Hello Iftekhar,

I have integrated your IQActionSheetPickerView in my application. Its working fine. But, when i tried to run the application in iOS7 i faced following warning in my log trace,

I checked your code too. You've not using drawRect method or any CGContext method. But, can't able to find why this warning raising. Facing only on iOS7

Awaiting for your reply.

Did you use initWithFrame method?

[hackiftekhar]

May be @spraveenk is using other method than IQActionSheetPickerView *picker = [[IQActionSheetPickerView alloc] initWithTitle:@"Single Picker" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil, nil];

It is working fine in Sample Project.

Thanks Iftekhar

@spraveenk

you may be getting these issues if you haven't imported QuartzCore

[spraveenk91]

@osrl No. Actually, i have followed the same as per github example.

[spraveenk91]

@hackiftekhar Yes, working only with sample project.

hello: can you tell me how to set default row in a componet? such as set the fifth row in the second componet after init. I try a lot ,but failed.

[hackiftekhar]

@zltqzj

Try selectedTitles property for selecting rows in component.

@property(nonatomic, strong) NSArray *selectedTitles;

You should pass NSArray of NSString to select values in pickerView. Suppose there are 3 rows in pickerView then you should pass NSArray of 3 NSString to select respective rows on pickerView.
