Simple UIAlert Objective-C class for iOS using UIAlertView (iOS <= 7) or UIAlertViewController (iOS >= 8).
##Some implementation info
Because of ARC and usage of inner action blocks for UIAlertView, ARC removed created message after calling show. To prevent removing this, private singleton class AlertManager is used, that holds references to all created messages until they are closed by clicking on button in them. This class also generates uniques ID for every message.
Second private class is called MyButton and holds info for every added button.
UIAlert class is very simple and try to cover only basic funcionality from UIAlertView. UIAlertViewController is much more flexible - see for example http://nshipster.com/uialertcontroller/ (only in Swift)
Just copy UIAlert/MyAlertMessage.m and UIAlert/ MyAlertMessage.h to your project
MyAlertMessage * a = [[MyAlertMessage alloc] initWithTitle:@"Hello" WithMessage:@"World"];
[a addButton:BUTTON_OK WithTitle:@"OK" WithAction:^(void *action) {
NSLog(@"Button OK at index 0 click");
}];
[a addButton:BUTTON_CANCEL WithTitle:@"Cancel" WithAction:^(void *action) {
NSLog(@"Button Cancel at index 1 click");
}];
[a show];
There are 3 types of Button:
BUTTON_CANCEL- special functionality when addind to alertBUTTON_OKBUTTON_OTHER
OK and OTHER are currently same
On iOS8 ^(void *action) {} action can be cast to UIAlertAction * in action block.
