Question

my code ：
- (void)showWithStatus:(NSString *)status barColor:(UIColor*)barColor textColor:(UIColor*)textColor click:(SEL)click{
if(!self.superview)
[self.overlayWindow addSubview:self];
[self.overlayWindow setHidden:NO];
[self.topBar setHidden:NO];
self.topBar.backgroundColor = barColor;
NSString *labelText = status;
CGRect labelRect = CGRectZero;
CGFloat stringWidth = 0;
CGFloat stringHeight = 0;
if(labelText) {
CGSize stringSize = [labelText sizeWithFont:self.stringLabel.font constrainedToSize:CGSizeMake(self.topBar.frame.size.width, self.topBar.frame.size.height)];
stringWidth = stringSize.width;
stringHeight = stringSize.height;
labelRect = CGRectMake((self.topBar.frame.size.width / 2) - (stringWidth / 2), 0, stringWidth, stringHeight);
}
self.stringLabel.frame = labelRect;
self.stringLabel.alpha = 0.0;
self.stringLabel.hidden = NO;
self.stringLabel.text = labelText;
self.stringLabel.textColor = textColor;
clickBn=[[UIButton alloc]initWithFrame:self.stringLabel.frame];
clickBn.backgroundColor=[UIColor blueColor];
[clickBn addTarget:self action:click forControlEvents:UIControlEventTouchUpInside];
if(!clickBn.superview)
[self.topBar addSubview:clickBn];
[UIView animateWithDuration:0.4 animations:^{
self.stringLabel.alpha = 1.0;
}];
// [self setNeedsDisplay];
}
and call this method:
- (IBAction)successButtonPressed:(id)sender {
[KGStatusBar showSuccessWithStatus:#"Successfully synced" click:#selector(clickBn)];
}
- (void)clickBn {
NSLog(#"sss");
[KGStatusBar dismiss];
}
the NSLog(#"sss") not show. i want to pass a method to UIButton of customView ,but when i click the UIbutton not respond.

Answer 1

Create an delegate in control in .h file before #interface and after header files.
#protocol YourControlDelegate <NSObject>
-(void) delegateMethod;
#end
in #interface
#property (nonatomic,assign) id <YourControlDelegate> yourdelegate;
in .m #synthesize the yourdelegate.
in button click action call [self.yourdelegate delegateMethod];
In your ViewController add YourControlDelegate like as follow
#interface YourVC : UIViewController <YourControlDelegate>
in .m implement the delegate method
-(void) delegateMethod
{
//you code.
}
Here when you click the button the delegateMethod in viewController will be get called.

Answer 2

action should be a selector method.
If you want to pass the button as an argument to the method user : for example
[button addTarget:self action:#selector(buttonClicked:)
forControlEvents:UIControlEventTouchUpInside];
-(void)buttonClicked:(UIButton *)sender
{
//your code and you can also access the button properties using sender.
}
it is preferred. If you don't want to use sender(button) exclude the :

Answer 3

this is your clickBn method right?
- (void)clickBn {
NSLog(#"sss");
[KGStatusBar dismiss];
}
now what you doing in action? action:click??
do like following
clickBn=[[UIButton alloc]initWithFrame:self.stringLabel.frame];
clickBn.backgroundColor=[UIColor blueColor];
[clickBn addTarget:self action:#selector(clickBn) forControlEvents:UIControlEventTouchUpInside];
If you want to call method which is in another class then do like this
first make object of that class
ViewController *dvController = [ViewController alloc] init];
after that [dvController methodName];
do this all in your clickBn method First clickBn method will be called and it will call that another class method which you wanted to call
NOTE: you need to import that class in header
