如何將一個圖像的名字從陣列

Question

林分離具有我從數據庫中檢索的圖像陣列，我想要檢索圖像陣列中圖像的名字，我想這一點，它不工作，

- (NSString *)convertToDisplayName 
{ 
    NSMutableString *displayName = [[name mutableCopy] autorelease]; 
    [displayName replaceOccurrencesOfString:@".png" withString:@"" 
    options:NSLiteralSearch range:NSMakeRange(0, displayName.length)]; 
    [displayName replaceOccurrencesOfString:@"_" withString:@" " 
    options:NSLiteralSearch range:NSMakeRange(0, displayName.length)]; 
    return displayName; 
} 

請幫助我。提前感謝？

Answer 1

更小，

- (NSString *) convertToDisplayName:(NSString *) actual 
{ 
    return [[actual stringByReplacingOccurrencesOfString:@".png" withString:@""] stringByReplacingOccurrencesOfString:@"_" withString:@" "]; 
} 

NSLog("@Result : %@",[self convertToDisplayName:@"test_file.png"]); 

結果：測試文件

試試這個代碼行：

- (NSString *)convertToDisplayName 
{ 
    NSMutableString *displayName = [[name mutableCopy] autorelease]; 
    [displayName replaceOccurrencesOfString:@".png" withString:@"" 
    options:0 range:NSMakeRange(0, displayName.length)]; 
    [displayName replaceOccurrencesOfString:@"_" withString:@" " 
    options:0 range:NSMakeRange(0, displayName.length)]; 
    return displayName; 
}
