完整代码：

@implementation ClassForSelectors
- (void) fooNoInputs {

NSLog(@"Does nothing");

}

- (void) fooOneIput:(NSString*) first {

NSLog(@"Logs %@", first);

}

- (void) fooFirstInput:(NSString*) first secondInput:(NSString*) second {

NSLog(@"Logs %@ then %@", first, second);

}

 

- (NSArray *)abcWithAAA: (NSNumber *)number {

int primaryKey = [number intValue];

NSLog("%i", primaryKey);

}

 

- (void) performMethodsViaSelectors {

[self performSelector:@selector(fooNoInputs)];

[self performSelector:@selector(fooOneInput:) withObject:@"first"];

[self performSelector:@selector(fooFirstInput:secondInput:) withObject:@"first"withObject:@"second"];

}

 

- (void) performDynamicMethodsViaSelectors {

MethodForSelectors * mfs = [MethodForSelectors alloc];

NSArray *Arrays = [NSArray arrayWithObjects:@"AAA", @"BBB", nil];

for ( NSString *array in Arrays ){

SEL customSelector = NSSelectorFromString([NSStringstringWithFormat:@"abcWith%@:", array]);

mfs = [[MethodForSelectors alloc] performSelector:customSelector withObject:0];

}

}

@end

 

@implementation MethodForSelectors

- (void)abcWithAAA: (NSNumber *)number {

NSLog("%i", number);

}

@end
