A possible enhancement...... about kaprogresslabel HOT 6 CLOSED

It also works quite well programmatically, just make sure you declare your KAProgressLabel as a strong property :

@property (strong,nonatomic)  KAProgressLabel * pLabel;

Then just do as you would with any UILabel :

self.pLabel = [[KAProgressLabel alloc] initWithFrame:CGRectMake(20, 40, 100, 100)];
[self.view addSubview:self.pLabel];

from kaprogresslabel.

Thanks for your response.....
I Know, I have done all these and I get a warning.....in the following method..
self.pLabel1.startLabel.text = [NSString stringWithFormat:@"%.f",self.pLabel1.progress*100];
};
The warning is ....
Capturing 'self' strongly in this block is likely to lead to a retain cycle

and also when I go back in my previous controller my app crashes........

Any ideas?

Thanks again

Just use weakSelf when using self in a block :

__unsafe_unretained Demo1 * weakSelf = self;
self.pLabel.labelVCBlock = ^(KAProgressLabel *label) {
    weakSelf.pLabel.startLabel.text = [NSString stringWithFormat:@"%.f",weakSelf.pLabel.startDegree];
};

You can also use this awesome library to handle retain cycles : https://github.com/jspahrsummers/libextobjc

what is Demo1 in following sentence?

__unsafe_unretained Demo1 * weakSelf = self;

Well this is whatever object holding a reference to the property you need in your block. Usually your UIViewController.
This is pretty basic stuff, you should maybe try this link for more infos on retain cycles : http://www.cocoawithlove.com/2009/07/rules-to-avoid-retain-cycles.html

I'm closing this issue as it is not about the component anymore. You'll find help on StackOverflow if you need to go deeper on this.
