Base on CFRunLoop Timer for iOS.

SYTimer

       

SYTimer is a High performance library for timing. It provides you a chance to use it main runLoop or other runLoop in your next app.

Base on CFRunLoop Timer for iOS.

Features

• All runLoop and runLoopMode Support.
• It's only created two runLoop timer when in main runLoop.
• It's based on priority queue wehn in main runLoop
• ThreadSpecificVariable.
• Heap and HeapItem.

SYTimer

The simplest use-case to setting an timer in main runLoop:

_timer = [SYTimer mainRunLoopTimerWithRunLoopMode:kCFRunLoopCommonModes block:^(SYTimer * _Nonnull) {
    // do 
}];
[_timer startRepeating:.5];

SYTimer will puted ther timer into the runLoopCommonModes heap and set runLoop timer next fire date.

other runLoop:

_otherRunLoopTimer = [[SYTimer alloc] initWithRunLoop:[SYRunLoop current] runLoopMode:kCFRunLoopCommonModes block:^(SYTimer * timer) {
    // do
}];
[_otherRunLoopTimer startRepeating:.5];

Just created runLoop timer and added to current runLoop.

SYHeap

See SYHeap code. It's contained min-heap and max-heap, INCREASE-KEY, DECREASE-KEY. It's used just like NSArray.

SYThreadSpecificVariable

A SYThreadSpecificVariable is a variable that can be read and set like a normal variable except that it holds different variables per thread.

SYHeapItem

An object which it's packaged as SYHeapItem and store it in a heap which it's SYHeap.

Installation

2. Run pod install or pod update.
3. Import <SYTimer/SYTimer.h>.

Requirements

This library requires iOS 10.0+ and Xcode 11.0+.
