JSON 语法高亮
为 Objective C 中的 JSON 对象添加语法高亮，无论是 Cocoa 还是 iOS，都不需要使用 HTML
需要 ARC
安装
- 将
JSONSyntaxHighlight.m和JSONSyntaxHighlight.h复制到您的项目中 - iOS
- 将
UIKit.framework添加到您的项目中
- 将

用法
- (JSONSyntaxHighlight *)initWithJSON:(id)JSON;创建一个 JSON 对象的 JSONSyntaxHighlight 对象（NSDictionary，NSArray 等）
@property (readonly, nonatomic, strong) id JSON;
@property (readonly, nonatomic, strong) NSString *parsedJSON;JSON 是未经修改的 JSON 对象，parsedJSON 是格式化后的 JSON 字符串
- (NSAttributedString *)highlightJSON;
- (NSAttributedString *)highlightJSONWithPrettyPrint:(BOOL)prettyPrint;返回一个包含高亮 JSON 的格式化文本的 NSAttributedString。如果未指定，则默认是格式化输出
@property (nonatomic, strong) NSDictionary *keyAttributes;
@property (nonatomic, strong) NSDictionary *stringAttributes;
@property (nonatomic, strong) NSDictionary *nonStringAttributes;设置用于 JSON 键和值的 NSAttributedString 的属性（字符串和非字符串）
- (void)enumerateMatchesWithIndentBlock:(void(^)(NSRange, NSString*))indentBlock
keyBlock:(void(^)(NSRange, NSString*))keyBlock
valueBlock:(void(^)(NSRange, NSString*))valueBlock
endBlock:(void(^)(NSRange, NSString*))endBlock为解析 JSON 中找到的每个键项触发一个回调，每个回调都会带有该子串在 self.parsedJSON 中的位置和相应的 NSString
以下是一个包含每个 "键项" 的 JSON 文件示例
{
"name": "dave",
+---++------++----++
| | | |
| | | +-->end (may be empty)
| | +-------->value (will have quotes if string)
| +---------------->key (will have quotes and colon)
+--------------------->indent (leading spaces)
"age": 24
+---++-----++++
| | | |
| | | +------->end @""
| | +--------->value @"24"
| +---------------->key @"\"age\":"
+--------------------->indent @" "
}
+
|
+--------------------->end @"}"
+ (Color *)colorWithRGB:(NSInteger)rgbValue;
+ (Color *)colorWithRGB:(NSInteger)rgbValue alpha:(CGFloat)alpha;这些函数可以根据给定的 rgbValue 返回 NSColor 或 UIColor 对象（具体情况而定）

引入此库
#import "JSONSyntaxHighlight.h"创建 JSONSyntaxHighlight 对象
id JSONObj = @{
@"name": @"dave"
};
JSONSyntaxHighlight *jsh = [[JSONSyntaxHighlight alloc] initWithJSON:JSONObj];
NSAttributedString *s;基本高亮
s = [jsh highlightJSON];
// s => an NSAttributedString with the JSON highlighted in pretty print format
s = [jsh highlightJSONWithPrettyPrint:NO];
// s => same as above, but compressed JSON is returned高级高亮
jsh.nonStringAttributes = @{NSForegroundColorAttributeName: [JSONSyntaxHighlight colorWithRGB:0xffffff]};
jsh.stringAttributes = @{NSForegroundColorAttributeName: [JSONSyntaxHighlight colorWithRGB:0x00ff00]};
jsh.keyAttributes = @{NSForegroundColorAttributeName: [JSONSyntaxHighlight colorWithRGB:0x0000ff]};
s = [jsh highlightJSON];
// s => an NSAttributedString with the JSON highlighted in pretty print format
// using the colors specified above事件驱动 API
NSMutableString *json = [[NSMutableString alloc] initWithString:@""];
[jsh enumerateMatchesWithIndentBlock:
// The indent
^(NSRange range, NSString *s) {
[json appendAttributedString:s];
}
keyBlock:
// The key (with quotes and colon)
^(NSRange range, NSString *s) {
[json appendAttributedString:s];
}
valueBlock:
// The value
^(NSRange range, NSString *s) {
[json appendAttributedString:s];
}
endBlock:
// The final comma, or ending character
^(NSRange range, NSString *s) {
[json appendAttributedString:s];
[json appendAttributedString:@"\n"];
}];
// json => a pretty printed JSON string待办事项
