How to make UI with round image and round text, also add ratting icon on same circle. in iOS application
Solution
Import roundImageView.h class in your view class and set background image on your UIButton. Please change button type Custom.
After Following these steps try this code .
CGRect frame = CGRectMake(0, 0, 200, 200);
roundImageView *roudImage = [[roundImageView alloc]init];
UIImage *image1 = [roudImage createMenuRingWithFrame:frame :@"Your Title" labelBgColor:[UIColor colorWithRed:(191/255.f) green:(251/255.f) blue:(158/255.f) alpha:1] ringBgColor:[UIColor colorWithRed:(214/255.f) green:(214/255.f) blue:(214/255.f) alpha:1] levelUnlockShow:1 buttonObj:yourButtonObj];
[yourButtonObj setImage:image1 forState:UIControlStateNormal];
Note :- In this you can see we set only Image not background image ..
Create a class roundImageView UIImage Type and paste this code
in roundImageView.h file code
#import <UIKit/UIKit.h>
@interface roundImageView : UIImage
- (UIImage*) createMenuRingWithFrame:(CGRect)frame : (NSString*) sectionTitle labelBgColor : (UIColor*)labelBgColor ringBgColor : (UIColor *)ringBgColor levelUnlockShow: (NSInteger) levelUnloackNm buttonObj : (UIButton *)buttonObj;
Paste code in roundImageView.m file
#import "roundImageView.h"
@implementation roundImageView
#define DegreesToRadians(x) (M_PI * x / 180.0)
