开发小技巧

1. 强制使用系统键盘
- (BOOL)application:(UIApplication *)application shouldAllowExtensionPointIdentifier:(NSString *)extensionPointIdentifier{
    if ([extensionPointIdentifier isEqualToString:@"com.apple.keyboard-service"]) {
        return NO;
    }
    return YES;
}

2.是否锁屏

禁止锁屏：[UIApplication sharedApplication].idleTimerDisabled = YES;

允许锁屏：[UIApplication sharedApplication].idleTimerDisabled = YES;

3.关闭iOS7后手势返回

self.navigationController.interactivePopGestureRecognizer.enabled = NO;
