CJA Macros

Collection of daily used Macros in my iOS Projects

Installation

Just drag&drop the CJAMarcos.h file in your Xcode Project. For global usage you can import the CJAMarcos.h in your projects -Prefix.pch file.

Usage

First check out the example Project for further examples

//Should output the current function fingerprint
kNSLogFunction

//Should output the current function fingerprint + the given object description
kNSLogFunctionWithObject(@"My test log");
kNSLogFunctionWithObject(self);

//Use the Error Log to log statements in RELEASE mode
ErrorLog(@"Always print this");

//Localization Shortcut
NSString *localString = _(@"MyTestLocalizationStrinKey");
kNSLogFunctionWithObject(localString);

//Notification Shortcuts
static NSString *testNotificationName = @"TestNotificationName";

addObserver(testNotificationName, self, testNotification:, nil);

notify(testNotificationName, nil, nil);

removeObserver(self);

//Main thread shortcuts
onMainThread(
  //post a notification on the main thread
  kNSLogFunctionWithObject(@"This should be on the Main Thread");
  notify(@"NotificationOnMainThread", nil, nil);
);

//runtime system version checks
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO( _iOS_7_0) ) {
  kNSLogFunctionWithObject(@"Why are on iOS 7")
}

//you can always use the normal NSFoundationVersionNumber's
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO( NSFoundationVersionNumber_iOS_7_0)) {
  kNSLogFunctionWithObject(@"same runtime check as above")
}

if (SYSTEM_VERSION_LESS_THAN( _iOS_7_0) ) {
  kNSLogFunctionWithObject(@"We are on iOS 6, 5, 4, 3 or 2");
}

//Device Checks
if (DEVICE_IS_IPAD) {
	kNSLogFunctionWithObject(@"The current device is an iPad");
}

if (DEVICE_IS_IPHONE) {
	kNSLogFunctionWithObject(@"The current device is an iPhone (incl. iPhone 5 and iPod Touch's)");
}

if (DEVICE_IS_IPHONE_5) {
	kNSLogFunctionWithObject(@"The current device is an iPhone 5 or iPod Touch 5 Gen.");
}

//Declare Constants

//Defines a extern Constant, use it in your .h File
DEFINE_KEY(kTestKey)

//Assign a const value to the Constant, use it in your .m File
DECLARE_KEY(kTestKey)

//Assign a custom const value to the Constant, use it in your .m File
DEFINE_KEY_WITH_VALUE(kNewTestKey, @"CustomValue")

//Test self weak.
CJAWeakSelf;
NSAssert([weakself isEqual:self], @"Objects should be equal");

//Test weak strings.
NSString *text = @"Example";
CJAWeak(text);
NSAssert([weaktext isEqual:text], @"NSString objects should be equal");
    
//Test weak numbers
NSNumber *number = @(1);
CJAWeakWithNameAndObject(number, Number);
NSAssert([weakNumber isEqual:number], @"NSNumber objects should be equal");
