当我使用NSASCIIStringEncoding为GET请求编码一些中文字符时.

NSLog(@"%@",searchText);
NSString *stringForSearch = [searchText stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];
NSLog(@"%@",stringForSearch);

第一个日志是一个中文字符,但第二个日志总是(null),请帮我这个,谢谢你提前.

视图控制器:

@implementation PaiLifeViewController
@synthesize detail = _detail;
- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    UIImage *i = [UIImage imageNamed:@"menu_patcode_normal"];
    UIButton *c1 = [[UIButton alloc] init];
    c1.tag = 11;
    UIButton *c2 = [[UIButton alloc] init];
    c2.tag = 12;
    UIButton *c3 = [[UIButton alloc] init];
    c3.tag = 13;
    UIButton *c4 = [[UIButton alloc] init];
    c4.tag = 21;
    UIButton *c5 = [[UIButton alloc] init];
    c5.tag = 22;
    UIButton *c6 = [[UIButton alloc] …

我使用NSTimer进行自动幻灯片,我的代码是这样的:

            NSTimer *timer;
            timer = [NSTimer scheduledTimerWithTimeInterval: 5
                                                     target: self
                                                   selector: @selector(handleTimer)
                                                   userInfo: nil
                                                    repeats: YES];
            - (void)handleTimer
            {
                int page = _bannerScrollView.contentOffset.x / 296;

                if ( page + 1 < [array count] )
                {
                    page++;
                    _pageControl.currentPage = page++;
                 }
                else 
                {
                    page = 0;
                    _pageControl.currentPage = page;
                }
                [self changePage];  
            }
            - (void)changePage
            {
                int page = _pageControl.currentPage;
                [_bannerScrollView setContentOffset:CGPointMake(296 * page, 0)];
            }

我需要一些动画,因为它很酷.我怎样才能做到这一点？非常感谢你.

@interface ViewController ()<UITextViewDelegate>


- (void)viewDidLoad
{
    [super viewDidLoad];
    NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:@"www.google.com"];
    NSDictionary *linkDic = @{ NSLinkAttributeName : [NSURL URLWithString:@"http://www.google.com"] };
    [str setAttributes:linkDic range:[[str string] rangeOfString:@"www.google.com"]];
    _textView.attributedText = str;
}


- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange
{
    NSLog(@"=============%@",URL);
    return YES;
}

有什么不对？

我正在使用ASIHTTPRequest [request startAsynchronous]functon向我的webservice api发送请求以登录.如果请求正常,则返回json值.然后我发送另一个请求来获取用户的信息,但在这里我收到一个错误.

这是我的代码:

-(void)login
{
    [usernameTextField resignFirstResponder];
    [passwordTextField resignFirstResponder];

    username = [usernameTextField text];
    password = [passwordTextField text];

    if ( ([username length] == 0 ) || ([password length] == 0 )) 
    {
       ...
    }
    else
    {
        NSString *URL = [NSString stringWithFormat:@"https://xxx.xxx.xx.xx/FMS/Pages/Service/FMService.svc/Login?user=%@&pass=%@",username,password];
        NSURL *requestURL = [NSURL URLWithString:URL];
        ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:requestURL];
        [request setValidatesSecureCertificate:NO];
        [request setDelegate:self];
        [request startAsynchronous];
    }
}

- (void)requestFinished:(ASIHTTPRequest *)request
{
    NSError *error = [request error];
    if (!error) 
    {
        NSString *responseString = [request responseString];
        NSDictionary *responseDict …

我的视图控制器中只有一个UITableView,我的代码是:

@interface MyViewController ()<UITableViewDataSource,UITableViewDelegate>

self.tableView = [[UITableView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, [UIScreen mainScreen].bounds.size.height) style:UITableViewStylePlain];
self.tableView.delegate = self;
self.tableView.dataSource = self;
self.tableView.scrollsToTop = YES;
[self.view addSubview:self.tableView];

它甚至没有运行:

- (BOOL) scrollViewShouldScrollToTop:(UIScrollView*) scrollView

我不知道为什么,我该如何解决这个问题？非常感谢你.
