如何创建水平视图
当用户旋转设备时，我不想改变我的视图，并且我需要视图在初始化时保持水平。
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return NO;
}
- (void)viewDidLoad {
[super viewDidLoad];
[self.view setTransform:CGAffineTransformMakeRotation(M_PI / 2)];
UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(0, 150, 768, 500)];
myView.backgroundColor = [UIColor blueColor];
[self.view addSubview:myView];
}
问题是应用程序启动时视图不靠近左侧。它仍然有一个空白空间。 我设置的Frame是CGRectMake(0, 150, 768, 500)，我不知道原因。 谢谢！
I don't want change my view when user rotate the device, and I need the view to be horizontal when it is initialized.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return NO;
}
- (void)viewDidLoad {
[super viewDidLoad];
[self.view setTransform:CGAffineTransformMakeRotation(M_PI / 2)];
UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(0, 150, 768, 500)];
myView.backgroundColor = [UIColor blueColor];
[self.view addSubview:myView];
}
The problem is the view is not close to left side when the app start. It still have a blank space.
the Frame I set is CGRectMake(0, 150, 768, 500), I don't know the reason.
Thanks!

我无法通过您的问题确定，但是：如果您希望视图处于横向模式，您将需要尝试以下代码：
I can't tell for certain by your question, but: if you want the view to be in landscape mode, you will want to try the following code:
UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(0, 150, 768, 500)];
如果您不旋转视图，则坐标系类似于纵向模式。
尝试
UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(150, 0, 768, 500)];
UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(0, 150, 768, 500)];
If you're not rotating the view, then the coordinate system is like for the portrait mode.
try
UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(150, 0, 768, 500)];
