我的ViewControl上有一个UIButton和UIScrollView(两者都安排在ViewController的顶部)我还有一个UIWebView,它是ViewController的全宽和高度(它设置在后面)

这里是.m文件中的代码,它包括动画,约束和UIwebView网址请求。

#import "ViewController.h"
@interface ViewController ()
@property (strong, nonatomic) IBOutlet UIWebView *webView;
@property (weak, nonatomic) IBOutlet UIWebView *webView2;
@implementation ViewController
@synthesize scrollView;

- (void)viewDidLoad

{

    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

    draw1 = 0;

    scrollView.frame = CGRectMake(0, 300, 480, 55);

    [scrollView setContentSize:CGSizeMake(480, 55)];



    openMenu.frame = CGRectMake(220, 270, 60, 30);

    // stuff************************************************************************************************************************






    [super viewDidLoad];



            UIWebView *webview=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,self.view.frame.size.height)];




    NSString *url=@"http://test.bithumor.co/test26.php";



    NSURL *nsurl=[NSURL URLWithString:url];



    NSURLRequest *nsrequest=[NSURLRequest requestWithURL:nsurl];



    [webview loadRequest:nsrequest];



    [self.view addSubview:webview];

    webview.scrollView.bounces = NO;

    // Do any additional setup after loading the view, typically from a nib.

    UIWebView *webview2=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,self.view.frame.size.height)];

    NSString *url2=@"http://google.com";

    NSURL *nsurl2=[NSURL URLWithString:url2];

    NSURLRequest *nsrequest2=[NSURLRequest requestWithURL:nsurl2];

    [webview2 loadRequest:nsrequest2];

    webview2.scrollView.bounces = NO;





        // stuff************************************************************************************************************************
}

- (void)viewDidAppear:(BOOL)animated

{

    [super viewDidAppear:animated];

    draw1 = 1;

}



- (IBAction)OpenMenu:(id)sender {

    if (draw1 ==0) {

        draw1 = 1;

        [UIView animateWithDuration:0.5

                              delay:0.0

                            options: UIViewAnimationOptionCurveEaseOut


                         animations:^{

                             scrollView.frame = CGRectMake(0, 1000, 568, 200);

                             openMenu.layer.frame = CGRectMake(self.view.center.x - 27, self.view.frame.size.height - 80, 80, 80);

                         }

                         completion:^(BOOL finished){

                             NSLog(@"Done!");

                         }];

    } else {

        draw1 = 0;

        [UIView animateWithDuration:0.5

                              delay:0.0

                            options: UIViewAnimationOptionCurveEaseOut

                         animations:^{

                             scrollView.frame = CGRectMake(0, 300, 568, 200);

                             openMenu.layer.frame = CGRectMake(self.view.center.x - 23, 220, 80, 80);

                         }

                         completion:^(BOOL finished){

                             NSLog(@"Done!");

                         }];

    }

}


@end

问题是当我在模拟器中运行应用程序时,只有UIwebView可见(全屏)

如何制作,以便在UIwebView上方显示UIscrollView和UIButton?

答案 0 :(得分:2)

在viewDidLoad的末尾,尝试将滚动和按钮置于前面

[self.view bringSubviewToFront:webview];
[self.view bringSubviewToFront: openMenu];
