitiveCompare:)];
for (int i=0; i<[arrNumSorted count]; i++) {
NSLog(@"%d",[[arrNumSorted objectAtIndex:i]intValue]);
}
for (int i=0; i<[arrStrSorted count]; i++) {
NSLog(@"%@",[arrStrSorted objectAtIndex:i]);
}
}
return 0;
}
とﾌﾟﾛｸﾞﾗﾐﾝｸﾞをすると､Using 'initWithString:'with a literal is redundantと出てきます｡
なにがいけないのでしょうか･･･｡
教えてください！！
