私はiPhoneで非常に新しいです。1 つの問題があります。まず、コードを確認してください。

NSString *timeZone=[NSString stringWithFormat:@"%@",[[NSTimeZone systemTimeZone] abbreviation]];
NSLog(@"Print Time Zone :- '%@'",timeZone);
NSRange Timerange=[timeZone rangeOfString:@"+"];
NSString *time;

if(Timerange.location == NSNotFound)
{
    Timerange=[timeZone rangeOfString:@"-"];
    time=[timeZone substringFromIndex:Timerange.location];
    NSLog(@"Time is :- '%@'",time);
    time=[time stringByReplacingOccurrencesOfString:@"-" withString:@"M"];

}
else
{
    Timerange=[timeZone rangeOfString:@"+"];
    time=[timeZone substringFromIndex:Timerange.location];
    NSLog(@"Time is :- '%@'",time);
    time=[time stringByReplacingOccurrencesOfString:@"+" withString:@"P"];
}

iPhone Simulator 4.2 では正常に動作しますが、シミュレータ 4.3 ではクラッシュします。何が問題なのですか?

ありがとう

NSDate *date=[NSDate date]; 
    NSDateFormatter *formatter=[[NSDateFormatter alloc]init]; 
    [formatter setDateFormat:@"MM/dd/yyyy hh:mm:ss a"];
    [formatter setTimeZone:[NSTimeZone systemTimeZone]];

    [formatter setTimeStyle:NSDateFormatterLongStyle]; 

    NSString *dateOfGame =[formatter stringFromDate:date]; 

    NSString *timeZone = [dateOfGame substringFromIndex:12];

    NSLog(@"dateOfGame%@",timeZone);

このコードで試してください

you might need coded like this 

NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@"en_US_POSIX"] autorelease]];
[dateFormatter setDateFormat:@"z"];

NSDate *date = [NSDate date];
NSString *dateString = [dateFormatter stringFromDate:date];
