的iOS UTC字符串轉換爲本地日期

Question

代碼：

NSDateFormatter *fmt = [[NSDateFormatter alloc] init]; 
    fmt.dateFormat = @"yyyy-MM-dd HH:mm:ss"; 
    NSDate *utc = [fmt dateFromString:strTime]; 

    NSTimeZone *tz = [NSTimeZone defaultTimeZone]; 
    NSInteger seconds = [tz secondsFromGMTForDate: utc]; 

    NSDate *localdate = [NSDate dateWithTimeInterval:seconds sinceDate:utc]; 
    NSString *local = [fmt stringFromDate:localdate]; 
    NSLog(@"local time%@", local); 

    NSDate *localDate = [fmt dateFromString:local]; 

我從服務器獲取UTC字符串。我成功地轉換爲本地字符串，然後我嘗試將其轉換爲本地日期。但日期是UTC format.what顯示是錯我的代碼任何幫助將是appreciated.thanks提前

嘗試了這一點：

NSDateFormatter *fmt = [[NSDateFormatter alloc] init]; 
fmt.dateFormat = @"yyyy-MM-dd HH:mm:ss"; 
NSDate *utc = [fmt dateFromString:<Your_UTC_String>]; 
fmt.timeZone = [NSTimeZone systemTimeZone]; 
NSString *local = [fmt stringFromDate:utc]; 
NSLog(@"%@", local);
