drawRect is not executing
I have ClockViewController.h and ClockViewController.m inherited from UIViewController.
Also 2 other files ClockView.h and ClockView.m inherited from UIView. In Interface builder i have selected Class "ClockView" for the clock, but my drawRect is not executing. I am calling it via setNeedsDisplay from a timer function. even the timer function is not calling. here is the code ClockViewController.m
import "ClockViewController.h"
@implementation ClockViewController
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
[super viewDidUnload];
}
- (void)dealloc {
[super dealloc];
}
@end
Here is ClockView.m
import "ClockView.h"
@implementation ClockView
-(id)initWithCoder:(NSCoder *)coder{
timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(clockTick) userInfo:nil repeats:YES];
return self;
}
-(id)initWithFrame: (CGRect)frame{
if(self = [super initWithFrame: frame]){
//Initialization code
}
return self;
}
-(void) drawRect: (CGRect)rect{
NSLog(@"from Rect");
}
-(void)clockTick{
NSLog(@"test");
}
-(void)dealloc{
[super dealloc];
}
@end
开发者_如何学Go
Your -initWithCoder: have to call [super initWithCoder:coder].
Also, for consistency, both -initWithCoder: and -initWithFrame: should call the code that installs the timer.
