wx.navigateTo、wx.redirectTo、wx.reLaunch、wx.switchTab和wx.navigateBack有什么区别呢？ wx.navigateTo： 用于保留当前页面、跳转到应用内的某个页面，使用 wx.navigateBack可以返回到原页面。对于页面不是特别多的小程序，通常推荐使用 wx.navigateTo进行跳转， 以便返回原页面，以提高加载速度。当页面特别多时，则不推荐使用。 wx.redirectTo： 当页面过多时，被保留页面会挤占微信分配给小程序的内存，或是达到微信所限制的 5 层页面栈。这时应该考虑选择 wx.redirectTo。wx.redirectTo()用于关闭当前页面，跳转到应用内的某个页面。这样的跳转，可以避免跳转前页面占据运行内存，但返回时页面需要重新加载，增加了返回页面的显示时间。 wx.reLaunch： wx.reLaunch()与 wx.redirectTo()的用途基本相同， 只是 wx.reLaunch()先关闭了内存中所有保留的页面，再跳转到目标页面。 wx.switchTab： 对于跳转到 tab bar 的页面，最好选择 wx.switchTab()，它会先关闭所有非 tab bar 的页面。其次，也可以选择 wx.reLaunch()，它也能实现从非 tab bar 跳转到 tab bar，或在

Question: I am actively looking in the source code on Github's facebook-ios-sdk project myself but I was wondering if anyone already knows how to relaunch an app that sent an iPhone user to Safari, such that the user can come back after some work has been finished? Example: When using facebook to login, the original app is relaunched after the facebook login page has authenticated the user. Motivation: I would like to be able to do the same for youtube videos without having to completely lose the user. I don't want to use the standard webview approach because I don't want to provide extra

I want to be able to execute the .Jar file, and if the heap space isn't set big enough, it should launch a new JVM with the same .Jar file, but set with a bigger heap space, and then close the first JVM and .Jar. I've tried using the ProcessBuilder, but I can't get it to work. It has to work cross platform. -ONi I have found the solution, and it works cross platform. To restart the JVM from code, use the following. This answer is taken from another question I found after hours of search in here. If you want, you can follow it with an System.exit(0), to terminate the JVM that started the new
