ios - UIScrollView 和 UIButton 不可见
<p><p>我的 ViewControl 上有一个 UIButton 和 UIScrollView(它们都安排在 ViewController 的最顶部)我还有一个 UIWebView，它是 ViewController 的全宽和全高(它设置在最后面)
<br/><br/>这是 .m 文件中的代码，它包括动画、约束和 UIwebView url 请求。<br/><br/></p>
<pre><code>#import "ViewController.h"
@interface ViewController ()
@property (strong, nonatomic) IBOutlet UIWebView *webView;
@property (weak, nonatomic) IBOutlet UIWebView *webView2;
@implementation ViewController
@synthesize scrollView;
- (void)viewDidLoad
{
;
// Do any additional setup after loading the view, typically from a nib.
draw1 = 0;
scrollView.frame = CGRectMake(0, 300, 480, 55);
;
openMenu.frame = CGRectMake(220, 270, 60, 30);
// stuff************************************************************************************************************************
;
UIWebView *webview=[initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,self.view.frame.size.height)];
NSString *url=@"http://test.bithumor.co/test26.php";
NSURL *nsurl=;
NSURLRequest *nsrequest=;
;
;
webview.scrollView.bounces = NO;
// Do any additional setup after loading the view, typically from a nib.
UIWebView *webview2=[initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,self.view.frame.size.height)];
NSString *url2=@"http://google.com";
NSURL *nsurl2=;
NSURLRequest *nsrequest2=;
;
webview2.scrollView.bounces = NO;
// stuff************************************************************************************************************************
}
- (void)viewDidAppear:(BOOL)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;
