当我的视图加载以识别我的iDevice的方向时，我遇到了调用void的问题。它只在我的视图旋转时被调用然后它被调用，但我希望它从我的程序的最开始被调用。这就是我所拥有的：
- (void)viewDidLoad {
[super viewDidLoad];
size_t size;
sysctlbyname("hw.machine", NULL, &size, NULL, 0);
char *machine = malloc(size);
sysctlbyname("hw.machine", machine, &size, NULL, 0);
platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];
free(machine);
UIApplication *app = [UIApplication sharedApplication];
UIInterfaceOrientation currentOrientation = app.statusBarOrientation;
[self doLayoutForOrientation:currentOrientation];
}
- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
duration:(NSTimeInterval)duration {
[self doLayoutForOrientation:toInterfaceOrientation];
}
- (void)doLayoutForOrientation:(UIInterfaceOrientation)orientation {
if (UIInterfaceOrientationIsPortrait(orientation)) {
[self layoutPortrait];
} else {
[self layoutLandscape];
}
}
- (void)layoutPortrait {
if ([platform isEqualToString:@"iPhone1,2"] || [platform isEqualToString:@"iPhone2,1"] || [platform isEqualToString:@"iPhone3,1"] || [platform isEqualToString:@"iPhone3,3"] || [platform isEqualToString:@"iPhone4,1"] || [platform isEqualToString:@"iPod1,1"] || [platform isEqualToString:@"iPod2,1"] || [platform isEqualToString:@"iPod3,1"] || [platform isEqualToString:@"iPod4,1"] || [platform isEqualToString:@"iPhone5,1"] || [platform isEqualToString:@"iPhone5,2"] || [platform isEqualToString:@"iPhone5,3"] || [platform isEqualToString:@"iPhone5,4"] || [platform isEqualToString:@"iPhone6,1"] || [platform isEqualToString:@"iPhone6,2"] || [platform isEqualToString:@"iPod5,1"]) {
self.autonomousOnPlayingField.frame = CGRectMake(218, 40, 94, 28);
self.redAutonomousOnPlayingField.frame = CGRectMake(218, 40, 94, 28);

self.autonomousWithAutonomousBallStepper.frame = CGRectMake(218, 74, 94, 29);
self.redAutonomousWithAutonomousBallStepper.frame = CGRectMake(218, 74, 94, 29);

self.redAutonomousCenterGoal.frame = CGRectMake(218, 33, 94, 28);

}
}

}
}
我可以做什么，以便从我的(void)doLayoutForOrientation:(UIInterfaceOrientation)orientation致电(void)viewDidLoad？
