iOS国际化的时候，怎样快速找到需要格式化的中文内容
1，先把项目中的class文件拷贝到iOS模拟器的沙盒中的document目录里面。
2，调用函数dosomething（self.mutableDic里面存的就是我们想要的数据）。
3，将self.mutableDic.allKeys取出来就是你想要的内容。
@interface TwoViewController ()
@property(nonatomic,strong) NSMutableDictionary *mutableDic;
@end
- (void)dosomething{
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDir = [documentPaths objectAtIndex:0];
NSLog(@"%@", documentDir);
[self searchFileWithFilePath:documentDir];
for (NSString *str in self.mutableDic.allKeys) {
NSSLog(@"%@", str);
}
}
- (void)searchFileWithFilePath:(NSString*)filePath{
static NSInteger countss = 0;
static NSInteger countwenjian = 0;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error = nil;
NSArray *fileList = [[NSArray alloc] init];
//fileList便是包含有该文件夹下所有文件的文件名及文件夹名的数组
fileList = [fileManager contentsOfDirectoryAtPath:filePath error:&error];
//以下这段代码则可以列出给定一个文件夹里的所有子文件夹名
BOOL isDir = NO;
//在上面那段程序中获得的fileList中列出文件夹名
for (NSString *file in fileList) {
NSString *path = [filePath stringByAppendingPathComponent:file];
[fileManager fileExistsAtPath:path isDirectory:(&isDir)];
if (isDir) {
// NSLog(@"文件夹：%@ %ld", file, countss++);
// if ([file rangeOfString:@"youqslog"].location != NSNotFound) {
// continue;
// }
// if ([file rangeOfString:@"."].location != NSNotFound) {
// continue;
// }
[self searchFileWithFilePath:path];
}else{
BOOL isPass = YES;
if ([file length] > 1) {
NSString *rearString = [file substringFromIndex:[file length]-2];
if ( [rearString isEqualToString:@".h"] || [rearString isEqualToString:@".m"] || ([file rangeOfString:@".xib"].location!=NSNotFound)) {
isPass = NO;
}
}
if (isPass) {
continue;
}
NSLog(@"文件：%@ %ld", file, countwenjian++);
[self findChinese:path];
}
isDir = NO;
}
}
- (void)findChinese:(NSString*)path{
FILE *fp;
if((fp = fopen(path.UTF8String,"r")) == NULL) //判断文件是否存在及可读
{
printf("error!");
}
while (!feof(fp)) {
char StrLine[2048]; //每行最大读取的字符数
fgets(StrLine, 1024, fp); //读取一行
// printf("%s\n", StrLine); //输出
NSString *searchText = [NSString stringWithUTF8String:StrLine];
NSError *error = NULL;
NSRegularExpression *regex1 = [NSRegularExpression regularExpressionWithPattern:@"@\"[^\"]*[\u4E00-\u9FA5]+[^\"\n]*?\"" options:NSRegularExpressionCaseInsensitive error:&error];
NSRegularExpression *regex2 = [NSRegularExpression regularExpressionWithPattern:@"NSLog.@\"[^\"]*[\u4E00-\u9FA5]+[^\"\n]*?\"" options:NSRegularExpressionCaseInsensitive error:&error];
NSTextCheckingResult *result1 = [regex1 firstMatchInString:searchText options:0 range:NSMakeRange(0, [searchText length])];
NSTextCheckingResult *result2 = [regex2 firstMatchInString:searchText options:0 range:NSMakeRange(0, [searchText length])];
if (result1) {
NSString *zw1 = [searchText substringWithRange:result1.range];
NSString *zw2 = [searchText substringWithRange:result2.range];
if ([zw2 hasPrefix:@"NSLog(@"]) {
NSLog(@"");
}else{
if ([zw1 hasPrefix:@"@"]) {
zw1 = [zw1 substringFromIndex:1];
}
if (zw1) {
[self.mutableDic setObject:zw1 forKey:zw1];
}
}
// NSSLog(@"%@", zw);
}
}
fclose(fp); //关闭文件
}
最后我们再写一个UILabel的Category就可以一键实现国际化了
@implementation UILabel (Swizzle)
+ (void)initialize {
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
[UILabel swizzleSEL:@selector(setText:) withSEL:@selector(setTextHooked:)];
});
}
- (void)setTextHooked:(NSString *)astring
{
NSLog(@"xxx %@ %@",[self class], astring);
NSString *string = NSLocalizedString(astring, nil);
[self setTextHooked:string];
}
