But you might run into problems later with this configuration. First we should understand what problems does the SequenceFile try to solve, and then how can SequenceFile help to solve the problems. The more the number of files is, the more number of Map task need and the job time can be much more slower. For example, suppose there are 10, KB files, then we can write a program to put them into a single SequenceFile like below, where you can use filename to be the key and content to be the value.
Block-Compressed source: csdn. Well, I guess I have finally found the issue: Its definitely memory issue, but I had to search where. When I removed those, my app just work fine!! The issue has been resolved but still I am confused why it did work and still works great in iOS 8.
If it has some issues with memory I found some and fixed already, still , why it did work with iOS 8. So, my advice to any fellow who are having such issues, I recommend using UITextView for links I did it and its nice replacement.
It is usually good practice to use the highest type needed in your code. Therefore if your code needs to read data from an InputStream but not specifically from a FileInputStream , you should use InputStream. Yet if you do need to keep the information of your object being a FileInputStream and not just an InputStream , then you should keep the FileInputStream type. What is Prefix. Or will it crash during build?
A Prefix. Precompiled headers were invented to make compiling faster. Rather than parsing the same header files over and over, these files get parsed once, ahead of time.
But the idea behind a prefix header is different from precompiling. A prefix header is implicitly included at the start of every source file. You can remove the precompiled header. This question has been already answered in thread I'm linking below. It contains all the information you need as well as useful comments. Is it OK to remove Prefix.
Prefix headers are compiled and stored in a cache, and then automatically included in every file during compilation. This can speed up compilation, and lets you include a file without adding an import statement to every file using it. They are not required, and actually slow compilation whenever you change them. You can also remove the value of the Prefix Header setting if you wish. Don't put macros in a.
It really shouldn't be used beyond the context of the project and it really shouldn't contain anything but includes and imports. If you have some macros and such that you want to share between headers, then stick 'em in a header file of their own — Common. From Xcode 6 you should set. The simple mechanism of text inclusion also leads to fragility as names from different headers collide. Precompiled headers are a partial solution to the problem of slow build times.
They speed up the time it takes to compile a project when all or nearly all source files need to include some common headers. This means parsing and compiling the UIKit. A precompiled header file, as the name suggests, collects the common headers into a separate file.
Precompiling this file just once and then automatically including it in all source files in the project significantly speeds up the build process for many projects. Here is a typical Prefix. The ability to have something globally included by placing it in the pch file is a useful but easily abused facility. A Prefix. Precompiled headers were invented to make compiling faster.
