Question

我在我的视图控制器中创建了一个视图，我希望当我加载该子视图或显示它可能从orignial视图控制器的左侧到右侧时，

 subView = [[UIView alloc] initWithFrame:CGRectMake(20, 125, 560,530)];

[subView setBackgroundColor:[UIColor colorWithRed:216./255 green:238./255 blue:209./255 alpha:1.0]];


UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
backButton.frame = CGRectMake(40,20, 169,42);
UIImage*btnImage = [UIImage imageNamed:@"back.PNG"];

[backButton setImage:btnImage forState:UIControlStateNormal];

[backButton addTarget:self action:@selector(backButtonClicked:) forControlEvents:UIControlEventTouchUpInside];

[subView addSubview:backButton];

[self.view addSubview:subView];

我想在按钮单击时打开此视图我想要在单击按钮时，此视图应从左到右滑动，因为通常会打开新的视图控制器。

subView = [[UIView alloc] initWithFrame:CGRectMake(320, 125, 560,530)];

[subView setBackgroundColor:[UIColor colorWithRed:216./255 green:238./255 blue:209./255 alpha:1.0]];


UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
backButton.frame = CGRectMake(40,20, 169,42);
UIImage*btnImage = [UIImage imageNamed:@"back.PNG"];

[backButton setImage:btnImage forState:UIControlStateNormal];

[backButton addTarget:self action:@selector(backButtonClicked:)     forControlEvents:UIControlEventTouchUpInside];

[subView addSubview:backButton];

[self.view addSubview:subView];

[UIView setAnimationDuration:0.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseOut];

使用UIView动画块

- (IBAction)backButtonClicked:(id)sender {
    [UIView animateWithDuration:1.0f animations:^{
        CGRect frame = CGRectMake(subview.frame.size.width, subview.frame.origin.y, subview.frame.size.width, subview.frame.size.height);
        subview.frame = frame;
    } completion:^(BOOL finished) {
        CGRect frame = CGRectMake(320.0, subview.frame.origin.y, subview.frame.size.width, subview.frame.size.height);
        subview.frame = CGRectMake(20, 125, 560,530);       
    }];
}
