iOS中常用小东西

1.右滑返回

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
        self.navigationController.interactivePopGestureRecognizer.enabled = YES;
        // 手势有效设置为YES 无效为NO
        self.navigationController.interactivePopGestureRecognizer.delegate = self;
        // 手势的代理设置为self

}

2.禁用第三方键盘

- (BOOL)application:(UIApplication *)application shouldAllowExtensionPointIdentifier:(NSString *)extensionPointIdentifier

{

    if ([extensionPointIdentifier isEqualToString:@"com.apple.keyboard-service"]) {

        return NO;

    }

    return YES;

}

3.改变状态栏颜色

[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

4.画下划线

NSMutableAttributedString *attributedStr = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"点击注册表示已阅读并同意用户服务使用条例"]];
    NSDictionary *dic = @{NSUnderlineStyleAttributeName:[NSNumber numberWithInteger:NSUnderlineStyleSingle]};
    [attributedStr addAttributes:dic range:NSMakeRange(12,8)];
    label1.attributedText = attributedStr;
    label1.textColor = [UIColor whiteColor];
    label1.font = [UIFont systemFontOfSize:14];
    label1.textAlignment = NSTextAlignmentCenter;
    [self.view addSubview:label1];

中间划线，也是相同道理。
