如何在ios中设置十六进制颜色为文本框边框

Question

UIColor *bgcolour = [BackgroundLayer colorWithHexString:@"F13982"]; 
textField.layer.borderColor=[[UIColor colorWithCGColor:(__bridge CGColorRef)(bgcolour)] CGColor]; 

任何人都可以说如何将UIColor对象“bgcolor”设置为Textfield边框？

Answer 1

textField.layer.borderColor= bgcolour.CGColor; 

Answer 2

首先，你可以使用此功能得到UIColor与Hex字符串

+ (UIColor *)colorFromHexString:(NSString *)hexString { 
     unsigned rgbValue = 0; 
     NSScanner *scanner = [NSScanner scannerWithString:hexString]; 
     [scanner setScanLocation:1]; // bypass '#' character 
     [scanner scanHexInt:&rgbValue]; 
     return [UIColor colorWithRed:((rgbValue & 0xFF0000) >> 16)/255.0 green:((rgbValue & 0xFF00) >> 8)/255.0 blue:(rgbValue & 0xFF)/255.0 alpha:1.0]; 
    } 

和改变边框颜色试试这个

UITextField *theTextFiels=[[UITextField alloc]initWithFrame:CGRectMake(40, 40, 150, 30)]; 
     theTextFiels.borderStyle=UITextBorderStyleNone; 
     theTextFiels.layer.cornerRadius=8.0f; 
     theTextFiels.layer.masksToBounds=YES; 
      theTextFiels.backgroundColor=[UIColor redColor]; 
     theTextFiels.layer.borderColor=[[UIColor blackColor]CGColor]; 
     theTextFiels.layer.borderWidth= 1.0f; 

     [self.view addSubview:theTextFiels]; 
     [theTextFiels release]; 

Answer 3

您按照下面的步骤：

1. 将十六进制值转换为RGB使用HexToRGB。
2. textfield.layer.borderColor=[UIColor colorWithRed:244/255.00f green:133/255.00f blue:116/255.00f alpha:1.0f];

Answer 4

的UIColor + HexColor.h

// 
// UIColor+HexColor.h 
// 

#import <Foundation/Foundation.h> 

@interface UIColor (HexColor) 

//(int) color = RGBA hexadecimal - 8 hexadecimal digits, specifying 8 bits each of red, green, and blue, followed by 8 bits of alpha 
//@usage: UIColor *myColor = [UIColor colorWithHex:0xEEEEEEff]; 
+ (UIColor*) colorWithHex:(int)color; 
@end 

的UIColor + HexColor.m：

// 
// UIColor+HexColor.m 
// 

#import "UIColor+HexColor.h" 

@implementation UIColor (HexColor) 

+ (UIColor*) colorWithHex:(int)color 
{ 

    float red = (color & 0xff000000) >> 24; 
    float green = (color & 0x00ff0000) >> 16; 
    float blue = (color & 0x0000ff00) >> 8; 
    float alpha = (color & 0x000000ff); 

    return [UIColor colorWithRed:red/255.0 green:green/255.0 blue:blue/255.0 alpha:alpha/255.0]; 
} 
@end 

@usage 1（＃F13982）：

textField.layer.borderColor = [UIColor colorWithHex:0xF13982ff]; 

@usage 2（ #eeeeee）：

UIColor *myColor = [UIColor colorWithHex:0xEEEEEEff];
